Rate Of Decline

Introduction: With global population aging, identifying public health strategies to prevent or reduce cognitive decline is of increasing importance. This study explores the potential role of a modifiable dietary behavior, fish consumption, to reduce the rate of cognitive decline in a cohort of Chinese older adults. Methods: This study comprised adults aged ≥55 who completed a brief cognitive screening test at two or more waves of the China Health and Nutrition Survey (CHNS) from 1997 to 2004. The cognitive screening test had a maximum of 31 points and assessed immediate and delayed memory, attention, calculation, and orientation. Diet was measured by 3-day 24-hour recalls. Multivariable-adjusted linear mixed-effects models were used to evaluate the relation of fish intake at baseline with changes in cognitive scores, adjusting for age, gender, region, urbanization index, education, household income, energy intake, physical activity, current alcohol use, current smoking, and consumption of fresh vegetables, fruits, fresh legumes, and high-fat meat, as well as time, and time interactions with each covariate. Based on the distribution of fish intake, we compared consumption ≥1 vs. <1 serving/week. Sensitivity analysis included 1) removing shellfish and/or preserved fish; 2) exploring potential confounding by or interactions with hypertension or body mass index; 3) excluding those with the lowest 10% baseline cognitive scores; 4) adjusting for dietary patterns to determine if associations were independent of overall eating patterns; 5) using propensity score analysis to ensure comparability of the fish intake groups. Results: The average follow-up among 1566 older adults was 5.3 years, with a mean annual rate of decline 0.40 points. Since age significantly modified the fish-cognitive change association (p=0.003), we stratified analysis by adults <65 (n=968) at first measure, and ≥65 (n=598). No significant associations were found among adults <65. Among adults ≥65, compared with persons who consumed fish <1 serving/week, the average rate of global cognitive decline was reduced by 0.35 points per year or 55% (p = 0.001) among those consuming fish ≥1 serving/week. Results remained consistent in sensitivity analysis. When the cognitive test items were analyzed based on the domain assessed, fish intake was associated with a significantly slower rate of decline in memory scores among adults ≥65. The average rate of memory decline was reduced by 60% among persons who consumed fish ≥1 serving/week. Conclusions: Fish intake of at least 1 serving per week predicted a slower rate of cognitive decline among Chinese adults ≥65 years old, particularly for immediate and delayed memory. The cognitive benefits of fish intake were not apparent among Chinese adults aged 55 to 64. This is the first study in Chinese older adults to evaluate the role of fish consumption on cognitive decline.

Abstract Background Social isolation and loneliness have each been associated with cognitive decline, but most previous research is limited to Western populations. This study examined the relationships of social isolation and loneliness on cognitive function among Chinese older adults. Methods This study used two waves of data (2011 and 2015) from the China Health and Retirement Longitudinal Study and analyses were restricted to those respondents aged 50 and older. Social isolation, loneliness, and cognitive function were measured at baseline. Follow-up measures on cognitive function were obtained for 7761 participants (mean age = 60.97, s.d. = 7.31; male, 50.8%). Lagged dependent variable models adjusted for confounding factors were used to evaluate the association between baseline isolation, loneliness, and cognitive function at follow-up. Results Loneliness was significantly associated with the cognitive decline at follow-up (episodic memory: β = −0.03, p < 0.01; mental status: β = −0.03, p < 0.01) in the partially adjusted models. These associations became insignificant after additional confounding variables (chronic diseases, health behaviors, disabilities, and depressive symptoms) were taken into account (all p > 0.05). By contrast, social isolation was significantly associated with decreases in all cognitive function measures at follow-up (episodic memory: β = −0.05, p < 0.001; mental status: β = −0.03, p < 0.01) even after controlling for loneliness and all confounding variables. Conclusions Social isolation is associated with cognitive decline in Chinese older adults, and the relationships are independent of loneliness. These findings expand our knowledge about the links between social relationships and the cognitive function in non-Western populations.

Bidirectional Association

This study investigated the bidirectional association between physical and cognitive function in later life and examined the mechanisms underlying the interrelationship. We employed cross-lagged panel models to analyze a sample of 4232 unique participants aged 65 years and older from three waves of the Chinese Longitudinal Healthy Longevity Survey. Physical activity and social participation were tested as potential mediators between physical and cognitive function. Our findings revealed a reciprocal relationship between physical and cognitive function and a reciprocal relationship between physical and cognitive decline. Moreover, physical activity was confirmed to mediate the bidirectional association between physical and cognitive function, whereas social participation did not seem to be a mediator. A vicious cycle linking physical and cognitive decline may exist in Chinese older adults. However, leading a physically active lifestyle could be an effective intervention to slow physical and cognitive aging, thereby toning down the vicious cycle.

Introduction: The interactions between apolipoprotein E (APOE) genotype and diet pattern changes were found significant in several trials, implying that APOE gene may modify the effect of animal protein-rich food on health outcomes. We aim to study the interaction of APOE genotype with the effect of meat, fish and egg intake on mortality.Methods: This population-based study enrolled 8,506 older adults (mean age: 81.7 years, 52.3% female) from the Chinese Longitudinal Healthy Longevity Study. The intake frequency of meat, fish and egg was assessed by 3-point questions at baseline. Cox regression was conducted to calculate the hazard ratios for all-cause mortality of intake levels of meat, fish and egg. The analyses were stratified by APOE genotype and sex. The analyses were performed in 2020.Results: In the multivariable-adjusted models, meat and fish intake was associated with all-cause mortality (high vs. low intake: meat: HR: 1.14, 95% CI: 1.01, 1.28; fish: HR: 0.83, 95% CI: 0.73, 0.95). APOE genotype have significant interactions with meat and fish intake (Ps &lt; 0.05). Compared with low fish intake, high fish intake was associated with lower risk of mortality (HR: 0.74, 95% CI: 0.56–0.98) only among the APOE ε4 carriers. High meat intake was significantly associated with higher risks of mortality (HR: 1.13, 95% CI: 1.04–1.25) only among the APOE ε4 non-carriers. The interactive relationship was restricted among the male. No significant findings were observed between egg and mortality among carriers or non-carriers.Conclusions: Among Chinese older adults, the significance of associations of mortality with reported meat or fish intake depended on APOE-E4 carriage status. If validated by other studies, our findings provide evidence for gene-based “precision” lifestyle recommendations.

Abstract Body composition has been proposed as an important modifiable risk factor of cognitive decline in multiple epidemiological studies. However, the relationship between body mass index (BMI) and cognitive function remains controversial and conflicting in diverse populations. This study aims to investigate the association between BMI and cognitive decline in U.S. Chinese older adults. Classifications of BMI are based on Asian criteria recommended by WHO (underweight: BMI&lt;18.5, normal weight: 18.5≤BMI&lt;23, overweight: 23≤bmi&lt;27.5, obesity: bmi≥27.5). Logistic regression models were conducted. Compared with normal-weight participants, underweight participants were more likely to experience decline in episodic memory (OR=1.68, p=0.002) and work memory (OR=1.38, p=0.05). Being overweight and obesity were not associated with cognitive function decline. The findings indicate that underweight could potentially be a risk factor of cognitive function decline among U.S. Chinese older adults. Perspective studies may further investigate the association between weight loss and cognitive decline for the development of prevention strategies.

Abstract Too little or too much sleep is associated with accelerated cognitive decline in older adults. However, sleep duration does not capture other sleep problems prevalent in older adults, such as difficulties with falling or staying asleep. Less is known about the impact of sleep quality on cognitive ageing, and if this relationship differs between England and China. Therefore, the aim of this study is to examine the relationship of self-reported sleep quality with cognitive performance and rate of change over 6-7 years follow-up in two nationally-representative samples of English and Chinese older adults. The primary outcome was a memory score (range 0-20), which was assessed using immediate and delayed 10-word recall tests in both cohorts. The results of bivariate descriptive analyses at baseline suggest there may be an inverted U-shaped association between sleep quality and memory in English older adults, and a positive dose-response association in Chinese older adults.
