The study is a follow-up of a Randomized Controlled Trial (RCT) performed in 2007-10 - the "Lifestyle in Pregnancy" LiP study. The LiP study included 360 pregnant women with BMI ≥30 kg/m2 from Odense University Hospital and Aarhus University Hospital. The women were randomized to intervention with low-calorie diet and physical activity from gestational age 10-14 in pregnancy and until delivery - or to a standard care control group. The objective of the LiPO-Teen project is to perform a clinical follow-up study of the eligible 301 mothers who completed the trial until delivery with a liveborn child, and their 14 year-old offspring. The overall ambition is to understand whether lifestyle intervention in pregnancy prevents obesity and its complications across generations, with a specific focus on modifiable factors.
