Longevity and Health: Trends in Functional Limitations and Disability Among Older Adults in Portugal, 1985–2005

Socioeconomic status and ADL disability of the older adults: Cumulative health effects, social outcomes and impact mechanisms

INTRODUCTION

Socioeconomic status (SES) is one of the important indicators affecting individual's social participation and resource allocation, and it also plays an important role in the health shock of individuals. Faced by the trend of aging society, more and more nations across the world began to pay attention to prevent the risk of health shock of old adults.

METHODS

Based on the data of China Health and Retirement Longitudinal Study (CHARLS) in 2013, 2015 and 2018, this study uses path analysis and ologit model to empirically estimate the effects of SES and health shock on the activities of daily living (ADL) disability of old adults.

RESULTS

As a result, first, it was found that SES has significant impact on the disability of old adults. Specifically, economic conditions (income) plays dominant role. Economic status affects the risk of individual disability mainly through life security and health behavior. Secondly, SES significantly affecting health shock, with education and economic status showing remarkable impact, and there is an apparent group inequality. Furthermore, taking high education group as reference, the probability of good sight or hearing ability of the low education group was only 49.76% and 63.29% of the high education group, respectively, while the rates of no pain and severe illness were 155.50% and 54.69% of the high education group. At last, the estimation of path effect of SES on ADL disability indicates evident group inequality, with health shock plays critical mediating role.

CONCLUSIONS

SES is an important factor influencing residents' health shock, and health shocks like cerebral thrombosis and cerebral hemorrhage will indirectly lead to the risk of individual ADL disability. Furthermore, among the multi-dimensional indicators of SES, individual income and education are predominant factors affecting health shock and ADL disability, while occupation of pre-retirement have little impact.

Psychosocial aspects and support networks associated with disability in two longevous populations in Brazil: a cross-sectional study

BACKGROUND

Among the oldest old, aged 80 years and over, the prevalence of disability is higher than in other age groups and can be considered a predictor of mortality.

OBJECTIVE

To evaluate how psychosocial aspects and support networks influence the disability of these oldest-old individuals, performing a comparison between two longevous populations, one living in one of the poorest regions of Brazil, in the backlands of Paraíba, and another living in one of the largest urban centres in Latin America.

METHOD

A cross-sectional study in which 417 oldest-old persons aged 80 years and older were interviewed, with data collected through the "Health, Welfare and Ageing" survey conducted in two Brazilian cities. Disability was assessed by reporting the need for assistance in Activities of Daily Living (ADLs) and Instrumental Activities of Daily Living (IADLs). Bivariate and multiple analyses were performed using R statistical software.

RESULTS

Food insufficiency in the first years of life had negative repercussions on the disability of oldest old people living in the northeast. On the other hand, in this region, older people have a higher rate of support and live longer with their peers, which may contribute to reducing feelings of loneliness, depressive symptoms, and worse self-perception of health. In the Southeast, financial constraints, subjective poverty, and unmet needs may favour the development of functional limitations between long-lived people.

CONCLUSION

Our findings indicate that regional differences in Brazil may influence the disability of older people aged 80 and older. In northeast Brazil, having no partner may contribute to disability for ADLs and IADLs; while, in the longevous population of São Paulo, having a worse self-rated health may contribute to disability for IADLs.

Recovery from physical limitations among older Mexican adults

OBJECTIVES

This paper examines the key determinants of the likelihood of recovery from a physical disability among older adults.

METHODS

Data come from the Mexican Health and Aging Study (MHAS), a national sample of adults born in 1951 or earlier, including a baseline survey in 2001 and follow-ups in 2003, 2012 and 2015. At baseline, we divided our sample of older adults aged 60+ by dimensions of physical limitations (ADLs, IADLs, mobility) and classified respondents as having physical limitations in zero, one, two or three dimensions. Each respondent was then categorized as "same", "worse", "improved" or "died" depending on the number of physical dimensions with a limitation in a 2-year span (2001-2003) and again, separately, in a 3-year span (2012-2015). We then used a multinomial logistic regression to analyze the relative risk of transitioning from one category to another.

FINDINGS

Around 21 % of our sample exhibited some recovery in 2003 and around 20 % recovered in 2015. Age, gender, poor self-rated health, depression and some chronic conditions were significant for shifting the relative risk from staying the same to getting worse, dying or even improving.

CONCLUSIONS

Disability from a physical limitation is a reversible and dynamic process. Our results reflect the importance of considering the dimensions of physical ability while analyzing recovery, and illustrate that the presence of a chronic condition or depressive symptoms does not necessarily imply permanent disability.

Functional limitation trajectories and their determinants among women in the Philippines

BACKGROUND

Limited evidence exists regarding how functional limitation patterns of women in developing countries unfold through midlife and into old age, a critical period during which the tendency to develop severe problems is fomented.

OBJECTIVE

Functional limitation prevalence and patterns through midlife into early old age, and their determinants, are examined among women in the Philippines.

METHODS

Data from the Cebu Longitudinal Health and Nutrition Study are monitored from 1994 to 2015. Patterns are categorized using group-based trajectory modeling. Predictors of group membership are modeled.

RESULTS

About half responding to all survey waves report functional limitation at least once over the study period. Movements in and out of functional limitation states are common. Between age 30 and 70, trajectories are categorized into four groups: 1) robust, 2) late onset, 3) early onset, and 4) recovery. Being married, living in a nuclear household, higher successful birth ratio, and higher education associate with favorable trajectories. More births, higher age at first birth, wealth, and urbanicity associate with less favorable trajectories.

CONCLUSION

Many possible routes into and out of functional limitation exist. The manifold patterns can be grouped into common trajectories. A number of earlier life characteristics associate with these trajectories.

CONTRIBUTION

This is the first analysis to ascertain common functional limitation trajectories and earlier life predictors among women as they age in a high fertility developing country setting. Recognizing these is an important step toward understanding global health given aging of the population and the likelihood of functional problems developing in women as they move into old age.
