Background: Maternal prepregnancy obesity (BMI 30kg/m(2)) and excessive gestational weight gain (GWG) have shown a strong positive association with a higher BMI and risk of obesity in the offspring. The aim of this study is to estimate the effect of a GWG restriction program for obese pregnant women on the childrens BMI at 5 years of age and weight-for-length/height (WL/H) development from 2 months of age until 5 years of age. Methods: This was a follow-up study of 302 children (137 children in an intervention group and 165 children in a control group) whose mothers participated in a weight gain restriction program during pregnancy. Results: BMI at five years of age did not differ between girls and boys in the intervention and control group. The degree of maternal GWG, amp;lt;7kg or 7kg, did not affect the offsprings WL/H. Compared with Swedish reference data, just over half of the children in both the intervention and control group had a BMI within the average range, whereas slightly more than one-third of the children had a higher BMI. Conclusion: Despite a comprehensive gestational intervention program for obese women containing individual weekly visits and opportunity to participate in aqua aerobic classes, there were no differences between BMI or weight development among the offspring at 5 years of age in the intervention and control group.
