Woo and colleagues have performed an interesting and thoughtful
analysis that helps elucidate the relationship between racial/
socioeconomic status, breastfeeding in infancy and adolescent BMI. I
wonder if there is study data on maternal or paternal BMI? This variable
is a key predictor of offspring BMI, and may be as important as
breastfeeding in predicting childhood BMI (1,2). Since there are
significant racial disparities in the rates of both maternal obesity and
breastfeeding in the US, maternal BMI may explain more differences in
adolescent BMI than breastfeeding (3,4). Could the authors address
this issue?
