India's National Family Health Survey provides new information on maternal and child health and AIDS awareness

Teams surveyed a sample of 88,562 households, drawn from 99% of the population of India in 24 states plus the National Capital Territory of Delhi, between April 1992 and September 1993 to collect a basic set of information on all 500,492 household members, with more details on the 89,777 women in the households who had ever been married and were aged 13-49 years. This National Family Health Survey (NFHS) collected information from the women on a range of health topics including child immunization, women's knowledge of AIDS, services and facilities use during pregnancy and childbirth, infant feeding and treatment for diarrhea, and infant, child, and maternal mortality. Levels of infant and child mortality declined in India, but 8% of all children still die before their first birthday and 11% die before reaching age 5. As for maternal mortality, there are an estimated 420 maternal deaths per 100,000 live births annually. That rate implies that at least 100,000 Indian women die each year due to causes related to pregnancy and childbirth. Survey results indicate the need to strengthen vaccination programs and teach women about proper infant feeding practices. They also highlight the need to increase antenatal care and other medical services. In all of these areas, the NFHS results indicate wide variation among India's regions and states. Furthermore, a general lack of AIDS awareness suggests that the government's AIDS awareness campaign, relying primarily upon electronic media, has not yet reached the majority of India's population.     

The effect of female education on marital matches and child health in Bangladesh

This paper examines the effects of female education on marriage outcomes by exploiting the exogenous variation generated by the Female Secondary School Stipend Program in Bangladesh, which made secondary education free for rural girls. Our findings show that an additional year of female education leads to an increase in 0.72 years of husband’s education and that better educated women pair with spouses who have better occupations and are closer in age to their own, suggesting assortative mating. Those educated women appear to experience greater autonomy in making decisions on receiving their own health care and visiting their family. Furthermore, educated women have lower fertility and use more maternal health care, and their children have better health outcomes than those of less-educated women. Overall, our results suggest that the marriage market is one of the channels through which women’s education affects their life outcomes.     

Family size and maternal health: evidence from the One-Child policy in China

In this paper, we examine the impact of family size on maternal health outcomes by exploiting the tremendous change in family size under the One-Child policy in China. Using data from the China Health and Nutrition Survey 1993–2006, we find that mothers with fewer children have a higher calorie intake and a lower probability of being underweight and having low blood pressure; meanwhile, they have a higher probability of being overweight. This would occur if a smaller family size increases the food consumption of mothers, leading underweight women to attain a normal weight and normal weight women becoming overweight. Robust tests are performed to provide evidence on the hypothesis that the tradeoff between children’s quantity and mother’s “quality” is through a budget constraint mechanism, that is, having more children decreases the resource allocated to mothers and affects their health outcomes.     

The effect of child mortality experience on subsequent fertility: in Pakistan and Bangladesh

Summary This paper presents an empirical analysis of the effects, behavioural and biological, of child mortality experience on subsequent fertility in two South Asian Islamic nations. Data for the investigation came from retrospective pregnancy histories of 2,910 currently married women interviewed in the Pakistan National Impact Survey (1968-69) and from longitudinal vital registration data (1966-2070) of 5,236 women residing in a rural area of Bangladesh collected by the Cholera Research Laboratory. The aim of this study was to assess the importance of the child-replacement motivational response to child death experience after biological effects have been controlled adequately. A common approach employed previously has been to examine cumulative fertility according to child death experience. In Pakistan and Bangladesh, a consistently positive relationship was demonstrated between the number of children ever born and the number of child deaths. This method, however, did not exclude the inverse relationship, the influence of fertility on mortality, nor did it dissect out behavioural from biological effects. Utilizing a measure of subsequent fertility, live-birth-to-live-birth intervals, the study further illustrated another common pitfall. Since the risk of infant death, which leads to shorter birth intervals, is associated with the mother's reproductive history, women with child mortality experience are more likely to experience shorter intervals because of the biological effect of subsequent infant death. Behavioural influences may, therefore, be observed by considering only those birth intervals in which the first-born child survives to the end of the interval. With these limitations controlled, very few, if any, behavioural influences were noted in the Pakistan and Bangladesh data. Median birth intervals in Pakistan varied between 35-43 and 41-42 months, increasing with parity. Within each parity group, no consistent difference was observed between women with and without previous child loss. In Bangladesh, the median birth interval for all women with a surviving infant was 37-2 months. This was shortened to 24-31 months by an infant death. When intervals with infant deaths were excluded, little or no behavioural influence was detected among women of the same parity, but with varying levels of previous child loss. Even without behavioural effects, elimination of infant mortality in Bangladesh would reduce fertility by prolonging the average period of post-partum sterility. In the Bangladesh setting, however, the size of the effect was only about four per cent. This modest effect, more-over, was counterbalanced by an overall increase of net reproduction by seven per cent due to better survivorship of infants.     

Life expectancy and schooling: new insights from cross-country data

I argue that the relationship between life expectancy and schooling crucially depends on which measure of life expectancy one uses. In particular, I show that while the change in life expectancy at birth between 1960 and 1990 is positively correlated with percentage change in schooling, the change in life expectancy at age?5 is, at best, uncorrelated with percentage change in schooling. This evidence suggests that increasing life horizon beyond the early crucial childhood years for formal acquisition of human capital is not as quantitatively important as previously thought.     

Economic inequality and child stunting in Bangladesh and Kenya: an investigation of six hypotheses

Consistent with the increasing focus on issues of equity in developing countries, I extend the literature analyzing the relationship between economic inequality and individual health to the developing world. Using survey data from Bangladesh and Kenya with economic status measured by a wealth index and with three different geographic definitions of community, I analyze six competing hypotheses for how economic inequality may be related to stunting among children younger than 5 years old. I find little support for the predominant hypothesis that economic inequality as measured by a Gini index is an important predictor of individual health. Instead, I find that the difference between a household's wealth and the mean household wealth in the community is the measure of economic inequality that is most closely related to stunting in these countries. In particular, a 1 standard deviation increase in household wealth relative to the community mean is associated with a 30–32 percent decrease in the odds of stunting in Bangladesh and a 16–21 percent decrease in the odds of stunting in Kenya.     

Sibling rivalry and the gender gap: evidence from child health outcomes in Ghana

When capital and labor markets are imperfect, choice sets narrow, and parents must choose how to ration available funds and time between their children. One consequence is that children become rivals for household resources. In economies with pro-male bias, such rivalries can yield gains to having relatively more sisters than brothers. Using a rich household survey from Ghana, we find that on average if children had all sisters (and no brothers) they would do roughly 25-40% better on measured health indicators than if they had all brothers (and no sisters). The effects are as large as typical quantity-quality trade-offs, and they do not differ significantly by gender. Received: 22 May 1996 / Accepted: 13 July 1998     

Household structure and child nutrition: A reinterpretation of income and mother's education

Two frequently used predictors of child malnutrition are family income and mother's education. Despite their common sense rationale, they pose difficult and perhaps intractable problems of measurement and conceptualization. This paper proposes to substitute the concepts of family and maternal differentiation for these traditionally used indicators. Differentiation is defined as the capacity of the individual or group to process a diversity of information categories. Using data from a recent survey of households in Panama, indicators of this concept were constructed at the family and at the maternal levels using principal component analysis. These are shown to predict a range of indicators of childrens' nutritional status when appropriate control variables are included in the regression analysis. The same analysis was then repeated with income and mother's education replacing the differentiation measures. The results support our claim that the differentiation indicators are superior, and we argue that an even more important reason for using them is that they open the door to a long-term research program that is theoretically consistent and potentially cumulative.

Childbearing and Women's Survival: New Evidence from Rural Bangladesh

Effects of childbearing on women's mortality and the implications of family planning programs in reducing these effects are examined in a 20‐year prospective study of more than 2,000 women in Matlab, Bangladesh. Maternal mortality is defined as a death occurring in the six weeks after childbirth. But childbearing may affect women's survival beyond this brief period. Additional hypotheses considered relate to 1) cumulative exposure to childbearing, whether measured by parity or pace of childbearing, 2) age at first birth, and 3) effects beyond the reproductive ages. The results offer no support to cumulative exposure hypotheses, showing no link between parity or pace of childbearing and mortality risk. Instead, we identify an extended period of heightened mortality risk associated with each birth—the year of the birth and the two subsequent years. Family planning programs, by reducing the number of children and therefore a woman's exposure to extended maternal mortality risk, potentially increase survival. Research is needed to identify and address the specific causes of extended maternal mortality risk so that appropriate ameliorative programs may be developed.     

Using satellite remote sensing and household survey data to assess human health and nutrition response to environmental change

Climate change and degradation of ecosystem services functioning may threaten the ability of current agricultural systems to keep up with demand for adequate and inexpensive food and for clean water, waste disposal and other broader ecosystem services. Human health is likely to be affected by changes occurring across multiple geographic and time scales. Impacts range from increasing transmissibility and the range of vectorborne diseases, such as malaria and yellow fever, to undermining nutrition through deleterious impacts on food production and concomitant increases in food prices. This paper uses case studies to describe methods that make use of satellite remote sensing and Demographic and Health Survey data to better understand individual-level human health and nutrition outcomes. By bringing these diverse datasets together, the connection between environmental change and human health outcomes can be described through new research and analysis.     

Family planning and reproductive health: the link to environmental preservation

This paper seeks to refocus the attention of environmentalists on the importance of population trends to environmental sustainability and identifies prevention of unintended pregnancy as potential common ground for environmentalists and family planning advocates. The health and other welfare benefits of preventing unintended pregnancy are felt most keenly by individual women, men, and their families. At the same time, however, preventing unwanted pregnancies usually results in smaller family size, an important factor in slowing population growth and, as a result, a source of broader benefits—including environmental benefits—to society.     

Quantifying the costs of drought: new evidence from life satisfaction data

We estimate the cost of droughts by matching rainfall data with individual life satisfaction. Our context is Australia over the period 2001 to 2004, which included a particularly severe drought. Using fixed-effect models, we find that a drought in spring has a detrimental effect on life satisfaction equivalent to an annual reduction in income of A$18,000. This effect, however, is only found for individuals living in rural areas. Using our estimates, we calculate that the predicted doubling of the frequency of spring droughts will lead to the equivalent loss in life satisfaction of just over 1% of GDP annually.

Maternal and child health care: a key step for family planning

The Maternal-Child Health Division of the Qinghai Provincial Health Department, the United Nations Children's Fund, and the United Nations Fund for Population Activities are collaborating on a model maternal-child health care project set up in the province's pastoral area. The project encompasses perinatal services in Minhe and Huangyuan counties, development of maternal-child health services at the grassroots level in Hainan Prefecture, and educational classes on child care for national minorities. The population has doubled in this vast but sparsely populated part of China since the founding of the People's Republic, and this rapid population growth has had negative repercussions for animal husbandry. To address this problem, 26 maternal-child health centers have been established in provincial pastoral areas of Qinghai and there are 20 full-time workers. Modern midwifery services are available to 67% of the population; as a result, mortality has dropped to 50/1000.     

Women's lives and rapid fertility decline: Some lessons from Bangladesh and Egypt

The recent experiences of Bangladesh and Egypt show thatfertility can sustain impressive declines even when women's lives remain severely constrained.Since the late 1970s, rural and urban areas in both countries have experienced steadydeclines in fertility, with recent declines in rural Bangladesh similar to those in ruralEgypt, despite lower levels of development and higher rates of poverty. This paperprovides an in-depth exploration of the demographic transition in these two societies andaddresses three basic questions: (1) have measurable improvements in economic opportunities forwomen been a factor in the fertility decline?; (2) can preexisting differences in gender systemsexplain the more rapid fertility decline in Bangladesh, despite the more modest economicachievements?; (3) can the development strategies adopted by the governments ofBangladesh and Egypt, be seen as additional factors in explaining the similar rural fertilitydeclines despite dissimilar economic circumstances? The paper concludes that neither gender systemsnor changes in women's opportunities appear to have contributed to declining fertility.Indeed, low levels of women's autonomy have posed no barrier to fertility decline in eithercountry. However, there is a case to be made that Bangladesh's distinct approach to development,with considerable emphasis on reaching the rural poor and women and a strong reliance onnongovernmental institutions, may have played a part in accelerating the transition in thatenvironment and in helping women to become more immediate beneficiaries of that process.

     

Food Access and Shocks in Rural Households: Evidence from Bangladesh and Ethiopia

As remarked by Ravallion (J Dev Econ 99:201–209, 2012), the recent switch from arithmetic to geometric mean in the aggregation of the United Nations’ Human Development Index has caused a more severe inequality penalization of the index for less developed countries, with outlying consequences. We clarify and explain this fact and propose an aggregation function, the Trichotomy Mean, that depends on two parameters: one regulates the overall penalization of disequilibria (among or within dimensions) in analogy with Atkinson’s inequality aversion parameter for power means; the other modulates the Level Dependence of the Adjustment, a novel concept describing the behavior—decreasing, increasing, or constant—of penalization of given disequilibria for increasing index level. Unlike the geometric mean (which, incidentally, has decreasing LDA type), the TM remains valid for zero or negative—and does not distort for small positive—values of the input variables, thus permitting less restrictive raw-variable normalizations and to overcome the need for exogenous lower bounds. We compare the three versions of TM with the geometric mean in an empirical analysis on the HDI 2014 data. We finally illustrate the contributions of the TM to the development literature debate.
