Depression brings a great burden of disease to Brazil. This study investigates depression-free life expectancy (DFLE) between 1998 and 2013 in the country. We used data from Brazilian National Household Survey, National Health Survey and Life Tables provided by the Brazilian Institute of Geography and Statistics considering individuals 30 years and older. DFLE by race and sex was calculated using the Sullivan method. We observed improvements in DFLE over time, for all race/color groups. In general, men had a smaller share of years lived with depression when compared to women within the same race groups. Compared to whites, blacks/ browns and people of other races/colors had the highest DFLE for both men and women. White women had the lowest percentage of DFLE. Blacks displayed better estimates of DFLE and lower number of years living with depression than whites, despite the evidence of worse health outcomes depicted in the literature. Further research is needed to understand the lower depression prevalence found for blacks that reflects directly into a higher DFLE.

Unlike its short-term impact on consumption and income, forced migration is expected to deliver a permanent shock to the overall well-being of households, specifically children in the stage of infancy. Studies on the effect of forced migration on child cognitive well-being are few in number. Therefore, the present study is intended to examine the consequences of forced migration during infancy on child cognition at later age. We hypothesized that the effect of forced migration on child cognitive well-being can be mitigated by social support. The study used longitudinal data from three waves of the Young Lives Study (YLS) conducted in 2002, 2006–2007, and 2009 in the state of Andhra Pradesh, India. We used bivariate and multivariate regression models to analyze the consequences of forced migration in early childhood on the cognitive well-being in later childhood. The information on forced migration was collected in Wave 1 (at age 1), whereas the information on the cognitive well-being of the children was collected in Wave 3 (at age 8). Child cognitive well-being was measured using scores obtained by the children on the Peabody Picture Vocabulary Test (PPVT), math, Early Grade Reading Assessment (EGRA), and memory tests. The results of the bivariate analysis show that the mean PPVT, math, EGRA, and memory scores obtained by children from the migrated households were lower than those obtained by children from the non-migrated households. Results of the multivariate linear regression models also show that children from the migrated households were statistically less likely to achieve higher scores on math (coefficient: -2.008, 95% C.I.-3.108, -0.908), EGRA (coefficient: -0.746, 95% C.I.-1.366, -0.126), and memory (coefficient: -0.503, 95% C.I. -0.834, -0.173) as compared to children from the non-migrated households. Our findings also indicate that the effect of forced migration on child cognitive well-being was not mitigated by social support. Findings of this study conclude that forced migration during infancy has a significant effect on child cognitive well-being at later age. Therefore, interventions should be made, paying attention to the most vulnerable children who were displaced during critical development ages.

The study analyzed infant mortality and its risk factors in South Africa. It aimed to examine infant mortality in the country by taking into account the hierarchical nature of the problem and investigate the with-in country variation in modeling. In addition to the usual individual level risk factors of infant mortality, living standard, mother’s education, and income inequality were defined at municipal level, while HIV prevalence was fixed at province level. A multilevel logistic regression model was then fitted with Bayesian MCMC parameter estimation procedure using the 2011 South African census data. Most of the demographic and socioeconomic variables identified at individual level were found significant. More remarkably, the result indicated that communities with better living standard and women's education were associated with lower infant mortality rates, while higher income inequality and HIV prevalence in the communities were associated higher levels of infant mortality. The changes in infants’ odds of death were estimated to be 26%, -21%, 13% and 8% respectively for HIV, women’s education, income inequality and level of the living standard. In addition, unobservable municipal and province level random effects significantly affected the level of infant mortality rates.

We analyze the effects of household structure on education in Cambodia. Consistent evidence documents that residence with both biological parents benefits children’s education in Western countries. Elsewhere, the issue is gaining more attention with the growing number of “left-behind children” due to adult migration and, possibly, changes in family behavior. The extant record is both thinner and more contrasted, however. Controlling for the presence of grandparents and some household characteristics, we find children residing with both biological parents are more likely to be enrolled in school, in the appropriate grade for their age, and literate than those living with only one parent. The effect sizes appear comparable to those in most Western countries, but the effects shrink or even disappear when grandparents are present. The results for children not residing with either parent are mixed, possibly resulting from negative effects for some children and positive selection for some others.

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.

    Text

    The text of the manuscript should be in Microsoft Word or Latex. The length of the manuscript cannot be more than 50,000 characters (inclusive of spaces), or approximately 7,000 words.

    Figures

    Authors should include all figures into the manuscript and submit it as one file. Figures include photographs, scanned images, graphs, charts and schematic diagrams. Figures submitted should avoid unnecessary decorative effects (e.g. 3D graphs), as well as should be minimally processed (e.g. changes in brightness and contrast applied uniformly for the entire figure). It should also be set against a white background. Please remember to label all figures (e.g. axis, etc.) and add captions below the figure, as required. These captions should be numbered (e.g. Figure 1Figure 2, etc.) in boldface. All figures must have a brief title (also known as caption) that describes the entire figure without citing specific panels, followed by a legend, defined as description of each panel. Please identify each panel with uppercase letters in parenthesis (e.g. (A), (B), (C), etc.)

    The preferred file formats for any separately submitted figure(s) are TIFF or JPEG. All figures should be legible in print form and of optimal resolution. Optimal resolutions preferred are 300 dots per inch (dpi) for RBG coloured, 600 dpi for greyscale and 1,200 dpi for line art. Although there are no file-size limitation imposed, authors are highly encouraged to compress their figures to an ideal size without unduly affecting the legibility and resolution of figures. This will also speed up the process of uploading in the submission system, if necessary.

    The Editor-in-Chief and Publisher reserve the right to request from author(s) the high-resolution files and unprocessed data and metadata files, should the need arise at any point after manuscript submission for reasons such as production, evaluation or other purposes. The file name should allow for ease in identifying the associated manuscript submitted.

    Tables, Lists and Equations

    Tables created using the Microsoft Word table function are preferred. The tables should be numbered (e.g., Table 1, Table 2, etc.) and should include a title at the top. Titles and footnotes/legends should be concise. These must be submitted together with the manuscript. Likewise, lists and equations should be properly aligned and their meaning clear to readers. For listing things within the main body of the manuscript, please use roman numbers in parenthesis (e.g., (i), (ii), (iii), (iv), etc.). 

    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.

    Examples:

    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. The method is proved to be valid in the literature (Chandler and Tsai, 2001).

    Three or more authors

    (1) In leading a sentence, 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. In 2014 Dickson et al. noted that such initiatives have far-bearing effects.

    (2) In the end of sentence, use all three last names with "and" before the last author's name if there are only three authors; and use all three last names followed by italicized et al. and the year if there are four or more authors. Examples: This was further emphasized and subsequently widely accepted (Dickson, Andersen, and Thompson, 2014; Gates, White, Chen et al., 2016).

    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)

    References

    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.

Call for Guest Editors and Special Issues on Population Dynamics and Challenges in Asia

 

We would like to launch a series of special issues related to population dynamics and challenges in Asia.

Asia is the most populous continent in the world with great diversities in population growth and socioeconomic development. Many Asian countries have been witnessing or will witness a faster pace of urbanization, population aging than most today's developed countries; and most of them will likely grow old before they grow rich. However, the poor health care system, inadequate pension coverage, poor nutrition, poor facilities and infrastructure, and poor living environments, will impose tremendous challenges for Asian countries. In order to provide some scholarly thoughts for helping to adequately address these challenges, the International Journal of Population Studies wishes to launch for a series of special issues. These special issues will focus on, but not limited to, the following themes:

(1) Population dynamics

(2) Data quality in population and health surveys

(3) Changes of family support system

(4) Successful aging

(5) Aging-friendly city

(6) Pension system reforms

(7) Urbanization, climate change, and health

(8) Economics of aging

(9) Population aging and healthcare challenges

(10) Reproductive health

(11) Child nutrition, health and development

(12) Gender equity and women’s empowerment

(13) Labor force migration in Asian countries and consequences

(14) Youth and development

(15) Low fertility and socioeconomic development

(16) Population growth and sustainable development goals

(17) Dynamics and projections of family household

(18) Business of aging

(19) Marriage matching

(20) Vulnerable populations

If any researcher is interested in taking the lead of a special issue or wishes to propose a new special issue, please send your request to editorial@whioce.com for more information. We especially welcome multi-culture or cross-nation comparative studies.
