Although adolescent dieting is common, comparatively little is known a
bout its developmental course. The present study investigated the self
-perception and body shape satisfaction of 9-year old girls and boys i
n different weight categories. Two hundred and thirteen girls and 166
boys from three schools completed assessments of body-esteem, self-est
eem, body shape preference and dietary restraint. The children's body
weight and height were also measured. The heaviest children expressed
the most discontent, having a low body-esteem, a desire for thinness a
nd higher levels of dietary restraint. However, this desire for thinne
ss and associated dieting motivation was apparent in some children in
all weight categories. Furthermore, this pattern was more characterist
ic of girls than boys. By the age of nine, girls and boys already diff
er in their body shape satisfaction and differ in their body shape asp
irations. Initiatives to reduce obesity should acknowledge these early
and strongly-held gender differences or risk promoting the unwarrante
d pursuit of thinness by girls.
