Weight gain patterns among pregnancies with obesity and small- and large-for-gestational-age births.

ABSTRACT:

Objective

This case-cohort study estimated associations between gestational weight gain (GWG) and small-for-gestational-age (SGA) and large-for-gestational-age (LGA) births stratified by obesity class (I: 30-34.9 kg/m² ; II: 35-39.9 kg/m² ; III: ≥40 kg/m² ) (Magee-Womens Hospital, Pittsburgh, Pennsylvania, 1998-2011).

Methods

First-trimester GWG was categorized as being below (<0.2 kg), within (0.2-2.0 kg), or above (>2.0 kg) the Institute of Medicine recommendations. For second- and third-trimester GWG, four linear trajectories were derived: approximating maintenance (slope -0.05 ± 0.03 kg/wk), approximating the recommendations (0.27 ± 0.01 kg/wk; reference), higher than the recommendations (0.54 ± 0.01 kg/wk), and highest among those above
