Adolescent girls and their babies: achieving optimal birthweight. Gestational weight gain and pregnancy outcome in terms of gestation at delivery and infant birth weight: a comparison between adolescents under 16 and adult women1

Purpose: We aimed to describe adherence to gestational weight gain (GWG) recommendations and identify determinants of excessive GWG in a sample of women from Quebec, Canada. Methods: Data were collected from the multi-centre 3D (Design, Develop, Discover) pregnancy cohort study, which included women who delivered between May 2010 and August 2012 at 9 obstetrical hospitals in Quebec, Canada. GWG was calculated for 1145 women and compared to the 2009 Institute of Medicine (IOM) recommendations. Results: Overall, 51% of participants exceeded the recommendations. Approximately 68% of women with obesity gained weight in excess of the IOM recommendations. The corresponding numbers were 75%, 44%, and 27% in overweight, normal weight, and underweight women, respectively. A prepregnancy BMI of 25 kg/m2 or more was the only significant predictor of exceeding GWG recommendations (OR 3.35, 95% CI 2.44–4.64) in a multivariate model. Birth weight was positively associated with GWG. GWG and prepregnancy BMI could explain 3.13% and 2.46% of the variance in birth weight, respectively. Conclusion: About half of women exceeded GWG recommendations, and this was correlated with infant birth weight. This reinforces the need to develop and evaluate strategies, including nutritional interventions, for pregnant women to achieve optimal GWG.

Background: Gestational weight gain (GWG) and pre-pregnancy body mass index (BMI) play important roles in determining the pregnancy outcome. The weight gain recommendations by the IOM are based on Western WHO BMI cut-offs, making it difficult to generalize their findings to Asian Indians. We aimed to compare GWG among healthy pregnant women across different BMI with the IOM guidelines-2009. We also aimed to evaluate associated feto-maternal outcomes with GWG among the pregnant women enrolled in the study.Methods: A retrospective cohort study conducted at department of obstetrics and gynecology, from April 2019 to November 2019. Postnatal mothers whose weight was registered at first trimester of pregnancy and at term and delivered in SSG hospital were included. According to IOM Women were divided into: Group 1 less than recommended weight gain and Group 2 recommended weight gain.Results: Significant difference was seen in the baby weight between the two groups (p value <0.05). 92.75% of babies had low birth weight in Group 1 as compared to 42.21% in Group 2. On performing univariate logistic regression, significant association was seen between GWG and low birth weight (p <0.05), no association was seen between GWG and caesarean (p value >0.05), and no association was seen between GWG and preterm deliveries (p >0.05).Conclusions: Majority of patients in the both groups had term delivery. Women gaining less than recommended weight gain during pregnancy had new born with significantly lower birth weight. There was no association of mode of deliveries and GWG.
