Mothers who had increased their BMI by 3 units or more during the previous two years -- a weight gain of 17 pounds or more for a woman of average height -- between their fist and second pregnancy were 1.8 times more likely to have pre-eclampsia (hypertension and other damaging effects) during pregnancy according to a large Swedish study.

"Our results provide robust epidemiological evidence for advocating weight loss in overweight and obese women who are planning to become pregnant and, to prevent weight gain before pregnancy in women with healthy BMIs," the authors of the study concluded. Subjects

Subjects: 151,025 women who had two children

The study analyzed data from 151,025 women in Sweden “who had their first two consecutive singleton births between 1992 and 2001.”
