This study analyzed the association of body size dissatisfaction with body mass index, dietary pattern, and physical activity in adolescents. A sample of 1074 participants between 10 and 17 years of age was recruited. Body size dissatisfaction was assessed with the silhouettes' scale. Dietary pattern, physical activity, and socioeconomic status were assessed with questionnaires. Body mass index was measured objectively. The prevalence of body size dissatisfaction was 77.0%, where 29.8% desired to increase body size and 47.2% desired to decrease body size. Adolescents who desired to increase body size were more likely to consume vegetables and sweets and less likely to be in the highest quartile of physical activity than satisfied adolescents. Adolescents who desired to reduce body size were more likely to report lower fruit and vegetable consumption than satisfied adolescents. Health actions aiming to reduce body dissatisfaction in adolescents should address improvement in dietary pattern and physical activity engagement, considering that desires to increase or decrease body size were differently associated in this study.
