A weighty risk factor for preterm delivery
In the overweight mothers, the increased risk for pre-term delivery was more prominent in late preterm than early preterm deliveries.
The women were categorised based on their BMI as either underweight, normal weight, pre-obese, mild obese, moderate obese and advanced obese. Rates of pre-term delivery were 7.1%, 4.7%, 5.3%, 7.1%, 7.3% and 9.3%, respectively.
Advanced obese mothers had an increased risk for both early and late pre-term delivery.
The findings for both studies were presented at the US Society for Maternal-Fetal Medicine’s (SMFM) annual meeting.
