GDM modified the associations of gestational weight gain with pregnancy outcomes: a population-based cohort study.

ABSTRACT:

Background

The timing of gestational diabetes mellitus (GDM) screening may impact the progression of gestational weight gain (GWG). Additionally, it remains unclear whether the associations of GWG with pregnancy outcomes vary based on GDM status. Thus, this study aims to investigate the effect of GDM on the associations between GWG in different periods and pregnancy outcomes.

Methods

GWG was categorized into: total, before and after the oral glucose tolerance test (OGTT). The GWG rate for different periods was calculated by dividing the total GWG by the corresponding gestational week intervals, and was further classified as inadequate GWG (IGWG), normal GWG (NGWG), or excessive GWG (EGWG). Logistic regression models were used to analyze the associations of GWG rate and GWG c
