Association between child/adolescent overweight/obesity and conduct disorder: A systematic review and meta-analysis.

Based on the high-quality cross-sectional data, overweight and obesity are associated with conduct disorder among children and adolescents, affecting boys more frequently than girls. Results of the longitudinal analysis indicated possible association in boys, while girls seem to be protected from conduct disorder. However, these results are very unreliable, indicating the need of well-designed longitudinal studies to elucidate the pattern of association between these disorders.
