OBJECTIVE: To document the prevalence of dieting and to compare body composition markers, dietary intakes and eating behaviours across dieting categories. DESIGN: Prospective, cross-sectional study. SETTING: Twenty-four randomly selected secondary public schools located in Attica, Greece. SUBJECTS: Anthropometric, medical and dietary information was obtained from 857 (54·9 % females) adolescents (mean age 13·4 (sd 0·9) years). Meal patterns, eating behaviours and eating style score, reflecting conditions around eating, were assessed. Adolescents were asked about their dieting involvement and were categorised as 'never dieters', 'current dieters' or 'past dieters'. RESULTS: Overall, 20·1 % of the adolescents were currently dieting and 15·2 % reported past dieting. Mean BMI and body fat percentage of never dieters were significantly lower than those of both groups of dieters (P < 0·001). Breakfast skipping (χ 2 = 10·92, P = 0·004) and eating large quantities of food (χ 2 = 7·18, P = 0·028) differed significantly across dieting groups in females. Significant differences in dinner skipping were observed in both males (χ 2 = 10·55, P = 0·005) and females (χ 2 = 20·91, P < 0·001). Female past dieters had significantly higher eating style scores than never dieters (P = 0·010) and current dieters (P = 0·042), indicating less well-structured feeding practices and food intake for reasons other than hunger. CONCLUSIONS: The present study showed a high prevalence of dieting among adolescents. Current dieters and past dieters had higher BMI and body fat percentage than never dieters. Eating behaviours differed significantly depending on dieting involvement, especially in females; while an apparently healthier, ordered eating style adopted by dieters during the dieting period seemed not to be maintained in the long term.
