Leisure time activities as mediating variables in functional disability progression: An application of parallel latent growth curve modeling

Trajectories and influencing factors of cognitive function and physical disability in Chinese older people

Introduction

Dementia and physical disability are serious problems faced by the aging population, and their occurrence and development interact.

Methods

Based on data from a national cohort of Chinese people aged 60 years and above from the China Health and Retirement Longitudinal Survey from 2011 to 2018, we applied the group-based trajectory model to identify the heterogeneous trajectories of cognitive function and physical disability in participants with different physical disability levels. Next, multinomial logistic regression models were used to explore the factors affecting these trajectories.

Results

The cognitive function trajectories of the Chinese older people could be divided into three characteristic groups: those who maintained the highest baseline level of cognitive function, those with a moderate baseline cognitive function and dramatic progression, and those with the worst baseline cognitive function and rapid-slow-rapid progression. The disability trajectories also fell into three characteristic groups: a consistently low baseline disability level, a low initial disability level with rapid development, and a high baseline disability level with rapid development. Compared with those free of physical disability at baseline, a greater proportion of participants who had physical disability at baseline experienced rapid cognitive deterioration. Education, income, type of medical insurance, gender, and marital status were instrumental in the progression of disability and cognitive decline in the participants.

Discussion

We suggest that the Chinese government, focusing on the central and western regions and rural areas, should develop education for the older people and increase their level of economic security to slow the rate of cognitive decline and disability among this age group. These could become important measures to cope with population aging.

Relationship Between Multiple Roles and Leisure-Time Physical Activities in Working-Age Women

BACKGROUND

Multiple role theory has proven effective in predicting variations in health, and a growing body of research has shown the importance of taking women's roles into account when analyzing physical activity levels. Nonetheless, researchers have yet to characterize the interaction between the various roles played by women and their physical activity.

PURPOSE

The objectives of this study were to elucidate the relationship between multiple roles and leisure-time physical activities (LTPAs) and to determine whether LTPA varies among women across different roles.

METHODS

Data were derived from the 2013 National Health Interview Survey database provided by the Health Promotion Administration of Taiwan's Ministry of Health and Welfare, which includes 5,147 working-age women. The current study focused on women aged 20-50 years. The roles considered in this study included living with a partner, living with children, and employment status. LTPA levels were categorized as regular, inactive, or insufficient based on the LTPA metabolic equivalent in the previous week. The associations among level of LTPA, multiple roles, and demographic characteristics were analyzed using multiple regression analysis.

RESULTS

We found single mothers with children to be more inactive than partnered mothers, and women living with a partner and those living with children were more likely to be inactive, whereas women working full-time were not at risk of inactivity. Women who assumed a larger number of roles were at a greater risk of inactivity. These findings are consistent with role strain theory.

CONCLUSIONS

Single mothers with children are more inactive than partnered mothers, and appropriate social support programs are necessary to reduce further disparities. Second, multiple demands on working-age women limit the time available for LTPAs, particularly among women living with a partner and children and engaged in full-time work. A physical activity intervention is a program or initiative designed to promote physical activity and improve health outcomes. We should develop and provide sustainable physical activity resources through the help of partners' housework to better promote physical activity intervention for working-age women.

Television watching, reading, cognition, depression and life satisfaction among middle-aged and older populations: A group-based trajectory modelling analysis of national data

This retrospective cohort study aimed to identify heterogeneous cognition, depression, and life satisfaction trajectory groups, and to examine the independent contributions of watching television and reading to these trajectories among middle-aged and older adults. A sample was taken from the Taiwan Longitudinal Study on Aging (TLSA) with measures of cognition, depression, life satisfaction, watching television, and reading during 12 years of follow-up (N = 4440). Group-based trajectory models and multinomial logistic regressions were used. The findings showed that the cohort was separated into three global cognition groups of low-cognition (n = 376), declining-cognition (n = 805), and maintained-cognition (n = 2718); three episodic memory groups of high-declining (n = 540), middle-stable (n = 2066), and improving groups (n = 1293); three depression groups of low-to-low (n = 2571), median-to-high (n = 960), and high-to-high groups (n = 368); and three life satisfaction groups of low- (n = 1133), middle- (n = 977), and high-level groups (n = 1789). Also, the findings demonstrated that after adjusting for covariates, those who did not watch television or read at the baseline had independently significantly increased odds of having lower global cognitive function, higher depression, and lower life satisfaction over time versus those who watched television or read almost every day. Based on the findings obtained, group-based trajectories of cognition, depression, and life satisfaction scores identified distinct subgroups among TLSA participants. Moreover, the findings suggest that healthcare providers need to develop more targeted population interventions to ensure successful aging. Healthcare providers can encourage older adults, particularly new retirees, to participate in leisure activities (i.e., watching television and reading) to reduce prevalence rates of cognitive impairment and depression.

Differing determinants of disability trends among men and women aged 50 years and older

Background

Researchers have emphasized the importance of examining how different factors affect men’s and women’s functional status over time. To date, the literature is unclear about whether sex affects the rate of change in disability in middle to older age. Researchers have further emphasized the importance of examining how different factors affect men’s and women’s functional status over time. We examined (a) sex differences in disability trends and (b) the determinants of the rate of change in disability for men and women 50 years and older.

Methods

This study utilized the Taiwan Longitudinal Study on Aging Survey, a nationally representative database (four waves of survey data 1996–2007, N = 3429). We modeled and compared the differences in disability trends and the influences of determinants on trends among men and women using multiple-indicator and multiple-group latent growth curves modeling (LGCM). Equality constraints were imposed on 10 determinants across groups.

Results

Once disability began, women progressed toward greater disability 18% faster than men. Greater age added about 1.2 times the burden to the rate of change in disability for women than men (p < 0.001). More comorbidities also added significantly more burden to baseline disability and rate of change in disability among women than men (p < 0.001), but women benefited more from higher education levels in lower baseline disability and slower rate of change. Having a better social network was associated with lower baseline disability among women only (p < 0.05). For both men and women, physically active leisure-time activities were beneficial in lower baseline disability (p_{men and women} < 0.001) and rate of change in disability (p_men < 0.01; p_women < 0.05), with no significant differences between groups.

Conclusions

Age may widen the sex gap in the rate of change in disability. However, both sexes benefit from participating in leisure-time activities. Promoting health literacy improves health outcomes and physical function among women.

Participation in recreational activities varies with socioeconomic position and is associated with self-rated health and well-being

•

This study shows social inequalitues in recreational activity participation (RAP).

•

Regardless of educational level, RAP was associated with better self-rated health.

•

RAP may modify social inequality in self-rated health and quality of life.

Recreational activities may promote and maintain health and well-being, but empirical evidence is limited. The aim of this study was to explore socioeconomic variations in participation in recreational activities in the local community and to examine associations with health and well-being in the general population.

Participants ≥ 16 years from the Danish Capital Region Health Survey, conducted in 2017 (N = 55,185, response rate 52.6%) were included. Participation in community-based recreational activities, self-rated health, quality of life, and health status was assessed by questionnaire. Socioeconomic variables (educational level, occupational and marital status) were obtained from national registers. Multiple logistic regression models were used to examine associations.

Less than half of the population participated in community-based recreational activities. Individuals with a higher educational level were 55% more likely to participate in recreational activities compared to those with a lower educational level (OR = 1.55, CI:1.45–1.66). Individuals with a low educational level who participated in recreational activities, were more likely to have an excellent/good quality of life (OR = 2.03 (95% CI:1.86–2.21)) and an excellent/very good self-rated health (OR = 1.61 (95% CI:1.51–1.71)), than those who did not participate in recreational activities.

Regardless of educational level, recreational activity participation was associated with better self-rated health and quality of life. Thus, to counter-balance social inequality in health, a focus on participation in recreational activities is important when planning community public health interventions.

Systematic review of methods used to study the intersecting impact of sex and social locations on health outcomes

PURPOSE

Independent health impacts of sex or social circumstances are well-studied, particularly among older adults. Less theorized or examined is how combinations or intersections of these underpin differential health effects. Nevertheless, and often without naming it as such, an intersectional framework aligns with studies of social determinants of health, life-course epidemiology and eco-epidemiology. In this systematic review we examined and aimed to identify research methods used to operationalize, whether intentionally or inadvertently, interconnected effects of sex and social locations on health outcomes for 45+ year olds.

METHODS

Using broad search terms, numerous databases, and following Prisma guidelines, 732 of 9214 papers initially identified, met inclusion criteria for full review.

RESULTS

Of the 501 papers included after full review, methods used in considering intersections of sex and social circumstances/location(s) included regression (112 of 365 papers), growth curves (7 of 22), multilevel (15 of 25), decomposition (6 of 9), mediation (10 of 17), structural equation modelling (23 of 25), and other (2 of 3). Most (n = 157) approximated intersectional analyses by including interaction terms or sex-stratifying results.

DISCUSSION

Few authors used the inherent strength of some study methods to examine intersecting traits. As even fewer began with an intersectionality framework their subsequent failure to deliver cannot be faulted, despite many studies including data and methodologies that would support intersectional analyses. There appeared to be a gap, not in analytic potential but rather in theorizing that differential distributions of social locations describe heterogeneity within the categories 'men' and 'women' that can underlie differential, gendered effects on older adults' health. While SEM, mediation and decomposition analyses emerged as particularly robust methods, the unexpected outcome was finding how few researchers consider intersectionality as a potential predictor of health.
