Pregnancy outcomes of overweight and obese women aged 35 years or older - A registry-based study in Finland

Objective: To compare pregnancy outcomes of overweight and obese pregnant women aged 35 years or older to women aged less than 35 years old. Methods: A registry-based study covering years 2004-2008 including data on women >= 35 years (N = 45,718) compared to those = 30). In multivariable modelling, the main outcome measures were preterm delivery ( Results: Maternal overweight and obesity along with advanced maternal age (AMA) significantly increased the risks of preterm delivery, preeclampsia, foetal death, LGA and Caesarean as compared to women of average weight aged = 35 years to normal weight women of the same age, the rates of preeclampsia, preterm delivery Conclusions: The risks were increased by maternal age >= 35 years and both obesity and overweight. The combined effect of AMA and either overweight or obesity appeared to be a high risk state particularly for stillbirth and preterm delivery.
