BACKGROUND: Maternal obesity is increasingly prevalent in many westernized countries. Many studies report associations between maternal obesity and childhood wheeze or asthma but few have considered maternal obesity in relation to respiratory infections or symptoms other than wheeze during infancy. This study assesses the relationship between maternal BMI and reported wheeze, cough and respiratory infections during the first year of life. METHODS: In 2799 mother-child pairs, we examined the relations between maternal pre-pregnancy BMI and pregnancy weight gain and reported offspring wheeze, prolonged cough, lower respiratory tract infection, croup, and ear infection before age 1 year, along with reported diarrhea or vomiting...

INTRODUCTION: Gestational weight gain (GWG) varies widely among different populations, and an inappropriate GWG is associated with adverse pregnancy outcomes. We aimed to investigate week-specific serial changes in GWG in an urban Chinese population to derive clusters of GWG pattern and explore the impact of GWG patterns on birthweight. MATERIAL AND METHODS: This was an observational cohort study of 6130 women delivered at a university hospital in Shanghai, China...

BACKGROUND: Excess adiposity in childhood is associated with numerous adverse health outcomes. As this condition is difficult to treat once present, identification of risk early in life can help inform and implement strategies to prevent the onset of the condition. We performed an epigenome-wide association study to prospectively investigate the relationship between cord blood DNA methylation and adiposity measurements in childhood. METHODS: We measured genome-wide DNA methylation from 478 children in cord blood and measured overall and central adiposity via skinfold caliper measurements in early (range 3...

INTRODUCTION: Maternal obesity, high gestational weight gain and diabetes mellitus during pregnancy are known risk factors that correlate with high infant birth weight and the mother's race. Previous studies have focused on low birth weight, prematurity and infant mortality. This study examined the interaction between race, maternal risk factors and high infant birth weights at the population level in South Dakota to identify factors contributing to the high Native American infant birth weights...

BACKGROUND: An understanding of the dietary behaviors linked to substantial postpartum weight retention, particularly in women diagnosed with gestational diabetes (GDM), is warranted to focus intervention efforts to prevent future type 2 diabetes. This study evaluates the relationship between dietary food intake at 6-9 weeks postpartum (baseline) and odds of substantial postpartum weight retention (≥ 5 kg) at 1-year in women with GDM. METHODS: The Study of Women, Infant Feeding and Type 2 Diabetes after GDM pregnancy (SWIFT) is a prospective multi-ethnic cohort (75% minority) of 1035 women (aged 20-45 years) with recent GDM who delivered a singleton, live birth (≥35 weeks gestation) and underwent 2-h 75 g OGTTs, anthropometric measurements and other assessments at 6-9 weeks postpartum (baseline) and annually thereafter...

AIMS: There is no previous study comparing the predictive ability of maternal pre-pregnancy body mass index (BMI) versus a 75-g oral glucose tolerance test (OGTT) in early pregnancy for large-for-gestational-age (LGA) infants. METHODS: This multi-institutional prospective cohort study included 966 pregnant Japanese women. A multiple logistic regression model was applied to compare the effect size of pre-pregnancy BMI, fasting plasma glucose (PG), and 1- and 2-h PG levels after a 75-g OGTT performed before 22weeks gestation for LGA...

AIMS: Epigenetic regulators, including microRNAs (miRNAs), are implicated in type 2 diabetes, but evidence linking circulating miRNAs in pregnancy and risk of gestational diabetes (GDM) is sparse. Potential modifiers, including pre-pregnancy overweight/obesity and offspring sex, are unexamined. We hypothesized that circulating levels of early-mid-pregnancy (range 7-23weeks of gestation) candidate miRNAs are related to subsequent development of GDM. We also hypothesized that miRNA-GDM associations might vary by pre-pregnancy body-mass index (ppBMI) or offspring sex...

Human placenta is a fetal-derived tissue that offers a unique sample of epigenetic and environmental exposures present in utero. In the MARBLES prospective pregnancy study of high-risk younger siblings of children with autism spectrum disorder (ASD), pregnancy and environmental factors collected by maternal interviews were examined as predictors of placental DNA methylation, including partially methylated domains (PMDs), an embryonic feature of the placental methylome. DNA methylation data from MethylC-seq analysis of 47 placentas of children clinically diagnosed at 3 years with ASD or typical development using standardized assessments were examined in relation to: child's gestational age, birth-weight, and diagnosis; maternal pre-pregnancy body mass index, smoking, education, parity, height, prenatal vitamin and folate intake; home ownership; pesticides professionally applied to lawns or gardens or inside homes, pet flea/tick pouches, collars, or soaps/shampoos used in the 3 months prior to or during pregnancy...

Introduction It has been established that underweight women with low gestational weight gain (GWG) are at a higher risk of having Small for Gestational Age (SGA) newborns. However, the association remains poorly studied in Middle Eastern societies exhibiting different ethnic groups, genetic predisposing factors along with differences in nutritional food intake during pregnancy. The aim of this study is to assess the risk of having a SGA newborn among underweight and normal weight BMI women while studying the role of GWG in this association...

BACKGROUND: Bleeding disorders are uncommon but may pose significant bleeding complications during pregnancy, labour and following delivery for both the woman and the foetus. While many bleeding disorders in women tend to improve in pregnancy, thus decreasing the haemorrhagic risk to the mother at the time of delivery, some do not correct or return quite quickly to their pre-pregnancy levels in the postpartum period. Therefore, specific measures to prevent maternal bleeding and foetal complications during childbirth, are required...

OBJECTIVE: Pregnancy serves as an opportune time for "teachable moments" to elicit positive behavior change. We evaluated change in exercise perception, behavior and gestational weight gain in participants engaged in a one-hour educational experience. METHODS: Women between 28 0/7 to 36 6/7 weeks with no prior yoga experience carrying a non-anomalous singleton fetus participated in a randomized controlled trial on prenatal yoga. The yoga group engaged in a one-hour yoga class; the attention control educational group, in a one-hour presentation on exercise, nutrition and obesity in pregnancy...

BACKGROUND: Evolving animal studies and limited epidemiological data show that prenatal air pollution exposure is associated with childhood obesity. Timing of exposure and child sex may play an important role in these associations. We applied an innovative method to examine sex-specific sensitive prenatal windows of exposure to PM2.5 on anthropometric measures in preschool-aged children. METHODS: Analyses included 239 children born ≥ 37 weeks gestation in an ethnically-mixed lower-income urban birth cohort...

OBJECTIVE: Many studies have identified early-life risk factors for subsequent childhood overweight/obesity, but few have evaluated how they combine to influence risk of childhood overweight/obesity. We examined associations, individually and in combination, of potentially modifiable risk factors in the first 1000 days after conception with childhood adiposity and risk of overweight/obesity in an Asian cohort. METHODS: Six risk factors were examined: maternal pre-pregnancy overweight/obesity (body mass index (BMI) ⩾25 kg/m(2)), paternal overweight/obesity at 24 months post-delivery, maternal excessive gestational weight gain, raised maternal fasting glucose during pregnancy (⩾5...

INTRODUCTION: Sickle cell disease in pregnancy carries a high risk of maternal and fetal adverse outcomes. The use of prophylactic transfusions to reduce the risk of sickle complications is controversial. Current UK standards do not recommend the routine use of transfusion for sickle pregnancy. We examined transfusion episodes during sickle pregnancies in a single centre over an 11-year period. METHODS: We conducted a retrospective observational study of all pregnancies in patients with sickle cell disease who attended the joint obstetric/haematology clinic over an 11-year period...
