The postponement of neonatal deaths into the postneonatal period: evidence from Massachusetts

Part of the slow decline in the postneonatal mortality rate and the rapid decline in the neonatal mortality rate during the 1970s may have been due to a postponement of some neonatal deaths into the postneonatal period. The authors hypothesized that any such postponement should be accompanied by a lack of decline, or even an increase, in late neonatal and postneonatal mortality rates among low birth weight babies and babies dying of conditions originating in the perinatal period. To examine this theory, the authors used vital records data to compare infant mortality rates in Massachusetts during 1970-1972 with rates during 1978-1980. Log-linear hazard models were used to calculate death rates, while controlling for changes in maternal age, race, education, and prior reproductive history. The authors found that babies of birth weight under 1,500 g had no decline in late neonatal mortality rates and babies of birth weight under 2,500 g had no decline in postneonatal mortality rates. Babies of birth weight 500-999 g had an increased postneonatal mortality rate (rate ratio = 2.4; 95% confidence limits = 1.0-5.4). These unimproved or increased death rates were due in part to conditions originating in the perinatal period. The authors conclude that, although infant mortality rates have declined, this postponement was real, and that efforts to monitor infant mortality will benefit from its routine quantification.     

Neonatal mortality due to preterm birth at 28-36 weeks' gestation in China, 2003-2008

Almost all (99%) neonatal deaths occur in developing countries, where the progress in reducing neonatal mortality rates (NMR) has been small; the Millennium Development Goal for child survival cannot be met if this situation continues. China is among the 10 countries that have the largest numbers of neonatal deaths. In order to provide effective interventions to reduce the national NMR for government policy makers, we analyse the trends, causes and characteristics of the neonatal deaths of preterm babies in different regions of China during the period 2003-2008. The data for this retrospective study were retrieved from the population-based Maternal and Child Health Surveillance System of China. The Cochran-Armitage trend test was used to analyse the trend of NMRs due to immaturity. The national NMR due to immaturity has decreased by 38.7% in 6 years. However, the proportion of preterm births among the causes of neonatal death has increased significantly from 33.6% in 2003 to 40.9% in 2008. The relative risk of neonatal death among preterm babies has shown significant regional disparity. In 2008, the adjusted relative risk was 1.30 [95% confidence interval (CI) 0.95, 1.78] in the inland regions and 2.37 [95% CI 1.56, 3.60] in the remote regions, both compared with the coastal regions. The proportion of neonatal deaths with a gestational age <32 weeks or a birthweight <1500 g was highest among the coastal regions. Most neonatal deaths of preterm babies in remote areas were born at home and were not treated before death. Our study suggests that preterm birth is the leading cause of neonatal death in China and neonatal mortality due to immaturity displayed regional differences. The Chinese government should implement major effective strategies for reducing the mortality of preterm infants to further decrease the total NMR. Priority interventions should be region-specific, depending on the availability of economic and health care resources.

The role of medicine in the decline of post-War infant mortality in Japan

The infant mortality rate (IMR) in Japan declined dramatically in the immediate post-War period (1947-60) in Japan. We compared the time trends in Growth Domestic Product (GDP) in Japan against declines in IMR. We then conducted a prefecture-level ecological analysis of the rate of decline in IMR and post-neonatal mortality from 1947 to 1960, focusing on variations in medical resources and public health strategies. IMR in Japan started to decline after World War II, even before the era of rapid economic growth and the introduction of a universal health insurance system in the 1960s. The mortality rates per 1000 infants in 2009 were 2.38 for IMR, 1.17 for neonatal mortality and 1.21 for post-neonatal mortality. The rate of decline in IMR and preventable IMR (PIMR) during the post-War period was strongly correlated with prefectural variations in medical resources (per capita physicians, nurses, and proportion of in-hospital births). The correlation coefficients comparing the number of physicians in 1955 with the declines in IMR and PIMR from 1947 to 1960 were 0.46 [95% confidence interval (CI) 0.19, 0.66] and 0.39 [95% CI 0.11, 0.61], respectively. By contrast, indicators of public health strategies were not associated with IMR decline. The IMR in Japan has been decreasing and seems to be entering a new era characterised by lower neonatal compared with post-neonatal mortality. Furthermore, the post-War history of Japan illustrates that improvement in infant mortality is attributable to the influence of medical care, even in the absence of rapid economic development.     

Infant mortality in Newark,New Jersey. A study of sociodemographic and medical factors.

Newark, a metropolitan industrial town, experienced the highest infant mortality of any major city in the United States in the 1960s and early 1970s. Between 1970 and 1973, however, infant mortality among non-whites in this city declined strikingly. This decline could not be directly related to declines (a) in birth rates, (b) in the proportions of babies of low birth weight, (c) in the proportions of babies born to mothers in unfavorable age groups, (d) in the general fertility rates, or (e) in the illegitimacy rates. The decline may have been related (a) to the removal from childbearing cohorts of the group of females in the population--as yet undefined--whose babies would have been at high risk of infant mortality, (b) to the falling birth rate, (d) to better postnatal care--or to all of these factors. The study data suggest a multifactorial basis for the precipitous decline and also suggest that further major reductions in infant mortality among both nonwhites and whites will require better definition of the causes of low birth weight.     

Harsh social conditions and perinatal survival: an age-period-cohort analysis of the World War II occupation of Norway.

OBJECTIVES. The hypothesis was tested that unfavorable social conditions are associated with poor perinatal survival through direct effects on pregnancy or, more indirectly, through effects on mothers born under such conditions. The occupation of Norway by Nazi Germany was used as a period of social hardship. METHODS. Data from Norwegian vital statistics and the Medical Birth Registry were used to describe perinatal mortality during World War II and also a generation later, among babies born to mothers who had themselves been born during the war. Logistic regression was used to identify a possible cohort effect among mothers born in 1940 through 1944 compared with mothers born before or after that period. RESULTS. Harsh conditions in Norway during the occupation increased childhood mortality. However, perinatal mortality declined during that period. Likewise, no adverse effect was seen on the survival of babies born to mothers who had themselves been born during the war (odds ratio = 1.00; 95% confidence interval = 0.96, 1.04). CONCLUSIONS. We find no evidence that wartime conditions in Norway impaired perinatal survival, either directly or through an effect on women born during the war. These data underscore how little is known about the ways that social conditions influence perinatal mortality.     

Trends in preterm birth and neonatal mortality among blacks and whites in the United States from 1989 to 1997

Preterm birth, a major determinant of infant mortality, has been increasing in recent years. The authors examined trends in preterm birth and its determinants by using the US birth and infant death files for 1989-1997. The impact of trends in preterm birth rates on neonatal and infant mortality was also evaluated. Among Whites, preterm births (<37 completed weeks of gestation) increased from 8.8% of livebirths in 1989 to 10.2% in 1997, a relative increase of 15.6%. On the other hand, preterm births among Blacks decreased by 7.6% (from 19.0% to 17.5%) during the same period. An increase in obstetric interventions contributed to increases in preterm births for both races but was outweighed by other unidentified favorable influences for Blacks. Neonatal mortality among preterm Whites dropped 34% during the 8 years of the study, while the decrease was only 24% among Blacks. This large disparity countered the changes in preterm birth rates so that the percentage decline in neonatal mortality was similar in the two racial groups (18-20%). In conclusion, the anticipated mortality benefit from a lower preterm birth rate for Blacks has been blunted by suboptimal improvement in mortality among the remaining preterm infants. The widening race gap in mortality among preterm infants merits attention.     

Survival after peptic ulcer perforation: A time trend analysis

The survival of 1098 patients with ulcer perforation in Norway during the period 1952–1990 was compared with expected survival. Cox regression models incorporating population mortality rates, were used to analyse effects of sex, age, year of birth, and year at risk on excess mortality. Survival was lower in patients than in the general population through a follow-up period of 38 years. Relative survival was lower in women as compared to men, due to more delayed treatment. Long-term survival was lower after praepyloric perforations than after the other perforation types. Relative survival was higher in patients treated 1952–1970 than in those treated more recently. However, adjustment for year of birth revealed a decline in short-term mortality with calendar time, which is in accordance with improved management during the study period. Relative mortality, particularly long-term mortality, was higher in younger birth cohorts, suggesting a shift towards more serious etiologies.     

Perinatal mortality in relation to birthweight and gestational age: a registry-based comparison of Northern Norway and Murmansk County, Russia

The objective was to explore how perinatal mortality relates to birthweight, gestational age and optimal perinatal survival weight for two Arctic populations employing an existing and a newly established birth registry. A medical birth registry for all births in Murmansk County of North-West Russia became operational on 1st January 2006. Its primary function is to provide useful information for health care officials pertinent to improving perinatal care. The cohort studied consisted of 17,302 births in 2006-07 (Murmansk County) and 16,006 in 2004-06 (Northern Norway). Birthweight probability density functions were analysed, and logistic regression models were employed to calculate gestational-age-specific mortality ratios. The perinatal mortality rate was 10.7/1000 in Murmansk County and 5.7/1000 in Northern Norway. Murmansk County had a higher proportion of preterm deliveries (8.7%) compared to Northern Norway (6.6%). The odds ratio (OR) of risk of mortality (Northern Norway as the reference group) was higher for all gestational ages in Murmansk County, but the largest risk difference occurred among term deliveries (OR 2.45, 95% confidence interval 1.45, 4.14) which hardly changed on adjustment for maternal age, parity and gestation. Proportionately, more babies were born near (± 500 g) the optimal perinatal survival weight in Murmansk County (67.2%) than in Northern Norway (47.6%). The observed perinatal mortality was higher in Murmansk County at all birthweight strata and at gestational ages between weeks 25 and 42, but the adjusted risk difference was most significant for term deliveries.     

Trends in incidence of and mortality from invasive cancer of the uterine cervix in Scotland (1975–1994)

Objective: I. To identify major trends in the incidence of and mortality from invasive cancer of the cervix uteri in Scotland during the twenty year period 1975–1994; II. to consider the extent to which these trends may have been shaped by the introduction of systematic cervical screening.Design: Analysis of annual age standardised and age specific rates for incidence and mortality, based on data collected by the Scottish Cancer Registry and the General Register Office for Scotland.Setting: Scotland.Subjects: Women registered with the Scottish Cancer Registry as having developed invasive cancer of the cervix during the period of interest.Results: Annual all ages incidence rates of invasive cervical cancer show little overall change over the period 1975–1989, but exhibit a pronounced decline from 1990 onwards. All-ages mortality rates show clear evidence of decline during the period 1975–1994, the rate for 1994 being some 30% lower than that for 1975. Annual age-specific incidence rates show different patterns by age group, with clear evidence of decreasing trends in the age range 50–64 years but different patterns in younger and older age groups. Most age groups show steep declines in incidence from 1990 onwards. Age specific mortality rates for 1975–1994 exhibit the most pronounced decreasing trends in the age range 50–64 years. The trends identified are broadly similar to those experienced in England and Wales over an approximately comparable period.Conclusions: The overall (all ages) incidence of invasive cervical cancer in Scotland changed little during the period 1975–1989, but declined sharply from 1990 onwards. The most pronounced decline in incidence across the period 1975–1994 appears to have taken place in the age range 50–64 years. This decline has been accompanied by a commensurate fall in mortality in the same age range. These reductions in incidence and mortality may be attributable in part to increased coverage of cervical screening programmes during the period of interest. Evidence from other studies suggest that, without the increased coverage of cervical screening achieved during this period incidence rates in Scotland might have been seen to increase.     

A health transition: birth weights, households and survival in an Australian working-class population sample born 1857-1900

There is increasing interest in life course epidemiology. In this article we investigated the relationship between characteristics at birth and survival and year of birth and survival. We have detailed information about birth characteristics and cause of death for 8584 subjects from a cohort of 16,272 registered live births to European Australians in a charity hospital in Melbourne between 1857 and 1900. Women giving birth at the hospital were among the poorest in Melbourne, with almost half unmarried. The adult death certificates of the subjects were traced until 1985. We found that infant mortality was substantially higher in babies who were illegitimate, firstborn, had younger mothers, a birth weight <6lb or were a preterm birth. These factors had a weaker association with child mortality and were not associated with adult survival time. Infant mortality was substantially lower in the cohort born 1891-1900 (36%) than previously (58%), a major improvement not seen for child mortality or adult lifespan. Likely reasons for this improvement are the introduction of antisepsis in maternity wards, enforced registration and police supervision of persons other than their mother who cared for babies, strictly monitored feeding practices and a mandatory autopsy and coronial enquiry for such babies who died. We conclude that this is an early example of a successful public health intervention.     

Disappearance of leprosy from Norway: an exploration of critical factors using an epidemiological modelling approach

BACKGROUND: By the middle of the 19th century, leprosy was a serious public health problem in Norway. By 1920, new cases only rarely occurred. This study aims to explain the disappearance of leprosy from Norway. METHODS: Data from the National Leprosy Registry of Norway and population censuses were used. The patient data include year of birth, onset of disease, registration, hospital admission, death, and emigration. The Norwegian data were analysed using epidemiological models of disease transmission and control. RESULTS: The time trend in leprosy new case detection in Norway can be reproduced adequately. The shift in new case detection towards older ages which occurred over time is accounted for by assuming that infected individuals may have a very long incubation period. The decline cannot be explained fully by the Norwegian policy of isolation of patients: an autonomous decrease in transmission, reflecting improvements in for instance living conditions, must also be assumed. The estimated contribution of the isolation policy to the decline in new case detection very much depends on assumptions made on build-up of contagiousness during the incubation period and waning of transmission opportunities due to rapid transmission to close contacts. CONCLUSION: The impact of isolation on interruption of transmission remains uncertain. This uncertainty also applies to contemporary leprosy control that mainly relies on chemotherapy treatment. Further research is needed to establish the impact of leprosy interventions on transmission.     

Risk factors for neonatal mortality in rural areas of Bangladesh served by a large NGO programme

Neonatal deaths account for about half of all deaths among children under 5 years of age in Bangladesh, making prevention a major priority. This paper reports on a study of neonatal deaths in 12 areas of Bangladesh served by a large NGO programme, which had high coverage of reproductive health outreach services and relatively low neonatal mortality in recent years. The study aimed to identify the main factors associated with neonatal mortality in these areas, with a view to developing appropriate strategies for prevention. A case-control design was adopted for collection of data from mothers whose children, born alive in 2003, died within 28 days postpartum (142 cases), or did not (617 controls). Crude and adjusted odds ratios (AOR) were calculated as estimates of relative risk for neonatal death, using 'neighbourhood' controls (241) and 'non-neighbourhood' controls (376). A similar proportion of case and control mothers had received NGO health education and maternal health services. The main risk factors for neonatal death among 122 singleton babies, based on the two sets of controls, were: complications during delivery [AOR, 2.6 (95% CI: 1.5-4.5) and 3.1 (95% CI: 1.8-5.3)], prematurity [AOR, 7.2 (95% CI: 3.6-14.4) and 8.3 (95% CI: 4.2-16.5)], care for a sick neonate from an unlicensed 'traditional healer' [AOR, 2.9 (95% CI 0.9-9.5 and 5.9 (95% CI: 1.3-26.3)], or care not sought at all [AOR, 23.3 (95% CI: 3.9-137.4)]. The strongest predictor of neonatal death was having a previous sibling not vaccinated against measles [AOR, 5.9 (95% CI: 2.2-15.5) and 12.0 (95% CI: 4.5-31.7)]. The findings of this study indicate the need for identification of babies at high risk and early postpartum interventions (40.2% of the deaths occurred within 24 hours of delivery). Relevant strategies include special counselling during pregnancy for mothers with risk characteristics, training birth attendants in resuscitation, immediate postnatal check-up in the home for high-risk babies identified at delivery, advice for mothers on appropriate care-seeking for sick babies, improving the capacity of sub-district hospitals for emergency obstetric and newborn care, and promotion of institutional deliveries.     

Investigating variations in infant mortality in England and Wales by mother's country of birth, 1983-2001

The aim of this study was to investigate variations in infant mortality from 1983 to 2001 by birthweight, registration status, father's social class, age of mother at birth and cause of death, among babies of mothers born in countries that represent the largest ethnic minority groups in England and Wales. A total of 70,208 infant death registration records linked to their corresponding birth registration records were used. The study focused on infant deaths of babies of mothers born in the UK, Republic of Ireland, Caribbean, West Africa, East Africa, India, Pakistan and Bangladesh. From 1983 to 2001 infant mortality rates decreased overall, and this was also apparent in the rates by mother's country of birth. Overall, babies of mothers born in Pakistan consistently had the highest infant mortality rates. Low-birthweight babies of mothers born in West Africa had the highest infant, neonatal and postneonatal death rates. Differences were also seen by registration status, mother's age and between manual and non-manual occupations for all countries from 1983 to 2001. For babies of mothers born in the UK, Caribbean and West Africa, immaturity-related conditions were the most common cause of infant deaths. The leading cause of infant death among babies of mothers born in Pakistan and Bangladesh was congenital anomalies.     

Low birthweight and mortality: the tendency to repeat low birthweight and its association with early neonatal and infant morbidity and mortality

Previous studies have demonstrated the tendency to repeat gestational age and birthweight in successive pregnancies and that this tendency is associated with infant survival. Thus, newborn outcome and survival is less favourable if the gestational age and size departs from this maternal tendency. This paper aims to study diseases or conditions that might be associated with this effect. Data were provided through a linkage between three Danish health registries: the Danish Fertility Database, the National Hospital Registry, and the Registry for Preventive Medicine. Such linkage was possible due to the use of unique ID-person numbers. The study included all 8219 second-order low-birthweight (LBW) singleton Danish births, 1980-94, of whom 7811 were liveborn. It was also required that the mother's first delivery took place during that period. The analysis considered 7803 of these births; eight were excluded due to insufficient information. Of the second-order LBW children, 26% had an elder sibling who was also LBW. Early neonatal mortality of a 'non-repeat' LBW birth was 1.3 times higher than 'repeat' LBW births [53.8 vs. 41.2 per 1000; RR 1.31; 95% CI 1.03, 1.65], as was infant mortality [78.4 vs. 60.8 per 1000; RR 1.30; 95% CI 1.06, 1.56]. Also, proportionately more LBW repeat births had Apgar scores of >or=7 after 1 and 5 min. Overall, repeat second-order LBW babies weighed 68 g more than non-repeat LBW babies (P < 0.001). At term, the weight difference was 160 g higher among repeat LBW births (P < 0.001). The mean number of hospitalisations during the first year of life was lower among repeat than non-repeat LBW babies (2.30 vs. 2.46, P < 0.001), while the mean duration of stay was 23.71 vs. 23.97 days (P > 0.05). Newborn immaturity was the most common diagnosis for hospitalisation, and infections the second most common. There were no differences between repeat and non-repeat LBW births in the proportion with each diagnosis. Apart from the differences in birthweight, we were unable to explain the improved survival for repeat compared with non-repeat LBW babies. Except for differences in Apgar scores, we observed no differences in morbidity based on registered hospitalisations during infancy.     

Implementation research on kangaroo mother care,Bangladesh

ObjectiveTo describe the implementation, coverage and performance of the national kangaroo mother care programme in Bangladesh.MethodsKangaroo mother care services for clinically stable babies with birth weight under 2000 g were set up in government-run health-care facilities in rural and urban areas of Bangladesh. Each facility provided counselling on kangaroo mother care, ensured adequate nutrition, and followed up mothers and babies. We studied implementation of the programme from January 2016 to March 2020 using data from the national database. We tracked the number of eligible babies enrolled and their outcomes, mortality and post-discharge follow-up.FindingsThe numbers of kangaroo mother care facilities increased from 16 in 2016 to 108 in 2020. Over the 4-year period 64 426 babies weighing under 2000 g were born in these facilities,  6410 of whom received kangaroo mother care. The quarterly percentage of eligible babies receiving kangaroo mother care increased from 4.7% (37/792) during the first quarter to 21.7% (917/4226) during the last five quarters of the programme. Deaths of babies receiving kangaroo mother care showed a downward trend over the study period. The overall mortality was 1.2% (77/6410), with large quarterly fluctuations in mortality. Post-discharge follow-up was low and only 15–20% of babies received four follow-up visits.ConclusionImplementation of kangaroo mother care interventions is feasible in low-resource settings. Such care has the potential to reduce mortality among low-birth-weight and premature babies. Challenges include low coverage, expanding the programme to the community and strengthening the monitoring system.     

Primary health care of the newborn baby

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.     

Trends and patterns of mortality associated with birth defects and genetic diseases in the United States, 1979–1992: An analysis of multiple-cause mortality data

Contemporary information on the trends and patterns of mortality associated with birth defects and genetic diseases is lacking in the United States. To study these trends and patterns, we used the Multiple-Cause Mortality Files of the National Center for Health Statistics. From 1979 through 1992,320,208 deaths in the United States were associated with birth defects and genetic diseases. The age-adjusted mortality rates for people with birth defects declined from about 8.2/100,000 in 1979 to about 6.7/100,000 in 1992, and the mortality rates for people with genetic diseases increased from 2.2/100,000 in 1979 to 2.5/100,000 in 1992. The mortality rate was higher among men than among women and higher among blacks than among whites or other races for both birth defect- and genetic disease-associated deaths. The rate among infants with birth defects was more than 25 times higher than that among other age groups. About half of the children whose deaths were associated with birth defects had cardiovascular system defects, 15% had central nervous system defects, and 12% had chromosomal defects. For deaths associated with genetic diseases, hereditary neurologic or storage disorders were the most common genetic diseases (38%), followed by metabolic disorders (21%), sickle cell and thalassemia (12%). The decline in the rate of mortality from birth defects in the United States probably reflects improvements in medical and surgical care and other factors. Most of the mortality associated with birth defects remains in the pediatric age group (less than 15 years old). The upward trend we detected for the deaths with genetic diseases was most likely related to improved recognition and reporting of some genetic diseases rather than to the increased prevalence.

Factors affecting newborn care practices in Bangladesh

Newborn care is of immense importance for the proper development and healthy life of a baby. Although child and infant mortality in South Asia has reduced substantially, the rate of neonatal mortality is still high, although these deaths can be prevented by adopting simple interventions at the community level. The aim of the study was to identify the associated factors which affect newborn care practices. Data for the study were drawn from the Bangladesh Demographic and Health Survey 2007, in which 6150 mothers were considered. The mean age of the mothers was 18 (±3.2) years. A little over 62% of the pregnant women received at least one antenatal check-up during the entire period of their pregnancy. About 70% of deliveries were conducted at home either by unskilled family members or by relatives. A clean instrument was used for cutting the cord of 87% of the newborn babies, while about 34% of them were reported to have had their first bath immediately after delivery. Initiation of breast feeding immediately after birth was practised in only about 19% of the cases. Compared with mothers with no education, those with secondary or higher levels were associated with clean cord care [odds ratio (OR) = 1.3, 95% confidence interval (CI) 1.0, 1.9] and early breast feeding [OR = 1.6, 95% CI 1.2, 2.2]. The study revealed an urgent need to educate mothers, and train traditional birth attendants and health workers on clean delivery practices and early neonatal care. Increasing the number of skilled birth attendants can be an effective strategy to increase safe delivery practices, and to reduce delivery complications.     

Neonatal and postneonatal mortality in Germany since unification

BACKGROUND—After unification, the gap in infant mortality rates between the two parts of Germany widened until 1996 before converging. The reasons for these changes have not, so far, been apparent.
OBJECTIVES—To investigate trends in neonatal and postneonatal mortality in the eastern (the new Länder) and western (the old Länder) part of Germany after unification in 1990 and to identify the scope for further improvement.
DESIGN—Examination of trends in birth weights, birth weight specific neonatal mortality and cause specific postneonatal mortality in the two parts of Germany from 1990 to 1996 and 1997 by analysing routinely available vital statistics data.
RESULTS—In both parts of Germany, neonatal mortality fell considerably, by 33 per cent in the east and 17 per cent in the west, from 4.5 and 3.5 per thousand live births in 1990 to 3.0 and 2.9 in 1997, respectively. This was attributable to an improvement in survival of infants at all birth weights but especially among those with very low birth weights, accounting for an estimated 83 to 85 per cent of the overall improvement. The birth weight distribution showed a slight worsening in the new and the old Länder with an increase in the proportion of those under 1500 g and, in the east, a 24 per cent increase in the proportion of high birthweight infants of 4000 and more grams. Trends in postneonatal mortality revealed a worsening of about 32 per cent in the east from 1990 to 1991 followed by a decline of over 50 per cent up to 1997, leading to comparable mortality rates of 1.8 per thousand live births in the east and 2.0 in the west. While both parts experienced a decrease of 40 to 48 per cent in deaths from all diseases, the decline in deaths because of accidents and injuries was markedly higher in the new Länder although they are still exceeding the western rate by 3.7 per 100 000 live births in 1997.
CONCLUSIONS—Since unification, the two parts of Germany underwent a complex process that has led finally to convergence of parameters of infant health that are most likely to have been because of improvements in the quality of perinatal care. To improve infant mortality in Germany, policy measures should focus on preventive rather than curative measures as the proportion of very low birthweight babies is increasing in both parts of Germany.
