Families and Disability Onset: Are Spousal Resources Less Important for Individuals at High Risk of Dementia?

Prevalence and determinants of self-reported functional status among older adults residing in the largest refugee camp of the world

BACKGROUND

The older adults of refugee camps might be vulnerable to exhibiting limited functional abilities because of the limited resources available to create a supportive environment for older population in the camps. This study aims to explore the prevalence and determinants of self-reported functional status among the older adults residing in the Rohingya refugee camp in Bangladesh.

METHODS

This cross-sectional study was conducted on 864 older adults aged 60 years and above living in five selected sub-camps of Rohingya refugee camp in Cox's Bazar, Bangladesh. Data were collected through face-to-face interviews of the participants between November-December 2021. Functional status was measured using the Barthel Index. Information on participants' sociodemographic characteristics, self-reported chronic diseases and lifestyle characteristics were also collected. A multiple logistic regression model was used to assess the factors associated with self-reported functional abilities among the participants.

RESULTS

The overall percentage of people having limited self-reported functional ability was 26.5% (male: 22.6% and female: 31.5%) with inability most found in grooming (33.2%), bathing (31.8%), stair using (13.2%) and mobility (10.7%). In the final adjusted model, having age of 80 years or more (aOR = 2.01,95% CI: 1.08,3.75), being female (aOR = 1.44, 95% CI: 1.04,2.0), having low memory or concentration (aOR = 1.83, 95% CI: 1.30,2.56), loneliness (aOR = 2.89, 95% CI:1.74,4.80) and living with aid alone (aOR = 2.89, 95% CI: 1.74,4.80) were found to be associated with self-reported limited functional ability.

CONCLUSION

The findings of this study highlight the need for attention from policymakers and public health practitioners on addressing functional limitations among older adults residing in the Rohingya refugee camp. Our findings emphasize the need for the development of comprehensive interventions that can address the wider unmet needs (e.g., ensuring family/caregiver support, engaging in social and physical activities, providing nutritional support packages, etc.) to improve the health and well-being of older Rohingya adults.

Exploring member’s knowledge sharing intention in online health communities: The effects of social support and overload

This study explores the determinants of members’ participation intention in online health communities (OHC) from both the facilitators and barriers points of view. From the facilitators perspective, each member’s subjective well-being plays a crucial role in sharing intention. On the other hand, from the barriers point of view, social network site exhaustion would negatively affect. The survey was conducted on two online support groups, including parents of children with autism spectrum disorder and caregivers of dementia disease. This study collected 330 questionnaires from social network sites to examine the research model. The results showed that social support positively affects members’ self-efficacy; in turn, self-efficacy has a positive effect on subjective well-being. Overload has an impact on psychological distress. Moreover, members’ subjective well-being determined their knowledge sharing intention.

Influence of social support on limitation in daily living among older persons in Malaysia

AIM

Studies on the influence of social support on activity limitation among older persons remain limited. A better understanding of this relationship will help with resource planning and policy making aimed to reduce burden of care. The objective of this study was to assess the influence of social support on limitation in daily living among older persons in Malaysia.

METHODS

Data from the National Health and Morbidity Survey 2018, a nation-wide, cross-sectional survey using a two-stage stratified sampling design, were analyzed. A representative sample of individuals aged ≥60 years identified through national sampling frames throughout Malaysia was included. Face-to-face interviews were conducted using validated questionnaires on activities of daily living (ADL) and instrumental ADL (IADL). Social support was measured using the Duke Social Support Index.

RESULTS

The overall prevalence of the presence of any limitations in ADL and IADL was 17.0% and 42.9% respectively. Overall prevalence of the older persons with low to fair social support was 30.8% and high to very high social support was 69.2%. Logistic regression analysis identified the following factors as being associated with limitations in ADL and IADL: being female, of older age, having a monthly income <RM 1000 and reporting low to fair social support.

CONCLUSION

Low social support was associated with limitation in daily living among older persons in Malaysia. Future studies should consider evaluating the potential benefits of increasing social support on the activity limitation of our older population. Geriatr Gerontol Int 2020; 20: 26-32.

The Relationship between Physical Exercise and Cognitive Function in Korean Middle Aged and Elderly Adults without Dementia

This study investigated the association between physical exercise and cognitive function in Koreans aged 45 years or above without dementia. Data from the 2006 to 2018 Korean Longitudinal Study of Aging (KLoSA) were used. The general characteristics of the study population were investigated using analysis of variance (ANOVA). The association between total exercise time per week and cognitive function, measured based on the Mini-Mental State Examination (MMSE) scores, was investigated using the generalized estimating equation (GEE) model. Subgroup analysis was conducted based on age, educational level, and marital status. A total of 8888 participants were investigated, of which 5173 (58.2%) individuals did not exercise regularly. Among participants who did exercise, 676 (7.6%) individuals were categorized into the Q1, 1157 (13.0%) into the Q2, 908 (10.2%) into the Q3, and 974 (11.0%) into the Q4 group. The mean MMSE score was 26.81 ± 3.17. Compared to the ‘no’ exercise group, better MMSE scores were found in the Q1 (β: 0.3523, p ≤ 0.0001), the Q2 (β: 0.2011, p ≤ 0.0001), the Q3 (β: 0.4075, p ≤ 0.0001), and the Q4 groups (β: 0.3144, p ≤ 0.0001) after adjustment. The magnitude of this association was stronger in participants aged 65 years or above and in single or separated individuals. The findings of this study confirm a positive association between physical exercise and MMSE scores in the middle aged and elderly.

Incidence Rates of Disability and Its Associated Factors among Korean Community-Dwelling Older Adults

BACKGROUND

We aimed to identify incidence rates of disability and its associated factors among Korean community-dwelling older adults.

METHODS

The sample included 1,739 Koreans aged over 65 yr from the Korean Longitudinal Study of Aging (2006-2016) who reported no limitations in activities of daily living (ADL) or instrumental activities of daily living (IADL) at baseline (2006) and had complete data for other covariates. ADL, IADL, socio-demographic, lifestyle, and health-condition data were collected and analyzed using multiple logistic regression models.

RESULTS

The 10-yr incidence rates of ADL and IADL disability in subjects with no disability at baseline were 11.6% and 21.6%, respectively. After adjusting for socio-demographic, lifestyle, and health-condition factors, the incidence of ADL disability was higher in women (odds ratio [OR] =1.418, 95% confidence interval [CI]=1.102-2.613) and increased with age (OR=1.170, 95% CI=1.133-1.208), multi-morbidity (OR=1.194, 95% CI=1.015-1.406), and obesity (OR=1.563, 95% CI=1.057-2.311). It decreased in subjects living alone (OR=0.531, 95% CI=0.328-0.856). The incidence of IADL disability increased with age (OR=1.131, 95% CI=1.102-1.161), multi-morbidity (OR=1.199, 95% CI=1.054-1.365), and cognitive disability (OR=1.422, 95% CI=1.083-1.866) and decreased for subjects living alone (OR=0.484, 95% CI=0.328-0.715) and with overweight (OR=0.725, 95% CI=0.532-0.988).

CONCLUSION

Incidence rates of disability differed considerably based on socio-demographic, lifestyle, and health-condition factors. These results suggest the importance of identifying factors that can decrease the risk of disability in this group and of prevention efforts in populations with a higher disability risk.

Baby Boomers as Caregivers: Results From the Behavioral Risk Factor Surveillance System in 44 States, the District of Columbia, and Puerto Rico, 2015-2017

INTRODUCTION

Baby boomers, people born from 1946 through 1964, represent a substantial portion of the US population. Generally, baby boomers have more chronic disease and disability than those in the previous generation. Frequently, they also provide informal care to others. The objective of our study was to estimate the prevalence of informal caregiving among baby boomers and compare the health of baby boomer caregivers and noncaregivers.

METHODS

Using data from the Behavioral Risk Factor Surveillance System (2015-2017) for 44 states, the District of Columbia, and Puerto Rico, we classified 109,268 baby boomers as caregivers or noncaregivers and compared their general health (poor or fair vs good, very good, or excellent), chronic health conditions, and frequent mental distress (FMD). FMD was defined as 14 days or more of poor mental health in the past month. We used log-binomial regression to calculate prevalence ratios, adjusted for age and sex (aPRs), and to separately estimate aPRs for fair or poor health and FMD or at least one chronic health condition.

RESULTS

One in 4 baby boomers (24.2%) were caregivers. In adjusted models, male caregivers had a higher prevalence of fair to poor health than noncaregivers (aPR = 1.17; 95% confidence interval [CI], 1.06-1.29; P = .001). More caregivers than noncaregivers had at least 1 chronic health condition (aPR = 1.10, 95% CI, 1.07-1.13; P < .001) and more often had FMD (aPR = 1.39; 95% CI, 1.26-1.53; P < .001).

CONCLUSION

Our study showed these caregivers had more chronic health conditions and more often had FMD than noncaregivers. The health of baby boomer caregivers is a public health priority, as these caregivers might need support to maintain their own physical and mental health.

Do older adults with Alzheimer's disease engage in estate planning and advance care planning preparation?

OBJECTIVES

This study investigated the estate planning and advance care planning (ACP) of older adults diagnosed with Alzheimer's disease (AD) for the presence of (1) a valid will, (2) a durable power of attorney for health care, and (3) a living will.

METHOD

We analyzed 10,273 adults aged 65 and older from the 2012 Health and Retirement Study (HRS) using multilevel logistic regression.

RESULTS

We found that a diagnosis of AD was significantly associated with the ACP variables. Older adults with AD were more likely to assign a durable power of attorney for health care and have a written living will than older adults without an AD diagnosis. However, we found no significant association between a diagnosis of AD and having a valid will. These findings were robust when adjusting for demographic and socioeconomic variables. Other factors decreased engagement in estate planning and ACP, including lower socioeconomic status, being male, and being a minority.

CONCLUSION

Our findings suggest that a diagnosis of AD is associated with more engagement in ACP for individuals and their families, but important barriers exist for people with fewer resources.

Spouse's subjective social status predicts older adults' prospective cognitive functioning

OBJECTIVES

The current study aims to investigate the association between subjective social status (SSS) and prospective cognitive functioning of older adults and their spouses, and to explore the potential mediating roles of health habits and physical activities in this association.

METHOD

Using the longitudinal data of 512 pairs of community-dwelling older couples aged 65-91 years (M = 72.2 ± 4.6), we tested the effects of SSS in cognitive functioning using an Actor-Partner Interdependence Model. SSS was measured by a self-anchoring social ladder, and cognitive functioning was measured by the Mini-Mental State Examination at baseline and 4-year follow-up. Socioeconomic status (i.e. education) was tested as a moderator, and physical activity (measured by the Physical Activity Scale for the Elderly) as well as health habits (i.e. tobacco and alcohol consumption) were included as potential mediators.

RESULTS

A partner effect of SSS was found only in the low-education group, in which the wife's higher level of SSS in the community was associated with the husband's better cognitive functioning in the follow-up. A small proportion of this effect was found to be partially mediated by participation in housework, such that the wife's higher SSS was associated with the husband's increased housework activity, which was related to higher prospective cognitive functioning.

CONCLUSION

By examining the dyadic effects of SSS with a longitudinal design, our findings extended the understanding on how subjective social status influenced older couples' cognitive health, and provided evidence-based insights for future studies on cognitive health in later life.

Cohort study on living arrangements of older men and women and risk for basic activities of daily living disability: findings from the AGES project

Background

Living arrangements of older adults have changed worldwide with increasing solitary and non-spouse households, which could affect social care systems. However, the relationship between these households and disability onset has remained unclear. We examined the relationship between living arrangements and the onset of basic activities of daily living disability in older adults, with a focus on gender differences and cohabitation status of those without a spouse.

Methods

Data from 6600 men and 6868 women aged 65 years or older without disability were obtained from the Aichi Gerontological Evaluation Study Project in Japan. Onset of disability was followed for 9.4 years. Disability was assessed based on Long-term Care Insurance System registration. A hierarchical Cox proportional hazards model was conducted to examine the risk of living alone and living only with non-spousal cohabitants compared to those living with spouses.

Results

Men living only with non-spousal cohabitants and those living alone were significantly more likely to develop disability after controlling for health and other covariates (hazard ratio = 1.38 and 1.45, respectively), while a significant difference was found only for women living alone (hazard ratio = 1.19). The risk of living with non-spousal cohabitants was marginally stronger in men, indicated by the interaction effect model (p = .08). A series of hierarchical analyses showed that social support exchange explained 24.4% and 15.8% of the excess risk of disability onset in men living alone and those living only with non-spousal cohabitants, respectively. A subsequent analysis also showed that support provision by older adults more greatly explained such excess risk than receiving support from others.

Conclusions

Older men without spouses were more likely to develop disability onset regardless of cohabitants. Health professionals should consider programs that enhance social support exchange, particularly support provision by older adults who are at risk of disability.

Spouse with schizophrenia and risk of dementia

Increased prevalence of lifestyle risk factors or shared etiology may underlie the association between schizophrenia and the subsequent risk of dementia. We explored the association between having a spouse with schizophrenia and the risk of dementia. We found a positive relationship between having a spouse with schizophrenia and vascular dementia in individuals without a mental disorder themselves but no association between having a spouse with schizophrenia and Alzheimer's dementia. As spouses share environmental risk factors and lifestyle, this might suggest that the excess risk of dementia in probands with schizophrenia could be ascribed to the unhealthy living environment among individuals with schizophrenia.
