ABSTRACTBackground:Aging is accompanied by cognitive decline that is escalated in older adults reporting extreme sleep duration. Social relationships can influence health outcomes and thus may qualify the association between sleep duration and cognitive function. The present study examines the moderating effects of marital status, household size, and social network with friends and relatives on the sleep–cognition association among older adults.Methods:Data (N = 4,169) came from the Social Isolation, Health, and Lifestyles Survey, a nationally representative survey of community-dwelling older Singaporeans (≥ 60 years). Sleep duration and social relationships were self-reported. Cognitive function was assessed with the Short Portable Mental Status Questionnaire.Results:Regression analysis revealed that the inverted U-shaped association between sleep duration and cognitive function was less profound among older adults who were married (vs. unmarried) and those who had stronger (vs. weaker) social networks. In contrast, it was more prominent among individuals who had more (vs. fewer) household members.Conclusions:Being married and having stronger social networks may buffer against the negative cognitive impact of extreme sleep duration. But larger household size might imply more stress for older persons, and therefore strengthen the sleep duration–cognitive function association. We discuss the potential biological underpinnings and the policy implications of the findings. Although our findings are based on a large sample, replication studies using objective measures of sleep duration and other cognitive measures are needed.

Abstract Social relationships play an important role in cognitive health and aging. However, it is unclear how older adult’s cognitive function affects their everyday social interactions, especially for those with mild cognitive impairment (MCI). This study examined whether older adults with intact cognition vs. MCI differed in their daily social interactions. Community-dwelling older adults from the Einstein Aging Study (N=244, 70-91 yrs) reported their social interactions five times daily for 14 consecutive days using smartphones. Compared to those with normal cognitive function, older adults with MCI reported less frequent positive social interactions (p=0.012) and in-person social activities (p=0.006) on a daily basis. These two groups, however, did not show significant differences in their social relationships assessed by a conventional global questionnaire. The results support that, relative to global social relationships, daily social interactions are more sensitive, ecologically valid social markers that can facilitate the early detection of MCI.

The Relationship

Abstract Background Physical fitness declines with age. Low levels of physical fitness appear to be a risk factor of cognitive impairment. Literature elucidates social networking as a potential moderator for the relationship between physical fitness and cognitive impairment. Present study aimed to examine the relationship between physical fitness and cognitive function among community-dwelling older Malaysians, and if social network moderates said relationship. Methods Data of 2322 representative community-dwelling older adults were obtained from the first wave of the “Longitudinal Study on Neuroprotective Model for Healthy Longevity” national survey. Cognitive function, physical fitness and social network was assessed through Malay-version of Mini-Mental State Examination, 2-min step test and Lubben Social Network Scale-6 respectively. Moderated hierarchical multiple regression was employed to investigate if social networks moderate the relationship between physical fitness and cognitive function. Results A positive association between physical fitness and cognitive function were found upon controlling for covariates. Moderated hierarchical multiple regression revealed social networks to be a moderator of the association between physical fitness and cognitive function. When physical fitness was low, those with small social network revealed lowest cognitive function. Conclusions Social networks moderated the relationship between physical fitness and cognitive function as older adults with low levels of physical fitness and small social networks revealed lowest cognitive function. Therefore, community support or peer-based interventions among physically unfit older adults should be implemented to promote cognitive function.

Aims: To examine the association of social networks and community engagement with cognitive impairment among community-dwelling Chinese older adults. Methods: From November 2017 to May 2018, we selected 1,115 elderly individuals from 3 Chinese communities (Beijing, Hefei, and Lanzhou) using a random-cluster sampling method, and recorded data on demographics, social network characteristics, community activities, and cognitive function. The odds ratios (ORs) of these associations were adjusted for potential confounders in logistic regression models. Results: The prevalence of cognitive impairment was 25.7% (n = 287). An adequate social network (OR 0.55; 95% confidence interval [CI] 0.33–0.91) and enough social support from friends (OR 0.43; 95% CI 0.29–0.62) were negatively associated with cognitive impairment. Family support was not significantly associated with cognitive impairment (OR 0.64; 95% CI 0.34–1.21). Taking part in elderly group travel, communication with others using WeChat, and community activities such as Tai Chi and walking together were negatively associated with cognitive impairment. Conclusion: Social network characteristics and community engagement were found to be related to cognitive function among community-dwelling Chinese elderly adults.

The Impact

ABSTRACTBackground:Durations of nocturnal sleep and daytime nap influence the well-being of older adults. It is thus essential to understand their determinants. However, much previous research did not assess sleep duration and nap duration individually, and longitudinal data is lacking. This study aimed at examining the impact of demographic, psychosocial, and health factors, including ethnicity, social networks outside the household, smoking and physical exercise on sleep duration and nap duration among community-dwelling elderly.Methods:Our study involved over 2,600 older adults (≥60 years) from a longitudinal, nationally representative survey – the Panel on Health and Ageing of Singaporean Elderly. Sleep and nap durations at Time 2 (two years later) were regressed on predictors measured at Time 1.Results:Time 2 short nocturnal sleep duration was predicted by Malay ethnicity (relative to Chinese and Indian), older age, lower education level, more depressive symptoms, and obesity, whereas future long nocturnal sleep duration was predicted by weaker social networks, older age, and more chronic diseases. Furthermore, smoking, obesity, Malay or Indian (relative to Chinese), older age, male gender, and cognitive impairment predicted longer daytime nap duration in the future.Conclusions:Older adults’ nocturnal sleep and daytime nap durations may be affected by different demographic, psychosocial, and health factors. Thus, it is important to differentiate these two attributes in this age group.

IntroductionInterpersonal stressors and social isolation are detrimental for emotional health, but how these factors are related to loneliness and altogether influence risk for mental disorders is not well understood.ObjectivesTo examine the mediating role of loneliness in the associations of relationship quality and social networks with depressive symptoms, anxiety, and worry among a sample of Irish men and women in late-life.AimsTo determine the gender-specific risk for mental disorder associated with poor social relationships and loneliness among older adults.MethodsData came from the Irish Longitudinal Study on Ageing (TILDA). Nationally representative data on 6105 community-dwelling adults aged > 50 years were analyzed. Follow-up data was obtained two years after cohort inception. Multivariable linear regressions and mediation analyses were used to assess the associations. Analyses were stratified by gender.ResultsBetter spousal relationship quality was protective against depressive symptoms and worry for men. For both genders, support from friends was protective against depressive symptoms, and better relationship quality with children was protective against depressive symptoms and worry. Social network integration was inversely related to depressive symptoms for men. Loneliness significantly mediated most associations (Tables 1–3).ConclusionsHigh quality spousal relationships and social integration appear to play a more central role for mental health among men than for women. For both genders, poor social relationships increase feelings of loneliness, which in turn worsens mental health. Interventions to improve relationship quality and social networks, with a focus on reducing loneliness, may be beneficial for the prevention of mental disorders among older adults.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract The purpose of this study was to examine the associations between tooth/gums symptoms and changes in cognitive function. We used data from the Population Study of Chinese Elderly in Chicago, a two-wave epidemiological study of 2,713 U.S. Chinese older adults. We selected self-reported oral (tooth and gum) symptoms as independent variables. We measured global function and three cognitive domains: episodic memory, executive function and working memory. Adjusting for sociodemographic and health-related characteristics, participants who reported having teeth symptoms at baseline, experienced their global cognition and episodic memory decrease (both p<0.05). Participants who reported having teeth symptoms at baseline, experienced a faster rate of decline in global cognition for every additional year. However, this effect disappeared once we adjusted for all covariates. We found no significant relationship between baseline gum symptoms and change of cognitive function. Future research directions, clinical and policy implications will be discussed.

Community Dwelling Older Adults

This study examined the prevalence of cognitive impairment among older adults in central Vietnam and the roles of communication (with or without communication devices) in the association between cognitive impairment and hearing loss. This cross-sectional study was performed on 725 randomly selected community-dwelling older adults aged ≥60 years from Thua Thien Hue province, Vietnam. Participants attended a face-to-face survey. Sociodemographic characteristics, social interaction with or without communication devices, health status and cognitive function using the Mini-Mental State Examination were reported. Ordinal logistic regression analysis was performed to quantify the association between hearing loss and cognitive function by frequency of communication with and without devices. Mild and severe cognitive impairment had prevalence rates of 23.6% and 19.3%, respectively. Cognitive impairment was more prevalent among older adults with hearing-loss, vision loss and difficulties with instrumental activities of daily living (IADL). The association between hearing loss and cognitive impairment was not significant when older adults had frequent communication with others using devices. This study presented the relatively high prevalence of cognitive impairment in community-dwelling older adults in Vietnam. Frequent communication using devices attenuated the association between hearing loss and cognitive impairment.

Background: Epigenetic age acceleration has been studied as a promising biomarker of age-related conditions, including cognitive aging. This pilot study aims to explore potential cognitive aging-related biomarkers by investigating the relationship of epigenetic age acceleration and cognitive function and by examining the epigenetic age acceleration differences between successful cognitive aging (SCA) and normal cognitive aging (NCA) among Korean community-dwelling older adults (CDOAs). Methods: We used data and blood samples of Korean CDOAs from the Korean Frailty and Aging Cohort Study. The participants were classified into two groups, SCA (above the 50th percentile in all domains of cognitive function) and NCA. The genome-wide DNA methylation profiling array using Illumina Infinium MethylationEPIC BeadChip was used to calculate the following: the DNA methylation age, universal epigenetic age acceleration, intrinsic epigenetic age acceleration (IEAA), and extrinsic epigenetic age acceleration (EEAA). We also used Pearson correlation analysis and independent t-tests to analyze the data. Results: Universal age acceleration correlated with the Frontal Assessment Battery test results ( r = −0.42, p = 0.025); the EEAA correlated with the Word List Recognition test results ( r = −0.41, p = 0.027). There was a significant difference between SCA and NCA groups in IEAA ( p = 0.041, Cohen’s d = 0.82) and EEAA ( p = 0.042, Cohen’s d = 0.78). Conclusions: Epigenetic age acceleration can be used as a biomarker for early detection of cognitive decline in Korean community-dwelling older adults. Large longitudinal studies are warranted.
