To investigate the effect of pre-pregnancy maternal overweight on perinatal outcomes in twin pregnancies.
Study Design
A retrospective population-based study was conducted comparing maternal and neonatal outcome in women carrying twins with and without pre-pregnancy overweight. Overweight was defined as pre-pregnancy body mass index (BMI) of 25 kg/m2 or more. Deliveries occurred in a tertiary medical center between the years 2011 and 2012.
214 women carrying twins were included in the current study; of these, 100 (46.7%) had pre-pregnancy BMI ≥25 kg/m2. Mothers with pre-pregnancy overweight were older and gained less weight throughout the pregnancy (Table). Overweight parturients had higher rate of gestational diabetes mellitus (GDM) and cesarean deliveries. Neonatal outcome, however, was comparable between the groups (Table). Using a multivariable model, controlling for diabetes mellitus and maternal age, pre-pregnancy overweight was noted as an independent risk factor for cesarean delivery (adjusted OR=2.2, 95% CI 1.2-3.9; P=0.008).
Pre-pregnancy overweight increases the risk of GDM and cesarean delivery in women carrying twins. However, in our population, overweight was not associated with adverse neonatal outcome.
