INTRODUCTION: Association between parent's Body Mass Index (BMI) and their children, has been widely documented. Individual, familiar and structural factors play a role in this relation. We analyzed the association between maternal BMI change during the first year post-partum and their offspring's growth-trajectories and energy intake in their first five years of life.
OBJECTIVE: Compare growth-trajectories and children's caloric intake according to post-partum mother´s BMI classification.
METHODS: The anthropometric assessment was taken in 935 mother-child pairs along the study period. Mothers were classified into four groups according to their BMI-trajectories in the post-partum. Children's weight for height z-scores (WHZ) was compared among groups using random-effects regression models. A longitudinal comparison of children's caloric intake by the maternal group was carried out.
RESULTS: At 42 months of age, infants from mothers that remained overweight during the first year post-partum had, on average, 0.61 SD higher WHZ than those from mothers who remained in a recommended BMI group (R-BMI) in the same period. At 60 months of age, children´s prevalence of obesity was almost twice in the maternal overweight group vs R-BMI group (14.2% and 7.3% respectively). Chances for a child of having an over caloric intake were 36.5% (95% IC: 6.6%, 74.8%) and significantly higher among children from overweight mothers than those from R-BMI mothers. The difference in children's WHZ trajectory remained significant after adjusting for caloric intake, suggesting that contextual factors play a role in shaping children's obesity. A concurrent ethnographic study with the study subjects provides suggestions as to what these factors might be, including changes in the food landscape.
CONCLUSION: Children from overweight mothers tended to have a more caloric diet yielding a higher propensity to obesity. Contextual factors such as food landscape might contribute to childhood obesity beyond having an overweight mother. Pregnancy and post-partum is a window of opportunity for interventions to decrease the incidence of children's overweight.
