Ethnic differentials in early childhood mortality in Nepal.

This paper investigates the association of early childhood mortality (between birth and second birthday) with ethnicity in Nepal, based on data from the 1976 Nepal Fertility Survey, which was part of the World Fertility Survey. The approach is through a series of hazard models, which incorporate ethnicity, year of birth, mother's illiteracy, father's illiteracy, rural-urban residence, region, sex, maternal age, survival of previous birth, previous birth interval, and breast-feeding as covariates. Ethnic differentials in early childhood mortality are not explained by the other socioeconomic and demographic covariates, except for a modest effect of illiteracy, but the remaining covariates explain a great deal of variability in early childhood mortality itself. Analysis using an improved specification of breast-feeding as an age-varying covariate indicates, on average, that breast-feeding, relative to not breast-feeding, reduces age-specific mortality risks during the first 2 years of life by 76%, a very large effect.

Socioeconomic, demographic and environmental determinants of infant mortality in Nepal.

The Nepal Fertility and Family Planning Survey of 1986 demonstrated that demographic variables, previous birth interval and survival of preceding child, still predominated as determinants of infant mortality, particularly in rural areas of Nepal. However, in urban Nepal, where the level of socioeconomic development is higher, an environmental variable, along with previous birth interval and survival of preceding child emerges as important in determining infant mortality. Separate policy measures for child survival prospects in rural and urban Nepal are suggested.

Birth spacing and infant mortality: evidence for eighteenth and nineteenth century German villages.

Data from an historical population in which fertility control was minimal and modern health services were mostly unavailable are used to show that there appears to have been a strong association between previous birth interval length and infant mortality, especially when the previous child survived. Although only imperfect proxies for breast-feeding practices and other potentially confounding factors are available for this population, the results suggest that the association between previous interval length and infant mortality in this population is not solely, or primarily, a function of differences in breast-feeding behaviour or socioeconomic status. Other factors, e.g. maternal depletion or sibling competition, are more likely to explain the observed association.

Women's status and infant mortality in rural Colombia.

This paper investigates the effects of maternal demographic characteristics and social and economic statuses on infant mortality in rural Colombia. Demographic characteristics include the age of the mother, parity and length of preceding interbirth interval, and sex of infant. Measures of women's status at the time of birth include education, wage labor and occupation, economic stratum, place of residence, and whether the mother is living with a husband. The life history data for the study (involving 4,928 births) were collected in 1986 from a representative sample of two cohorts of women resident in rural central Colombia. Overall differentials in infant mortality by measures of women's status are small and are in good part associated with the differing reproductive behaviors of the women and variations in breastfeeding practices. The sharp declines in infant mortality recorded in rural Colombia in recent years appear less related to improved status of women than to reductions in fertility that enhance infant survivorship and to public health interventions shared by all segments of the population.

Maternal education as a modifier of the association between low birthweight and infant mortality.

Both low birthweight (LBW) and infant mortality rate (IMR) have been consistently shown to be associated with maternal level of educational attainment. This paper examines the mortality risk attributable to LBW in different levels of maternal education. Comprising the study population were 18,715 singleton live births to Jewish mothers ages 20-39, during the years 1977-1980 in the Negev (the southern part of Israel). Data were obtained from a linked record of birth and death certificates. As expected, proportions of LBW (less than 2500 grams) were inversely related to level of maternal education (12.2% in the lowest educational level, 7.9% and 8.0% in the two intermediate levels, and 7.2% in the highest educational level). The mortality risk attributed to LBW was found to be modified by maternal level of education. Mortality ratios standardized for maternal age and parity were computed, using educational level 3, where the lowest mortality rates were observed, as the standard population. Among LBW infants no significant differences were found across educational levels, except for the lowest educational level where only 69% of the expected number of deaths were observed. The survival advantage of LBW infants in the lowest educational level was observed both in the neonatal and the postneonatal periods. Among normal birthweight (NBW) infants, a statistically significant excess mortality was detected both in the highest and the lowest educational levels. The excess mortality of NBW infants in the highest level of maternal education was due to neonatal mortality (SMR = 2.2), while the excess mortality in this birthweight category in the lowest educational level occur mainly in the postneonatal period (SMR = 2.4).(ABSTRACT TRUNCATED AT 250 WORDS)

Epidemiology and cause of deaths among women in rural Bangladesh.

A total of 542 women aged 15 to 44 years died during the 10-year period 1976 to 1985 in the control area of Matlab, an area with a population of 90,000, representative of many other rural areas of southern Bangladesh. The corresponding age-specific mortality rate was 290 per 100,000 women 15-44 years. These deaths have been analysed retrospectively, using information collected through the Demographic Surveillance System set up by the International Centre for Diarrhoeal Disease Research, Bangladesh (ICDDR,B) and verbal autopsies conducted in the homes. Of these deaths, 175 (32%) were due to infectious diseases, 163 (30%) to direct obstetric complications, 67 (12%) to injuries, and the remaining 26% to other causes. Cause-specific and proportionate mortality rates showed a positive association with age for deaths due to infectious diseases, non-infectious diseases and unspecified causes, and an inverse association with age for deaths due to injuries. These rates showed a peak in the intermediate age group 25 to 34 years for deaths due to direct obstetric causes. No consistent trends were visible when annual rates were studied over time. Prior to death, 42% of the women were attended by traditional practitioners, and 33% were not attended at all. Demographic impact is discussed, emphasizing the contribution of obstetric causes to overall mortality. Priorities for health policy implications are proposed, focusing upon a strong maternity care programme, and improved availability of female health personnel, in the context of the socio-cultural constraints imposed on women in poor rural areas.

Levels and determinants of early neonatal mortality in Natal, northeastern Brazil: results of a surveillance and case-control study.

An institution-based surveillance and nested case-control study was conducted in Natal, Northeastern Brazil to estimate the level and determinants of early neonatal mortality. The early neonatal mortality rate was 25.5 per 1000 live-birth, 75% of early neonatal deaths were premature low birthweight infants, and the mortality rates were 591 and 318 per 1000 respectively, for preterm small for gestational age (PT-SGA) and preterm appropriate for gestational age (PT-AGA) infants. Mortality was 50 per 1000 for term low birthweight, and 8.6 for term normal birthweight AGA infants. In addition to prematurity and low birthweight, the main risk factors associated with early neonatal death were maternal smoking, complications during pregnancy or intrapartum, and inadequate antenatal care. The associations were weaker for prepregnancy factors such as single marital status or low maternal body weight, and no significant associations were observed with socioeconomic status. These findings suggest that in this population, efforts to reduce early neonatal death should focus on improved maternal care and the prevention of prematurity.

Perinatal mortality in Shanghai: 1986-1987.

The incidence of, and risk factors associated with, perinatal mortality in Shanghai during 1986-1987 are examined using data from a multi-site study conducted in 29 hospitals. The overall perinatal mortality rate was 14.96 per 1000 births. The mortality rates of antepartum fetal death, intrapartum fetal death and early neonatal death were 5.97, 2.06 and 6.94 per 1000 births, respectively. The perinatal mortality rates increased in winter and late spring. Male neonates were 1.5 times more likely to die than females. Low birthweight and preterm infants had 15 to 80 times higher risk of perinatal death. Higher parity, multiple pregnancy, and maternal age greater than or equal to 35 years were the risk factors for perinatal mortality. Asphyxia, cord complications, and congenital malformations were found to be the major causes of perinatal deaths. Comparison of mortality rates between Shanghai and the US suggests that the shortage of advanced technology in perinatal care (e.g. neonatal intensive care units) is a major obstacle to the reduction of perinatal mortality in Shanghai.

Neonatal mortality determinants in Jamaica.

The Jamaican Perinatal Survey included among its objectives the quantification of the island's neonatal mortality rate, the identification of the causes of these deaths (Wigglesworth Classification), and the determination of characteristics of both mother and infant that are associated with increased mortality. A death questionnaire was completed on babies who were born between September 1986 and August 1987, and who died in the neonatal period throughout the island of Jamaica. The neonatal mortality rate was 17.9 per 1000 live births with early and late rates of 16.0 and 1.9 per 1000, respectively. The major contributors to neonatal demise were prematurity and intrapartum asphyxia (74 per cent). Twins had a seven-fold greater risk of dying than singletons. Babies born to mothers under 15 years had a four-fold greater risk of dying than those of mothers 25-29 years. The neonatal mortality rate for Jamaica is high, with room for improvement, particularly in the prevention of perinatal asphyxia.

Determinants of maternal mortality in the developing world.

Maternal mortality is the culmination of a series of detrimental events in a woman's life, pregnancy being the last one. The underlying pathology is the lack of education, sanitation, accessible health care, as well as poor nutrition and poverty. These affect women during pregnancy and childbirth when they are more vulnerable. This 10-year review of literature from the developing world focuses on, and discusses the determinants of maternal mortality. Methods of reducing maternal mortality through policy addressing health care needs are touched on.

Maternal mortality in Ile-Ife, Nigeria: a study of risk factors.

The objective of this study was to determine which background factors predispose women to maternal mortality at the Obafemi Awolowo University Hospital in Nigeria. The study examined 35 cases of maternal death occurring in the hospital during the period 1 October 1989 to 30 April 1991. The control group comprised 35 women who were admitted to the hospital with similar complications during the same period, but who survived. Both cases and controls were investigated for their sociodemographic characteristics, their use of prenatal care, and the incidence of delay in clinical management. The results showed that the maternal deaths involved women who were younger and of poorer socioeconomic status than the women in the control group. Both groups showed an equal lack of prenatal care. However, a higher incidence of delayed treatment was found in the management of the cases of maternal deaths. Maternal mortality in the study population can be reduced through improved transportation and institutional management, and, on a long-term basis, through the adoption of measures to improve the socioeconomic status of women.

[Family planning and maternal and child care in present-day society].

The evidence is provided of a close relationship between the features of women's reproductive behaviour, their health status and the health of their children: the lack of rational planning child-birth results in increasing maternal and infant mortality rates, prematurity, birth of unwanted children. The use of abortions as one of the basic means of birth control produces a negative effect, i.e. they are a frequent cause of sterility, gynaecological diseases, complicated future pregnancies and deliveries. There is a description of the priority tasks and conditions for the effective introduction of family planning into the everyday life--the necessity of taking into account sociopsychological, regional aspects of birth control within a family, demographic situation at the local level; identification of women populations which are in need of family planning activities.

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.
