Maternal and perinatal mortality due to eclampsia

Forty-four mothers with eclampsia and their newborns managed during the year 1988 at the University Hospital of Banaras Hindu University, Varanasi were analyzed. The incidence of eclampsia was 2.2% of all hospital deliveries. Eclampsia was more common in women (below 20 years) and at gestation of 36 weeks and below, and amongst the mothers deprived of antenatal care. The maternal mortality amongst cases of eclampsia was 31.8% and perinatal loss was 38.6%. A relatively high incidence of eclampsia and maternal and perinatal loss was considered to be related to lack of antenatal care and late referral to the hospital. Our findings suggest that more frequent use of properly timed cesarean section can improve the maternal outcome.

Study of infant and childhood mortality in an ICDS block of eastern U.P

Information on births and deaths was collected in 11 randomly selected AWW areas of Barhaj Mahen ICDS project area in Eastern U.P. by an independent survey team in 1988-89. The findings revealed that the births and deaths were under-reported to the tune of 36.6 and 13.9 percent respectively, by AWWs. The different demographic indicators generated from the data were as follows, CBR and CDR were 30.3 and 7.1 per 1000 population. Neonatal mortality rate, IMR, and MMR were 58.3, 74.7 and 6.5 per 1000 live births. 0-6 yr mortality was 16.3 per 1000 children and constituted 37.5% of the total deaths. ARI, diarrhoea and fever were the major causes of mortality in 0-6 yr old children accounting for 25.9, 22.3 and 14.8% respectively. The findings indicated that there was underreporting in adult mortalities despite the independent investigation, and a reduction in infant and childhood mortality possibly due to the beneficial effect of ICDS services.

Postpartum haemorrhage in Zimbabwe: a risk factor analysis

OBJECTIVES

To identify risk factors associated with postpartum haemorrhage (PPH) in order to improve the effectiveness of antenatal screening.

DESIGN

A population-based case control study.

SETTING

Harare, Zimbabwe.

SUBJECTS

Two groups of women, one group consisting of those with postpartum haemorrhage after a normal vaginal delivery and the other of women with normal unassisted vaginal delivery without PPH.

METHOD

Data abstracted from the medical records; relative risks were estimated by multivariate logistic regression.

RESULTS

Low parity, advanced maternal age, and antenatal hospitalisation were among the strongest risk factors, with more modest associations for history of poor maternal or perinatal outcomes and borderline anaemia at the time of booking. No association with grand multiparity was found.

CONCLUSIONS

These findings confirm the importance of previously recognised factors such as low parity, poor obstetric history, anaemia, and prolonged labour, but call into question the significance of grand multiparity. Previously undocumented factors such as maternal age greater than 35 years and occiput posterior head position emerged as predictors worthy of further investigation.

High perinatal and neonatal mortality in rural India

A prospective study conducted in rural India on pregnant women showed poor utilization of primary health services and very poor maternal care receptivity especially in terms of antenatal care. A very high perinatal mortality rate of 81.3/1000 live births and a neonatal mortality rate of 63.7/1000 live births was observed in the present study. Out of 204 live births, 72.05% of newborn developed complications within 6 weeks of the delivery. Most of the complications were of a minor nature and could be attributed to poor environmental conditions, lack of personal hygiene and ignorance. The study highlights the need for training of grass root level workers for the improvement of perinatal and neonatal care in rural India.

Neonatal tetanus mortality in coastal Kenya: a community survey

In a house-to-house survey in Kilifi District, Kenya, mothers of 2556 liveborn children were interviewed about neonatal mortality, especially from neonatal tetanus (NNT). The crude birth rate was 60.5 per 1000 population, the neonatal mortality rate 21.1 and the NNT mortality rate 3.1 per 1000 livebirths. The neonatal and NNT mortality rates were higher in boys than in girls. Neonatal tetanus was not associated with mother's age, parity, or history of previous child death. The majority of the children (72%) were adequately protected at birth against NNT; in those with documented protection NNT mortality was 0, in those with undocumented protection 1.2 and in other children 8.5 per 1000 livebirths. Other risk factors for NNT included home delivery, untrained assistance during delivery, unhygienic cord cutting and application of potentially infectious substances on the umbilical stump. The survey indicates that over the past decade the surveyed area has greatly reduced neonatal and NNT mortality. Possible strategies for accelerated NNT control have been identified by the survey.

Hypertension during pregnancy in Africa and infants' health. A cohort study in an urban setting

The objective of the study was to assess the prevalence of unclassified hypertension during pregnancy and its consequences on infant's health in an African urban setting: Pikine, a suburb of Dakar, Senegal. A cross-sectional study of a random sample of pregnant women and a prospective study, from the inclusion to seven days after delivery, were performed. 886 women attending the prenatal centers were included in the cross-sectional study. 471 pregnant women were included in the follow-up study. The prevalence of DBP > or = 120 mmHg was 0.7%; 5.7% of the women had DBP > or = 95 mmHg. Longitudinal data were available for 425 deliveries. Two spontaneous abortions, 25 stillbirths, and 12 deaths during the early neonatal period were recorded. Among babies living at birth, the percentage of LBW (> or = 2500 g) was 8.5%. The percentages of adverse outcome of pregnancy (death and/or low birth weight) was associated with mothers' diastolic BP: < 85 mmHg: 13%; 85 to 89: 16%; 90 to 94: 9%; DBP > or = 95: 32%, (p < 0.01). Using 95 mmHg as a cutpoint, the relative risk of adverse outcome associated with a DBP > or = 95 mmHg was 2.5 (CI 95%: 1.4-4.3). This risk was significantly increased among women who reported difficult living conditions. Eight percent of the adverse outcomes of pregnancy, 10% of the low birth weights and 8% of the perinatal mortality were found to be associated with DBP > or 95 mmHg.

Syphilis-associated perinatal and infant mortality in rural Malawi

In Mangochi District, a rural area of Malawi, the prevalence of active syphilis was 3.6% among 3591 women who had singleton births and who were negative for human immunodeficiency virus (HIV). Compared with non-syphilitic women, those with active syphilis (positive Venereal Disease Research Laboratory/rapid plasmin reagin tests (titre > or = 1:8) and a reactive microhaemagglutination assay) were more likely to experience stillbirths as well as the early and late neonatal deaths and even postneonatal deaths of their children. Characteristics associated with active syphilis were not very useful in targeting women at high risk of having the condition, which makes universal screening in antenatal programmes the most efficacious way to prevent syphilis-associated morbidity and mortality. The potential for a programme to prevent congenital syphilis in the perinatal, neonatal, and post-neonatal periods is evident. In considering resource allocation to child survival programmes in areas where the prevalence of syphilis is high, officials need to include antenatal syphilis screening, using rapid tests and treatment at the first contact of the mother with the health care system.

Comparative outcome of low birth weight babies

One hundred and fifty six babies with birth weight between 1500-2000 g and 103 full term-appropriate for gestational age (FT-AGA) babies delivered at University Hospital, District Hospital and village homes were included for a comparative study of mortality, morbidity and growth pattern. The low birth weight (LBW) babies from the three centres had similar birth weight and gestational age. Neonatal mortality rates for the LBW babies were similar at the three centres. The main cause of death were infections and aspiration with rates again being similar. Diarrhea and respiratory tract infections were common causes of morbidity. The mortality rates for the LBW babies were significantly higher as compared to FT-AGA babies irrespective of the place of delivery. The incidence of morbidities like diarrhea and respiratory infections were also higher in LBW babies. However, the differences were statistically significant mostly in the preterm group. The weight gain of all LBW babies was similar up to 3 months of age. The findings of an identical outcome for the LBW babies at village level to those managed at hospitals is an encouraging trend to increasing domiciliary care for LBW babies.

Observations from a cluster survey on seasonality in neonatal tetanus

This report presents the observations on seasonality and neonatal tetanus (NNT) mortality from a cluster survey on NNT mortality conducted in Kano metropolis, Northern Nigeria. A two stage cluster sampling method was used for the survey. There were 2,623 live-births with 1778 (67%) occurring in the dry season (October-May). The NNT mortality rate was 20.6/1000 live-births. The magnitude of neonatal mortality and NNT mortality were 47.3 and 30.8 per 1000 live-births respectively for the wet season. These were much higher than the comparative figures for dry season. There was, however, no significant association between seasonality and NNT mortality since the same trend was observed for non-NNT deaths.

Neonatal tetanus estimates of mortality derived from a cluster survey in northern Nigeria

A two-stage cluster survey of deaths from neonatal tetanus (NNT) was carried out in Kano metropolis, Northern Nigeria in order to estimate the mortality from the disease. Estimates of mortality were obtained by three different methods which were compared. According to clinical diagnosis, mortality was 20.6/1000 live-births while reports of 4-14 day deaths gave a figure of 11.4/1000 live-births. From information volunteered by informants, it appeared to be only 4.6/1000 live-births. NNT accounted for 68% neonatal deaths. The sex-specific mortality rates were 23.4 and 17.9 per 1000 live-births for males and females respectively. There was, however, no significant association between sex and death from neonatal tetanus. The mortality for the first 6 months of recall period was 15.2/1000 live-births and 24.2/1000 live-births for the last 6 months. There was also no significant association between recall period and death. In view of the markedly different estimates by the various methods of diagnosis, retrospective clinical diagnosis is suggested for community-based surveys of mortality related to neonatal tetanus.

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.

Preceding birth intervals and child survival: searching for pathways of influence

The importance of the length of preceding birth intervals for the survival chances of young children has been established, but the debate concerning the causal biomedical or behavioral mechanisms continues. This article uses data from 17 Demographic and Health Surveys to investigate the effect of birth intervals on child mortality: Anthropometry of children, recent morbidity of children, and use of health services are examined in addition to child survival data for children born in the five years before the survey. Various methodological approaches are used to investigate the relative importance of the postulated mechanisms linking birth intervals and child survival. Short preceding birth intervals are associated with increased mortality risks in the neonatal period and at 1-6 months of age, and, to a much lesser extent, at 7-23 months of age. The effects of short birth intervals on nutritional status are rather moderate, and there is a weak relationship with lower attendance at prenatal care services. No consistent relationship exists between the length of birth intervals and other health status or health-service utilization variables. The results indicate that prenatal mechanisms are more important than postnatal factors, such as sibling competition, in explaining the causal nature of the birth interval effect.

Urinary-tract infections in African neonates

During a 4-year period between January 1987 and December 1990, 41 high-risk neonates with proven urinary tract infections (UTIs) were studied prospectively and compared with 55 control neonates. An incidence of 2.6 UTIs per 1000 live births was noted, amongst whom no obvious radiological abnormalities of the urinary tract were found. Significantly, more males than females developed UTIs, the ratio being 4.5:I. Low-birth-weight babies were significantly more often affected than those of normal weight (P less than 0.05). Staphylococcus aureus and Klebsiella spp. were the predominant pathogens isolated. Aetiologically, bacteraemia from sepsis was important. Most of the infants presented with a significantly higher incidence of pyrexia, abdominal distension, lethargy and jaundice (P less than 0.01). The overall mortality rate of 17.1% was closely related to these associated problems. The relatively high incidence of UTI and the rarity of radiological abnormalities of the urinary tract in the African neonate contrast with previous reports in the literature and the reason is worthy of consideration. Despite the rarity of urinary-tract anomalies, a continuous surveillance of the trend of neonatal UTI and its outcome is recommended.

Neonatal morbidity and mortality at Kenyatta National Hospital newborn unit

A six month prospective study of neonatal morbidity and mortality of the newborn unit (NBU) at Kenyatta National Hospital is presented. Of the 126 infants delivered in the maternity unit, 967 (30%) ended up in the NBU and 562 (59.8%) were low birth weight (LBW); 79.3% were appropriate for gestational age (AGA), 19.9% were small for gestational age (SGA) while 1.8% were large for gestational age (LGA). The infants with birth weight of < 1500 g and gestation < 32 weeks had the worst prognosis with a mortality of 51.3% and 64.6% respectively. The major causes of morbidity and mortality were immaturity, respiratory distress, infections and perinatal asphyxia. The majority of the deaths (86.8%) occurred within the first week of life. The overall neonatal mortality for this period was 24.6%, but 95.6% of the deaths were preterm while LBW in general contributed to 93.5% of the deaths.

Health effects of consanguinity in Pondicherry

Of 1000 pregnant women studied, consanguinity was observed in 30.8%, with a higher frequency among women from rural areas, and among Hindus. In the consanguineous group, first cousin marriages were present in 47.4%, and uncle niece marriages in 23.4% of women. Coefficient of inbreeding was highest in Harijans (0.0258), followed by non-Brahmins (0.0220) and Brahmins (0.0204). Fertility was not influenced by consanguinity. There was a significantly higher rate of still births and infant mortality in consanguineous matings as compared with non-consanguineous. Total morbidity was higher in the consanguineous group as compared with the non-consanguineous (p less than 0.01), especially that due to neonatal infections and jaundice. There was no significant difference in the prevalence of congenital malformations, chromosomal and genetic disorders between the two groups, although the number of abnormal births in this group was small.

Infant and child mortality in rural Egypt

This research examines determinants of infant and child mortality in rural Egypt, primarily the effects of household economic status and the availability of health services. Certain features of the health service environment affect survival in the neonatal period. In early childhood, survival chances improve markedly as income increases and if the household depends almost exclusively on employment income. In infancy and in early childhood, mortality is strongly associated with region of residence and maternal demographic characteristics, and is weakly associated with parental schooling.
