In spite of the low prevalence of overweight (10% males and 6% females), many adolescents reported themselves to be overweight: more girls (27%) than boys (12.5%) (P < 0.05) by Q2 (6.26) were cognitively inclined to weight loss even though they were not overweight (body mass index, BMI > 25 kg/m2). Adolescents desired a slimming of the abdomen (82% males and 52% females), thighs (18% boys and 39% girls), hips (6% and 18% males and females, respectively) and buttocks (23% males and 42% females).
