OBJECTIVE: We assessed whether umbilical cord blood placental growth factor (PlGF) levels at delivery are associated with fetal growth. METHODS: From a prospective population-based cohort study we included 3,461 live singleton births. Fetal growth was assessed by birth weight, fetal growth pattern, and fetal growth restriction (FGR; decrease in growth between the second trimester and birth of ≥40 percentiles). In all analyses the highest PlGF multiple of the median (MoM) quintile was used as the reference category...

BACKGROUND: Congenital diaphragmatic hernia (CDH) is a relatively frequent and severe malformation. Population-based data on clinical presentation and associated mortality are scarce. We examined a state-wide cohort of infants with a clinically validated diagnosis of CDH to assess their clinical profile, sociodemographic patterns, and infant mortality. METHODS: We identified CDH cases from Utah's statewide population-based surveillance program among the cohort of all pregnancy outcomes (live births, stillbirths, and pregnancy terminations) delivered from 1999 to 2011...

BACKGROUND: There is growing interest in exposures prior to conception as possible risk factors for offspring asthma. Although partially supported by evidence from limited human studies, current evidence is inconsistent, and based on recall of exposure status. OBJECTIVE: We aimed to investigate grandmaternal smoking during pregnancy and the risk of asthma in grandchildren using prospectively collected population-based data. METHODS: Information on grandmaternal and maternal smoking during pregnancy and grandchild use of asthma medications was collected from national Swedish registries...

BACKGROUND/OBJECTIVES: Growing evidence suggests that antibiotic use is associated with childhood body mass index (BMI), potentially via mechanisms mediated by gut microbiome alterations. Less is known on the potential role of prenatal antimicrobial use in offspring obesity risk. We examined whether prenatal antibiotic or antifungal use was associated with BMI at the age of 2 years in 527 birth cohort participants. METHODS/SUBJECTS: Antimicrobial use was obtained from the prenatal medical record...

INTRODUCTION: The risk of stillbirth associated with maternal obesity increases with gestational age, however it is unclear if earlier delivery reduces the overall perinatal mortality rate. Our objective was to compare the risk of perinatal mortality associated with each additional week of expectant management to that of immediate delivery. METHODS: This was a retrospective cohort study of singleton nonanomalous births in Texas between 2006 and 2011. Analyses were stratified based on maternal prepregnancy BMI class...

With the national push to expand preschool education, there has been growing interest in understanding why Latino families are enrolled in preschool at lower rates than non-Latino families. This study applied the accommodations model by Meyers and Jordan (2006) to the Early Childhood Longitudinal Study-Birth Cohort (n = 5,850) to provide a more nuanced understanding of the preschool selection of U.S.- and foreign-born Latino families. Results from this investigation underscored the similarities and differences that existed in the selection behaviors of different groups of families, while also highlighting important differences within the Latino population...

OBJECTIVE: There is evidence to suggest that individual components of dietary intake are associated with depressive symptoms. Studying the whole diet, through dietary patterns, has become popular as a way of overcoming intercorrelations between individual dietary components; however, there are conflicting results regarding associations between dietary patterns and depressive symptoms. We examined the associations between dietary patterns extracted using principal component analysis and depressive symptoms, taking account of potential temporal relationships...

This study assessed the incidence and risk factors for dengue virus (DENV) infection among children in a prospective birth cohort conducted in the city of Recife, a hyperendemic dengue area in Northeast Brazil. Healthy pregnant women (n = 415) residing in Recife who agreed to have their children followed were enrolled. Children were followed during their first 24 months of age (May/2011-June/2014), before the 2015 Zika virus outbreak. DENV infection was detected by reverse-transcriptase polymerase chain reaction and/or serology (anti-DENV IgM/IgG)...

BACKGROUND: Prenatal perfluorooctanoate (PFOA) exposure has been associated with reduced birth weight but maternal glomerular filtration rate (GFR) may attenuate this association. Further, this association remains unclear for other perfluoroalkyl substances (PFAS), such as perfluorooctane sulfonate (PFOS), perfluorohexane sulfonate (PFHxS), and perfluorononanoate (PFNA). We estimated associations between prenatal PFAS exposure and birth outcomes, and the influence of GFR, in a Spanish birth cohort...
