This study examined the regional and geographical disparities in body mass index (BMI) among Chinese older adults. Using panel data from the Chinese Longitudinal Healthy Longevity Survey, participants included 3,740 older adults (age ≥ 65 years) who answered all three waves of the survey (2009–2014). Sex-stratified and multistate Cox regression was used to examine the disparities in BMI change. Results showed that both older males and older females who resided in the central-south had lower rates of weight change from nonobese to obese, compared with those from the east. Older females from urban regions had higher rate of weight change from nonobese to obese, compared with rural participants (hazard ratio [HR]: 1.35, 95% confidence interval [CI] = [1.13, 1.60]; p < .01). However, there were no disparities between urban and rural areas among older males ( p > .05). These results provided practical implications for regional and geographical disparities in BMI among Chinese older adults.

Abstract Background Socio-demographic transitions have dramatically changed the traditional family care settings in China, caused unmet care needs among older adults. However, whether different primary caregiver types have different influences on disabled older adults’ health outcomes remain poorly understood. We aimed to examine the association between the type of primary caregiver (e.g., spouse and children) and death among community-dwelling Chinese older adults disabled in activities of daily living. Methods We used data from Chinese Longitudinal Healthy Longevity Survey. The analytic sample comprised 4278 eligible adults aged ≥ 80 years. We classified primary caregiver type into five categories: spouse, son/daughter-in-law, daughter/son-in-law, grandchildren, and domestic helper. We used Cox regression model to examine the association between primary caregiver type and all-cause mortality. Covariates included age, sex, residence, years of education, co-residence status, financial independence, whether living with children, number of ADL disability, number of chronic conditions, and self-reported health, cognitive impairment, and caregiving quality. Results Married older adults whose primary caregivers were son/daughter-in-law had a 38% higher hazard of death than those who had spouse as the primary caregiver. Married men who received care primarily from son/daughter-in-law or daughter/son-in-law had a 64 and 68% higher hazard of death, respectively, than those whose primary caregiver was spouse. The association between primary caregiver type and mortality among widowed older adults differed between urban and rural areas. Urban residents who had domestic helpers as the primary caregiver had an 16% lower hazard of death, while those living in rural areas had a 50% higher hazard of death, than those having son/daughter-in-law as the primary caregiver. Conclusions The quality of care of the primary caregiver may be a risk factor for mortality of disabled older adults in China. Interventions are necessary for reducing unmet needs and managing care burden.

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 Background: The effect of physical work on the risk of cognitive impairment in Chinese older adults living in rural areas remains to be elucidated. We investigated whether physical work and exercise can reduce the risk of cognitive impairment. Methods: We collected data from 7,000 individuals without cognitive impairment (age ≥60 years) over a follow-up period of 2 years. The Chinese version of the Mini-Mental State Examination was used to assess cognitive function, and the multivariable Cox regression model was used to identify associations between physical work/exercise and cognitive impairment. Results: Over a median follow-up period of 1.93 years, 1,224 (17.5%) of 7,000 participants developed cognitive impairment, with a total incidence of 97.69 per 1,000 person-years. Participation in physical work (hazard ratio [HR]: 0.66; 95% confidence interval [CI], 0.55-0.78) or exercise (HR: 0.76; 95% CI, 0.62-0.93) was associated with a reduced risk of cognitive impairment. Agricultural work (HR: 0.60; 95% CI, 0.49-0.73) and walking/tai chi (HR: 0.75; 95% CI, 0.60-0.93) exerted significant protective effects against cognitive impairment. Conclusions: Physical work and exercise can reduce the risk of cognitive impairment in older adults. Reasonable types and appropriate intensities of physical activity are recommended to prevent or delay the progression of cognitive impairment.
