Gender and weight concerns in early and middle adolescence: links with well-being and family characteristics.

Studied sex and developmental differences in weight concerns in early and middle adolescence and links between concerns and adolescent well-being and family experiences. Participants were mothers, fathers, and older and younger siblings (Ms = 15 and 12.5 years, respectively) from 197, Caucasian, working-middle class, 2-parent families. Parents rated their gender role attitudes and adolescents rated their weight concerns, well-being, gender role orientations, and physical development. Girls reported more concerns than boys; body mass index (BMI) correlated with weight concerns for all youth. Controlling for BMI and pubertal status, weight concerns were linked to older girls' well-being; with physical characteristics controlled, mothers' gender attitudes explained older girls' weight concerns, and siblings' weight concerns explained those of older and younger girls and boys.
