The Interaction of Racial-Ethnic and Economic Concentration and its Association with Premature Mortality in U.S. Neighborhoods
A Global Analysis of Within-Country Health Inequalities
Results of this study suggest that infant mortality and life expectancy are critical factors in shaping countries' health inequalities. Sustained improvements in countries with high infant mortality may have the potential to further reduce inequality at a global scale. In the US, comparatively slow progress on health inequality underscores its salience in national health policy discussions
Social normative origins of the taboo gap and implications for adolescent risk for HIV infection in Zambia
Zambian Demographic and Health Survey data reveal that increased discordance between professed attitudes and measures of behaviour regarding premarital sex among adults is strongly associated with increased risk of HIV in adolescents, particularly girls. We hypothesised that this was due to the reluctance to talk about premarital sex, resulting in a situation we call the "taboo gap" where sexual behaviour is a forbidden topic and adolescents feel…
Innovative methods to analyse the impact of gender norms on adolescent health using global health survey data
Men’s Attitude Towards Contraception and Sexuality, Women’s Empowerment, and Demand Satisfied for Family Planning in India
Whilst the prevalence of unmet need and contraceptive use remained unchanged for 10 years (between 2005-2015) in India, gender restrictive norms and power imbalances also have persisted, preventing married women from meeting their family planning desires. Data for this study are from the 2015-6 National Family Household Survey, which contains information on fertility preferences and family planning for women in reproductive age. As a proxy for me…
Technological Progress and Health Convergence
Throughout history, technological progress has transformed population health, but the distributional effects of these gains are unclear. New substitutes for older, more expensive health technologies can produce convergence in population health outcomes but may also be prone to elite capture and thus divergence. We study the case of penicillin using detailed historical mortality statistics and exploiting its abruptly timed introduction in Italy af…
Association of collective attitudes and contraceptive practice in nine sub-Saharan African countries
BACKGROUND: There is ample evidence that gender norms affect contraceptive practice; however, data are mostly qualitative with limited geographical scope. We investigated that association quantitatively using collective community-level attitudes towards premarital sex and wife-beating as proxies for gender norms. METHODS: Data came from nationally representative Demographic and Health Surveys (2005-2009) for women of reproductive age (15-49 years…

Distinct clusters of stunted children in India
Childhood stunting is often conceptualised as a singular concept (i.e., stunted or not), and such an approach implies similarity in the experiences of children who are stunted. Furthermore, risk factors for stunting are often treated in isolation, and limited research has examined how multiple risk factors interact together. Our aim was to examine whether there are subgroups among stunted children, and if parental characteristics influence the li…
Trends in inequalities in child stunting in South Asia
We analysed socio-economic inequalities in stunting in South Asia and investigated disparities associated with factors at the individual, caregiver, and household levels (poor dietary diversity, low maternal education, and household poverty). We used time-series analysis of data from 55,459 children ages 6-23 months from Demographic and Health Surveys in Bangladesh, India, Nepal, and Pakistan (1991-2014). Logistic regression models, adjusted for …
Relative importance of 13 correlates of child stunting in South Asia
Rethinking policy perspectives on childhood stunting
Stunting and chronic undernutrition among children in South Asia remain a major unresolved global health issue. There are compelling intrinsic and moral reasons to ensure that children attain their optimal growth potential facilitated via promotion of healthy living conditions. Investments in efforts to ensure that children's growth is not faltered also have substantial instrumental benefits in terms of cognitive and economic development. Using t…
Community-Based Health Financing and Child Stunting in Rural Rwanda
Objectives. We analyzed the likelihood of rural children (aged 6–24 months) being stunted according to whether they were enrolled in Mutuelles, a community-based health-financing program providing health insurance to rural populations and granting them access to health care, including nutrition services. Methods. We retrieved health facility data from the District Health System Strengthening Tool and calculated the percentage of rural health cent…
Work–Family Trajectories and the Higher Cardiovascular Risk of American Women Relative to Women in 13 European Countries
Objectives. To investigate whether less-healthy work–family life histories contribute to the higher cardiovascular disease prevalence in older American compared with European women. Methods. We used sequence analysis to identify distinct work–family typologies for women born between 1935 and 1956 in the United States and 13 European countries. Data came from the US Health and Retirement Study (1992–2006) and the Survey of Health, Aging, and Retir…
The Effect of Education on the Demographic Dividend
The impact of population structure on economic growth has been studied in recent decades using different methods to estimate the so-called demographic dividend. Besides, education has been pointed out as a key factor in economic growth. We propose a decomposition of the demographic dividend, into age and education effects. We illustrate the potentialities of the method, deriving an application to Mexico and Spain over the period 1970-2100. To tha…
Improving household-level nutrition-specific and nutrition-sensitive conditions key to reducing child undernutrition in India
Risk factors for chronic undernutrition among children in India
Individual and Ecological Variation in Child Undernutrition in India
Despite the substantial burden of child undernutrition in South Asia, little is known on the relative importance and contribution of individual and micro/macro environments in shaping variation in child undernutrition. Using measures of anthropometry, we decompose the variation in child undernutrition in India to the levels of child, communities and states, quantifying the extent to which variation at each of these levels can be explained by know…
The long-term mortality impact of combined job strain and family circumstances
Is low fertility really a problem? Population aging, dependency, and consumption
Longer lives and fertility far below the replacement level of 2.1 births per woman are leading to rapid population aging in many countries. Many observers are concerned that aging will adversely affect public finances and standards of living. Analysis of newly available National Transfer Accounts data for 40 countries shows that fertility well above replacement would typically be most beneficial for government budgets. However, fertility near rep…
