Nagata JM, et al. - In this investigation, researchers used a nationally representative longitudinal sample from the United States to assess predictive factors of muscularity-oriented disordered eating behaviors in adolescent males and females and if there are differences according to sex. Out of 14,891 total participants, 22% of males and 5% of females reported any muscularity-oriented disordered eating behavior in young adulthood. Black race, exercising to gain weight, self-perception of being underweight, and lower body mass index z-score were factors recorded at adolescence that were linked to higher odds of muscularity-oriented disordered eating in both sexes. In addition, alcohol among males and depressive symptoms among females during adolescence were linked to higher odds of muscularity-oriented disordered eating in young adulthood. Overall, the authors concluded that interventions to prevent muscularity-oriented disordered eating behaviors may target at-risk youth, particularly black race youth or those who engage in weight gain exercise.
