A simulation model has been developed, which looks at the future state of functional limitations and provision of long-term care from the individual’s point of view and compares the prospects of Japanese and Swedish old persons. The model calculates the distribution on level of functional limitations combined with level of long-term care (LTC) for a 78-year-old man or woman after 3, 6, 9, 12 and 15 years given the initial state expressed in those terms.
Longitudinal data for the model has been taken from the Nihon University Japanese Longitudinal Study of Aging (NUJLSOA) study, two waves three years apart, and the Swedish National Study of Aging and Care (SNAC) study, baseline and three-year follow up. Transition probabilities are calculated by relating individual states between waves. Changes over time are then calculated in the model by matrix multiplication using the Markov assumption.
The results are in most respects similar for Japan and Sweden. A difference is that institutional care in Sweden is a much more definite stage reflecting differences in end-of-life care policy. Future state and mortality depends to a great degree on the initial state, both in terms of dependency and level of LTC. Thus, 78-year-old people who have no functional dependency and no LTC have a much higher probability of surviving the coming 10–15 years than people of the same age who already are dependent and in need of LTC services. Not a few of the initially independent 78-year-old persons will retain that state even after 15 years. However, the effect of the initial state seems to decrease over time.

We examined whether exposure to urban environments was linked with mortality in a longitudinal survey dataset of nearly 28,000 Chinese adults who were 65 years of age or older in the years 2002–2014. Urban life exposure was measured by residential status at birth, current residential status, and urban-related primary lifetime occupation, which generated eight different categories of urban life exposure: no exposure, mid-life-only exposure, late-life-only exposure, mid-late-life exposure, early-life-only exposure, early-mid-life exposure, early- & late-life exposure, and full life exposure. We also included a measure of migration, whether the respondent lived in the same county/city at birth and at first interview, to further classify these eight categories. Overall, we found that when demographics were controlled for, compared to those with no urban life exposure and no migration, mortality risk was lower for older adults with mid-late life exposure with or without migration and for older adults with full-life exposure with migration; mortality risk was higher for older adults with early-life-only exposure. Once socioeconomic status, family/social support, health behaviors, and baseline health were simultaneously controlled for, only the higher mortality risk for older adults with early-life-only exposure was still significant. Our findings provided valuable information about how urban life exposure at different life stages was associated with elderly mortality in China.

In Bangladesh, although some research on health expectancy exists, life expectancies with and without hypertension (HTN) have never been computed. We examined gender differences in the prevalence of hypertension and Hypertension-Free Life Expectancy (HFLE) in Bangladesh. We used data from a nationally representative survey of 7,864 people aged 35 and older. We classified an individual as having HTN if s/he had blood pressure levels ≥140 mmHg systolic blood pressure or ≥90 mmHg diastolic blood pressure, or s/he was at the time on antihypertensive medication. The Sullivan method was employed to compute HFLE. We found that women have HTN in significantly higher percentages (32% of women vs. 19% of men), and the prevalence of HTN increases as age increases for both men and women. Among individuals with HTN, individuals unaware of HTN make up the largest group, followed by those with uncontrolled HTN, controlled HTN, and those who are aware of HTN but not in treatment. Compared with men, women could expect shorter HFLE at all ages, in terms of both number and proportion of years. To increase HFLE as well as quality of life and to prevent and control HTN in general and unawareness of HTN and uncontrolled HTN in particular, special care and attention should be given to women and older adults. The findings shed important light on the role of HTN in lowering the quality of life in Bangladesh.

This paper investigates the coverage of public pension programs in Latin America and discusses the relation between economic development, the existence of public pension programs, and elderly labor force participation. The paper presents stylized facts about the labor force by age and the connection between economic development and labor supply using aggregated data from 23 Latin American countries. The second part of the paper uses regression models to investigate the effects of economic development and social security system on the labor force participation of the older adults in 23 Latin American countries over the period 1990–2010. The results show that in lower income Latin American countries, most men remained in the labor force until age 65 or beyond and that with economic development and related changes, the labor force participation of older men, even those aged 55–59, starts to decline. Overall, the paper provides some insight on the evolution of labor supply patterns in less developed economies with rising income, changes in population age structure, shifts in occupational composition, and development in public pension programs.

Using data on disability vignettes from representative surveys in the U.S. and seven European countries, we conduct a comparative analysis of disability policies and public views on work limitations. We hypothesize that program characteristics are related to individuals’ perceptions about work limitations. Looking at how respondents across countries characterize identical disability vignettes, we find evidence that disability policy dimensions such as policy coverage, medical assessment, and vocational assessment strongly predict disability perceptions. We illustrate the results in a series of counterfactual policy simulations. Our findings have implications for policy design and delivery. The anchoring vignette approach may also be useful in a wide range of comparative policy studies.

With the rapid aging of the Chinese population, growing attention has been given to old-age support. Widowed older adults constitute a particularly vulnerable population because the loss of a spouse can lead to financial hardships and emotional distress. We used data from the 2002 Chinese Longitudinal Healthy Longevity Survey to examine multiple dimensions of old-age support among a nationwide sample of widowed old adults ages 65 and older (N = 10,511). The results show that Chinese widows and widowers rely heavily on their adult children, particularly sons and daughters-in-law, for financial, instrumental, and emotional support. Widowed older adults’ needs and the number of children are the most significant predictors of old-age support. Widowed older adults with multiple marriages have a lower likelihood of receiving financial assistance, sick care, and emotional support from their children compared to their counterparts who have married only once. There appears to be same-gender preference in adult children’s care for their widowed parents with disabilities.

Multilevel modelling techniques such as random models or fixed effect are increasingly used in social sciences and demography to both account for clustering within higher level aggregations and evaluate the interaction between individual and contextual information. While this is justifiable in some studies, the extension of multilevel models to national level analysis — and particularly cross-national comparative analysis — is problematic and can hamper the understanding of the interplay between individual and country level characteristics. This paper proposes an alternative approach, which allocates countries to classes based on economic, labour market and policy characteristics. Classes influence the profiles of three key demographic behaviours at a sub-national level: marriage, cohabitation and first birth timing. Woman level data are drawn from a subset of the Harmonized Histories dataset, and national level information from the GGP contextual database. In this example, three country classes are extracted reflecting two Western patterns and an Eastern pattern, divided approximately along the Hajnal line. While Western countries tend to exhibit higher levels of family allowances albeit accounting for a lower share of spending which is associated with lower marriage and later fertility, Eastern countries generally show a higher share of spending but at lower absolute levels with lower cohabitation rates and early fertility.

This study examined the possible underestimation and age-trajectories of mortality at oldest-old ages in China’s 2000 and 2010 censuses. By linking logit-transformed conditional probabilities of dying from 13 countries with the highest data quality in the world, this study found that many Chinese provinces had underestimations of mortality at oldest-old ages when a relatively lenient criterion was applied. When a relatively strict criterion was applied, most provinces had a 30% or more underestimation in the probability of dying. We also investigated age trajectories of death rates after age 80 in these two censuses by applying the Kannisto model. Results showed that the age trajectories were distorted in most provinces after age 95. Overall, eastern-coastal provinces had higher data quality — in terms of low underestimation rates and less distorted age trajectories — whereas western China had provinces with problematic data. Females had greater rates of underestimation yet less distorted age-trajectories than males; and the 2010 census had greater rates of underestimation yet less distorted age-trajectories than the 2000 census. We conclude that appropriate adjustments with simultaneous applications of the Kannisto model are needed for direct estimates of mortality at oldest-old ages in the 2000 and 2010 censuses for China and for its provinces.

Focusing on Asian-American immigrants in the National Latino and Asian American Study, this work examines (1) whether immigration-related stressors are associated with 12-month depressive disorder and suicidal ideation, and (2) how individual religious involvement moderates the associations. Findings from regression analyses reveal that limited English proficiency increases the risk of both 12-month depressive disorder and suicidal ideation. No significant differences in 12-month depressive disorder and suicidal ideation are found by age at immigration. Most importantly, religious coping — frequently seeking comfort from religion — buffers the negative effects of limited English proficiency on suicidal ideation. Our findings suggest the importance of individual religious involvement in helping Asian-American immigrants cope with stress associated with immigration. Mental health professionals may need to integrate religious coping mechanisms into the clinical setting to offer more effective treatments that are sensitive to individuals’ religious and spiritual needs.

The objective of this study was to estimate life expectancy with and without a specific chronic disease among the Brazilian elderly population, by sex and socioeconomic factors, for the years 1998 and 2008. Life expectancy with and without hypertension, diabetes, bronchitis/asthma, and heart disease were calculated using the Sullivan method and prevalence estimates from data collected in the two years through the Brazilian National Household Survey (PNAD). Hypertension was the chronic disease with the largest effect on life expectancy. Among socioeconomic determinants, education proved more relevant than income. Having more years of education increased the average healthy time. Socioeconomic inequality negatively affected the health of women more than men. Despite the social changes in Brazil in recent decades with a reduction in inequality and poverty, the effect of socioeconomic inequality in the country on the health status of the elderly remains evident.

    Supplementary information

    This section is optional and contains all materials and figures that have been excluded from the entire manuscript. These information are relevant to the manuscript but remain non-essential to readers’ understanding of the manuscript’s main content. All supplementary information should be submitted as a separate file in Step 4 during submission. Please ensure the names of such files contain ‘suppl. info’. Videos may be included in this section.

    In-text citations

    Reference citations in the text should be done using the author-date method in which the author’s surname and the year published are included in the text. If the reference has no known year of publication, use ‘n.d.’ (without the quotation marks). The citation style depends on the number of authors for the reference.


    One author 

    Niemi (2011) illustrated some scenarios to prove this. The theory governs civil society (Niemi, 2011) and social behaviour. In 2011 Niemi described the theory in detail.

    Two authors

    Always use both names. Examples:

    Chandler and Tsai (2001) analyzed data from several reports. This theory was further supported by Chandler and Tsai (2001). In 2001 Chandra and Tsai proposed a possible mitigation measure.

    Three or more authors

    Use first author’s name, followed by italicized et al. and the year. Examples:

    Dickson et al. (2014) brought up some points to support such an argument. This was further emphasized (Dickson et al, 2014) and subsequently widely accepted. In 2014 Dickson et al. noted that such initiatives have far-bearing effects.

    Personal communications and unpublished works can only be used in the main text of the submission and are not to be placed in the Reference section. Authors are advised to limit such usage to the minimum. They should also be easily identifiable by stating the authors and year of such unpublished works or personal communications and the word ‘Unpublished’ in parenthesis.

    E.g. (Smith J, 2000, Unpublished)


    This section is compulsory and should be placed at the end of all manuscripts. The list of references should only include works that are cited in the text and that have been published or accepted for publication. 

    The references in reference list should be arranged in alphabetical order of the first author’s surname. Authors referenced should be listed with their surname followed by their initials. All references should also appear as an in-text citation. References should follow the following pattern: Author(s) followed by year of publication, title of publication, full journal name in italics, volume number, issue number in parenthesis and, lastly, page range. If the referred article has more than three authors, list only the first three authors and abbreviate the remaining authors to italicized ‘et al.’ (meaning: "and others"). If the DOI is available, please include it after the page range.
