RESUMO
Research on religiosity and health has generally focussed on the United States, and outcomes of health or mortality but not both. Using the European Values Survey 2008, we examined cross-sectional associations between four dimensions of religiosity/spirituality: attendance, private prayer, importance of religion, belief in God; and healthy life expectancy (HLE) based on self-reported health across 47 European countries (n = 65,303 individuals). Greater levels of private prayer, importance of religion and belief in God, at a country level, were associated with lower HLE at age 20, after adjustment for confounders, but only in women. The findings may explain HLE inequalities between European countries.

Objectives: Eight years of panel data are used to investigate the association between three dimensions of religiosity and total and disability-free life expectancy (TLE/DFLE) in Taiwan. Method: Data come from the 1999 "Taiwan Longitudinal Study on Aging" (TLSA; N = 4,440; Age 55+). Dimensions of religiosity are public, private, belief, and coping. Mortality is linked to a national database. Disability is activities of daily living (ADLs). TLE/DFLE estimates use the Stochastic Population Analysis for Complex Events (SPACE) software. Results: Those who engage in public and private religiosity live longer and more years disability-free than others, but proportion of life disability-free does not differ across levels of religiosity. Coping is less associated with TLE and DFLE. Coping however associates with more years disabled among men. Findings are robust to model specifications. Discussion: The way in which religiosity associates with health depends upon the definition. When it does associate, religiosity increases TLE and DFLE proportionately.

BACKGROUND: The rise in the number and earlier age of onset of obese persons has raised critical concerns about consequences of obesity; however, recent evidence suggests that the impact of obesity on health outcomes may have changed. This study aims to assess the change of the impact of obesity on active life expectancy among Americans aged 70 years and older over almost two decades, 1993-1998 to 2010-2014. METHODS: For each period, we use three waves of data from the Health and Retirement Study to estimate age-specific transition probabilities between health states. The average number of years active and disabled is calculated with Interpolated Markov Chain software based on estimated transition probabilities. RESULTS: Overall obesity and severe obesity increased markedly over time yet active life expectancy expanded for all individuals and the increases are greater among the obese and women. Increases in total and active life expectancy occurred because of the changing association of obesity with disability and mortality. CONCLUSIONS: Individuals at age 70 years in the later period in each weight group could expect to live a smaller proportion of remaining life with activities of daily living disability than those in the earlier period. High levels of obesity continue to have significant adverse effects on the quality of life. The increasing prevalence of severe obesity and the growing number of older persons may result in substantial additional health care needs and costs. Continued effort to improve cardiovascular health is required to control the burden of obesity in later life in an era of rising obesity.

BACKGROUND: The Global Activity Limitation Indicator (GALI) is a single-item measure of functional decline, it is widely used in Europe but it has never been validated in an Asian population. The aim of this study was to validate the GALI in a sample of older Taiwanese people and to explore whether it captured not only physical but also psychological limitations. METHODS: Data for 4961 individuals (mean age, 62.4 ± 9.4 years; 47.2% men) were obtained from a national representative refresh cohort of the 8th wave of the Taiwan Longitudinal Survey on Aging. Logistic regression analysis was used to examine associations among the GALI, activities of daily living (ADLs) and instrumental activities of daily living (IADLs) and to explore whether depressive symptoms (measured by the Center for Epidemiologic Studies Depression Scale, CES-D) could be an indicator of reporting limitations on the GALI. RESULTS: Responding to the GALI, 21.7% of the sample described themselves as 'limited.' In logistic regression, the GALI response was significantly associated with those who reported one or more ADL difficulties (odds ratio [OR] = 35.89, 95% confidence interval [CI] 21.10, 61.03) and IADL difficulties (OR = 13.37, 95%CI 10.09, 17.71), respectively. Furthermore, those with more depressive symptoms were more likely to report they were 'limited' on the GALI. CONCLUSIONS: These findings provided evidence that the GALI is a valid tool to assess general limitations in an Asian population. Furthermore, it captured psychological limitations to some extent. There were variations between Taiwan and European countries (as has been previously reported between European countries). The reporting level in the GALI by the Taiwan population was comparatively lower than that in European countries, highlighting the need to embrace cultural differences and to use caution when comparing GALI results across countries.

Compared to the large volume of research focused on mortality differentials within Japan, relatively little is known about regional variations in health expectancy, particularly among older people. This article has two interrelated objectives. The first objective is to estimate prefecture-specific disability-free life expectancy (DFLE) at 65 years of age in 2010. DFLE at 65 by gender and prefecture was computed using the Sullivan method, which was applied to prefecture-specific life tables and prevalence of disability from Kokumin Seikatsu Kiso Chosa (Comprehensive Survey of Living Conditions) of 2010. The second objective is to investigate macro-level factors associated with DFLE at 65 across 47 Japanese prefectures. Our results indicate regional disparities in DFLE at older ages. Importantly, we note close relationships between a prefecture's wealth, labor, and welfare characteristics and DFLE at 65. Income per capita, the proportion of workers older than 65, and welfare expenditures are positively related to DFLE, whereas unemployment and long-term care insurance expenditures per-capita are inversely associated with DFLE for both genders. The proportion of older adults relying on public assistance is negatively related only to women's DFLE. These results suggest that narrowing socioeconomic disparities may contribute to the health of Japanese elders. Reducing regional health disparities therefore requires policy makers to take into account the broader socioeconomic conditions of each prefecture.
RESUMO
Population aging is expected to increase long-term care (LTC) costs in both Japan and Sweden. This study projected LTC costs for 2010 through 2040 for different assumptions of population change, LTC need by age group and gender, and LTC provided per level of need and cost in Japan and Sweden. Population data were taken from the official national forecasts. Needs projections were based on epidemiological data from the Nihon University Japanese Longitudinal Study of Aging and the Swedish Survey of Living Conditions. Data on LTC provision by need and cost were taken from nine Japanese municipalities collected by assessments in the LTC insurance system and from surveys in eight Swedish municipalities. Total initial costs were calibrated to official national figures. Two projections based on two different scenarios were made for each country from 2010 to 2040. The first scenario assumed a constant level of need for LTC by age group and gender, and the other assumed a continuation of the present LTC need trends until 2025. For Japan, this resulted in a projected cost increase of 93% for the one and 80% for the other; for Sweden it was 52% and 24%, respectively. The results reflected differences in population aging and health development.

BACKGROUND: Disability among older adults is a public health concern. To date there are no in-depth and comprehensive analyses on older adults' disabilities in Bangladesh. This study investigated gender differences in the prevalence of disability and the socio-demographic factors associated with disability among older adults in Bangladesh. METHODS: This research used a sample of 4176 elderly males and females aged 60 years and over from a nationally representative data set- Bangladesh's 2010 Household Income and Expenditure Survey. The study used both household level and individual level data and applied a wealth index, which was constructed based on household assets using principal component analysis. The Washington Group's short set of questions on disability were used to measure disability. Chi-square tests and ordinal logistic regression models were fit. RESULTS: Forty-two percent of older had some form of functional disability, including 5% of elderly with severe/extreme functional disability. Seven percent of older adults had a self-care disability, including 3% of elderly with a severe/extreme form of self-care disability. Elderly females suffered from all the studied disabilities, including functional and self-care disabilities in higher percentages, and had higher odds ratios of having both functional disability and self-care disability compared to elderly males. The study also identified some significant factors affecting functional disability and self-care disability, namely age, having a chronic condition, wealth status and place of residence, including divisional differences. CONCLUSIONS: Programs aimed at reducing functional disability among seniors, particularly elderly females, should be granted the highest priority in Bangladesh.

OBJECTIVES: The second phase of Healthy Japan 21 seeks to increase disability-free life expectancy (DFLE) more than life expectancy (LE) between 2013 and 2022. In the face of the rising incidence of disability, the feasibility of achieving this goal remains unclear. METHODS: We examine changes in DFLE at birth between 2000 and 2010 across 47 prefectures, with particular attention given to changes in the absolute number of years and in the proportion of disability-free life years. RESULTS: Although LE increased across all prefectures, there is a variation in DFLE. While the number of disability-free life years increased in many parts of the country, some prefectures had decreases in DFLE. Downturns become particularly evident when DFLE is interpreted in relative terms. The proportion of life spent without disability declined in the majority of prefectures. CONCLUSIONS: Results from subnational level analyses suggest that the rate of increase in DFLE lagged behind that in LE across Japanese prefectures during the past decade. More policy attention should be devoted to health-promotion initiatives at the prefecture level to achieve the nationwide health agenda.

AIM: The aim of the present study was to compute total life expectancy (TLE), active life expectancy (ALE) and inactive life expectancy among older Singaporeans by gender, education and ethnicity. METHODS: Data from a longitudinal survey of older Singaporeans were used. No difficulty in carrying out activities of daily living or instrumental activities of daily living was considered as "active." Transition probabilities across health states (active/inactive/dead) were assessed to develop multistate life tables, which estimated TLE, ALE and inactive life expectancy. RESULTS: At age 60 years, women, versus men, had significantly higher TLE (25.9, 95% confidence interval [CI] 24.0-27.8 vs 21.6, 95% CI 20.1-23.1), but similar ALE (18.1, 95% CI 17.0-19.2 vs 18.9, 95% CI 17.7-20.2). Those with high (secondary or higher), versus low (primary or less), education had significantly higher TLE (28.5, 95% CI 25.0-32.0 vs 22.5, 95% CI 21.1-23.9) and ALE (23.5, 95% CI 21.2-25.7 vs 17.1, 95% CI 16.1-18.0) at age 60 years. Those of Chinese, versus non-Chinese, ethnicity had significantly higher ALE at age 60 years (19.4, 95% CI 18.4-20.3 vs 15.0, 95% CI 13.4-16.7). CONCLUSION: Unlike Western nations, there was no gender difference in ALE among older adults in Singapore. However, difference in ALE by education among older Singaporeans was similar to that observed in Western societies. Policies focusing specifically on improving women's health at all ages, in addition to policies that increase population education levels, are promising approaches to improving ALE. Recognizing ethnic differences in ALE will help target policies that increase ALE in multicultural societies.

A large literature suggests that active social participation contributes to the well-being of older people. Japan provides a compelling context to test this hypothesis due to its rapidly growing elderly population and the phenomenal health of the population. Using the Nihon University Japanese Longitudinal Study of Aging, this study examines how social participation, measured by group membership, is related to the risk of overall mortality among Japanese elders aged 65 and older. Results from Cox proportional hazards models show that group affiliation confers advantages against mortality risk, even after controlling for sociodemographic characteristics, physical health measures, and family relationship variables. In particular, activities geared more toward self-development, such as postretirement employment and lifelong learning, are strongly associated with lower levels of mortality. Findings suggest that continued social participation at advanced ages produces positive health consequences, highlighting the importance of active aging in achieving successful aging in the Japanese context.

OBJECTIVE: To investigate inequality in disability in Bangladesh. METHODS: The study used both household level and individual level data from a large nationally representative data set, Bangladesh's Household Income and Expenditure Survey-2010. Principal component analysis was used to construct a wealth index based on household assets from household level data. Then, using data from 49,809 individuals aged 5 years and over, chi-square tests and logistic regression were performed to test the association between wealth level and disability. FINDINGS: Women and older people are significantly more likely to report having disabilities than men and younger people. For middle and rich families, respectively, there is a 14 percent lower likelihood of reporting disabilities than for poor families. Changes in the probability of having disabilities are linear with increasing wealth. In addition, the study identifies some significant factors affecting disability, namely, age, sex, education, marital status, and place of residence including divisional differences. CONCLUSION: In Bangladesh, worse health among the poor argues for policies prioritizing this group while at the same time giving special attention to women and the elderly.

This response letter addresses two points raised by le Bourg when discussing our previous paper entitled "Exploring the impact of climate on human longevity". First, the arguments explaining the accuracy of the numbers of centenarian in Okinawa are developed, and second the composition and healthfulness of the traditional Okinawan diet are described as well as the changes in dietary pattern and their impact on longevity.

BACKGROUND: Self-rated health is commonly employed in research studies that seek to assess the health status of older individuals. Perceptions of health are, however, influenced by individual and societal level factors that may differ within and between countries. This study investigates levels of self-rated health (SRH) and correlates of SRH among older adults in Australia, United States of America (USA), Japan and South Korea. METHODS: Cross-sectional data were drawn from large surveys of older respondents (≥ 65 years) in Australia (n = 7,355), USA (n = 10,358), Japan (n = 3,541) and South Korea (n = 3,971), collected between 2000 and 2006. Harmonized variables were developed to represent socioeconomic, lifestyle and health indicators. We then assessed whether these variables, and their potentially different impact in different countries, could account for cross-national differences in levels of SRH. RESULTS: SRH differed significantly between countries, with older Koreans reporting much poorer health than those in the other three nations. This was not the result of biases in response patterns (for example central versus extreme tendency). Health-related correlates of SRH were similar across countries; those with more medical conditions, functional limitations or poor mental health gave poorer ratings. After accounting for the differential impact of determinants in different national contexts, Australians reported better SRH than other nations. CONCLUSIONS: We conclude that when examining correlates of SRH, the similarities are greater than the differences between countries. There are however differences in levels of SRH which are not fully accounted for by the health correlates. Broad generalizations about styles of responding are not helpful for understanding these differences, which appear to be country, and possibly cohort specific. When using SRH to characterize the health status of older people, it is important to consider earlier life experiences of cohorts as well as national and individual factors in later life. Further research is required to understand the complex societal influences on perceptions of health.

The purpose of this study was to examine the impact of physical geographic factors and climate conditions on human longevity. The centenarian rate (CR) in 2005 was computed for Japan's 47 prefectures, whose geography and climate vary greatly. Several pathways, such as excess winter mortality, land use and agricultural production, possibly linking physical and climate factors with extreme longevity, were explored. The probability of becoming a centenarian varies significantly among the Japanese prefectures. In particular, the computation of CR(70) demonstrated that the actual probability for individuals 70 years old in 1975 of becoming centenarians in 2005 was 3 times higher, on average, in Okinawa, both for males and females, than in Japan as a whole. About three quarters of the variance in CR(70) for females and half for males is explained by the physical environment and land use, even when variations in the level of socio-economic status between prefectures are controlled. Our analysis highlighted two features which might have played an important role in the longevity observed in Okinawa. First, there is virtually no winter in Okinawa. For instance, the mean winter temperature observed in 2005 was 17.2°C. Second, today, there is almost no rice production in Okinawa compared to other parts of Japan. In the past, however, production was higher in Okinawa. If we consider that long term effects of harsh winters can contribute to the mortality differential in old age and if we consider that food availability in the first part of the 20th century was mainly dependent on local production, early 20th century birth cohorts in Okinawa clearly had different experiences in terms of winter conditions and in terms of food availability compared to their counterparts in other parts of Japan. This work confirms the impact of climate conditions on human longevity, but it fails to demonstrate a strong association between longevity and mountainous regions and/or air quality.

PURPOSE: The purpose of this article is to estimate the effect of obesity on both the length of life and length of nondisabled life for older Americans. DESIGN AND METHODS: Using data from the first 3 waves of the Asset and Health Dynamics Among the Oldest Old (AHEAD) survey, this article develops estimates of total, active, and disabled life expectancy for obese and nonobese older men and women. We used the Interpolation of Markov Chains (IMaCh) method to estimate the average number of years obese and nonobese older persons can expect to live with and without activity of daily living (ADL) disability. RESULTS: Our findings indicate that obesity has little effect on life expectancy in adults aged 70 years and older. However, the obese are more likely to become disabled. This means that obese older adults live both more years and a higher proportion of their remaining lives disabled. IMPLICATIONS: The lack of significant differences in life expectancy by obesity status among the old suggests that obesity-related death is less of a concern than disability in this age range. Given steady increases in obesity among Americans at all ages, future disability rates may be higher than anticipated among older U.S. adults. In order to reduce disability among future cohorts of older adults, more research is needed on the causes and treatment of obesity and evaluations done on interventions to accomplish and maintain weight loss.
