“…Third, the present study revealed physical function decline had a negative effect on cognitive function. This result is in line with those reported by past studies, which suggested greater physical function can buffer cognitive impairment (Grande et al, 2014;Vancampfort et al, 2017Vancampfort et al, , 2018. Changes in physical and cognitive function are common among older individuals, and the causal mechanism between the two variables is debated widely.…”

“…Physical function is basic physical ability for activity and includes basic activities of daily living and instrumental activities of daily living (IADL) such as shopping, handling money, and transportation utilization (Bidzan et al, 2016;Bae et al, 2019). Actually, past studies verified the relevance between physical function and cognitive function (Grande et al, 2014;Vancampfort et al, 2017Vancampfort et al, , 2018. Inversely, decreased physical function was positively related to cognitive impairment.…”

PurposeThis study aimed to examine the long-term association between social activity, physical function decline and cognitive function, as well as verify the long-term mediating effect of physical function decline on the relationship between social activity and cognitive function.MethodsData from the Korean Longitudinal Study of Aging (KLoSA) that was collected over 10 years was analyzed. The sample included 10,240 adults aged 45–93 years (Mean age = 61.66 [SD = 11.061]). Multivariate latent growth modeling (LGM) was applied to verify the long-term effect of social activity and physical function on cognitive function.ResultsThe results revealed that social activity had a positive impact on cognitive function and negative impact on physical function decline after controlling for age and education level. Additionally, physical function decline negatively influenced cognitive function. Finally, social activity indirectly affected cognitive function through physical function decline.ConclusionThe contribution of this study was to test the long-term effect social activity on physical and cognitive function.

Objectives A number of small‐scale, single‐country studies have suggested that muscular weakness may be a biomarker for cognitive health, mild cognitive impairment (MCI), and dementia. However, multinational, representative studies are lacking, particularly from low‐ and middle‐income countries (LMICs). Thus, we assessed the association between muscular strength (measured by maximal handgrip) and MCI in six LMICs (China, Ghana, India, Mexico, Russia, and South Africa), using nationally representative data. Methods Cross‐sectional, community‐based data on individuals aged 50 years or older from the World Health Organization's Study on Global Ageing and Adult Health were analyzed. MCI was defined according to the National Institute on Aging‐Alzheimer's Association criteria. Weak handgrip strength was defined as less than 30 kg for men and less than 20 kg for women using the average value of two handgrip measurements of the dominant hand. Multivariable logistic regression analysis was conducted to assess the association between muscular strength and MCI. Results A total of 32 715 participants were included (mean age 62 ± SD 15.6 y and 51.7% female). The prevalence of MCI and weak handgrip strength was 15.3% (95% CI, 14.4%‐16.3%) and 46.5% (95% CI, 43.6%‐49.5%), respectively. After adjustment for potential confounders, weak handgrip strength was associated with 1.41 (95% CI, 1.23‐1.61) times higher odds for MCI. The corresponding figures for those aged 50 to 64 years and 65 years or older were 1.35 (95% CI, 1.14‐1.60) and 1.54 (95% CI, 1.27‐1.86), respectively. Conclusions Muscular weakness may provide a clinically useful indicator of MCI risk. Increasing our understanding of the connection between muscular and cognitive function could ultimately lead to the development and broader implementation of resistance training interventions targeting both physical and cognitive health.

Aim: The purpose of this study was to verify the association of cognitive function with health-related variables, diseases, and social activities. Methods: Data from the 2016 Korean Longitudinal Study of Aging were analyzed. The participants of that study were 5678 adults aged 60 years or older living in 17 major Korean regions nationwide. Results: Hierarchical multiple regression analyses indicated that gender, age, education, marital status, depressive symptoms, body mass index, regular exercise, activities of daily living, instrumental activities of daily living, hand grip strength, and social activities were all significantly associated with cognitive function in elderly Koreans. However, socioeconomic status, diabetes, smoking, alcohol consumption, attendance at school reunions, volunteer work, and participation in political or civic organizations had no impact on cognitive function. First, the results indicated that men had better cognitive function than women; likewise, married individuals and those with a higher level of education also had better cognitive function. As age increased, cognitive function declined. Second, higher body mass index was related to poorer cognitive function, whereas regular exercise was positively associated with better cognitive function. In addition, higher activities of daily living and instrumental activities of daily living scores were associated with poorer cognitive function. Third, depressive symptoms were negatively associated with cognitive function. Finally, religious activities, social activities, and participation in leisure activities, cultural events, and sports were associated with better cognitive functioning. The possibility of reverse association exists between some of the variables (e.g. religious activity and cognitive function), and it is necessary to verify this possibility through a longitudinal study. The biggest limitation is that this is a cross-sectional study, which made it unfeasible to investigate the causal pathways. Conclusions: This study suggests that regularly exercising and attending social activities each help to improve cognitive function in the elderly.
