Study objective-To assess the relative importance of heritable characteristics and lifestyle in the development of « maternal obesity » after pregnancy.
Setting-South east London, in the homes of mothers who had delivered their babies at either Guy's, Lewisham or St Thomas's hospitals.
Participants-Seventy four mothers of low antenatal risk who had been enrolled in the Antenatal Care (ANC) Project (a previous trial of antenatal care) during the first trimester of pregnancy, and who had subsequently been followed up 2.5 years after delivery.
Design-Information on parental obesity, psychosocial and sociodemographic factors as well as lifestyle, was gathered during a semi-structured interview at each mother's home.
Additional anthropometric and psychosocial data were taken from the existing ANC Project database.
These data were used to assess the relative importance of heritable characteristics and lifestyle on changes in maternal body weight from the beginning ofpregnancy to the follow up interview.
Main results-After adjusting for the effects of potential confounders and known risk factors for maternal obesity, women who selected larger silhouettes to represent their biological mothers were significantly more likely to have higher long term weight gains than those who selected thinner maternal silhouettes (r=0.083, p=0.004).
