Sumario:AIM: The aim of this study was to evaluate if overweight and obesity in the offspring is reduced by a low-intensity antenatal primary care intervention with focus on diet and physical activity for pregnant women with obesity, comparing children to mothers receiving the intervention with children to mothers who did not. METHODS: This study is a follow-up of children 2.5 years of age after their mothers’ participation in a non-randomised controlled intervention intending to limit gestational weight gain. All study participants received standard antenatal care. The intervention group received lifestyle support via motivational talks with midwife and support from dietician. Data on child weight were collected by medical records, letter and phone. RESULTS: There was no significant difference between the groups 2.5 years after intervention (International Obesity Task Force ISO-BMI 25 (child BMI corresponding to adult BMI of 25): 20% vs. 21%; ISO-BMI 30: 4.6% vs. 1.3%). The mother’s BMI at the beginning of pregnancy significantly influenced child BMI at 2.5 years (r = 0.13, p = 0.014, r(2) = 0.017). For each unit of increase in maternal BMI at enrollment, the probability of child ISO-BMI ≥ 25 increased by 7.5% (p = 0.021) and of ≥ 30, by 12.9% (p = 0.017). CONCLUSION: The frequency of overweight and obesity of the children at 2.5 years of age was significantly correlated to the mother’s BMI, but not correlated to the mothers’ participation in the antenatal lifestyle intervention. Thus, it seems important to address obesity and lifestyle issues before and between pregnancies. Trial registration The study has been registered at ClinicalTrials.gov, Identifier: NCT03147079.
