Abstract
AbstractObjective:To assess the longitudinal association between parental BMI and offspring’s BMI, in EPACI Portugal 2012.Design:Longitudinal study with retrospective collection of children’s anthropometry data since birth. Children’s anthropometric data were gathered from individual child health bulletins, and parents’ anthropometrics were self-reported. Children’s and parents’ BMI were classified according to WHO cut-offs. Linear mixed models with random intercept and slope for age were applied to quantify the association between parental BMI and children BMI Z-score (zBMI).Setting:EPACI Portugal 2012.Participants:Representative sample from the Portuguese population (n 2230) aged from 12 to 36 months.Results:58·9 % of the fathers and 35·6 % of the mothers were overweight (OW) or obese. Prevalence of infants who were, at least, at risk of OW increased from 17·0 % to 30·3 % since birth to 12 months. About half of the mothers with pre-pregnancy OW and obesity (OB) gained gestational weight above the recommendations. The children from mothers with gestational weight gain (GWG) below the recommendations showed a −0·15 SD lower zBMI (95 % CI −0·23, −0·06) in early life, comparing with mothers within GWG recommendations. Children of obese mothers were more likely to present a higher zBMI (0·24 SD, 95 % CI 0·13, 0·35) throughout the first months of life.Conclusions:A high prevalence of OW and OB was observed in Portuguese young adults and toddlers. Mothers’ pre-pregnancy BMI and insufficient GWG had a direct effect on offspring BMI. Early effective interventions are needed in order to prevent the transgenerational transmission of OB.
