Association of pre-pregnancy BMI and gestational weight gain with fat mass distribution and accretion during pregnancy and early postpartum: a prospective study of Albertan women

What is it about?

Strengths and limitations of this study • The prospective nature of this study allowed for longitudinal measurement and analysis of maternal body fat during pregnancy and early postpartum in relation to the recent IOM gestational weight gain recommendations. • Anthropometric measurements were used to assess fat mass accretion and distribution in this study; trained research staff performed all the data collection to minimize measurement errors. • We used self-reported highest weight to calculate GWG; however, a comparison of this measure to the highest weight measured during prenatal clinic visits showed no significant differences. • Owing to the small sample size of underweight women in this study, most analyses excluded these women.
