Retrospective cohort study reveals links between gestational weight gain and pregnancy outcomes in women, suggesting implications for care.
Key Points
The central aim was to investigate the relationship between gestational weight gain at 24 weeks and pregnancy outcomes based on the 2022 Chinese guideline.
Conducted a single-center retrospective cohort study of singleton live births at Shanghai General Hospital in 2021.
Calculated gestational weight gain at 24 weeks (GWG24) based on measured weight and self-reported pre-pregnancy weight.
Utilized logistic regression analyses to evaluate associations between GWG24 and various pregnancy outcomes.
Below-range GWG24 was associated with higher odds of small for gestational age (SGA) with an adjusted OR of 3.00 (95% CI 1.46–6.14).
Below-range GWG24 was also linked to lower odds of large for gestational age (LGA) with an adjusted OR of 0.44 (95% CI 0.23–0.84).
No significant association was found between above-range GWG24 and SGA or LGA.
