ELLIOTT, KRISTEN G, CHRIS L KJOLHEDE, EFFIE GOURNIS, KATHLEEN M RASMUSSEN. Duration of breastfeeding associated with obesity during adolescence.
The relationship between duration of breastfeeding and obesity (body mass index 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 (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.
