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.

Abstract Background We aimed to examine the effect of physical activity on different cognitive domains among patients with diabetes. Methods We used two waves of data from the Chinese Health and Retirement Longitudinal Study (CHARLS, 2013–2015), a nationally representative dataset of Chinese population aged over 45. Total physical activity scores were calculated based on the International Physical Activity Questionnaire (IPAQ). Executive function and episodic memory were used as measures of cognitive function. We conducted lagged dependent variable models to explore the association between physical activity and cognitive function in full sample as well as two different age groups (45–65, ≥65). Results: 862 diabetic patients were included. We found that diabetic participants who had greater level of physical activity at baseline were associated with better episodic memory function in 2 years (p < 0.05). Moreover, physical activity was significantly associated with less decline in episodic memory in fully adjusted models, and the associations were stronger among patients aged 45–65 years (p < 0.05). No statistically significant association was found between physical activity and executive function in all age groups. Conclusions Physical activity may prevent some of the potential decline in episodic memory in diabetic patients. Clinicians and public health departments should strengthen the promotion of physical activity and develop early screening tools among diabetic participants to prevent the progression of cognitive impairment.

Background: Several kinds of motor dysfunction can predict future cognitive impairment in elderly individuals. However, the ability of the fine motor index (FINEA) and gross motor index (GROSSA) to predict the risk of cognitive impairment has not been assessed. Objective: We investigated the associations between FINEA/GROSSA and cognitive impairment. Methods: The data of 4,745 participants from The Irish Longitudinal Study on Ageing (TILDA) were analyzed. Cognitive function was assessed using the Mini-Mental State Examination (MMSE). We first assessed the correlation between the FINEA GROSSA and MMSE in a cross-sectional study. Then, we further investigated the predictive role of the incidence of cognitive impairment in a prospective cohort study. Results: We found that both FINEA and GROSSA were negatively correlated with MMSE in both the unadjusted (FINEA: B = –1.00, 95%confidence intervals (CI): –1.17, –0.83, t = –11.53, p <  0.001; GROSSA: B = –0.85, 95%CI: –0.94, –0.76, t = –18.29, p <  0.001) and adjusted (FINEA: B = –0.63, 95%CI: –0.79, –0.47, t = –7.77, p <  0.001; GROSSA: B = –0.57, 95%CI: –0.66, –0.48, t = –12.61, p <  0.001) analyses in a cross-sectional study. In a prospective cohort study, both high FINEA and high GROSSA were associated with an increased incidence of cognitive function impairment (FINEA: adjusted odds ratios (OR) = 2.35, 95%CI: 1.05, 5.23, p = 0.036; GROSSA adjusted OR = 3.00, 95%CI: 1.49, 6.03, p = 0.002) after 2 years of follow-up. Conclusion: Higher FINEA and GROSSA scores were both associated with an increased incidence of cognitive impairment. FINEA or GROSSA might be a simple tool for identifying patients with cognitive impairment.

Lifestyle behaviors such as exercise, diet, smoking, and alcohol consumption can profoundly affect long-term health outcomes like cardiovascular disease, diabetes, and cancer as well as acute and long-term cognitive function. for those in leadership roles, stamina, a baseline level of good health, and optimal cognitive function are important for leadership performance and sustainability. The purpose of this study is to describe various biometric markers and lifestyle behaviors of senior level executives and the implications for health, leadership, and brain function. Data were collected from male (n = 2925) and female (n = 574) executives who attended the Leadership at the Peak (LaP) course at the Center for Creative Leadership (CCL) between November 2007 and July 2018  fifty-two percent of male participants and 48% of female participants were maintenance exercisers. only 2.2% of males and 0.7% of females were current smokers. average servings of alcohol per week were 5.6 and 4.5 for males and females, respectively. However, 23% of executives reported drinking little to no alcohol. The average number of hours of sleep per week was 6.6 hours for both male and female executives. On average, executives were slightly overweight with an average body fat percentage of 22.6% for males and 30.1% for females and an average waist circumference of 82.7 cm and 97.5 cm for males and females, respectively. Non-high-density lipoprotein levels were above ideal at 138.3 mg/dL for males and 125.2 mg/dL for females. Daily servings of fruit and vegetable consumption was less than ideal, averaging 4.7 servings a day for females and 3.7 servings for males. Overall, senior executives are healthier than the average american; however, given that their jobs are cognitively demanding, strategies such as eating more nutrient-rich plant foods and getting adequatesleep and regular exercise are increasingly important.

Introduction: Hypertension is associated with increased risk for cognitive decline. Lifestyle behaviors such as moderate physical activity (MPA) and adequate sleep duration may mitigate this decline, though limited research exists. The aim of the study was to examine the joint association of MPA and sleep duration on cognitive function by hypertension status. Methods: Adults (n=2976, ≥60yrs) from the 2011-2014 National Health and Nutrition Examination Survey (NHANES) were assessed for their habitual sleep duration (<7, 7-8.9, ≥9hr) , self-reported participation in regular MPA (yes/no), reported physician-diagnosed hypertension (yes/no), and cognitive function (Digit Symbol Substitution Test [DSST]; Animal Fluency test). Weighted linear regression analyses were conducted to assess joint association of sleep duration and MPA on cognitive function, and test the modifying effect of hypertension status (alpha level set at 0.1) after adjustment for demographics. Results: See Table. There were significant main effects for combined MPA and sleep duration on DSST (Wald F (5,28)=5.33, p =.001) and Animal Fluency (Wald F (5,28)=2.58, p =.05). Participants who did not engage in MPA regardless of sleep duration had significantly worse cognitive function compared to participants who engaged in MPA and obtained 7-8.9hr sleep. There was a significant interaction between MPA-sleep duration groups and hypertension status on DSST (Wald F (5,28)=2.42, p =.06), but not on Animal Fluency. Stratified analyses indicated among individuals with hypertension the buffering effect of MPA regardless of sleep duration was maintained, but not for individuals without hypertension. Conclusions: In a sample of adults, regular MPA predicted better cognitive outcomes regardless of sleep duration. Among individuals with hypertension regular MPA regardless of sleep duration was significantly associated with better executive function, but no such association was found among individuals without hypertension.
