Perceived weight in youths and risk of overweight or obesity six years later.

OBJECTIVE

To examine the association between perceived overweight in adolescents and the development of overweight or obesity later in life.

METHODS

This paper uses data from a prospective, two-wave cohort study. Participants are 2445 adolescents 11-17years of age who reported perceived weight at baseline and also had height and weight measured at baseline and at follow-up six years later sampled from managed care groups in a large metropolitan area.

RESULTS

Youths who perceived themselves as overweight at baseline were approximately 2.5 times as likely to be overweight or obese six years later compared to youths who perceived themselves as average weight (OR=2.45, 95% CI=1.77-3.39), after adjusting for weight status at baseline, demographic characteristics, major depression, physical activity and dieting behaviors. Those who perceived themselves as skinny were less likely to be overweight or obese later (OR=0.36, 95% CI=0.27-0.49).

CONCLUSIONS

Perceived overweight was associated with overweight or obesity later in life. This relationship was not fully explained by extreme weight control behaviors or major depression. Further research is needed to explore the mechanism involved.
