Maternal weight gain and birth weight

Abstract Objective The aim of this study is to describe the impact of maternal weight gain on infant birth weight among women with Class III obesity. Study Design Retrospective cohort of women with body mass index (BMI) ≥40 kg/m2 at initial prenatal visit, delivered from July 2013 to December 2017. Women presenting 14/0 weeks of gestational age (GA), delivering preterm, or had multiples or major fetal anomalies excluded. Maternal demographics and complications, intrapartum events, and neonatal outcomes abstracted. Primary outcomes were delivery of large for gestational age or small for gestational age (SGA) infant. Bivariate statistics used to compare women gaining less than Institute of Medicine (IOM) recommendations (LTR) and women gaining within recommendations (11–20 pounds/5–9.1 kg) (at recommended [AR]). Regression models used to estimate odds of primary outcomes. Results Of included women (n = 230), 129 (56%) gained LTR and 101 (44%) gained AR. In sum, 71 (31%) infants were LGA and 2 (0.8%) were SGA. Women gaining LTR had higher median entry BMI (46 vs. 43, p < 0.01); other demographics did not differ. LTR women were equally likely to deliver an LGA infant (29 vs. 34%, p = 0.5) but not more likely to deliver an SGA infant (0.8 vs. 1%, p > 0.99). After controlling for confounders, the AOR of an LGA baby for LTR women was 0.79 (95% CI: 0.4–1.4). Conclusion In this cohort of morbidly obese women, gaining less than IOM recommendations did not impact risk of having an LGA infant, without increasing risk of an SGA infant.

Purpose: The aim of the present study was to examine the influence of a supervised and regular program of aquatic activities throughout gestation on maternal weight gain and birth weight. Design: A randomized clinical trial. Setting: Instituto de Obstetricia, Ginecología y Fertilidad Ghisoni (Buenos Aires, Argentina). Participants: One hundred eleven pregnant women were analyzed (31.6 ± 3.8 years). All women had uncomplicated and singleton pregnancies; 49 were allocated to the exercise group (EG) and 62 to the control group (CG). Intervention: The intervention program consisted of 3 weekly sessions of aerobic and resistance aquatic activities from weeks 10 to 12 until weeks 38 to 39 of gestation. Measures: Maternal weight gain, birth weight, and other maternal and fetal outcomes were obtained by hospital records. Analysis: Student unpaired t test and χ2 test were used; P values ≤.05 indicated statistical significance. Cohen’s d was used to determinate the effect size. Results: There was a higher percentage of women with excessive maternal weight gain in the CG (45.2%; n = 28) than in the EG (24.5%; n = 12; odds ratio = 0.39; 95% confidence interval: 0.17-0.89; P = .02). Birth weight and other pregnancy outcomes showed no differences between groups. Conclusion: Three weekly sessions of water activities throughout pregnancy prevents excessive maternal weight gain and preserves birth weight. Trial Registration: The clinicaltrial.gov identifier: NCT 02602106.
