Levels and risk factors for perinatal mortality in Ahmedabad, India.

To estimate levels and determinants of perinatal mortality, we conducted a hospital-based surveillance and case-control study, linked with a population survey, in Ahmedabad, India. The perinatal mortality rate was 79.0 per 1000, and was highest for preterm low-birth-weight babies. The case-control study of 451 stillbirths, 160 early neonatal deaths and 1465 controls showed that poor maternal nutritional status, absence of antenatal care, and complications during labour were independently associated with substantially increased risks of perinatal death. Multivariate analyses indicate that socioeconomic factors largely operate through these proximate factors and do not have an independent effect. Estimates of attributable risk derived from the prevalence of exposures in the population survey suggest that improvements in maternal nutrition and antenatal and intrapartum care could result in marked reductions of perinatal mortality.

[Abortion as a cause of maternal mortality].

It has been shown that 65.8% of 343 women died in the second trimester and 69.6% after an illegal abortion. Sepsis and peritonitis were the main causes in the general population (73.9%) and in women who died from illegal abortions (88.6%). Defects in medical care were found.

[Fertility and health in Mexico].

Fertility, health, and family planning are not independent factors, but rather involve a series of biological and social mechanisms in close interaction with one another. The impact that a high fertility rate has on health is reflected mainly in a rise in the rates of maternal and child mortality. Similarly, fertility has a greater negative effect upon the health of groups characterized by high reproductive risk, high parity, short intergenesic intervals, and unwanted pregnancies. On the other hand, family planning -and specifically the use of contraceptive methods-helps to achieve a lowering of the fertility rate and also has a positive effect on maternal-child health. This situation can be observed in the case of Mexico, where fertility rates and tendencies, as well as maternal and child mortality, have been reduced during the past decade.

The Lao People's Democratic Republic: maternal mortality and female mortality: determining causes of deaths.

A sample of 380 female deaths in the age group 15-49 years from 16 provinces of the Lao People's Democratic Republic were analyzed to determine the most likely cause of death. 127 deaths were classified as maternal, 28% occurred during pregnancy and the remaining 72% within six weeks of the termination of pregnancy. Almost three quarters of all maternal deaths were directly related to obstetrical complications during pregnancy or childbirth. Many of these deaths could probably have been avoided, if appropriate obstetric care had been available. The level of attention to problems related to maternity and childbirth needs to be raised at all responsible levels of the health service system. This must start at the health facility where attending nurses and midwives should be oriented towards pregnancy-related problems and early detection of high-risk women, with appropriate supervisory support. District and national administrations should also focus more on maternity services within their Primary Health Care programme.

Maternal marital status as a risk factor for infant mortality.

The increased risk of infant mortality associated with single motherhood is neither consistent among social and demographic subgroups nor inevitable, according to data from national linked birth and infant death files for 1983-1985. Maternal age is the only variable found to have a significant interaction with marital status among black mothers, and the risk associated with unmarried status increases with age. Among white mothers, age, educational level and receipt of prenatal care all show significant interactions with marital status; the increased risks of infant mortality attributed to unmarried motherhood are concentrated among subgroups usually thought to be at lower risk. For example, the risks of infant mortality among unmarried white women relative to married white women are highest among 25-29-year-olds. However, being unmarried did not affect the risk of infant mortality among babies born to college-educated white women.

The effects of breast-feeding and the pace of childbearing on early childhood mortality in Mexico.

Using data from Mexico's Demographic and Health Survey, the authors examine the effects of breast-feeding and the pace of childbearing on early childhood mortality in a sample of 2,665 children born between 1982 and 1986. From a family planning perspective, they seek to assess the impact that changes in childbearing patterns and associated changes in breast-feeding patterns may have on infant and childhood mortality. This is done by integrating breast-feeding models with variables influencing the pace of childbearing. The analysis indicates that the effects of breast-feeding on infant mortality were strong, consistently negative, and statistically significant until at least the sixth month of life, after which they were considerably diluted. Among the other variables analyzed, the effects of a following conception on mortality were found to be very strong among infants 3-5 months old; and maternal age at delivery appeared to have some importance among infants 1-2 months old and among children in the second year of life. To examine likely interactions between family planning, breast-feeding, and mortality, an integrated model was applied that simultaneously considered these and a range of other variables. The results suggest that the effects of improved birth spacing and maternal age at delivery associated with family planning are powerful enough to cause 20-40% reductions in infant mortality. However, the effects of reduced breast-feeding associated with family planning are great enough to offset more than 60% of these benefits. Limitations of the model make it necessary to emphasize that all of these conclusions need to be accepted with caution.

Aspects of neonatal death in St Kilda, 1830-1930.

Neonatal death (mainly due to tetanus) was common in St Kilda until 1891. Two aspects of this phenomenon are studied; factors which predicted death, and the impact of neonatal death on family building. Maternal age appeared to be a predictive factor for death of the first child, but only in children of high birth order were other factors, particularly the number of previous neonatal deaths, important. The first birth interval appeared to be determined mainly by the date of the first birth, independent of neonatal mortality levels. For later intervals, the neonatal death of the previous child appeared to be the main determining factor.

Estimating child mortality in Zimbabwe: results of a pilot study using the preceding births technique.

Using the preceding birth technique, 2,229 mothers were interviewed at four antenatal centres (two of which were urban) over a three month period during a pilot study in Zimbabwe. Results of the study showed that there was a small difference between the under two and under five mortality. The smaller than expected difference could have been due to some degree of urbanisation being experienced at two of the centres, and to a systematic selection bias of the method. Other findings of the study showed that younger mothers (under 20 years of age) and older mothers (over 40 years) experienced higher proportions of mortality, than mothers in the age group between. The higher proportion of male mortality compared to that for females reflected the expected trend, but the size of the difference was somewhat surprising, and could have been due to recall bias. The mean birth interval was 36 months, rather than the expected 30 months, and analysis of mortality in relation to birth interval and maternal age showed that a birth interval of less than 18 months was associated with higher child mortality, significantly so with the second last child, independent of mother's age. Longer birth intervals (more than three years) among older mothers were associated with higher changes of child survival. It is concluded that the Brass-Macrae method is a useful technique to analyse levels and trends of child mortality.

The Butajira project in Ethiopia: a nested case-referent study of under-five mortality and its public health determinants.

During one year of follow-up, 306 deaths of children under the age of 5 years were included in a concurrent case-referent study that was based on a population estimated at 28,780 in 1987. A total of 612 live referents, matched for age, sex and study area, were also selected from the study population through density sampling. Data were collected by lay reporters by verbal autopsy. For the study period the estimated cumulative under-five mortality rate was 293 and the infant (0-11 months old) mortality rate was 136 per 1000. Major probable causes of death were diarrhoeal disease or acute respiratory infections (ARI). The relative importance of parental and environmental characteristics was assessed using conditional multiple logistic regression analysis. Under-five mortality was associated with paternal illiteracy, maternal ethnicity, and not being in the committee of people's organizations. Parental factors affected the infants relatively more than they did the children, especially with regard to ARI mortality. This was also noted with "absence of window", a proxy measure for evaluating the type of housing. In terms of etiological fractions a greater number of under-five deaths could be ascribed to parental than environmental conditions, with relatively more infants being affected than children.

Factors influencing infant mortality in Vietnam.

Selected determinants of overall infant mortality in Vietnam were examined using data from the 1988 Vietnam Demographic and Health Survey, and factors underlying neonatal and post-neonatal mortality were also compared. Effects of community development characteristics, including health care, were studied by logistic regression analysis in a subsample of rural children from the 1990 Vietnam Accessibility of Contraceptives Survey. Infant neonatal and post-neonatal mortality rates showed comparable distributions by birth order, maternal age, pregnancy intervals, mother's education and urban-rural residence. Rates were highest among first order births, births after an interval of less than 12 months, births to illiterate mothers and to those aged under 21 or over 35 years of age. Logistic regression analysis showed that the most significant predictor of infant mortality was residence in a province where overall infant mortality was over 40 per 1000 live births. In the rural subsample, availability of public transport was the most persistent community development predictor of infant mortality. Reasons for the low infant mortality rates in Vietnam compared to countries with similar levels of economic development are discussed.

Perinatal mortality in rural Malawi.

Reported are the results of a study to assess the prevalence and risk factors for perinatal death among pregnant women in Malawi over the period 1987-90. There were 264 perinatal deaths among the 3866 women with singleton pregnancies (perinatal mortality rate, 68.3 per 1000 births). Among the risk factors for perinatal mortality were the following: reactive syphilis serology, nulliparity, a late fetal or neonatal death in the most recent previous birth, maternal height < 150 cm, home delivery, and low socioeconomic status. Although unexplained perinatal deaths will continue to occur, perinatal mortality can be reduced if its causes and risk factors in a community are given priority in antenatal and intrapartum care programmes. The following interventions could potentially reduce the perinatal mortality in the study population: screening and treating women with reactive syphilis serology; and management from early labour, by competent personnel in a health facility, of nulliparous women and multiparous women who are short or have a history of a perinatal death.

A community-based investigation of avoidable factors for maternal mortality in Zimbabwe.

A community-based investigation of maternal deaths was undertaken in a rural province (Masvingo) and an urban area (Harare) of Zimbabwe in order to assess their preventability. Avoidable factors were identified in 90 percent of the 105 rural deaths and 85 percent of 61 urban deaths. Delay in seeking treatment contributed to 32 percent and 28 percent of rural and urban deaths, respectively. Lack of transportation delayed or prevented access to healthy facilities in the rural area, a major problem in 28 percent of the cases studied. Suboptimal clinic and hospital management was identified in 67 percent and 70 percent of rural and urban deaths, respectively. Lack of appropriately trained personnel contributed to suboptimal care. In both settings, the severity of patients' conditions was frequently unrecognized, leading to delays in treatment and referral, and inadequate treatment. Appropriate community and health-service interventions to reduce maternal mortality are discussed.
