More pregnancy woes for the overweight

Australian and US authors conducted a secondary analysis of an observational study stratifying women pre-pregnancy into different BMI categories and then monitoring their outcomes. 

Among the 4500 women, 551 had a BMI of 30—34.9, 317 had a BMI of 35—39.9, 167 had a BMI of 40—44.9, and 142 had a BMI greater than 45. 

The researchers found that compared to women with a normal BMI, women who were overweight or obese were at an increased risk for specific pregnancy complications and the threshold for these outcomes could be predicted.
