OBJECTIVE: The Institute of Medicine (IOM) 2009 gestational weight gain (GWG) guidelines are based on prepregnancy body mass index (BMI) categories. We intended to refine optimal GWG for each prepregnancy BMI unit in relation to the risk of small- and large-for-gestational-age (SGA and LGA) births, cesarean section (C-section) and infant death. STUDY DESIGN: We used data from 836,841 Ohio birth records from 2006 to 2012, and applied generalized additive models to calculate optimal GWG by prepregnancy BMI unit...

BACKGROUND: Excessive gestational weight gain is associated with short and long-term adverse maternal and infant health outcomes, independent of pre-pregnancy body mass index. Weighing pregnant women as a stand-alone intervention during antenatal visits is suggested to reduce pregnancy weight gain. In the absence of effective interventions to reduce excessive gestational gain within the real world setting, this study aims to test if routine weighing as a stand-alone intervention can reduce total pregnancy weight gain and, in particular, excessive gestational weight gain...

BACKGROUND: During pregnancy, maternal circulating leptin is released by maternal adipose tissue and the placenta, and may have a role in fetal development. OBJECTIVES: We investigated maternal leptinemia and glycemia associations with neonatal adiposity, taking into account pregravid weight status. METHODS: We included 235 pregnant women from the Genetics of Glucose Regulation in Gestation and Growth prospective cohort with data: blood samples collected during the 2nd trimester, an oral glucose tolerance test (OGTT), and the measured leptin and glucose levels...

BACKGROUND: Pregnancy weight gain is believed to contribute to female overweight and obesity. However, most studies do not account for the changes in body weight expected to occur as women age. We examined the long-term weight trajectory of childbearing women relative to weight progression that could be expected in the absence of pregnancy. METHODS: From the hospital records of 32,187 women with two births in Wisconsin during 2006 to 2013, we extracted the maternal weight at pregravid, delivery, and subsequent pregravid...

Lower neighbourhood-level socioeconomic status (SES) has been repeatedly associated with an increased risk of adverse birth outcomes, even after controlling for individual-level SES. Few studies have empirically assessed potential mechanisms underlying the associations. The objectives of this study were to (1) examine relations between neighbourhood SES and birth outcomes, and (2) explore if maternal weight variables mediated these relations. Data came from a provincial prospective pregnancy cohort study in Canada...

We investigated arsenite exposure on the reproductive axis of dams (during pregnancy and at cyclicity resumption) and their offspring. Pregnant rats were exposed to 5 (A5) or 50ppm (A50) of sodium arsenite in drinking water from gestational day 1 (GD1) until sacrifice at GD18 or two months postpartum. Offspring were exposed to the same treatment as their mothers from weaning to adulthood. A50-pregnant rats gained less weight, showed increased testosterone and estradiol but pregnancy was unaffected. After lactation, arsenic-exposed dams presented compromised cyclicity, decreased estradiol, increased follicle-stimulating hormone (FSH), less preovulatory follicles and presence of ovarian cysts, suggesting impaired reproduction...

BACKGROUND: Gestational weight gain is often characterized by the total amount of weight gained during pregnancy, however, the pattern of gain may be an important determinant of health outcomes. The SITAR (Super Imposition by Translation And Rotation) model has been used to describe childhood growth trajectories and has appeal because of the biological interpretability of its parameters. The objective of this study was to determine the feasibility of applying this model to gestational weight gain trajectories...

Data from 807 mothers in Iran delivering a singleton live infant and their offspring during the last two years up to August 2014 were collected from eight public health care centers and analyzed. Of women, 46.2% gained weight within the recommended range, 29.4% had inadequate and 24.4% had excessive gestational weight gain (GWG). Excessive GWG was more common among overweight and obese women, whereas inadequate GWG were prevalent among 50% of under and normal weight women. After adjusting for appropriate confounding factors the significant correlation was found between maternal anthropometric characteristics, folic acid intake during pregnancy and birth order with GWG...

The goals of the present targeted review on maternal and child overweight and obesity were to: (i) understand the current situation in low- and middle-income countries (LMIC) with regard to recent trends and context-specific risk factors; and (ii) building off this, identify entry points for leveraging existing undernutrition programmes to address overweight and obesity in LMIC. Trends reveal that overweight and obesity are a growing problem among women and children in LMIC; as in Ghana, Kenya, Niger, Sierra Leone, Tanzania and Zimbabwe, where the prevalence among urban women is approaching 50 %...

PURPOSE: Body size, from birth throughout adulthood, is associated with breast cancer risk, but few studies have investigated early-life body size and benign breast disease (BBD), a well-established breast cancer risk factor. We consider whether prenatal factors and size at birth, 10, 18 year, and intervening growth, are related to BBD risk. METHODS: The Growing Up Today Study includes 9032 females who completed questionnaires annually from 1996 to 2001, then 2003, 2005, 2007, 2010, and 2013...

BACKGROUND: In the United States, a high percentage of pregnant women gain weight outside of the current Institute of Medicine's (IOM) gestational weight gain (GWG) recommendations. There is limited research examining the relationship between GWG and onset of lactation. Delayed onset of lactation (DOL) can negatively affect breastfeeding outcomes. METHODS: Secondary data analysis was conducted using data from 2,053 women who participated in the population-based Infant Feeding Practices Study II between 2005 and 2007...
