Association between healthy lifestyle and memory decline in older adults: 10 year, population based, prospective cohort study

Abstract

Objective To identify an optimal lifestyle profile to protect against memory loss in older individuals.

Design Population based, prospective cohort study.

Setting Participants from areas representative of the north, south, and west of China.

Participants Individuals aged 60 years or older who had normal cognition and underwent apolipoprotein E (APOE) genotyping at baseline in 2009.

Main outcome measures Participants were followed up until death, discontinuation, or 26 December 2019. Six healthy lifestyle factors were assessed: a healthy diet (adherence to the recommended intake of at least 7 of 12 eligible food items), regular physical exercise (≥150 min of moderate intensity or ≥75 min of vigorous intensity, per week), active social contact (≥twice per week), active cognitive activity (≥twice per week), never or previously smoked, and never drinking alcohol. Participants were categorised into the favourable group if they had four to six healthy lifestyle factors, into the average group for two to three factors, and into the unfavourable group for zero to one factor. Memory function was assessed using the World Health Organization/University of California-Los Angeles Auditory Verbal Learning Test, and global cognition was assessed via the Mini-Mental State Examination. Linear mixed models were used to explore the impact of lifestyle factors on memory in the study sample.

Results 29 072 participants were included (mean age of 72.23 years; 48.54{bf0515afdcaddba073662ceb89fbb62b6b1bf123143c0e06b788e1946e8c353f} (n=14 113) were women; and 20.43{bf0515afdcaddba073662ceb89fbb62b6b1bf123143c0e06b788e1946e8c353f} (n=5939) were APOE ε4 carriers). Over the 10 year follow-up period (2009-19), participants in the favourable group had slower memory decline than those in the unfavourable group (by 0.028 points/year, 95{bf0515afdcaddba073662ceb89fbb62b6b1bf123143c0e06b788e1946e8c353f} confidence interval 0.023 to 0.032, P<0.001). APOE ε4 carriers with favourable (0.027, 95{bf0515afdcaddba073662ceb89fbb62b6b1bf123143c0e06b788e1946e8c353f} confidence interval 0.023 to 0.031) and average (0.014, 0.010 to 0.019) lifestyles exhibited a slower memory decline than those with unfavourable lifestyles. Among people who were not carriers of APOE ε4, similar results were observed among participants in the favourable (0.029 points/year, 95{bf0515afdcaddba073662ceb89fbb62b6b1bf123143c0e06b788e1946e8c353f} confidence interval 0.019 to 0.039) and average (0.019, 0.011 to 0.027) groups compared with those in the unfavourable group. APOE ε4 status and lifestyle profiles did not show a significant interaction effect on memory decline (P=0.52).

Conclusion A healthy lifestyle is associated with slower memory decline, even in the presence of the APOE ε4 allele. This study might offer important information to protect older adults against memory decline.

Introduction

Although a fundamental function of daily life, memory continuously declines as people age,1 impairing both life quality and work productivity and increasing the risk of dementia.234 However, age related memory decline is not always a prodrome of dementia; memory loss can merely be senescent forgetfulness, which is more prevalent among older individuals, and can be reversed or become stable rather than progress to a pathological state.5 Thus, the prevention and slowing of age related memory decline in older individuals is paramount. Fortunately, memory decline can be mutable because various contributing factors are reportedly associated with memory loss.

Studies have been conducted to identify factors that might affect memory, including ageing, the apolipoprotein E (APOE) ε4 genotype, chronic diseases, and lifestyle patterns.67 Among these, lifestyle has received increasing attention as a modifiable behaviour because this factor is relatively easily amendable with potential benefits for overall health as well as memory. Studies on the effect of a healthy lifestyle on cognition are increasing.89101112 However, few studies have focused on its effect on memory, and most were cross sectional in nature,13 which is insufficient to evaluate the relationship between a long term healthy lifestyle and memory decline. Additionally, those studies did not consider the interaction between a healthy lifestyle and genetic risk; thus, the exact effect of a healthy lifestyle on memory decline in individuals with a higher genetic risk remains unknown. Therefore, longitudinal studies are needed to further investigate the effect of modifiable lifestyle factors on memory decline in older individuals, considering genetic risks, such as the presence of an APOE ε4 genotype.

We used data from a large population based cohort (the China Cognition and Ageing Study; COAST) to investigate whether adherence to a combination of healthy lifestyle factors was associated with a slower memory decline in cognitively normal older adults, even those genetically susceptible to memory decline.

Methods

Study design and participants

The COAST is a nationwide, population based, cohort study on dementia in China (ClinicalTrials.gov identifier: NCT03653156). This investigation included individuals from 12 provinces from the north, south, and west of China, representing the geographical characteristics, degree of urbanisation, economic status, dietary patterns, and cultural and social differences in China. We conducted a multistage, stratified, cluster sampling procedure, which considered sex and age distribution, among these provinces. A total of 96 study sites (48 urban and 48 rural) were randomly selected (supplementary 1). Written or oral informed consent was obtained from all participants.

The study enrolment procedure began on 8 May 2009 and comprised two sequential phases (lasting about six months together). In phase 1, individuals aged 60 years or older, who gave consent to participate in the study, were listed in the community census or village registry, and had resided there for at least one year preceding the survey date, were included in the study. We excluded participants with a life threatening disease, hearing loss, or vision loss. In phase 2, participants from phase 1 with available APOE genotyping and without mild cognitive impairment or dementia were included. Four rounds of follow-up were conducted—ie, a follow-up any time in 2012, 2014, 2016, and 2019. The end date of the study was 26 December 2019.

Diagnosis of dementia and mild cognitive impairment

The aim of this study was to investigate the association between lifestyle and memory in participants with normal cognitive function throughout the study period. Neuropsychological tests were done to determine the cognitive status of the participants at baseline and at each follow-up. For people who progressed to mild cognitive impairment or dementia during the follow-up period, the data after their diagnosis were excluded in the main analyses. Global cognitive function was assessed using the Mini-Mental State Examination,14 which evaluates orientation, attention, calculation, executive function, language, among others. The total score of the Mini-Mental State Examination ranges from 0 to 30, with higher scores representing a better cognitive function. Participants whose score was less than 26 were suspected of cognitive impairment and would receive further evaluation, including physical and other neuropsychological testing. The results and participants’ medical records were reviewed by neurologists who were masked to the genetic results. Dementia was diagnosed on the consensus of at least two neurologists, according to the Diagnostic and Statistical Manual of Mental Disorders (4th edition, text revision criteria).15 Mild cognitive impairment was diagnosed according to the Peterson criteria.16 Having normal cognitive function was defined as having a score of 0 for the Clinical Dementia Rating.17 People for whom a consensus could not be reached were considered controversial cases. These cases would be discussed and diagnosed by an expert group, which included senior neurologists, psychiatrists, and neuropsychologists.

Assessment of lifestyle factors

Lifestyle information was collected at baseline and each follow-up based on each individual’s performance over the past year through a healthy behaviour questionnaire (supplementary 2). We assessed lifestyle status by six modifiable lifestyle factors: physical exercise, diet, drinking, smoking, cognitive activity, and social contact. For physical exercise, weekly frequency and total time were collected, and at least 150 min of moderate or 75 min of vigorous activity per week was considered a healthy factor, according to the American guidelines for physical activity in adults.18 For smoking, participants were categorised as smokes current, never (participants who had smoked <100 cigarettes in their lifetime) smokes, or used to smoke (participants who had quit smoking at least three years before). Never or former smoking was deemed a healthy lifestyle factor.19 For alcohol consumption, the current frequency and volume of alcohol consumption were recorded, and individuals were categorised into never drinking (never drank or drank occasionally), low to excess drinking (daily alcohol consumption of 1-60 g), and heavy drinking (daily alcohol consumption >60 g).20 The category of never drinking was deemed a healthy lifestyle factor.21 The remaining three lifestyle factors were deemed healthy based on the top 40{bf0515afdcaddba073662ceb89fbb62b6b1bf123143c0e06b788e1946e8c353f} of the population distribution, according to previous studies.22232425 For diet, we recorded the participant’s daily intake of 12 food items (fruits, vegetables, fish, meat, dairy products, salt, oil, eggs, cereals, legumes, nuts, and tea) (supplementary 2).26 For cognitive activity (writing, reading, playing cards, mahjong, and other games) and social contact (participation in meetings or attending parties, visiting friends or relatives, travelling, and chatting online), engagement frequencies were investigated. Ultimately, these factors were deemed healthy when participants consumed appropriate daily amounts of at least 7 of the 12 food items for diet, and they engaged in cognitive activity or social contact at least twice weekly in this study.

We evaluated the association of each single lifestyle factor with memory function. For further investigation of the combined effect of lifestyle factors on memory function, we categorised participants into three groups based on the third of the number of healthy lifestyle factors: favourable (4-6 healthy factors), average (2-3), and unfavourable (0-1). To investigate the effect of lifestyle on memory stratified by APOE genotypes, participants were also grouped into people who were APOE ε4 carriers and people who were not carriers.

Outcomes

Memory function was measured at baseline and each follow-up using the World Health Organization/University of California-Los Angeles Auditory Verbal Learning Test (AVLT),27 which included measurement of immediate recall, short delay free recall (3 min later), long delay free recall (30 min later), and long delay recognition. During the test, a rater read a list of words consisting of 15 nouns; immediately after its completion, the participant attempted to repeat as many words as possible. The score of immediate recall was 0-60, and the scores of all other tests were 0-15. The standard z scores for the auditory verbal learning test were calculated based on the respective mean and standard deviation test scores. The composite z score for memory function was constructed by averaging the z scores for each test in the auditory verbal learning test.

Covariates

Potential confounders were selected based on directed acyclic graphs (supplementary figure 1) depicting the best known relations between the variables in this study. Sociodemographic information obtained at baseline were sex, place of residence (rural or urban), region (north, west, or south), marital status (married, widowed, or divorced/separated/single), years of education (<1 year, 1-6 years, 7-12 years, >12 years), monthly household income (1000-2999, 3000-4999, 5000-10 000, >10000 Chinese Yuan), occupation (manual labourer, office worker, household, or others). Health related covariates were collected at baseline and each follow-up, including age, body mass index and medical illnesses (hypertension, diabetes, hyperlipidaemia, heart attack, head injury, cerebrovascular disease, and depression). We also included the learning effect of each participant as a covariate due to repeated cognitive assessments.

Statistical analysis

Baseline characteristics of the analytical sample were summarised across three lifestyle groups as a percentage for categorical variables and mean and standard deviation for continuous variables. Missing values are summarised in supplementary table 1. A multiple imputation chain-equation was used to impute missing data. Data were assumed to be missing at random. Missing continuous variables were imputed using predictive mean matching method, and binary variables were imputed by Logistic regression model. We generated five imputed datasets with 100th iteration, and analysed each dataset separately, then combined their results by use of Rubin’s method.

Linear mixed effects models were used in this study, and all statistical assumptions were tested before interpretation of results. The data met the distributional requirements in each case. We examined the effects of different lifestyle profiles, APOE ε4 status, as well as their interactions on longitudinal memory trajectories in participants with normal cognition throughout the study by use of linear mixed effects models. The composite z score of the auditory verbal learning test was the dependent variable. The fixed effects were the following: lifestyle profiles (each respective lifestyle factor as well as the combination); APOE ε4 status; time (follow-up year from baseline); two way interactions of lifestyle with APOE ε4 status and time; and three way interactions between lifestyle, APOE ε4 status, and time. The random effects included intercept and time. Age (centred at 74 years to reduce the correlation between the age and age squared terms), age squared (to allow for the comparison of acceleration in the rate of memory decline between lifestyle groups), baseline memory score, learning effect (by assignment code to the first assessment as 1 versus subsequent assessments coded as 0), and other covariates were also adjusted in this model. In addition, the global cognitive trajectories in the cognitively normal population were evaluated using a linear mixed effects model with global cognition (standard z score of the Mini-Mental State Examination) as dependent variable. Furthermore, we investigated the interaction between lifestyle and age on memory decline.

As lifestyle status and some of the covariates changed over time, a time dependent Cox regression model (non-proportional hazard model) was used to assess the effect of lifestyle groups on progression to mild cognitive impairment or dementia in the total study population and APOE ε4 stratified population. In this model death and drop-out data were treated as censoring data. Additionally, we evaluated whether dropping out from the study affected the effects of lifestyle on mild cognitive impairment or dementia using an inverse probability weighting model. We also assessed the influence of death as a competing risk for mild cognitive impairment or dementia via competing risk analyses.

Sensitivity analyses

We conducted several additional sensitivity analyses to evaluate the robustness of our findings. Firstly, we included the number of lifestyle factors as a continuous variable in the mixed model to test the rationale of our grouping method. Secondly, we derived a weighted standardised healthy lifestyle score based on the β coefficient of each lifestyle factor in the linear mixed effects model adjusted for covariates.28 Specifically, the original binary lifestyle variables were multiplied by the β coefficients, and all the β coefficients were summed. The score of each lifestyle factor was obtained via the β coefficient of each lifestyle factor divided by the sum of the β coefficients, multiplied by 100. Participants were categorised into three groups based on the third of weighted standardised score into low, intermediate, and high score groups. Third, we excluded each lifestyle factor to identify possible factors that might drive the associations with memory. The excluded lifestyle factor was used as a confounder. Fourthly, we excluded participants who later developed mild cognitive impairment or dementia to determine whether the results were consistent with the main results. Fifthly, we excluded participants who died or dropped out throughout the study in order to evaluate the possible effects of death or drop-out on the results (if the results were consistent when participants were excluded with when they were not excluded, death or drop-out would have had no effect on the results). Finally, to assess the reverse causality of memory decline and healthy lifestyle profile, we performed a cross-lagged panel model, which is used when examining reciprocal causal processes in longitudinal data with at least two waves of data. Each analysis included a cross-wave component that estimated the change in each outcome from one wave, characterised by relationships between outcomes from each specific wave. We examined changes in composite z scores for memory in relation to changes in healthy lifestyle profiles over time.

All statistical analyses were done in R (version 3.6.3). We used the following packages: mice, for imputing; lmerTest, for linear mixed effects models; cmprsk, for competing risk models; lavaan, for cross-lagged analysis; and ipw, for inverse probability weighting. The two tailed significance level was set at P<0.05.

Patient and public involvement

Participants of the COAST study were not involved in setting the research question or the outcome measures, nor were they involved in developing plans for recruitment, design, or implementation of the study. No participants were asked for advice on interpreting or writing up of results. We know that the public involvement has great value in improving the quality of research; however, we did not have the necessary funding to invite participants for their advice. We intend to engage participants and the public to disseminate the results of our study.

Results

In total, 56 894 individuals were screened for eligibility. In phase 1, we excluded 17 148 individuals who were younger than 60 years or did not give permission to participate. In total, 39 746 individuals completed the neuropsychological assessment and clinical examination. In phase 2, we excluded 7814 individuals with mild cognitive impairment and 2860 individuals with dementia. Overall, we enrolled 29 072 with normal cognitive function who underwent APOE genotyping at baseline. During the 10 year follow-up period, 7164 individuals died and 3567 individuals discontinued participation for various reasons (fig 1).

Table 1 summarises the participants’ baseline demographic characteristics according to the three lifestyle groups. At baseline, all participants had normal cognitive function (48.54{bf0515afdcaddba073662ceb89fbb62b6b1bf123143c0e06b788e1946e8c353f} female), with a mean age of 72.23 years (standard deviation 6.61), and 20.43{bf0515afdcaddba073662ceb89fbb62b6b1bf123143c0e06b788e1946e8c353f} were carriers of APOE ε4 (supplementary table 2). Additionally, 6967 participants were enrolled in the unfavourable lifestyle group, 16 549 in the average group, and 5556 in the favourable group.

Lifestyle and memory function in older adults

We used linear mixed effects models to describe the trends in global cognition and memory function and to examine the influence of healthy lifestyle and APOE ε4 status on the annual rate of change in memory function over the 10 year follow-up period. The trajectories in the population with normal cognitive function indicated that, although the overall cognition state remained stable, memory declined continuously over time (supplementary figure 2, supplementary tables 3-4). This memory decline occurred faster in the APOE ε4 carriers than in the APOE ε4 non-carriers (0.002 points/year, 95{bf0515afdcaddba073662ceb89fbb62b6b1bf123143c0e06b788e1946e8c353f} confidence interval 0.001 to 0.003, P=0.007) (supplementary figure 2, supplementary table 5).

We evaluated the contribution of each binary lifestyle component on memory decline. The results showed that a healthy diet had the strongest effect on memory (β=0.016, 95{bf0515afdcaddba073662ceb89fbb62b6b1bf123143c0e06b788e1946e8c353f} confidence interval 0.014 to 0.017, P<0.001), followed by active cognitive activity (β=0.010, 0.008 to 0.012, P<0.001), regular physical exercise (β=0.007, 0.005 to 0.009, P<0.001), active social contact (β=0.004, 0.002 to 0.006, P<0.001), never or former smoking (β=0.004, 0.000 to 0.008, P=0.026), and never drinking (β=0.002, 0.000 to 0.004, P=0.048) (supplementary table 6). Furthermore, we analysed the association between lifestyle groups and memory performance. Our results showed that participants with favourable and average lifestyles had a slower rate of memory decline than did participants with an unfavourable lifestyle (P<0.001) (fig 2). Specifically, the decline in the composite z score was slower by 0.028 points/year (95{bf0515afdcaddba073662ceb89fbb62b6b1bf123143c0e06b788e1946e8c353f} confidence interval 0.023 to 0.032) in the favourable group and by 0.016 points/year (0.012 to 0.020) in the average group than in the unfavourable group. Figure 2 (bottom panel) shows that the mean composite Auditory Verbal Learning Test scores continuously declined over the 10 year period; the highest test scores were observed in the favourable group and the lowest in the unfavourable group.

Assessing the interaction between lifestyle and age showed a slower rate of age related memory decline in the favourable and average lifestyle groups compared with that in the unfavourable group. Compared with the unfavourable group, the memory score in the favourable lifestyle group was 0.007 (95{bf0515afdcaddba073662ceb89fbb62b6b1bf123143c0e06b788e1946e8c353f} confidence interval 0.005 to 0.009, P<0.001) points higher per increased year of age and in the average group was 0.002 (0.000 to 0.003, P=0.033) (supplementary table 7).

Lifestyle and memory function in people with or without APOE ε4

Similar results were obtained in the analyses that were stratified according to the APOE genotype (fig 3). In people who carry APOE ε4 allele and in people who do not, a favourable lifestyle was associated with better memory performance over time compared with average and unfavourable lifestyles (P<0.001). Among people who carry APOE ε4, participants with favourable and average lifestyles exhibited a slower rate of memory decline than did those with an unfavourable lifestyle (0.027 (95{bf0515afdcaddba073662ceb89fbb62b6b1bf123143c0e06b788e1946e8c353f} confidence interval 0.023 to 0.031) and 0.014 (0.010 to 0.019) points/year, respectively). Among people who did not carry the APOE ε4 allele, the estimated rates of decline were 0.029 (0.019 to 0.039) points/year slower for participants with favourable lifestyles and 0.019 (0.011 to 0.027) for participants with average lifestyles, compared with participants who had an unfavourable lifestyle. Further analysis showed no significant interaction effect between APOE ε4 status and lifestyle profiles on memory decline (P=0.52).

Lifestyle and mild cognitive impairment or dementia

Time dependent Cox regression models suggest that, over 10 years of follow-ups, a favourable lifestyle was associated with a lower probability of progression to mild cognitive impairment and dementia. Compared with an unfavourable lifestyle, the hazard ratios were 0.71 (95{bf0515afdcaddba073662ceb89fbb62b6b1bf123143c0e06b788e1946e8c353f} confidence interval 0.68 to 0.73) for an average lifestyle and 0.11 (0.10 to 0.12) for a favourable lifestyle. The result was similar when considering the competing risk of death (supplementary table 8). The inverse probability weighting model showed that participants who dropped out of the study did not affect the association between lifestyle and mild cognitive impairment or dementia (supplementary table 9). The APOE stratified analysis showed a similar result with that of the total population (supplementary table 8).

The relations between the mean auditory verbal learning test score and the percentage of participants with dementia or mild cognitive impairment are presented in figure 4. The percentage of participants with dementia or mild cognitive impairment increased as the mean Auditory Verbal Learning Test scores decreased among the older adults in our study.

Sensitivity analyses

The results of the sensitivity analyses are presented in the supplementary material. The first sensitivity analysis was conducted to test the robustness of the rationale of our grouping methods. When the number of lifestyle factors was considered as a continuous variable in the mixed effects model, two or more healthy lifestyle factors were associated with a slower rate of memory decline than did no healthy factors (supplementary table 10). The results of the analysis investigating the association between lifestyle and memory based on the weighted standardised healthy lifestyle scores showed that participants in the high and intermediate score groups had a slower rate of memory decline by 0.029 (0.025 to 0.033, P<0.001) and 0.017 (0.015 to 0.019, P<0.001) points/year, respectively, compared with participants in the low score group (supplementary tables 11-12). We found that no particular healthy lifestyle factor drove the association between lifestyle and memory (supplementary table 13). Additionally, among participants who did not develop mild cognitive impairment or dementia, did not drop out, and were alive throughout the follow-up period, the association between lifestyle profiles and memory decline remained significant (supplementary tables 14-15). Cross lagged analyses were done to assess the bidirectional, longitudinal associations between memory function and a healthy lifestyle during the 10 year follow-up period. The results supported the absence of a reverse causality between memory decline and healthy lifestyle profiles (supplementary figure 3).

Discussion

This large scale study is the first to our knowledge to estimate the effects of different lifestyle profiles, APOE ε4 status, and their interactions on longitudinal memory trajectories over a 10 year follow-up period. Our results show that a healthy lifestyle was associated with a slower rate of memory decline in cognitively normal older individuals, including in people who are genetically susceptible to memory decline.

Comparison with other studies

This study characterised the longitudinal memory trajectories of the participants with normal global cognition. Of note, the results showed that, although global cognition remained relatively stable, memory declined rapidly as the individual aged. Therefore, focusing on global cognition might lead to overlooking memory problems, especially among people older than 65 years, a third of whom are reported to experience memory complaints.29 Effective strategies for protecting against memory decline might benefit many older individuals. Previous studies have investigated the associations between lifestyle factors and memory loss; however, most have focused on a single lifestyle factor, such as smoking,30 drinking,3132 diet,33 or physical activities.734 Few studies have been conducted to target the combined effects of multiple lifestyle factors on memory decline. Thus, comparison of the contribution of each factor to memory decline has been a challenge.

In this study, we investigated the contribution of each lifestyle factor and their combined effects in a large sample size over an entire decade. We found that diet had the strongest association with memory, followed by cognitive activity, physical exercise, and social contact. Although each lifestyle factor contributed differentially to slowing memory decline, our results showed that participants who maintained more healthy lifestyle factors had a significantly slower memory decline than those with fewer healthy lifestyle factors. This information could be useful in making personal choices that can help to protect against memory decline, and our results provide further evidence that memory loss is potentially modifiable. Although the mechanisms responsible for such changes were not determined in this study, they might include reduced cerebrovascular risk, enhancement of cognitive reserve, inhibition of oxidative stress and inflammation, and promotion of neurotrophic factors.11133536

Another defining feature of our study is that all participants underwent APOE genotyping. The APOE ε4 allele is reportedly correlated with earlier and more rapidly progressive memory decline,137 and the frequency of the ε4 allele dramatically increases to 40{bf0515afdcaddba073662ceb89fbb62b6b1bf123143c0e06b788e1946e8c353f} in patients with Alzheimer’s disease.38 People who have the APOE ε4 allele are more likely to exhibit abnormally high Aβ levels in the brain and experience more rapid neurodegeneration and memory loss than people who do not.39404142 The APOE ε4 allele can also magnify the effects of other risk factors, including physical inactivity, unhealthy diet, and smoking.43 However, most studies that have explored the role of APOE have focused on the associations between lifestyle and global cognition rather than memory.444546 Here, we observed a positive effect of a healthy lifestyle on memory in both carriers of APOE ε4 and non-carriers, and no interaction effect was observed between the APOE genotype and lifestyle profiles over time. These results provide an optimistic outlook, as they suggest that although genetic risk is not modifiable, a combination of more healthy lifestyle factors are associated with a slower rate of memory decline, regardless of the genetic risk.

Strengths and limitations of this study

Although many studies have investigated the relationship between a healthy lifestyle and dementia, few have focused on memory loss, which is a condition that older adults with normal cognitive function can experience and that differs from dementia. This multicentre study with a large sample and a long term follow-up period provided an opportunity to observe the longitudinal trajectories of memory function in older adults with different lifestyles. However, our study also has some limitations. Firstly, the assessments of lifestyle factors were based on self-reports and are, therefore, prone to measurement errors. Secondly, several participants were excluded due to missing data or not returning for follow-up evaluations, which might have led to selection bias. Thirdly, the proportion of individuals with an unhealthy lifestyle might have been underestimated in our study because people with poor health were less likely to have participated in the study. Fourthly, given the nature of our study design, we could not assess whether maintaining a healthy lifestyle had already started influencing memory by the time of enrolment in the study. Fifthly, we evaluated memory using a single neuropsychological test that does not comprehensively reflect overall memory function. However, the Auditory Verbal Learning Test is an effective instrument for memory assessment, and we used a composite score based on four Auditory Verbal Learning Test subscales to represent memory conditions to the greatest extent possible. Sixthly, as participants might become familiar with repeated cognitive testing, a learning effect could have influenced the results, although, we considered that possibility in the design of the statistical analysis method. Finally, we studied memory decline solely among older adults; however, memory problems commonly affect young individuals as well. Thus, further studies should be conducted to facilitate a more extensive investigation into the effects of a healthy lifestyle on memory decline across the lifespan. This approach would help to elucidate the crucial age window during which a healthy lifestyle can exert the most favourable effect.

Conclusions

The results of this study provide strong evidence that adherence to a healthy lifestyle with a combination of positive behaviours, such as never or former smoking, never drinking, a healthy diet, regular physical exercise, and active cognitive activity and social contact, is associated with a slower rate of memory decline. Importantly, our study provides evidence that these effects also include individuals with the APOE ε4 allele. This study might offer important information to protect older adults against memory decline.

What is already known on this topic

  • Memory is a fundamental function of daily life that continuously declines with increasing age

  • Evidence from cohort studies is insufficient to evaluate the effect of healthy lifestyle on memory trajectory

  • Given the multifactorial biological cause of memory decline, a combination of healthy lifestyle factors might be necessary for an optimal effect, even for people who are genetically susceptible to memory decline

What this study adds

  • A combination of positive healthy behaviours is associated with a slower rate of memory decline in cognitively normal older adults, including in people with the apolipoprotein E ε4 allele

  • These results might offer important information for public health initiatives to protect older adults against memory decline

Six Healthy Lifestyle Habits Linked to Slowed Memory Decline

Adhering to 6 balanced lifestyle behaviors is joined to slower memory drop in more mature older people, a significant, population-based mostly review indicates.

Investigators located that a wholesome diet, cognitive activity, standard physical training, not smoking cigarettes, and abstaining from liquor ended up significantly connected to slowed cognitive decline irrespective of APOE4 status.

Following changing for overall health and socioeconomic aspects, investigators identified that every single personal healthier conduct was affiliated with a slower-than-common drop in memory over a decade. A healthy diet plan emerged as the strongest deterrent, adopted by cognitive exercise and physical workout.

“A healthy lifestyle is related with slower memory decline, even in the presence of the APOE4 allele,” research investigators led by Jianping Jia, MD, PhD, of the Innovation Middle for Neurological Ailments and the Department of Neurology, Xuan Wu Healthcare facility, Money Professional medical University, Beijing, China, publish.

“This study may well provide essential information to shield more mature grownups against memory decline,” they add.

The examine was posted on the web January 25 in The BMJ.

Protecting against Memory Decline

Memory “constantly declines as people age,” but age-associated memory decrease is not essentially a prodrome of dementia and can “simply be senescent forgetfulness,” the investigators notice. This can be “reversed or [can] turn into stable,” instead of progressing to a pathologic state.

Factors affecting memory include things like growing old, APOE4 genotype, continual conditions, and life style patterns, with lifestyle “receiving rising focus as a modifiable habits.”

Nevertheless, couple studies have focused on the impression of lifestyle on memory and those people that have are primarily cross-sectional and also “did not think about the conversation involving a nutritious life style and genetic hazard,” the researchers note.

To look into, the scientists executed a longitudinal research, known as the China Cognition and Ageing Research, that deemed genetic possibility as perfectly as life style aspects.

The research began in 2009 and concluded in 2019. Participants have been evaluated and underwent neuropsychological screening in 2012, 2014, 2016, and at the study’s conclusion.

Members (n = 29,072 indicate [SD] age, 72.23 [6.61] several years 48.54{bf0515afdcaddba073662ceb89fbb62b6b1bf123143c0e06b788e1946e8c353f} gals 20.43{bf0515afdcaddba073662ceb89fbb62b6b1bf123143c0e06b788e1946e8c353f} APOE4 carriers) had been expected to have regular cognitive purpose at baseline. Info on individuals whose ailment progressed to mild cognitive impairment (MCI) or dementia during the follow-up time period have been excluded following their diagnosis.

The Mini–Mental Condition Assessment was employed to assess world-wide cognitive purpose. Memory operate was assessed working with the Entire world Wellness Group/University of California–Los Angeles Auditory Verbal Discovering Test.

“Way of life” consisted of six modifiable components:

  • Bodily workout (weekly frequency and complete time)

  • Using tobacco (current, former, or by no means-smokers)

  • Liquor consumption (by no means drank, drank often, minimal to excessive drinking, and weighty ingesting)

  • Diet regime (every day intake of 12 food goods: fruits, greens, fish, meat, dairy products, salt, oil, eggs, cereals, legumes, nuts, tea)

  • Cognitive exercise (composing, examining, actively playing cards, mahjong, other game titles)

  • Social contact (collaborating in conferences, attending functions, browsing good friends/kinfolk, traveling, chatting on the net)

Participants’ lifestyle was scored on the basis of the variety of healthy factors they engaged in.

Life-style Variety of wholesome aspects Amount of individuals
Favorable 4 – 6 5556
Common 2 – 3 16,549
Unfavorable 1 – 2 6967

 

Members ended up also stratified by APOE genotype into APOE4 carriers and noncarriers.

Demographic and other objects of wellness information, together with the presence of health care health issues, were utilized as covariates. The researchers also integrated the “learning result of every participant as a covariate, owing to recurring cognitive assessments.”

Vital for General public Wellness

All through the 10-year period, 7164 individuals died, and 3567 stopped collaborating.

Contributors in the favorable and ordinary teams showed slower memory drop for each elevated calendar year of age (.007 [0.005 – 0.009], P < .001 and 0.002 [0 .000 – 0.003], P = .033 points higher, respectively), compared to those in the unfavorable group.

Healthy diet had the strongest protective effect on memory.

Lifestyle factor β (95{bf0515afdcaddba073662ceb89fbb62b6b1bf123143c0e06b788e1946e8c353f} CI) P value
Healthy diet 0.016 (.014 – 0.017) < .001
Active cognitive activity 0.010 (.008 – 0.012) < .001
Regular physical exercise 0.007 (.005 – 0.009) < .001
Active social contact 0.004 (.002 – 0.006) < .001
Never/former smoking 0.004 (.000 – 0.008) = .026
Never drinking 0.002 (0.000 – 0.004) = .048

Memory decline occurred faster in APOE4 vs non-APOE4 carriers (0.002 points/year [95{bf0515afdcaddba073662ceb89fbb62b6b1bf123143c0e06b788e1946e8c353f} CI, 0.001 – 0.003] P = .007).

But APOE4 carriers with favorable and average lifestyles showed slower memory decline (0.027 [0.023 – 0.031] and 0.014 [0.010 – 0.019], respectively), compared to those with unfavorable lifestyles. Similar findings were obtained in non-APOE4 carriers.

Those with favorable or average lifestyle were respectively almost 90{bf0515afdcaddba073662ceb89fbb62b6b1bf123143c0e06b788e1946e8c353f} and 30{bf0515afdcaddba073662ceb89fbb62b6b1bf123143c0e06b788e1946e8c353f} less likely to develop dementia or MCI, compared to those with an unfavorable lifestyle.

The authors acknowledge the study’s limitations, including its observational design and the potential for measurement errors, owing to self-reporting of lifestyle factors. Additionally, some participants did not return for follow-up evaluations, leading to potential selection bias.

Nevertheless, the findings “might offer important information for public health to protect older against memory decline,” they note — especially since the study “provides evidence that these effects also include individuals with the APOE4 allele.”

“Important, Encouraging” Research

Commenting for Medscape Medical News, Severine Sabia, PhD, a senior researcher at the Université Paris Cité, INSERM Institut National de la Santé et de la Recherche Medicalé, France, called the findings “important and encouraging.”

However, said Sabia, who was not involved with the study, “there remain important research questions that need to be investigated in order to identify key behaviors, which combination, the cutoff of risk, and when to intervene.”

Future research on prevention “should examine a wider range of possible risk factors” and should also “identify specific exposures associated with the greatest risk, while also considering the risk threshold and age at exposure for each one.”

In an accompanying editorial, Sabia and co-author Archana Singh-Manoux, PhD, note that the risk of cognitive decline and dementia are probably determined by multiple factors.

They liken it to the “multifactorial risk paradigm introduced by the Framingham study,” which has “led to a substantial reduction in cardiovascular disease.” A similar approach could be used with dementia prevention, they suggest.

The study was funded by the Key Project of the National Natural Science Foundation of China the National Key Scientific Instrument and Equipment Development Project the Key Project of the National Natural Science Foundation of China the Beijing Scholars Program the Beijing Brain Initiative from the Beijing Municipal Science and Technology Commission the CHINACANADA Joint Initiative on Alzheimer’s Disease and Related Disorders the Mission Program of Beijing Municipal Administration of Hospitals National Natural Science Foundation of China the National Science and Technology Foundation of China the Beijing Natural Science Foundation Major Project of Beijing Municipal Science and Technology Commission and the Sailing Plan of Beijing Municipal Administration of Hospitals.

The other authors have disclosed no relevant financial relationships. Sabia received grant funding from the French National Research Agency.

A heat and cheery vibe welcomes the two students and neighborhood people who can lounge on comfortable sofas or operate and analyze at tables. Final fall, even right before the cafe officially reopened, it turned property to the broadcast of The Jaguar Football Show with Mentor Eric Dooley.

Longtime Southern Cofe supporters will observe the addition of a new, separate place inside the place, the place patrons can now document podcasts and keep conferences or research classes. It is another way the location can serve as a community hub, Isadore claims.

The menu capabilities a variety of hot and chilly espresso and brewed coffee beverages. Juices, balanced bowls and smoothies are also a huge section of the line-up in this article, like pressed fresh fruit and vegetable juices as effectively as many distinctive combos of fruit and vegetable smoothies. The Lacumba Mint, named for Southern’s mascot, combines cucumber, eco-friendly apple, mint, avocado, honey and a decision of milk, while the Backyard in a Cup is manufactured with milk, spinach, kale, banana and pineapple. Isadore suggests he hopes to add a salad bar soon.

Isadore suggests it wasn’t his initial intention to mix coffee beverages with plant-dependent choices, but when he initially opened in this article in 2017, customers questioned for it.

“Having a much healthier menu was a request we listened to straight from the group, from our earliest buyers,” Isadore claims. “The narrative for who we have been altered at that minute. At times the people today ascertain what you are likely to be.”

A new individual space accommodates podcasts or group meetings.

Whilst Southern Cofe’s Main Street Market place booth has helped develop recognition among downtown personnel and Red Stick Farmers Market shoppers, its Scotlandville spot fulfills Isadore’s desire to be a collecting location for Southern pupils and neighbors. Isadore, who attended Southern in the late 90s, states one of his initial enterprise desires was to put a coffee store in each HBCU in the country.

That dream was partly fulfilled when the Southern University Legislation Middle became household to Isadore’s to start with coffee notion, Property of Java, which operated from 2010 to 2017. It closed when Southern commenced outsourcing foodstuff and beverage functions to countrywide caterer Aramark, he claims.

Residence of Java, Isadore’s initial espresso shop, was once found in the Southern University Legislation Centre.

Isadore preferred to stay in the surrounding Scotlandville local community, so he opened Property of Java briefly in one more location. But that shut immediately after matters went south with Isadore’s company companion, he states. Finally, he identified the storefront on Scotland Avenue, a previous grocery retail store, which he renovated himself at evening immediately after doing work full time during the day. The place would grow to be the to start with locale for his recently named Southern Grind Cofe in 2017, a identify that he afterwards shortened to Southern Cofe. “Cofe” is a Isadore’s personal time period, fusing espresso and café, he suggests.

These 4 Healthy Eating Patterns May Led to a Longer Life, Study Finds

Your nutritional sample may well assistance predict how extensive you live. This is the conclusion from a new research released in The Journal of the American Clinical Affiliation evaluating eating plan good quality and mortality. The examine uncovered that persons that consumed a a lot more nutrient-dense diet program had been fewer most likely to die early.

The feeding on behavior of 119,315 folks (75,230 girls and 44,085 adult men) from the Nurses’ Health Study and the Wellbeing Industry experts Stick to-Up Examine had been assessed more than 36 decades. In the course of that time body, they evaluated adherence and results related to four distinctive nutritional designs, all of which adhere in some capability to the United States Dietary Tips for Americans.

The four having patterns analyzed ended up:

  • The Wholesome Consuming Index 2015 (HEI), which measures diet excellent and adherence and makes use of guidelines from the Dietary Tips for Americans in its scoring assessment.
  • The Alternate Healthy Consuming Index (AHEI), which was designed by scientists at the Harvard T.H. Chan School of Community Health as an choice to the unique HEI. Like the HEI, it provides scoring but focuses more on minimizing serious sickness danger.
  • The Alternate Mediterranean Diet program (AMED), which measures adaptation to the Mediterranean diet plan principles.
  • The Healthful Plant-based Food plan Index (HPDI), which measures adherence to a healthier plant-dependent diet plan.

The examine found there are various ways to adhere to a nutritious diet regime

Folks with the best adherence to at least 1 of the much healthier ingesting indexes experienced the most affordable threat of death in contrast with people with the most affordable adherence. This outcome was found among all 4 balanced feeding on indexes. Additionally, this end result was consistent among multiple racial and ethnic groups. It was also noticed in a dose-dependent manner (the better the rating, the reduced the risk for early loss of life from cardiovascular disease, respiratory disorder, and cancer). Higher adherence scores for AMED and AHEI were being even further linked with a lessen risk of neurodegenerative illness mortality.

There were being quite a few critical takeaways from the research. Very first, it emphasised that there are various means to adhere to a much healthier way of having. Considering the fact that there is no “one size fits all” food plan, it demonstrated that distinct nutritional designs could be tailored to any ethnic or own desire. Next, there were many similarities concerning the four ingesting patterns. For case in point, all eating practices were being nutrient-dense, providing considerable natural vitamins and minerals. They were also far more slanted to far more plant-dependent techniques. Dr. Frank Hu, chair of office of nourishment and epidemiology at Harvard T.H. Chan Faculty of Public Overall health, was the study’s lead creator. He tells Currently.com, “Despite the fact that these diet programs differ in some facets, they all include high quantities of healthy plant food items these as fruits, vegetables, full grains, nuts, and legumes, and reduced amounts of refined grains, added sugars, sodium, and purple and processed meats.”

For a for a longer period everyday living, target on these 5 dietary behavior:

1. Focus on fiber

Just one of the finest methods to consume additional crops is to concentrate on receiving much more fiber. A 2019 systematic critique and meta-assessment in the journal Lancet found that ample fiber ingestion (amongst 25g to 29g for every day) was also linked with a reduction in danger of all will cause and decreases in heart disorder, Sort 2 diabetic issues, and colorectal cancer.

2. Nosh on nuts

Nut use was emphasized in all four eating patterns in the examine. Nuts are substantial in wholesome fat, which may help maximize satiety and fullness, a essential part of excess weight management. They have also been connected with greater mind overall health and could lower the danger of coronary heart condition.

3. Get colorful

Coloration is important in the plant entire world and will come from compounds known as phytonutrients that give both of those hue and benefit to the plant. Studies demonstrate that consuming colorful fruits and vegetables can also direct to a lengthier existence.

4. Opt for plant and marine sources of protein

Beans, legumes and fish had been highlighted in several of the eating styles. The AMED sample, for illustration, encouraged the usage of fatty fish, like salmon, that can supply plentiful quantities of omega-3 fatty acids. In distinction, beans and legumes present fiber in addition to protein.

5. Find flexibility

The analyze shown that healthful taking in can be personalized to the particular person — and that pursuing various methods within just the popular themes could guide to important health advantages. “In get for a person to adhere to a nutritious diet program very long-phrase, 1 demands to enjoy it. So it is significant for people today to adapt these balanced ingesting styles to their personal food stuff and cultural choices. Also, 1 does not want to adhere to only just one dietary approach for their total daily life. To boost wide variety and adherence, one particular can switch between these a variety of wholesome diets or produce their individual flexitarian food plan. Even so, the core healthy taking in principles should continue being the very same: Try to eat far more minimally-processed plant foods these types of as fruits, veggies, nuts, whole grains, and legumes take in less purple meat and ultra-processed foods substantial in sugar, sodium, and refined starch,” Hu points out.

If overhauling your nutritional sample would seem overpowering, take into account this — toddler ways will go even more than no movement at all. Hu claims that many nutritious dietary patterns have been linked with, not only a for a longer time life, but a reduction in persistent condition danger complications as perfectly. Hu points out that, for case in point, “a bigger adherence to the Mediterranean diet plan lowers the chance of cardiovascular issues among individuals with diabetic issues.” Also, balanced consuming designs have been affiliated with much better survival amongst men and women with breast or colorectal most cancers.”

As Hu claims, “it’s never ever way too late to undertake a healthier diet program.”
