Gestational weight gain and neonatal outcomes in different zygosity twins: a cohort study in Wuhan, China.

ABSTRACT:

Objective

To evaluate whether twin zygosity influences the association between neonatal outcomes and gestational weight gain (GWG) based on the Chinese guidelines in twin-pregnancy women.

Design

A retrospective cohort study. And it is not a clinical trial.

Setting

Women with twin pregnancies living in Wuhan, China.

Participants

A total of 5140 women who delivered live and non-malformed twins from 1 January 2011 to 31 August 2017 were included in this study.

Main outcome measure

The primary neonatal outcomes included paired small for gestational age (SGA, <10 th percentile birth weight for gestational age and sex), low birth weight (LBW, <2500 g) and gestational age (<33 weeks and <37 weeks). The association between GWG and neonatal outcomes was examined
