Two determinants of fertility decline: a test of competing models.

This paper compares alternative models for the process by which education and infant mortality changes may combine to reduce fertility. A linear, interactive model appears most suitable. Substantively, it indicates that those countries with a combination of low infant mortality rates and high educational enrollments experience synergistically large declines in fertility. Patterns of contraceptive use are also consistent with this model.

Infant mortality in Bangladesh: a review of recent evidence.

Estimates of child mortality are mainly based on reports by mothers on the survival status of their children. Infant mortality estimates from such data do not seem to have declined in recent years. The Bangladesh Bureau of Statistics sample registration infant mortality estimates appear to be suspiciously low.

Malaria chemoprophylaxis, birth weight and child survival.

Study of the effects of malaria chemoprophylaxis given during pregnancy on birthweight and investigation of the influence of birthweight on child survival suggest that, in a rural area of The Gambia, chemoprophylaxis given during pregnancy might reduce infant mortality by about one-fifth in the children of primigravidae but by less than 5% in the children of multigravidae. In malaria endemic areas, primigravidae should be protected against malaria not only for their own sake but also for that of their infants.

Estimating infant mortality rates prospectively in Honduras.

In order to determine the validity of infant mortality estimates based on retrospective reporting, the Honduran Ministry of Health carried out a follow-up survey of women interviewed in a 1987 national survey. Women were interviewed approximately 14 months after the baseline survey and were asked about the outcomes of their pregnancies and the survival status of their young children. The overall infant mortality rate calculated from the follow-up survey was lower than that obtained from the baseline survey, due to the particularly low rate among the group of women who were pregnant at the time of the baseline survey. Possible explanations for this low rate are discussed.

Primary medical care in Seychelles.

This paper describes some of the current health problems faced by a tropical country whose standard of living and lifestyle is approaching that of many countries in Western Europe. Long-term health problems such as cardiovascular diseases and diabetes have become at least as important as infectious diseases. A change in approach to a more proactive style of primary care is needed to allow the contribution of community doctors to be effective. The system of primary care in the Republic of Seychelles is based on the UK model of general practice where recent improvements in education and organization are raising standards. How some of these improvements might be transferred elsewhere is discussed.

Infant mortality and crisis in Mexico.

Data derived from the Encuesta Nacional de Fecundidad y Salud (ENFES) confirm that overall levels of infant mortality in Mexico have been steadily declining. However, a more specific analysis furnishes evidence that this decline has occurred at varying rates within different social groups, reflecting an increase in social inequalities. The analytical strategy used in this article leads to three basic conclusions: (1) the impact of the economic crisis on infant mortality is reflected not in a reversal of the declining trend but an increase in social inequalities; (2) certain variables universally accepted as determinants of infant mortality, such as mother's education, seem nonsignificant for some social sectors; and (3) certain biodemographic characteristics assumed to have a uniform mortality-related behavior vary among sectors, suggesting that even these constants are determined by social factors.

Expanded programme on immunization (EPI). Safety of high titre measles vaccines.

Unexpected results suggesting decreased survival when compared with standard titre vaccine administered at 9 months of age have been found in some field studies evaluating the performance of high titre measles vaccine. Analytical difficulties have arisen because the studies were not specifically designed to measure survival. Nonetheless, careful analysis of the results from all of the high titre vaccine trials showed decreased survival of high titre vaccine recipients, in areas with high background mortality rates, compared with recipients of standard measles vaccines at 9 months. No systematic biases could be found in the studies to explain these differences. Statistical analysis of these data suggested that the findings were unlikely to be attributable to chance alone. The panel recommended that high titre measles vaccine derived from the original Edmonston measles vaccine isolate should no longer be recommended for use in immunization programmes. Further post-licensure field studies of new measles vaccines should take into account the results of these studies. Additional detailed epidemiological studies in populations that have received high titre vaccines and their controls were encouraged.

Reduction in total under-five mortality in western Nepal through community-based antimicrobial treatment of pneumonia.

Pneumonia is a leading cause of death among children world wide but those at highest risk in developing countries have limited access to clinical services; effective and low-cost alternatives are a global public health priority. We have done a controlled intervention trial among 13,404 children under five in Jumla, Nepal, which relied exclusively on indigenous community health workers to detect and treat pneumonia according to the World Health Organisation decision strategy, with a five-day home-treatment course of oral co-trimoxazole. No other health services were provided, and referral of children to hospital was not practicable. During the three-year study, 2101 deaths were recorded. The programme led to a 28% reduction in the risk of death from all causes by the third year of services (relative risk 0.72, 95% confidence interval 0.63-0.82), with a significant trend (p less than 0.02) of lower mortality with greater duration of the programme. The greatest benefit was among infants. In addition to reduction in deaths due to pneumonia, there was a significant reduction in deaths due to diarrhoea and measles, indicating that reduction in pneumonia morbidity had considerable carry-over effect. Our findings show that indigenous community workers can effectively detect and treat pneumonia, and reduce overall child mortality, even without other primary care activities.

The effect of insecticide-treated bed nets on mortality of Gambian children.

Insecticide treatment of bed nets ("mosquito nets") may be a cheap and acceptable method of reducing the morbidity and mortality caused by malaria. In a rural area of The Gambia, bed nets in villages participating in a primary health-care (PHC) scheme were treated with permethrin at the beginning of the malaria transmission season. Additionally, children aged 6 months to 5 years were randomised to receive weekly either chemoprophylaxis with maloprim or a placebo throughout the malaria transmission season. We measured mortality in children in PHC villages before and after the interventions described, and compared this with mortality in villages where no interventions occurred (non-PHC villages). About 92% of children in PHC villages slept under insecticide-treated bed nets. In the year before intervention, mortality in children aged 1-4 years was lower in non-PHC villages. After intervention, the overall mortality and mortality attributable to malaria of children aged 1-4 in the intervention villages was 37% and 30%, respectively, of that in the non-PHC villages. Among children who slept under treated nets, we found no evidence of an additional benefit of chemoprophylaxis in preventing deaths. Insecticide-treated bed nets are simple to introduce and can reduce mortality from malaria.

Seasonality of disease in Kuwait.

To compare the seasonal variation in total mortality and deaths from cardiovascular, respiratory, and malignant disease, data were collected from North-East Scotland (Grampian region) and Kuwait. Seasonal differences were similar, in both timing and degree, for total mortality and deaths from circulatory disease, but were greater in Kuwait for respiratory disease. Peak mortality was during winter in both areas: in Grampian, when the climate is most uncomfortable, and in Kuwait, when the climate is at its most comfortable. Socioeconomic changes in Kuwait have been accompanied by a rapid fall in the degree of seasonality (deseasonality) for both total and infant mortality. These findings suggest that mortality peaks in winter, not because of a seasonally low temperature, but because of a seasonal fall in mean temperature irrespective of the annual mean temperature.

Sexual contact patterns between men and women and the spread of HIV-1 in urban centres in Africa.

A simple model of the transmission of HIV-1 by heterosexual contact and from mother to unborn infant is developed to assess the influence of patterns of mixing between low and high sexual activity classes of the two sexes on the pattern of spread of the virus and the demographic impact of AIDS. Numerical studies of model behaviour are based, where possible, on parameter estimates derived from epidemiological studies of HIV-1 spread in Africa. Analyses reveal that the assumed pattern of mixing, ranging from assortative (like with like) through random (proportional) to disassortative (like with unlike), has a very major impact on the predicted spread of the virus and the concomitant demographic impact of AIDS. Patterns of strong assortative mixing are predicted to generate the least spread and demographic impact, by comparison with proportional or disassortative mixing. Analyses also reveal that the rules governing behaviour changes, once AIDS-induced mortality changes the structure of the population (i.e. the numbers in the low and high sexual activity classes of the two sexes), have a very significant influence on the course of the epidemic. Where possible, predicted patterns are compared with observed trends in Africa.

Childhood mortality after a high dose of vitamin A in a high risk population.

OBJECTIVES: To determine whether a single high dose of vitamin A given to all children in communities with high mortality and malnutrition could affect mortality and to assess whether periodic community wide supplementation could be readily incorporated into an ongoing primary health programme. DESIGN: Opportunistic controlled trial. SETTING: Jumla district, Nepal. SUBJECTS: All children aged under 5 years; 3786 in eight subdistricts given single dose of vitamin A and 3411 in remaining eight subdistricts given no supplementation. MAIN OUTCOME MEASURES: Mortality and cause of death in the five months after supplementation. RESULTS: Risk of death for children aged 1-59 months in supplemented communities was 26% lower (relative risk 0.74, 95% confidence interval 0.55 to 0.99) than in unsupplemented communities. The reduction in mortality was greatest among children aged 6-11 months: death rate (deaths/1000 child years at risk) was 133.8 in supplemented children and 260.8 in unsupplemented children (relative risk 0.51, 0.30 to 0.89). The death rate from diarrhoea was also reduced (63.5 supplemented v 97.5 unsupplemented; relative risk 0.65, 0.44 to 0.95). The extra cost per death averted was about $11. CONCLUSION: The results support a role for Vitamin A in increasing child survival. The supplementation programme was readily integrated with the ongoing community health programme at little extra cost.

Mortality trend in a rapidly developing economy in Taiwan. Part II: Life expectancy and "potential years of life lost".

Taiwan has made remarkable economic progress in the last 30 years. The life expectancy of its population improved steadily during this period. A male child born in 1983 could look forward to 70.4 years of life and a female child to 75.3 years, gains of 17.5 years and 19.0 years, respectively, since 1950. The potential gains in life expectancy of the Taiwan population are also examined if the five leading causes of death are reduced or eliminated. In addition, this paper discusses the concept of potential productive years of life lost (PYLL), examines the leading causes of premature death and shows how this measure can be used to target prevention programs and health care planning.

Standardized mortality ratios for Israel, 1983-86.

Standardized mortality ratios (SMRs), standardized by age, sex, continent of birth, and religion are presented by cause and region for the period 1983-86. Regional SMRs ranged from 90.6 in Jerusalem to 107.6 in Ramla. These differences may be due to direct and indirect occupational, environmental and socioeconomic effects as well as to possible health service differences. SMRs can be used to indicate regions where further in-depth epidemiological investigations are called for in order to ascertain the reasons for elevated disease specific SMRs. In addition, SMRs could be used as a global measure of all effects in order to adjust any regional budgetary allocation formula, based on capitation.
