Self-esteem has been hypothesized to be lower in obese adolescents rel
ative to their normal weight peers and to be an important factor in pr
eventing or reversing obesity. The present study examined the relation
ship between obesity and self-esteem cross-sectionally and prospective
ly over three years in a cohort of 1278 adolescents in grades 7 to 9 a
t baseline. Cross-sectional analyses revealed an inverse association b
etween physical appearance self-esteem and body mass index in both mal
es and females. In females, body mass index was inversely associated w
ith global self-esteem, close friendship, and behavioral conduct self-
esteem. In males, body mass index was inversely associated with athlet
ic and romantic appeal self-esteem. Prospectively, in females, physica
l appearance and social acceptance self-esteem at baseline were invers
ely related to body mass index three years later. Baseline self-esteem
was unrelated prospectively to change in body mass index in males, Al
l associations were modest in magnitude. These results suggest that in
a middle class white sample of adolescents, self-esteem specific to p
hysical appearance is modestly associated with body mass index. Low se
lf-esteem does not appear to predict the development of obesity over t
ime.
