Patterns of gestational weight gain among women with obesity and its correlation with hypertensive disorders of pregnancy in Chinese women

Abstract

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.

Associations of gestational weight gain with birth weight outcomes in early pregnancy weight loss women: Findings from the Beijing Birth Cohort Study

“…This new Chinese standard of recommendation has been proven more suitable for Chinese people than the US National Academy of Medicine guidelines 23 . In addition, this phenomenon of catch up weight gain in mid‐late pregnancy corroborates with the previous study in our group, which showed that obese women with inadequate weight gain in the first trimester had paradoxically more rapid weekly weigh gain after 20 weeks 24 . According to our optimal weight gain rates, women who had higher weight gain rate increased risk of macrosomia and LGA, which suggested that the early pregnancy weight loss women also need to be aware of excessive weight gain.…”

Due to the low incidences of SGA and full-term LBW in our study, we did not find a relationship between lower weight gain rate and the risk of SGA and full-term LBW.…”

Gestational weight gain velocity during each trimester is critical for both maternal health and birth outcomes in China

“…The purpose of this special collection of papers is to bring together research that has been conducted on GWG in China. These papers (Song et al, 2023 ; Wang et al, 2023 ; Yang et al, 2023 ) provide new local evidence that may be used for developing global GWG guidelines.…”

“…The second paper in this section describes the relationship between GWG timing (each trimester) and hypertensive disorders during pregnancy (i.e. gestational hypertension and pre‐eclampsia) in obese women (Song et al, 2023 ). In their retrospective cohort study, Song et al ( 2023 ).…”

“…gestational hypertension and pre‐eclampsia) in obese women (Song et al, 2023 ). In their retrospective cohort study, Song et al ( 2023 ). reported that excessive weight gain during the first trimester and rapid weekly weight gain after 20 weeks predicted a high risk of hypertensive disorders in obese pregnant women.…”
