Longitudinal concomitants of incorrect weight perception in female and male adolescents

The aim of the present study was to analyse the longitudinal concomitants of incorrect weight perception, depressive symptoms, social anxiety, self-esteem, and eating disorders in adolescents. A prospective follow-up study on 283 female and 312 male adolescents aged 15 comprising questionnaires directed at the whole study population and subsequent personal interviews with adolescents found to be screen-positive for eating disorders, at both baseline and three-year follow-up. Body mass index was combined with weight perception to classify adolescents with incorrect weight perception. Twenty-nine percent of females incorrectly perceived themselves as overweight and 14% of males incorrectly as underweight. Incorrect weight perception was in females related to depressive symptoms, social anxiety, eating disorders, and low self-esteem. Males with incorrect weight perception experienced more social anxiety at the follow-up than their counterparts with correct weight perception. Recognition of incorrect weight perception is important for prevention of depression, social anxiety, and eating disorders.
