Twelve-year Follow-up on the Treatment of Obese Pregnant Women (TOP) Study

The initial study (Treatment of Obese Pregnant women (TOP) study) was performed at Hvidovre Hospital, University of Copenhagen in 2009-12 and included 425 pregnant women with pre-gestational BMI ≥ 30kg/m2 in gestational week 11-14. They were randomized 1:1:1 into: 1) a low-calorie Mediterranean-style diet and pedometer assisted physical activity (PA) intervention 2) a pedometer assisted PA intervention alone or 3) no intervention (control). Primary outcome was gestational weight gain (GWG). 389 women completed the study. The participants (both mother and child in pair) who completed the initial TOP study will be invited to a 3-hour examination now 12 years after the intervention during pregnancy to evaluate the effect of the intervention on both mother and child long term.
