Trends and Socioeconomic Gradients in Adult Mortality around the Developing World

We combine data from 84 Demographic and Health Surveys from 46 countries to analyze trends and socioeconomic differences in adult mortality, calculating mortality based on the sibling mortality reports collected from female respondents aged 15–49. The analysis yields four main findings. First, adult mortality is different from child mortality: while under‐5 mortality shows a definite improving trend over time, adult mortality does not, especially in sub‐Saharan Africa. The second main finding is the increase in adult mortality in sub‐Saharan African countries. The increase is dramatic among those most affected by the HIV/AIDS pandemic. Mortality rates in the highest HIV‐prevalence countries of southern Africa exceed those in countries that experienced episodes of armed conflict. Third, even in sub‐Saharan countries where HIV prevalence is not as high, mortality rates appear to be at best stagnating, and even increasing in several cases. Finally, the main dimension along which mortality appears to differ in the aggregate is by sex. Adult mortality rates in sub‐Saharan Africa have risen substantially higher for men than for women—especially so in the high HIV‐prevalence countries. On the whole, the data do not show large gaps by urban/rural residence or by school attainment.     

Continued Reductions in Mortality at Advanced Ages

Mortality data for 30 mostly developed countries available in the Kannisto–Thatcher Database on Old‐Age Mortality (KTDB) are drawn on to assess the pace of decline in death rates at ages 80 years and above. As of 2004 this database recorded 37 million persons at these ages, including 130,000 centenarians (more than double the number in 1990). For men, the probability of surviving from age 80 to age 90 has risen from 12 percent in 1950 to 26 percent in 2002; for women, the increase has been from 16 percent to 38 percent. In the lowest‐mortality country, Japan, life expectancy at age 80 in 2006 is estimated to be 6.5 years for men and 11.3 years for women. For selected countries, average annual percent declines in age‐specific death rates over the preceding ten years are calculated for single‐year age groups 80 to 99 and the years 1970 to 2004. The results are presented in Lexis maps showing the patterns of change in old‐age mortality by cohort and period, and separately for men and women. The trends are not favorable in all countries: for example, old‐age mortality in the United States has stagnated since 1980. But countries with exceptionally low mortality, like Japan and France, do not show a deceleration in death rate declines. It is argued that life expectancy at advanced ages may continue to increase at the same pace as in the past.     

Determinants of Infant Mortality in Older ASEAN Economies

Infant mortality in the Association of Southeast Asian Nations (ASEAN) has been declining, yet disparities remain between the nations. This paper therefore explores the determinants of infant mortality in the older ASEAN-4 economies, Malaysia, Thailand, Indonesia and the Philippines using an Autoregressive Distributed Lag (ARDL) Error Correction Model framework. The key findings of the study are: First, there is evidence of long-run relationships among infant mortality, education, female fertility, income and access to healthcare. Second, the determinants of infant mortality vary between countries. Female fertility emerged as the main determinant of infant mortality in Malaysia, while access to healthcare matter for infant mortality in Indonesia, and to a lesser extent for the Philippines. The income effect is significant for reducing infant mortality in Malaysia, while female education is important for Indonesia and Thailand. Third, the speed of adjustment of infant mortality rate is comparatively low in ASEAN-4.     

Determinants of Regional Variations in Infant Mortality in Rural India

An analytical framework is specified for understanding the determinants of infant mortality. It distinguishes between factors at three levels – village, household and individual – and arranges them in ascending order with respect to their proximity to infant mortality. Village and household-level factors are assumed to influence infant mortality indirectly by influencing at least one of the six individual-level factors. The present analysis of the data aggregated at the state level clearly demonstrates the importance of both medical and non-medical factors for explaining the observed regional differences in infant mortality in rural India. The percentage of births attended by trained medical personnel and poverty, are the two important determinants of regional variations in neo-natal mortality; and the village-level availability of medical facilities and the extent of triple vaccination are the two important determinants of post-neo-natal mortality. The influence of adult women's literacy on infant mortality is explained by better medical care at birth, and preventive and curative medical care during the post-neo-natal period. Medical factors have been shown to be slightly more important than non-medical factors. This suggests that it might be possible to reduce the high level of infant mortality currently prevalent in many states in India by simple preventive medical interventions.     

Child Mortality and Environment in Developing Countries

This paper studies child mortality and fertility in 61 developing countries including the Central Asian Republics (CARs). To control for simultaneity, an estimated value of fertility was used in the mortality equation and a final specification included only exogenous socio-economic, health and environmental variables. We confirm the importance of female literacy in explaining both fertility and mortality, and also find a measure of consumption for the poorest share of the population to be significant, while controlling for nutrition, health expenditure, and income distribution. Incidence of tuberculosis and female agricultural population proxy for environmental impacts, but in spite of these controls, approximately 41% additional mortality was estimated due to living in the CARs. The results fill gaps in the literature: we use a wider range of socio-economic and environmental health variables than previously in an encompassing analysis of mortality and fertility, and find evidence of excessive mortality in the CARs most likely linked to environmental degradation in the region.

United Nations/World Health Organization Meeting on Socio-Economic Determinants and Consequences of Mortality,Mexico City, 19-25 June 1979

The objectives of the United Nations/World Health Organization (WHO) Meeting on Socioeconomic Determinants and Consequences of Mortality, held in Mexico City in June 1979, were the following: to review the knowledge of differential mortality and to identify gaps in the understanding of its socioeconomic determinants and consequences; to discuss the methodological and technical problems associated with data collection and analysis; to consider the policy implications of the findings presented and to promote studies on the implications of socioeconomic differentials in mortality on social policy and international development strategies; to formulate recommendations and guidelines for the utilization of the 1980 round of population censuses for in-depth studies of mortality differentials; and to stimulate national and international research on differential mortality. Participants discussed the state of knowledge of socioeconomic differentials and determinants of mortality and described the socioeconomic measures available, the methods of data collection and analysis used, and the findings themselves. A number of characteristics had been employed in the study of differential mortality, and these could be grouped under the following headings: occupation; education; housing; income, wealth; family size; and place of residence. The techniques or methods used to analyze mortality were direct and indirect methods, and these are examined. Inequalities in mortality were found to be closely associated with inequalities in social and economic conditions. Any effort to reduce or remove those inequalities would have to be based on a clear understanding of their causes and interrelationships in order to succeed. Participants indicated a desire to see a resurgence of mortality research, and some research suggestions are outlined.     

Death Clustering,Mothers' Education and the Determinants of Child Mortality in Rural Punjab,India

In this paper the behavioural factors which make for continuing high levels of child mortality in rural Punjab, despite favourable conditions in terms of nutrition, income, women's literacy and health care facilities are examined. A major factor is that inadequate attention has been paid to improved health care practices within the home. Women's autonomy, social class, and mothers' education significantly influence child survival. One of the pathways by which mothers' education affects child survival is through improved child care. In this society, a woman's autonomy is lowest during that part of her life-cycle which also contains her peak childbearing years: this perverse overlap raises child mortality. The risk of dying is distributed very unevenly amongst children, as the majority of child deaths are clustered amongst a small proportion of the families. The death-clustering variable remained significant even after several possible biological and socio-economic reasons for clustering had been controlled. It is argued that this clustering of deaths is partly due to the poor basic abilities of some mothers and other carers.     

Demographic Determinants of Infant and Early Child Mortality: A Comparative Analysis

In this paper we examine the relative importance of a number of demographic determinants of infant and early child mortality using information from 39 World Fertility Survey countries. We include sex of the child, age of the mother at the time of the birth, birth order, mother's educational level and a number of indicators of spacing of adjacent births among the correlates of chances of survival for children below the age of five years. Mortality of firstborn children and of those born to teenage mothers is shown to be higher than average; that of later children and those of older mothers was not much higher than average, once other factors are controlled. Effects of poor birth-spacing persist even after other factors have been controlled, and are similar where a sib was born during the two years preceding the birth of the child, regardless of the survival status of that sib; however, mortality was higher when that sib had died, due to increased familial risks of mortality. Rapid subsequent births also raise mortality for their earlier sibs. The findings are generally remarkably consistent in a wide range of countries and associated mortality conditions, although attention is drawn to a few interesting geographically clustered exceptions which deserve further investigation. The study leaves little room for doubt that poor child-spacing is clearly linked to decreased survival chances.     

Macro-Structural Determinants of Political Freedom in Developing Countries: A Cross-National Analysis

This study attempts to evaluate the impacts of macro-structural factors on political freedom in developing countries (DCs). Political freedom is conceptualized as civil liberty and political rights the general population of a society can enjoy in influencing public policy. The Freedom House indexes are used as measures of freedom. In explaining the individual countries’ differences in political freedom, this study considers the following factors: regime types, level of development, social structure, fractionalization, the state and military influence and external economic dependence. Empirical modeling of 118 DCs with regression techniques and ordered logit methods demonstrates that besides the regime effects, economic development generates favorable influence, while a large poor population and military spending produce negative impact on freedom. In the concluding section, we discuss the theoretical implications in comparative perspective.     

Gender and Aging in the Developing World: Where Are the Men?

In recent years, both population aging and gender issues have gained prominence in international forums concerned with population. It is frequently asserted or implied that older women are universally more vulnerable to social, economic, and health disadvantages than older men. The most significant manifestation of this exclusive concern with women when considering gender and aging is the Plan of Action adopted by the Second World Assembly on Aging in 2002. The assumed relative disadvantage of elderly women is commonly attributed to gender differences in earlier life experiences. But are older women truly disadvantaged globally with respect to all or most essential aspects of well‐being? The authors provide empirical evidence that clearly shows that older women are not invariably disadvantaged vis‐à‐vis men. In particular, they call into question the wisdom and equity of a virtually exclusive emphasis on the needs of women when incorporating gender concerns into policies and programs related to aging. A more balanced perspective that recognizes gender as a potential, but not necessarily central, marker of vulnerability for various aspects of well‐being in specific settings and times, and that allows for male as well as female disadvantage, would serve the current and future elderly generations far better.     

Determinants of Mortality at Older Ages: The Role of Biological Markers of Chronic Disease

Researchers have had a longstanding interest in understanding the determinants of mortality. This article examines the impact of a broad array of biological markers, together with self‐reports of physical and mental health status, on the probability of dying for older adults. The estimates are derived from logistic regression models based on data from a national survey in Taiwan. The analysis confirms previous studies demonstrating the effects of clinical measures related to metabolic syndrome on mortality and identifies detrimental effects of neuroendocrine and immune‐system markers. The results reveal that biomarkers provide independent explanatory power in the presence of self‐reported health measures. The associations between biomarkers and mortality found here provide new avenues for projecting future mortality and elucidating differences in longevity across populations.     

Household and Context Determinants of Child Labor in 221 Districts of 18 Developing Countries

We develop a new theoretical framework that explains the engagement in child labor of children in developing countries. This framework distinguishes three levels (household, district and nation) and three groups of explanatory variables: Resources, Structure and Culture. Each of the three groups refers to another strand of the literature; economics, sociology and anthropology. The framework is tested by applying multilevel analysis on data for 239,120 children living in 221 districts of 18 developing countries. This approach allows us to simultaneously investigate effects of household and context factors. At the household level, we find that resources and structural characteristics influence child labor, whereas cultural characteristics have no effect. With regard to context factors, we find that children work more in rural areas, especially if there are more unskilled manual jobs, and in more traditional urban areas. In more developed regions, girls tend to work significantly less.     

Determinants of mortality transition in developing countries before and after the Second World War: Some evidence from Cuba

Few studies provide an insight into what factors contributed to declines in the mortality rates of developing countries before the Second World War. In this paper, statistics on causes of death from Cuba, particularly Havana, are used to investigate what may have been some of the principal determinants of mortality decline in the developing world before the arrival of modern drugs and insecticides. Trends in cause-specific mortality are examined in the light of Cuba's social, economic, medical and public health history. The Cuban experience strongly suggests that in this country public health and sanitary reforms and nutritional improvements were largely responsible for initial declines in mortality throughout the first half of the twentieth century. One important finding is that the impact of these reforms and improved nutrition was greatly influenced by prevailing economic conditions. Periods of economic prosperity facilitated declines in mortality; but in times of adversity, the reverse occurred. It appears that during prosperous periods the maintenance and expansion of public health and sanitary facilities were made possible by increased public and private revenues, and that individuals had access to a more abundant diet. The severe economic crisis of the Great Depression had the opposite effect. With the appearance of sulphonamides in the late 1930s, antibiotics, and residual insecticides and other specific measures at the end of the Second World War, the relevance of economic conditions as a determinant of mortality decline diminished. Although this analysis points to the aforementioned trends, the Cuban experience also suggests that other factors enter into the process of declining mortality and that this phenomenon can only be explained as the result of the complex interplay of many forces.

Multinational Corporations,Democracy and Child Mortality: A Quantitative,Cross-National Analysis of Developing Countries

This study presents quantitative, sociological models designed to account for cross-national variation in child mortality. We consider variables linked to five different theoretical perspectives that include the economic modernization, social modernization, political modernization, ecological-evolutionary, and dependency perspectives. The study is based on a cross-lagged effects regression analysis of a sample of 59 developing countries. Our preliminary analysis based on additive models replicates prior studies to the extent that we find that indicators linked to economic and social modernization have beneficial effects on child mortality. We also find support for hypotheses derived from the dependency perspective suggesting that multinational corporate penetration fosters higher levels of child mortality. Subsequent analysis incorporating interaction effects suggest that the level of political democracy conditions the effects of dependency relationships based upon multinational corporations. Transnational economic linkages associated with multinational corporations adversely affect child mortality more strongly at lower levels of democracy than at higher levels of democracy–that is intranational, political factors interact with the international, economic forces to affect child mortality. We conclude with some brief policy recommendations and suggestions for the direction of future research.     

Mortality of the chronically impaired

An analysis of the effects of diabetes and generalized atherosclerosis on death due to ischemic heart disease or stroke was conducted using multiple cause mortality statistics. Specifically, all U.S. deaths in 1969 were classified into two groups on the basis of whether diabetes or generalized atherosclerosis was mentioned anywhere on the death certificate. Then race and sex specific analyses were made of ischemic heart disease deaths (or alternately of stroke deaths) using modified life table techniques for each group (one with the specified chronic disease and one without). Comparisons were made of mortality due to the acute circulatory events (ischemic heart disease or stroke) in the two groups to determine the implications of the chronic disease for the progression of the circulatory disease events. It was found, according to expectations, that diabetes and generalized atherosclerosis play very different roles in deaths due to stroke and ischemic heart disease.

Nondrinker Mortality Risk in the United States

The literature has shown that people who do not drink alcohol are at greater risk for death than light to moderate drinkers, yet the reasons for this remain largely unexplained. We examine whether variation in people’s reasons for nondrinking explains the increased mortality. Our data come from the 1988–2006 National Health Interview Survey Linked Mortality File (N = 41,076 individuals age 21 and above, of whom 10,421 died over the follow-up period). The results indicate that nondrinkers include several different groups that have unique mortality risks. Among abstainers and light drinkers the risk of mortality is the same as light drinkers for a subgroup who report that they do not drink because of their family upbringing, and moral/religious reasons. In contrast, the risk of mortality is higher than light drinkers for former drinkers who cite health problems or who report problematic drinking behaviors. Our findings address a notable gap in the literature and may inform social policies to reduce or prevent alcohol abuse, increase health, and lengthen life.
