Abstract:Objective:
To identify the optimal weight gain at the end of the second trimester.
Design:
This was a population-based cohort study from the antenatal care system in Tianjin, China. We calculated gestational weight gain (GWG) based on the weight measured in the first trimester and the end of the second trimester. Restricted cubic spline analysis was performed to model the possible nonlinear relationships between GWG and adverse outcomes. The optimal GWG was defined as the value of the lo… Show more
