STUDY OBJECTIVE The aim was to investigate whether specific types of work or exposures among pharmacy assistants were correlated with changes in birth weight or gestational age. DESIGN The study was a nationwide historical cohort with open entry of all female members of the union of pharmacy assistants during 1979 to 1984. PARTICIPANTS The cohort comprised 4939 pharmacy assistants under 40 ...

Abstract Background and purpose:Women’s health, as almost “half of the population of each society” and in recent years as “half of the workforce,” is of particular importance in achieving sustainable development goals. The aim of this study is to investigate the relationship between birth weight and gestational age and mother’s employment. Materials and Metho...

BACKGROUND Preterm birth is the leading cause of death among children <5 years of age. Accurate determination of prematurity is necessary to provide appropriate neonatal care and guide preventive measures. To estimate the most accurate method to identify infants at risk for adverse outcomes, we assessed the validity of two widely available methods-last menstrual period (LMP) and the New Ballard...

Approaches for analyzing the risks of adverse pregnancy outcomes have been the source of much debate and many publications. Much of the problem, in our view, is the conflation of time at risk with gestational age at birth (or birth weight, a proxy for gestational age). We consider the causal questions underlying such analyses with the help of a generic directed acyclic graph. We discuss competi...

background and objectives: the diagnosis of pregnancy associated adnexal masses is rising due to routine utilization of sonography in prenatal care. the purpose of this study was to describe pregnancy associated adnexal masses over a period of 10 years. patients and methods: a retrospective study was reviewed hospital records of all pregnant women with adnexal mass that underwent surgical resec...

BACKGROUND The effects of in utero exposure to atypical antipsychotics on infant birth weight are unknown. AIMS To determine whether atypical and typical antipsychotics differ in their effects on birth weight after maternal exposure during pregnancy. METHOD Prospective data on gestational age and birth weight collected by the National Teratology Information Service for infants exposed to ty...

conclusion the incidence of rop is relatively high in this region. risk factors for rop among very premature infants include hypoxia, severe hyperoxia, relatively low blood spo2, gestational age, birth weight, and apgar score. results the incidence of rop was 26.2%. significant differences between the rop and control groups were observed, these include; gestational age, sex, birth weight, apgar...

BACKGROUND Stress is an inevitable part of life, and maternal stress during the gestational period has dramatic effects in the early programming of the physiology and behavior of offspring. The developmental period is crucial for the well-being of the offspring. Prenatal stress influences the developmental outcomes of the fetus, in part because the developing brain is particularly vulnerable to...

OBJECTIVE To develop a reference of population-based gestational age-specific birth weight percentiles for contemporary Chinese. METHODS Birth weight data was collected by the China National Population-based Birth Defects Surveillance System. A total of 1,105,214 live singleton births aged ≥28 weeks of gestation without birth defects during 2006-2010 were included. The lambda-mu-sigma method ...

The primary aim of this study was to investigate whether women born prematurely or with impaired fetal growth have a reduced probability of giving birth. Using Swedish population-based registries, the authors identified 148,281 women born in 1973-1975 for follow-up until 2001. Of these women, 4.1% were born preterm and 0.32% very preterm, 0.29% were born with a very low birth weight, and 5.4% w...
