Factors associated with trends in infant and child mortality in developing countries during the 1990s.

The 1990s have seen a remarkable decrease in mortality among infants and children in most developing countries. In some countries, particularly in sub-Saharan Africa, these declines in mortality among children have slowed and are now increasing again. Internationally comparable data derived from survey programmes, such as the Demographic and Health Survey (DHS) programme, are available both to document the changes that have occurred in mortality and to provide insight into some of the factors that may explain these trends in mortality. The factors found in repeated DHS programmes that explain these trends fall into five categories: fertility behaviour; nutritional status, breastfeeding, and infant feeding; the use of health services by mothers and for children; environmental health conditions; and socioeconomic status. Both simple analyses and multivariate analyses of changes in these factors between surveys indicate that all factors affected the mortality trends. However, to explain trends in mortality, the variables themselves had to have changed over time. During the 1990s fertility behaviour, breastfeeding, and infant feeding have changed less than other factors and so would seem to have played a smaller role in mortality trends. This study confirms that trends in mortality during the 1990s were related to more than just a handful of variables. It would, therefore, be a mistake to concentrate policy actions on one or a few of these while forsaking others. Countries with the largest decreases in mortality have had substantial improvements in most of the factors that might be used to explain these changes. In some countries mortality has risen. In part these increases can be explained by the factors included in this study, such as deterioration in seeking medical care for children with fever. Other factors that were not measured, such as the increasing resistance of malaria to drug treatment and the increased prevalence of parental HIV/AIDS, may be contributing to the increase noted.

[Data on birthweight in developing countries: are surveys useful?].

The main source of data on birth weight in developing countries is statistics from health facilities, although most developing countries do not produce annual estimates of the incidence of low birth weight from these data. Such estimates would be subject to selection bias as the data are usually limited to babies born within health facilities, and therefore are representative of a subgroup that is markedly different from the overall population of neonates. Since 1990 the Demographic and Health Surveys programme has included questions on recalled birth weight and relative size at birth in 15 national surveys. In this article, we show that these cross-sectional surveys can provide a useful data source for making national estimates of mean birth weight and the incidence of low birth weight. The extent of misclassification of birth weight is, however, too large to use the data on relative size as birth as an indicator of low birth weight at the individual level.

Contraceptive use during lactational amenorrhea.

OBJECTIVE: The study uses data from nationally representative sample surveys in developing countries to estimate the overlap between lactational amenorrhea and contraceptive use during the first 6 months postpartum. METHOD: Secondary analyses of survey data were used to tabulate the proportion of the population in lactational amenorrhea among contraceptive users for all women, for postpartum women and for the country as a whole. RESULTS: Among postpartum women, the proportion in lactational amenorrhea was particularly high in Africa and the Near East and lower in Latin America and the Caribbean where breast-feeding practices have declined. The median duration of use for oral contraceptives is also presented as an aid to interpreting the significance of the findings. CONCLUSIONS: The significance of the findings is considered in the context of planning reproductive health services in the postpartum period. Decisions about timing of contraceptive use for postpartum women, while arrived at on an individual basis, also result from program strategies that focus counseling immediately postpartum or at a later interval, such as when menses resume. On a national level the impact of postpartum contraception policies on use of commodities may be substantial.

The use of breast milk substitutes in developing countries: the impact of women's employment.

OBJECTIVES: This study quantified the influence of employment, specifically a mother's employment away from her infant, on the use of breast milk substitutes in developing countries. METHODS: Data from the Demographic and Health Surveys were used to calculate the population attributable risk percentage for use of breast milk substitutes among women employed away from their babies in 15 countries for which suitable data were available. RESULTS: The estimated proportion of breast milk substitute use attributable to employment away from the baby ranged from 0.74% to 20.9% in the various countries. CONCLUSIONS: Employment is not the main determinant of breast milk substitute use. Efforts to improve breast-feeding can be safely targeted at the majority of women who are not employed away from their babies while nevertheless giving appropriate attention to the minority of new mothers who are employed away from their babies.

Data on birth weight in developing countries: can surveys help?

Accuracy and completeness of mothers' recall of diarrhoea occurrence in pre-school children in demographic and health surveys.

In the context of the Demographic and Health Surveys program (DHS), data were collected on diarrhoeal diseases in childhood and related treatment patterns. In this paper we assess the accuracy and completeness of mothers' recall of diarrhoea in 19 national DHS surveys and discuss the implications for health interview surveys in developing countries. It is concluded that there is under-reporting of diarrhoea if the recall period is longer than 2-3 days, whereas there may be over-reporting of very recent or current diarrhoea in most DHS surveys. Reporting errors appear to vary considerably between countries, which affects the comparability of survey results. A second and related issue, that is addressed in this paper, is the reporting of treatment practices by duration of diarrhoeal episode. There were no major differences in reported treatment patterns between children with diarrhoea that terminated in the last two weeks and children with current diarrhoea of at least two days' duration. The implications of the findings for retrospective surveys on childhood morbidity and treatment patterns are discussed.

Bottle use for infant feeding in developing countries: data from the demographic and health surveys. Has the bottle battle been lost?

This paper uses data from 22 national surveys in developing countries to estimate the use of bottles for feeding of infants under 6 months of age. These data were collected in the context of the Demographic and Health Surveys programme (DHS) between 1986 and 1989. Bottle use appears to be very common in most countries. Only six of the 22 countries had levels of bottle use of less than 20 per cent, and all these countries are in sub-Saharan Africa. The policy implications are discussed briefly.

Comparison of microcomputer programs for making population projections: an update.

"There are many programs for making population projections now available for use with microcomputers. This article reviews six of approximately 15 microcomputer population projection programs. Each program is compared to a standard set of criteria relating to such items as hardware and software requirements, input data requirements and specification of assumptions, methodology and documentation, and summary output indicators. Numerical results from projections of six test data sets reflecting different assumptions about mortality, fertility, and migration are compared. Qualitative comments are included for describing special features and for making an overall assessment of each program." (SUMMARY IN FRE)
