Duration of breastfeeding associated with obesity during adolescence.
The relationship between duration of breastfeeding and obesity (body mass index > or = 85 percentile) at adolescence was investigated in a white, rural population (n = 136) in which confounding by race was absent and confounding by socioeconomic status was expected to be minimal. Relevant data were abstracted from hospital charts. When examined independently, minimal (< or = 2 months) or no breastfeeding was positively associated with adolescent obesity (p < 0.03). This association was present in the lower but not the higher socioeconomic status group. However, when sex, birthweight, and socioeconomic status were included in a multiple regression model, duration of breastfeeding was no longer significantly associated with obesity during adolescence.
