3. Résumé

According to the authors,«[c]ompared with parental care, children who attended a center-based childcare had higher odds of being overweight/obese in childhood (4-10 years old). Additionally, children being taken care of by relatives had higher odds of being overweight/obese, although with greater uncertainty […]. There was no association between family-based childcare and nanny/babysitter and children’s overweight/obesity over the 6-year period of follow-up. […] Hours in center- based childcare and in relative care were significantly associated with overweight/obesity in childhood. We re-analyzed the data while excluding very pre-term babies […] and pre-term babies […], and the results were unaltered. The rate of overweight/obesity increased significantly with age, […] but the child’s age by childcare exposure interaction was not significant […].» (p. 755-756)
