OBJECTIVE: To study the relation between birthweight of term infants and maternal occupation. METHODS: Information on job titles since the age of 16, and sociodemographic and other lifestyle factors were obtained by means of questionnaires as part of the Avon longitudinal study of pregnancy and childhood (ALSPAC), from a cohort ...

Comparisons of infant, perinatal, or neonatal mortality across populations with different birthweight or gestational age distributions are problematic. Summary measures with adjustment for birthweight or gestational age frequently are invalid or lack interpretability. We propose a percentile-based method of standardization for comparing infant, perinatal, or neonatal mortality across populations that ...

Factors in the U.S. healthcare system have shifted the site of care of many newborns to hospitals where subspecialty services are unavailable. This study examines whether a more rapid turn-around of echocardiogram interpretations and availability of interactive video during neonatal consultations reduces the morbidity of very low birthweight (VLBW) infants. ...

The mean birthweight has decreased recently in Japan. The author assessed the etiology of this trend by comparing the birthweight during the years 1983-1984 and 1993-1994 in Central Japan. All birth certificates of 3767 and 3423 infants were available for 1983-1984 and 1993-1994, respectively. The mean birthweight decreased from 3165 ...

Very low birthweight (VLBW) infants undergoing neonatal intensive care are at risk of infection with coagulase-negative staphylococci (CONS). This study investigates the efficacy of twice daily, 1 h infusions of vancomycin (5 mg kg) in reducing CONS infection in VLBW infants receiving parenteral nutrition. Of 72 infants in the study, ...

A retrospective study was performed at a tertiary maternity hospital, to define the incidence of low birthweight (LBW) and its associated risk factors in term liveborn infants and in term stillbirths, to ascertain the antenatal detection rate in each and to assess the role of ultrasound in antenatal detection. One ...
Andersson R - - 1997
The birthweight is the most important determinant of mortality and morbidity in the neonatal period and may have an influence on health in adult life. The high rate of low birthweight in developing countries is therefore a major health problem. Maternal malnutrition is usually assumed to be a causal factor ...

The recently introduced intrauterine growth curve, based on ultrasonically estimated foetal weights, was retrospectively applied to an inborn population of 883 infants born before 33 gestational weeks at the University Hospital of Lund, during 1985-94. The estimation of birthweight deviation resulted in 630 (71.3%) infants with a birthweight appropriate for ...
Coory M - - 1997
Between-area comparisons of neonatal mortality rates should be adjusted for differences in the underlying mortality risk. The traditional approach to this problem is to adjust neonatal mortality rates statistically for between-area differences in the birthweight distributions. However, in other types of perinatal research, birthweight is usually considered in combination with ...
Klufio C A - - 1997
A retrospective study of 432 consecutive singleton low birthweight babies and 432 unmatched controls was carried out at the Port Moresby General Hospital from January to December 1988. Of the 432 low birthweight babies 65% were preterm, 27% were light for gestational age, 6% were both preterm and light for ...

An extremely low birthweight (ELBW) protocol was developed at this regional neonatal intensive care unit. The focus was the standardization of care related to the implementation/maintenance of a humidified environment and attention to prevention of skin excoriation in the extremely low birthweight infant (< 1000 g). Steps toward successful implementation ...
Gaudino J A JA - - 1997
OBJECTIVES: Although more fetal deaths than neonatal deaths occur, routinely collected fetal death data are seldom used for perinatal epidemiologic research because of data quality concerns. We developed a strategy for identifying and correcting errors in birthweight and gestational age in fetal death records. METHODS: Using data from Georgia for ...
Svenningsen N W - - 1997
Perinatal care of the extremely preterm and low birthweight (ELBW) infant is founded on basic principles of physiology and knowledge about the prevailing pathophysiological mechanisms. New therapies in clinical care are usually introduced non-uniformly, so more often there is a gradual rather than a sudden change in the development of ...

OBJECTIVES: This study examined whether the decline in birth-weight with increasing altitude is due to an independent effect of altitude or an exacerbation of other risk factors. METHODS: Maternal, paternal, and infant characteristics were obtained from 3836 Colorado birth certificates from 1989 through 1991. Average altitude of residence for each ...
Walraven G E - - 1997
In a hospital-based study, birthweights of 3162 consecutive births were related to perinatal mortality, multiple birth, and gestational age. Independent associations between 15 potential determinants and low birthweight, prematurity and small-at-term factors were also assessed. A newly constructed local curve of birthweight-for-gestational age is compared with the existing curves. The ...

This paper reports two mechanically ventilated preterm babies who received overdoses of pethidine in the neonatal period. One of the neonates (gestational age 26 weeks, birthweight 1040 g) received repeated appropriate doses, which resulted in central nervous system irritability and convulsion due to accumulation of the drug and its metabolite, ...

Kim B I - - 1996
Neonatal intensive care has increased neonatal survival, but has also led to postponement of some of the neonatal deaths to the postneonatal period, particularly in very low birthweight (< 1.5 kg) infants. Our report assesses the impact of the increased neonatal survival and the accompanying delayed deaths on the crude ...
Peabody J L - - 1996
In recent years, survival of the extremely low birthweight infant has dramatically improved. Morbidity, both short- and long-term, however, remains very high Costs in the currency of pain and suffering for the newborn, stress and financial burdens for the family, and dollars for society are extensive. The controversial questions that ...
