“…In addition, Hutcheon et al suggest that accurate measurement of weight gain before HDP diagnosis could reduce the impact of weight gain after HDP diagnosis on weight gain during the whole pregnancy (Hutcheon & Bodnar, 2018 ). The appearance of rapid weight gain after 20 weeks reminds us of recessive or neglected oedema during the second half of gestation in our study.…”

Gestational weight management in obese women is critical in clinical work. Adverse pregnancy outcomes are associated with improper gestational weight gain (GWG).However, the pattern of GWG (PGWG) and its correlation with hypertensive disorders of pregnancy (HDP) in obesity are still unclear in China. This retrospective cohort study evaluates clinical data from 799 women through multivariate analyses and trajectory analyses. All the participants are stratified per first trimester weight gain category into three groups (Inadequate-1st, <0.5 kg; Adequate-1st, 0.5-2.0 kg; Excessive-1st, >2.0 kg) and PGWG refers to the weekly weight gain during each gestational period. GWG is positively associated with first trimester weight gain. 78.4% of the Excessive-1st participants have excessive total GWG, in contrast toInadequate-1st (32.7%) and Adequate-1st (48.2%). After 20 weeks, the weekly weight gain rapidly accelerates, and 77.3% have a weekly weight gain exceeding the Institute of Medicine recommendations. Trajectory analysis of weekly weight gain based on HDP shows two separate weight gain curves after 20 weeks in women with and without a high risk of HDP. Especially in Excessive-1st participants, weekly weight gain after 20 weeks over 0.32 kg/w is positively related to the risk of HDP (<0.32 kg/w vs.

“…However, the potential bias in the timing of data collection for delivery weight has been noted by others. 19,20 Importantly, additional bias may exist owing to systematic differences in the interval between the last weight collected and delivery between groups. For example, differences in timing of the last measured weight and delivery have been noted among women with term and preterm deliveries and among women with stillbirths.…”

Minimization of bias in measures of gestational weight gain

Summary Gestational weight gain (GWG) is an important predictor of adverse pregnancy outcomes including gestational diabetes, preterm birth, delivery by caesarean and post‐partum weight retention. The Institute of Medicine guidelines on GWG are widely adopted, and GWG is widely researched as an outcome of interest in lifestyle interventions during pregnancy. However, estimation of prepregnancy weight and measurement of weight prior to delivery introduce bias into measures of GWG. This review discusses the sources of bias in measures of GWG and the potential effect of bias on the relationship between adverse pregnancy outcomes associated with GWG. Bias in measures of GWG can be minimized by using measured weight at the first antenatal appointment in early pregnancy rather than self‐reported prepregnancy weight and by adjusting for gestational age when the last weight is collected earlier than the delivery date. Bias owing to gestational age is an important potential confounder in the relationship between GWG and adverse pregnancy outcomes.
