BACKGROUND Maternal folate depletion has been proposed as a primary explanation for the excess risk of fetal growth restriction associated with short interpregnancy intervals. OBJECTIVE We aimed to evaluate the folate depletion hypothesis in a community-based cohort of pregnant women. DESIGN Using a subsample of the cohort (multiparous participants who delivered a liveborn singleton infant,...

We aim to identify the link between placental histological findings and obstetric reports to determine possible risk factors of spontaneous preterm birth (SPTB). We prospectively ascertained birth records and outcomes from all deliveries in our hospital in 1 year. Records were used to determine and stratify for either full-term or preterm [spontaneous or indicated (I)] deliveries. We analyzed f...

BACKGROUND Elective cervical cerclage has been purported to prevent spontaneous preterm birth. We present a systematic review to determine the effectiveness of cervical cerclage in preventing spontaneous preterm birth before 34 weeks' gestation. METHODS Searches were conducted in MEDLINE, EMBASE, Cochrane Library, and Science Citation Index to identify randomized trials published between 1966...

The aim of this retrospective study was to characterise intrapartum and neonatal outcomes in women with an antenatally recorded Edinburgh Postnatal Depression Score (EPDS) ≤ 9 compared with women with a score of ≥12 at a major Australian tertiary maternity hospital. Women with scores ≥12 are at particularly high risk of major depressive symptomatology. There were 20512 (78.6%) women with a scor...

Objectives  Despite the morbidity associated with late preterm and early-term births, there is limited data on pregnant women's perception of neonatal risk based on gestational age (GA). Therefore, our objective was to determine pregnant women's perception of neonatal risks at varying GAs. Method  Through an anonymous 24-question survey, pregnant women were asked to designate the GA at delivery...

OBJECTIVES Assuming that the occurrence of preterm births and their maternal and neonatal associated conditions in Brazil are not completely known, a multicenter study was proposed. The purpose of this paper is to describe the methods used, its processes, achievements, and challenges. STUDY DESIGN A multicenter cross-sectional study on preterm births in Brazilian facilities plus a nested case...

Most research on outcomes of preterm birth has centered on babies born at <32 weeks gestation and at highest risk of mortality and serious morbidity. Recent years have seen a dramatic increase in studies focusing on late preterm infants (34-36 weeks gestation). Early epidemiological studies demonstrated increased risks of mortality and adverse neonatal outcomes in this group, prompting further ...

BACKGROUND Studies of unconventional gas development (UGD) and preterm birth (PTB) have not presented risk estimates by well development phase or trimester. OBJECTIVE We examined phase and trimester-specific associations between UGD activity and PTB. METHODS We conducted a case-control study of women with singleton births in the Barnett Shale area, Texas, from 30 November 2010 to 29 Novembe...

The effects of prenatal exposure to pollutants from the World Trade Center (WTC) disaster on fetal growth and subsequent health and development of exposed children remain a source of concern. We assessed the impact of gestational timing of the disaster and distance from the WTC in the 4 weeks after 11 September on the birth outcomes of 300 nonsmoking women who were pregnant at the time of the e...

BACKGROUND Violence by intimate partner during pregnancy has many adverse pregnancy outcomes. Thus, that's why we sought to determine association between intimate partner violence during pregnancy and adverse birth outcomes. METHODS A facility based cross-sectional study was conducted among 183 recently delivered women from March 31-April 30, 2014 in public health facilities of Hossana Town. ...
