The study assessed the timing and causes of neonatal deaths in a rural area of Bangladesh. A population-based demographic surveillance system, run by the International Centre for Diarrhoeal Disease Research, Bangladesh, recorded livebirths and neonatal deaths during 2003-2004 among a population of 224,000 living in Matlab, a rural subdistrict of eastern Bangladesh. Deaths were investigated using the INDEPTH/World Health Organization verbal autopsy. Three physicians independently reviewed data from verbal autopsy interview to assign the cause of death. There were 11,291 livebirths and 365 neonatal deaths during the two-year period. The neonatal mortality rate was 32.3 per 1,000 livebirths. Thirty-seven percent of the neonatal deaths occurred within 24 hours, 76% within 0-3 days, 84% within 0-7 days, and the remaining 16% within 8-28 days. Birth asphyxia (45%), prematurity/low birthweight (15%), sepsis/meningitis (12%), respiratory distress syndrome (7%), and pneumonia (6%) were the major direct causes of death. Birth asphyxia (52.8%) was the single largest category of cause of death in the early neonatal period while meningitis/sepsis (48.3%) was the single largest category in the late neonatal period. The high proportion of deaths during the early neonatal period and the far-higher proportion of neonatal deaths caused by birth asphyxia compared to the global average (45% vs 23-29%) indicate the lack of skilled birth attendance and newborn care for the large majority of births that occur in the home in rural Bangladesh. Resuscitation of newborns and management of low-birthweight/premature babies need to be at the core of neonatal interventional packages in rural Bangladesh.Key words: Causes of death, Interventions, Neonatal mortality, Verbal autopsy, Bangladesh  相似文献

We describe a prospective cross-sectional survey over a 12-month period in the principal maternity hospital of Kathmandu, Nepal, where over 50% of the local population deliver. The study aim was to estimate the contribution of birth asphyxia to perinatal mortality in this setting. During 1995, there were 14,371 livebirths and 400 stillbirths, a total stillbirth rate of 27 per 1000 total births. The fresh term (2000 g or more) stillbirth rate was 8.5 per 1000 total births [95% CI 7.1, 10.1]. Ninety-two cases of neonatal encephalopathy (NE) affecting term infants were detected (excluding those due to congenital malformations, hypoglycaemia and early neonatal sepsis). The birth prevalence of NE was 6.4 per 1000 livebirths [95% CI 5.2, 7.8]. There was evidence of intrapartum compromise in 63 (68%) of the cases of NE and 65 (76%) of the stillbirths, but only in 12 (12%) of controls. The cause-specific early neonatal mortality rate for NE was 2.1 per 1000 livebirths [95% CI 1.4, 3.0]. Combining the NE deaths and fresh stillbirths gives an upper estimate for term birth asphyxia perinatal mortality rate of 10.8 per 1000 total births [95% CI 9.2, 12.6], 24% of all perinatal deaths before hospital discharge. This study suggests that birth asphyxia remains an important cause of perinatal mortality in developing countries. The paper discusses the pros and cons of different strategies to reduce birth asphyxia in low-income countries.  相似文献

Objectives An enhanced surveillance system that integrated health information systems and extended surveillance to previously uncovered areas to capture all births, perinatal and maternal deaths in a rural district of Pakistan was established in 2015, and this study uses capture–recapture methodology to assess completeness. Methods Births and deaths collected by the survey were matched with the data captured by the enhanced surveillance system. Capture–recapture methodology was used to estimate the total number of births and deaths, measure the degree of underestimation, and adjust mortality rates. Results Of all births, 99% were captured by the enhanced surveillance system. Ninety percent of neonatal deaths and 86% of early neonatal deaths were recorded. The recorded neonatal mortality rate was 40 per 1000 live births (95% CI 35–44), and after adjustment for under-enumeration was 42 per 1000 live births (95% CI 37–46). Recorded rates underestimated neonatal mortality by 5% and perinatal mortality by 7%. Five stillbirths were recorded by the survey and all were matched to recorded stillbirths. The one maternal death recorded by the survey was matched with the maternal death captured by the enhanced surveillance system. The maternal mortality ratio prior to adjustment for under-enumeration was 247 per 100,000 live births (95% CI 147–391), whereas after adjustment it was 246 per 100,000 live births (95% CI 146–389). Conclusion Application of capture–recapture methods to the enhanced surveillance system indicated a high completeness of birth and death recording by the surveillance system.  相似文献

The study was conducted to investigate the association between perinatal mortalityand factors relating to nutrition and infections in a rural population in northern Tanzania. A cohort of 3,618 women attending antenatal clinics was registered with background information and the results of antenatal examinations, and followed up after delivery. Stillbirths and neonatal deaths were identified and traced for an interview with the closest relatives. No information on outcome of pregnancy was obtained for seven women, and incomplete information was obtained for 99. The perinatal mortality rate was 27/1,000 births [95% confidence interval (CI) 22/1,000-33/1,000]; 44% were early neonatal deaths; and 56% were stillborn. There was an increased risk of perinatal death among babies with low birth-weight [for babies weighing 2,000-2,499 g, adjusted odds ratio (AOR) 5.8, 95% CI 2.1-15.8, babies below 2,000 g AOR 45.7; 95% CI 18.3-114.1], babies of women with a small arm circumference (below 23 cm, AOR 5.3, 95% CI 1.3-22.2), babies of women with positive VDRL serology (AOR 5.1, 95% CI 1.0-25.7), babies of mothers who had previously lost a baby (AOR 1.9, 95% CI 1.1-3.2), and among babies of nulliparous women (AOR 1.7; 95% CI 1.0-3.0). Infections and nutritional deficiencies should be addressed at antenatal clinics.  相似文献

Obstetric complications and newborn illnesses amenable to basic medical interventions underlie most perinatal deaths. Yet, despite good access to maternal and newborn care in many transitional countries, perinatal mortality is often not monitored in these settings. The present study identified risk factors for perinatal death and the level and causes of stillbirths and neonatal deaths in the West Bank and Gaza Strip. Baseline and follow-up censuses with prospective monitoring of pregnant women and newborns from September 2001 to August 2002 were conducted in 83 randomly selected clusters of 300 households each. A total of 113 of 116 married women 15-49 years old with a stillbirth or neonatal death and 813 randomly selected women with a surviving neonate were interviewed, and obstetric and newborn care records of women with a stillbirth or neonatal death were abstracted. The perinatal and neonatal mortality rates, respectively, were 21.2 [95% confidence interval (CI) 16.5, 25.9] and 14.7 [95% CI 10.2, 19.2] per 1000 livebirths. The most common cause (27%) of 96 perinatal deaths was asphyxia alone (21) or with neonatal sepsis (5), while 18/49 (37%) early and 9/19 (47%) late neonatal deaths were from respiratory distress syndrome (12) or sepsis (9) alone or together (6). Constraint in care seeking, mainly by an Israeli checkpoint, occurred in 8% and 10%, respectively, of 112 pregnancies and labours and 31% of 16 neonates prior to perinatal or late neonatal death. Poor quality care for a complication associated with the death was identified among 40% and 20%, respectively, of 112 pregnancies and labour/deliveries and 43% of 68 neonates. (Correction added after online publication 5 June 2008: The denominators 112 pregnancies, labours, and labour/deliveries, and 16 and 68 neonates were included; and 9% of labours was corrected to 10%.) Risk factors for perinatal death as assessed by multivariable logistic regression included preterm delivery (odds ratio [OR] = 11.9, [95% CI 6.7, 21.2]), antepartum haemorrhage (OR = 5.6, [95% CI 1.5, 20.9]), any severe pregnancy complication (OR = 3.4, [95% CI 1.8, 6.6]), term delivery in a government hospital and having a labour and delivery complication (OR = 3.8, [95% CI 1.2, 12.0]), more than one delivery complication (OR = 4.4, [95% CI 1.8, 10.5]), mother's age >35 years (OR = 2.9, [95% CI 1.3, 6.8]) and primiparity in a full-term pregnancy (OR = 2.6, [1.1, 6.3]). Stillbirths are not officially reportable in the West Bank and Gaza Strip and this is the first time that perinatal mortality has been examined. Interventions to lower stillbirths and neonatal deaths should focus on improving the quality of medical care for important obstetric complications and newborn illnesses. Other transitional countries can draw lessons for their health care systems from these findings.  相似文献

The perinatal mortality rate is still high in Belo Horizonte. This study investigated all 826 perinatal deaths taking place in 1999, focusing on the possibility of their prevention, using the Wigglesworth classification. The perinatal mortality rate was 20.2 per one thousand births, and the risk of perinatal death was 20 times higher in children with low birthweight. Some 24.6% of the children weighed more than 2,500g, and the main cause of death in this group was asphyxia during labor. The antepartum cause of death contributed to 30% of all deaths, and 25% of these children weighed more than 2,500g. Some deaths occurred out of hospital, and in some cases the mother arrived at hospital in end-stage labor. About 40% of all perinatal deaths or 60% of all early neonatal deaths could have been prevented, suggesting flaws in prenatal, intrapartum, and neonatal care at both the clinical and health-care organizational levels. To intervene in this situation, progress is needed in improving quality of care and ensuring accountability in the specific health services and the health care system as a whole.  相似文献

Peri- and neonatal mortality remain high in developing countries, especially in sub-Saharan Africa. In the present study, we quantified and identified the most important predictors of early mortality in rural Malawi. Data were obtained from a community-based cohort of 795 pregnant women and their 813 fetuses, followed prospectively from mid-pregnancy. In this group, peri- and neonatal mortality rates were 65.3 deaths per 1000 births and 37.0 deaths per 1000 live births respectively. When controlled for month of birth, maternal age and selected socio-economic variables, preterm birth was the strongest independent predictor of both peri- and neonatal mortality (adjusted odds ratios 9.6 for perinatal and 11.0 for neonatal mortality; 95% confidence intervals: [4.4, 21.0] and [3.7, 32.7] respectively). Weaker risk factors for mortality included a maternal history of stillbirth and abnormal delivery. Preterm delivery was associated with primiparity and peripheral malaria parasitaemia of the mother, and it accounted for 65% of the population-attributable risk for perinatal and 68% of the neonatal mortality. Successful intervention programmes to reduce peri- and neonatal mortality in Malawi have to include strategies to predict and prevent prematurity.  相似文献

U.S. preliminary data for 2002 show a significant increase in the infant mortality rate to 7.0 infant deaths per 1,000 live births, the first rise in the infant mortality rate since 1958. The increase in infant mortality was concentrated in the neonatal period, particularly in deaths occurring within seven days of birth. Partially edited fetal death data suggest that the increase in neonatal mortality was accompanied by a decline in the late fetal mortality rate, and thus it appears that the 2002 perinatal mortality rate will remain level. Potential explanatory factors for the changes in the infant mortality rate are examined, including causes of infant death, percentage of births that are preterm, and low birthweight. Data from the 2002 linked birth and infant death file will allow an assessment of the contribution of maternal and infant factors such as multiple births and management of labor and delivery.  相似文献

A multicentre study of perinatal mortality in Nepal   总被引:1,自引:0,他引:1  
Summary. A prospective survey was carried out in two Kathmandu hospitals and two rural districts to establish urban and rural perinatal mortality rates (PNMRs) for these four centres in Nepal and to ascertain the causes of perinatal mortality. All perinatal deaths occurring over a 1-year period in the four centres were included (during which time there was a total of 14 967 births). Cause of death was established by contemporary review of hospital case records or by structured questionnaire ('verbal autopsy') in the rural areas. The PNMRs in the hospitals were 48.0 and 23.7 per thousand total births respectively, whilst those of the rural settings were 96.2 and 42.5 per thousand births. Perinatal asphyxia, low birthweight and infection were the most common causes but many of the deaths were unexplained. The high mortality rates were felt to reflect the difficult circumstances of childbirth in Nepal. It was concluded that a number of interventions would appear appropriate, but that these should be introduced in a scientific manner.  相似文献

BACKGROUND: Low birthweights as well as high perinatal mortality rates are common in most African populations. Little is known, however, about how low birthweight corresponds with higher mortality rates within African populations. Twins are known to have lower birthweights and higher perinatal mortality rates than singletons. If lower birthweights represent higher perinatal risk per se, small twins within a population with generally lower birthweights should have critically increased risks. METHODS: In total, 15,255 births in a Tanzanian hospital during 1999-2006 were analysed to determine birthweight distribution and examine perinatal mortality rates (including stillbirths and neonatal deaths within 24 hours) by birthweight in twins and singletons. Referral births from outside the district where the hospital was situated were excluded from analysis. RESULTS: The mean birthweight for births within an estimated normal distribution was 3172 g, with a standard deviation of 462 g. The overall perinatal mortality rate was 43.9 per 1000 births (95% confidence interval: 40.7-47.2). Perinatal mortality rates among twins and singletons were 91.0 and 41.1 per 1000 babies respectively, corresponding to a relative risk of 2.2 (95% confidence interval: 1.7-2.8). The birthweight distribution for twins was shifted to lower birthweights. Twins had a generally lower birthweight and an excess of extremely small births as compared to singletons. The increased mortality rate for twins appeared to be independent of birthweight. CONCLUSIONS: The two-fold increased risk of perinatal death for twins was observed across the whole birthweight distribution, and very small twins appeared to have an excess perinatal risk that was almost similar to that of larger twins.  相似文献

This article focused on risk factors for neonatal and post-neonatal mortality by linking live births and infant death records. The study was conducted in the municipality of Goiania, in the Central-West region of Brazil. A total of 20,981 live births and 342 infant deaths constitute the retrospective cohort. Neonatal and post-neonatal mortality risks were estimated in this cohort study of live births by logistic regression. In the neonatal period, the highest ORs were for delivery in public hospitals (OR = 2.28; 95% CI 1.57-3.32), pre-term neonates (OR = 8.94; 95% CI 5.85-13.67), and low birth weight (OR = 8.92; 95% CI 5.77-13.79). Cesarean delivery appeared as a protective factor (OR = 0.58; 95% CI 0.43-0.78). For post-neonatal mortality, the highest ORs were for illiterate mothers (OR = 6.25; 95% CI 1.25-31.27), low birth weight (OR = 3.12; 95% CI 1.67-5.84), and delivery in public hospitals (OR = 2.65; 95% CI 1. 13-6.23). The linkage identified socioeconomic variables that were more important risk factors for post-neonatal than neonatal mortality.  相似文献

The causes of perinatal mortality among 7392 hospital births which occurred in Pelotas, RS, Brazil during 1982, were analyzed using the simplified classification described by Wigglesworth. The main advantage of this classification is that it can be used even in places where postmortems are seldom performed. The perinatal deaths were classified into 5 groups: a) macerated fetuses without malformations; b) congenital malformations; c) immaturity; d) asphyxia, and e) other causes of death. The perinatal mortality rate was 33.7/1000 births, nearly equally divided between fetal and early neonatal deaths, and 8.8% of the babies were of low birthweight. 36% of the perinatal deaths were antepartum stillbirths, and 60% of these weighed 2000 g or more. The 2nd most important cause was immaturity, which accounted for 31% of the deaths. In this latter group, 21% weighed 2000 g or more at birth. These findings, as well as the high birthweight-specific perinatal mortality rates, strongly suggest that there are deficiencies in the antenatal and delivery care in Pelotas that must be corrected promptly. Policies that should be implemented by health planners include: decentralization of antenatal care clinics; utilization in these clinics of the "at-risk" concept to identify women at high risk of delivering low birthweight babies, efforts to increase community participation and home visits in order to attract those pregnant women who do not attend clinics. In addition, it is mandatory that well-trained doctors (obstetricians and pediatricians) should be available 24 hours/day at the maternity hospitals to assist mothers and babies identified as being at high risk.

More than 50% of infant deaths in India occur during the neonatal period. High priority therefore needs to be given to improving the survival of newborns. A large number of neonatal deaths have their origin in the perinatal period and are mainly determined by the health and nutritional status of the mother, the quality of care during pregnancy and delivery, and the immediate care of the newborn at birth. Main causes of neonatal mortality are birth asphyxia, respiratory problems, and infections, especially tetanus. Most such deaths occur among low birthweight babies. Hypothermia, undernutrition, and mismanaged breast feeding may also indirectly contribute to neonatal mortality. Community-based studies have, however, demonstrated that most neonatal mortality can be affordably prevented through primary health care. Efforts are underway to expand the health care infrastructure, but the outreach of maternal and child health care remains unsatisfactory especially in rural areas.  相似文献

Summary. Perinatal deaths occurring in the Campania region of southern Italy in 1982 were analysed. The perinatal mortality rate was 17.6 per thousand (stillbirth rate 8.3, early neonatal mortality rate 9.3). Compared with Swedish data, our deaths excess does not seem attributable to an unfavourable birthweight distribution, but to high birthweight mortality rates in every birthweight category and particularly in the normal birthweight group (>2500 g). This group of newborns, representing about 94% of the births, contributes 45.4% of perinatal deaths; this situation is not common in developed countries, where the normal birthweight newborns form a much smaller proportion of perinatal deaths. The analysis of the causes of perinatal mortality, even though autopsies are rarely executed in Campania, shows a high prevalence of events which should be prevented by good antenatal and perinatal care.  相似文献

Perinatal mortality refers to stillbirths and deaths which occur during the first week of life. 7 million such deaths occur annually worldwide, almost all of which are in developing countries. Rates as high as 75-100 deaths/1000 births have been documented in developing countries. The 3 leading causes of perinatal mortality are complications of pre-term birth, birth asphyxia and birth trauma, and bacterial infections. The other causes of perinatal mortality are largely unknown due to difficulties in documenting stillbirths in developing countries. In many developing country societies, it is culturally unacceptable to acknowledge a birth until it has survived its first week of life. This study identified and quantified the risk factors for perinatal deaths in a rural community in Manikganj district, Bangladesh. Cases were mothers whose infants died in the perinatal period, while comparison mothers were those whose infants survived the perinatal period. Of the 186 infant deaths recorded, 130 (69.9%) were in the perinatal period, and included 53 stillbirths. The perinatal death rate was 64.5/1000 births. Logistic regression confirmed that maternal age, parity, and mal-presentation were significantly associated with perinatal deaths. Mal-presentation was independently associated with a increased risk of perinatal death.  相似文献

Population-based estimations of perinatal and neonatal outcomes are sparse in Vietnam. There are no previously published data on small for gestational age (SGA) infants. A rural population in northern Vietnam was investigated from 1999 to 2005 (n=5521). Based on the birthweight distributions within the population under study, reference curves for intrauterine growth for Vietnamese infants were constructed and the prevalence and distribution of SGA was calculated for each sex. Neonatal mortality was estimated as 11.6 per 1000 live births and the perinatal mortality as 25.0 per 1000 births during the study period. The mean birthweight was 3112 g and the prevalence of low birthweight was 5.0%. The overall prevalence of SGA was 6.4%. SGA increased with gestational age and was 2.2%, 4.5% and 27.1% for preterm, term and post-term infants, respectively. Risk factors for SGA were post-term birth: adjusted odds ratio (AOR) 7.75 [95% CI 6.02, 9.98], mothers in farming occupations AOR 1.72 [95% CI 1.21, 2.45] and female infant AOR 1.61 [95% CI 1.27, 2.03]. There was a pronounced decrease in neonatal mortality after 33 weeks of gestation. Suggested interventions are improved prenatal identification of SGA infants by ultrasound investigation for fetal growth among infants who do not follow their expected clinical growth curve at the antenatal clinic. Other suggestions include allocating a higher proportion of preterm deliveries to health facilities with surgical capacity and neonatal care.  相似文献

Perinatal mortality in Shanghai: 1986-1987.   总被引:1,自引:0,他引:1  
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.  相似文献

BACKGROUND/OBJECTIVES: A population-based retrospective cohort study of triplet pregnancies was conducted to estimate individual probabilities of neonatal mortality (death within 28 days of birth) conditional on the number of neonatal deaths experienced by other infants in the triplet set. METHODS: Data on 4,697 triplet sets (14,091 births) were derived from the U.S. 1995-1997 matched multiple birth file assembled by the National Center for Health Statistics. Response conditional multivariate logistic regression was used to model the association of neonatal mortality among cotriplets. To account for the correlation of the outcomes among cotriplets, regression parameters were estimated by the methodology of generalized estimating equations with robust variance estimates. RESULTS: Compared with a triplet where both cotriplets survived the neonatal period, the adjusted odds ratio and 95% confidence interval (CI) for a neonatal death associated with one and two cotriplet neonatal deaths were 1.80 (95% CI 1.06, 3.04), and 13.41 (95% CI 2.31, 77.7), respectively, after adjusting for birthweight and gestational age. CONCLUSIONS: These results show strong evidence of clustering of neonatal deaths in triplet pregnancies.  相似文献

Purpose: We examined the association between rural residence and birth outcomes in older mothers, the effect of parity on this association, and the trend in adverse birth outcomes in relation to the distance to the nearest hospital with cesarean‐section capacity. Methods: A population‐based retrospective cohort study, including all singleton births to 35+ year‐old women in British Columbia (Canada), 1999‐2003. We compared birth outcomes in rural versus urban areas, and between 3 distance categories to a hospital (<50, 50‐150, >150 km). Outcomes included labor induction, cesarean section, stillbirth, perinatal death, preterm birth (<37 weeks), small‐for‐gestational‐age, large‐for‐gestational‐age, and neonatal intensive care unit admission. We used multivariate regression to obtain adjusted odds ratios (ORs) and 95% confidence intervals (CIs). Findings: Among the 29,698 subjects, 11.5% lived in rural areas; 5% lived within 50‐150 km; and 1.1% lived >150 km from a hospital. Rural women were at lower risk of primary and repeat cesarean section (OR = 0.9, CI: 0.9‐1.0; OR = 0.7, CI: 0.6‐0.9) and small‐for‐gestational‐age (OR = 0.8, CI: 0.7‐0.9) births; they were at increased risk for perinatal death (OR = 1.5, CI: 1.1‐2.1) and large‐for‐gestational‐age (OR = 1.1, CI: 1.1‐1.2) births. The association was stronger among multiparous versus primiparous women. No differences in emergency cesarean section, preterm birth, or neonatal intensive care admission were found, regardless of parity. Perinatal mortality increased with distance from hospital; OR = 1.5 (CI: 1.1‐2.1) per distance category. Conclusions: Older women in rural versus urban areas had a lower rate of cesarean section and increased risk of perinatal death. The risk of perinatal death increased with the distance to hospital. Further studies need to evaluate the contribution of underlying perinatal risks, access to care, and decision making regarding referral and transport.  相似文献
