Trends in late-life disability in Taiwan, 1989-2007: the roles of education, environment, and technology

This analysis offers the first strong evidence of trends in late-life disability in an emerging economy. For the population of Taiwan aged 65 and older, consistent measures of limitations in seeing, hearing, physical functions, instrumental activities of daily living (IADLs), and activities of daily living (ADLs) were available for three to six survey waves, depending on the outcome, from 1989 to 2007. Limitations in seeing, hearing, and IADLs declined substantially, but trends were mixed for physical functions and flat for ADLs. The remarkable reduction in difficulty telephoning, an IADL, may reflect changes in telecommunications infrastructure and highlights the roles of environment and technology in disability outcomes. Trends for urban residents were more advantageous than those for rural residents for seeing and hearing, but less so for physical functions and IADLs. Were it not for the substantial increase in educational attainment, trends in all outcomes would have been less favourable.     

Modeling Disability Trajectories and Mortality of the Oldest-Old in China

This article uses a group-based modeling approach to jointly estimate disability and mortality trajectories over time based on data from the population aged 80 and older in China, and explores relations of demographic, socioeconomic, and early-life characteristics to membership in gender-specific trajectory groups. A three-group model best fits the data for both males and females. For most groups, predicted numbers of limitations in activities of daily living (ADLs) increase with age, but the pace is gradual in some cases and rapid in others. For each gender, the estimated mortality probability trajectories for the three groups follow a hierarchy that is related to the predicted ADL counts at age 80. Only a few characteristics predict trajectory-group membership. Prior nonagricultural occupation is associated with less favorable disability trajectories for both genders. For females, rural residence, a greater number of children ever born, and having a father who did not work in agriculture are associated with more favorable trajectories. For a small group of males who received education, disability is moderate but changes little with age. Findings may reflect heterogeneity of survival among the least advantaged, as well as a possible expansion of morbidity among a small advantaged group.     

Trends in health of older adults in the United States: Past,present, future

The decline in late-life disability prevalence in the United States was one of the most important developments in the well-being of older Americans in the 1980s and 1990s, but there is no guarantee that it will continue into the future. We review the past literature on trends in disability and other health indicators and then estimate the most recent trends in biomarkers and limitations for both the population aged 65 and older and those aged 40 to 64, the future elderly. We then investigate the extent to which trends in education, smoking, and obesity can account for recent trends in limitations and discuss how these three factors might influence future prospects for late-life health. We find that improvements in the health of the older population generally have continued into the first decade of the twenty-first century. The recent increase in the proportion of the younger population needing help with activities of daily living is concerning, as is the doubling of obesity in the last few decades. However, the increase in obesity has recently paused, and favorable trends in education and smoking are encouraging.     

Was there compression of disability for older Americans from 1992 to 2003?

Medical advances and the growth of the elderly population have focused interest on trends in the health of the elderly. Three theories have been advanced to describe these trends: compression of morbidity, expansion of morbidity, and dynamic equilibrium. We applied multistate life table methods to the Medicare Current Beneficiary Survey to estimate active and disabled life expectancy from 1992 to 2003, defining disability as having difficulty with instrumental activities of daily living or activities of daily living. We found increases in active life expectancy past age 65 and decreases in life expectancy with severe disability. These trends are consistent with elements of both the theory of compression of morbidity and the theory of dynamic equilibrium.

Sociodemographic Differentials of the Self-rated Health of the Oldest-old Chinese

This study explores the correlation between sociodemographic factors and theself-rated health status of the oldest-old Chinese (80 and older). The data werefrom the Healthy Longevity Survey in China conducted in 1998. We applied astereotype ordered regression model to capture the ordinal nature of the responsevariable. We found that age group, sex, living arrangement, educational attainment,and occupational history were associated significantly with the self-rated healthstatus of the oldest-old Chinese, and the elderly with lower social status tended tonegatively evaluate health status. We reached the conclusions after controlling suchvariables as the capacity of physical performance of daily activities and chronic diseases.     

Changes in functional limitation and survival among older Taiwanese, 1993, 1996, and 1999

Using data from the Survey of Health and Living Status of the Elderly in Taiwan, we investigate changes in difficulties in walking and climbing stairs, tasks that represent basic lower-body movements less likely to be influenced by changes in environment and social roles than are activities and instrumental activities of daily living. Results are shown for unadjusted prevalence rates and rates adjusted for changes in population composition. The findings indicate that Taiwan does not appear to be experiencing the improvements in functioning witnessed recently in the United States. Prevalence of functional limitation increased between 1993 and 1996 and between 1996 and 1999. One possible reason is the change in old-age survival, which appears to have benefited those who have functional limitations, especially in a severe form. The Universal Health Insurance programme, established in 1995, may have increased access to care and thus the survival of those in poorest health.     

Income and “Outcomes” for Elderly: DO the Poor have A Poorer Life?

The objective of this paper is to analyze the relationship between income and living conditions and well-being of elderly. The best from two worlds is used for this purpose: a Danish survey covering 1440 elderly aged 72 and 77 from 1997, connected to reliable register information on income, 1988–1996. Indicators of physical activity, social and solitary activities, social contact, functional capability, loneliness and psychological well-being are constructed from the survey. Ordered logistic models are estimated controlling for demographics, education, previous occupation and whether the elderly are still working. It is found that elderly with low income levels have poorer functional capability, lower physical activity and poorer psychological well-being whereas social contact and social activities show no relationship with income. The relationship with income vanishes for solitary activities and loneliness when adding control variables. Having established that robust relations exist between income and some measures of well-being of elderly, we turn to an investigation of causality. Simultaneous models are estimated to assess whether the income relationship can be causally interpreted for functional capability and physical activity. The results show that it cannot be rejected that the income effects are causal, although care should be taken when interpreting results. We finally address our findings in the light of current and future changes regarding the size and economic well-being of the elderly population.

Gender differences in activity of daily living of the elderly in rural China: evidence from Chaohu

Using data from a sample survey, Well-being of the elderly in Anhui province, China, this paper studies the effects of health, economic and family factors on the activities of daily living (ADLs) as measures of disability for elderly men and women. The objective is to explore reasons for gender differences in ADLs in rural China. Our results suggest that higher incidence rates of chronic diseases, lower cognitive ability, as well as heavier household and daily care burdens of females, are the main factors leading to a higher prevalence of ADL disability for the female elderly.     

Residential proximity of parents and their adult offspring in the United Kingdom, 2009–10

Using data from a large household survey representative of the UK population, we studied how closely parents and adult children live to each other. We show that residential mobility over the life course tends to increase with the physical distance between the homes of parent and child. There are large differences in intergenerational proximity between the foreign-born and UK-born, and between ethnic groups. The determinants of intergenerational proximity from the parent's viewpoint are not identical to those from the child's viewpoint. Contrary to the findings of some earlier studies, intergenerational proximity, from the child's viewpoint, does not vary with the number of siblings. But from the parent's viewpoint, having more children is unambiguously associated with a higher probability of living close to at least one child. We end with a brief discussion of some possible implications of several long-term demographic trends in the UK for intergenerational proximity.     

中国老年人临终地点及影响因素研究

文章基于2008年、2011年、2014年北京大学中国老年人健康长寿影响因素追踪调查的死亡数据对中国老年人临终地点、影响因素及变化趋势进行研究。居住在城镇、年龄较小、社会经济地位高、拥有医疗保险、患有慢性疾病的老年人更可能"临终于医院";临终照护者为配偶、生活不能自理的老年人更可能"临终在家"。从变化趋势看,中国老年人"临终于医院"的比例有所上升,但仍以"临终在家"为主。研究认为其主要原因为80岁及以上高龄老年人占老年人口比例上升,城镇化发展背景下中国大多数老年人依然生活在农村,基层医疗卫生机构(如村卫生室)的发展增强了其临终医疗服务能力。在亲人的关心和注视下离开,在自己的家中接受临终关怀是多数老年人的临终心愿,也是临终的最佳选择。基于此,文章建议在中国老年人临终地点仍以"临终在家"为主的背景下,政府应出台相关政策,进一步增强基层医疗卫生机构的临终医疗服务能力,支持"家庭照护+上门医疗服务"的居家临终照护模式,这不仅能够满足多数老年人"临终在家"的意愿,减轻临终老年人的家庭经济负担,也可以在一定程度上缓解"临终于医院"所带来的医院床位资源紧缺。     

The Great Convergence: Gender and Unpaid Work in Europe and the United States

Over the past decades, men's and women's time use in industrialized nations has changed dramatically, suggesting a gender revolution. Women increased their time in paid work and reduced time in unpaid activities, while men increased their time in unpaid work, but not enough to compensate for women's retreat. We investigate developments regarding men's and women's unpaid work across Europe and the United States, using time diary data from the mid‐1980s and onward. We find evidence for gender convergence in unpaid work over time, but different trends for housework and childcare. Gender convergence in housework primarily resulted from women reducing their time, whereas childcare time increased for both sexes, resulting in convergence only where men increased more than did women. Decomposition analyses show that trends in housework and childcare are explained by changes in behavior rather than compositional changes in population characteristics. Though level differences in unpaid work persist, our findings regarding trends support gender convergence in that they are general across country contexts that vary regarding policy and social norms about gender, family, and work.     

Obesity, disease, and functional limitation in later life

Little is known about the effects of obesity late in life. Using data from the Longitudinal Study of Aging and the Assets and Health Dynamics of the Oldest Old Survey, this study finds an increased prevalence of obesity, over time, among those 70 and older. Obesity is related most strongly to limitations in activities of daily living (ADLs) for women and to activities related to mobility. One ADL, eating, has a negative association to obesity. Obesity is associated with an increased prevalence of arthritis, diabetes, and hypertension. These results are cross-sectional and are based on self-reports of height and weight; they must be interpreted cautiously.     

Gender Differences in Activity of Daily Living of the Elderly in Rural China: Evidence from Chaohu

ABSTRACT

Using data from a sample survey, “Well-being of the elderly in Anhui province, China,” this paper studies the effects of health, economic and family factors on the activities of daily living (ADLs) as measures of disability for elderly men and women. The objective is to explore reasons for gender differences in ADLs in rural China. Our results suggest that higher incidence rates of chronic diseases, lower cognitive ability, as well as heavier household and daily care burdens of females, are the main factors leading to a higher prevalence of ADL disability for the female elderly.     

中国老年人临终前 生活自理能力的衰退轨迹

本文以老年人为研究对象,以基本生活自理能力(ADL)为测量指标,使用"中国老年健康长寿影响因素跟踪调查"(CLHLS)数据,分析在1998-2014年期间去世的老年人群临终前的生活自理能力的变化轨迹。作者利用组基轨迹模型对男性和女性老年人的生活自理能力变化过程分别进行拟合,发现老年人在临终前的生活自理能力存在显著差异并归纳出三种变化轨迹:生活自理能力完好型、快速发展型和缓慢下降型。研究发现生命历程早期阶段的经历、所处的社会经济状况、年龄效应和队列效应都会对生活自理能力的衰退轨迹产生显著影响。增龄带来的生活自理能力下降使老年人临终前的失能风险及其持续时间增加,而较晚的出生队列在临终前出现长时间失能的可能性较低。在三类轨迹中,自理能力缓慢下降型轨迹受到各种因素的影响最为显著,而该类型的出现概率是影响失能老年人照料负担的主要因素,由此也证明了除去年龄效应与性别差异之外,由社会经济状况、健康行为习惯、生活环境等因素合力产生的健康保护作用将会在失能老年人照料负担增长过程中发挥主导作用。研究还发现老年女性在临终前会面临更高的失能风险和更长时间的失能存活期,其生活自理能力变化过程受到更多因素的影响。     

Resolving inconsistencies in trends in old-age disability: Report from a technical working group

In September 2002, a technical working group met to resolve previously published inconsistencies across national surveys in trends in activity limitations among the older population. The 12-person panel prepared estimates from five national data sets and investigated methodological sources of the inconsistencies among the population aged 70 and older from the early 1980s to 2001. Although the evidence was mixed for the 1980s and it is difficult to pinpoint when in the 1990s the decline began, during the mid- and late 1990s, the panel found consistent declines on the order of 1%-2.5% per year for two commonly used measures in the disability literature: difficulty with daily activities and help with daily activities. Mixed evidence was found for a third measure: the use of help or equipment with daily activities. The panel also found agreement across surveys that the proportion of older persons who receive help with bathing has declined at the same time as the proportion who use only equipment (but not personal care) to bathe has increased. In comparing findings across surveys, the panel found that the period, definition of disability, treatment of the institutionalized population, and age standardizing of results were important to consider. The implications of the findings for policy, national survey efforts, and further research are discussed.     

老年长期护理需求及其影响因素分析——基于苏皖两省调查的比较研究

随着我国人口的快速老龄化,老年人长期护理已经由过去家庭承担的事务演变成现在必须正视的社会问题。本文通过对安徽、江苏两省的调查,描述了老年人生活与健康状况以及长期护理需求的差异性,分析了老年长期护理需求意愿的影响因素。研究发现,地区、户口、教育程度、无子女、有退休金、洗澡有困难、半身不遂、女儿或女婿照料8个因素对老年长期护理需求具有显著的影响,但是相对于欠发达地区而言,这些因素对经济相对发达地区的老年人长期护理服务需求的影响度要小。在此分析基础上提出了推动与完善我国老年长期护理服务体系的一些政策建议。     

Unmet Needs for Assistance with ADLs and IADLs: A Measure of Healthy Life Expectancy

Measures of healthy life expectancy have beendeveloped over the last thirty years to evaluate thequality of life of an increasing life expectancy.These measures are usually accounting for prevalencerates of either disability or physical dependence inperforming everyday activities. Although they allowfor a better assessment of quality of life, they arenot reflecting the fact that a disabled person mightbe receiving adequate or inadequate assistance forthese activities. In a context of population aging,where our health care system will have to deal moreand more with chronic disease instead of acutedisease, it is imperative to develop a measure thatwill account for the adequacy of the assistanceprovided to the disabled elderly population. Usingdata from the 1986 Health and Activity LimitationSurvey, we are introducing a measure of healthy lifeexpectancy which will fill this gap. We present theconstruction of this measure of population health anddiscuss its usefulness in assessing policies at amacro level.
