目的利用美国具有全国代表性的纵向样本，确定青少年肌肉型饮食紊乱行为的预测因子，并检验性别差异。方法我们使用从基线收集的具有全国代表性的纵向队列数据（11-18岁，1994-1995年）和7年随访（18-24岁，2001-2002年）的国家青少年到成人健康纵向研究。我们检查了青少年人口统计学、行为和心理健康预测因素，这些因素是年轻成人肌肉发达型饮食紊乱行为的预测因素，这些饮食紊乱行为定义为吃得更多或不同以增加体重或体积，补充剂以增加体重或体积，或在7年随访时使用雄激素合成代谢类固醇。22%的男性和5%的女性在随访时报告了任何以肌肉为导向的饮食行为障碍。在青春期记录的因素与男性和女性肌肉型饮食失调的几率较高有前瞻性相关性，包括黑人种族，锻炼以增加体重，自我感觉体重不足，以及较低的体重指数z评分。此外，参与举重，旱冰，旱冰，滑板，或骑自行车;和酒精的男性和抑郁症状的女性在青春期与更高的几率的肌肉为导向的饮食失调在年轻adult.Conclusions干预措施，以防止肌肉为导向的饮食失调行为可能针对高危青年，特别是那些黑人种族或从事运动，以增加体重。未来的研究应该检查纵向健康结果与肌肉为导向的饮食失调行为。
Objective To determine adolescent predictors of muscularity-oriented disordered eating behaviors in young men and women using a nationally representative longitudinal sample in the United States and to examine differences by sex.Method We used nationally representative longitudinal cohort data collected from baseline (11-18 years old, 1994-1995) and 7-year follow-up (18-24 years old, 2001-2002) of the National Longitudinal Study of Adolescent to Adult Health. We examined adolescent demographic, behavioral, and mental health predictors of young adult muscularity-oriented disordered eating behaviors defined as eating more or differently to gain weight or bulk up, supplements to gain weight or bulk up, or androgenic anabolic steroid use at 7-year follow-up.Results Of the 14,891 included participants, 22% of males and 5% of females reported any muscularity-oriented disordered eating behavior at follow-up in young adulthood. Factors recorded at adolescence that were prospectively associated with higher odds of muscularity-oriented disordered eating in both sexes included black race, exercising to gain weight, self-perception of being underweight, and lower body mass index z-score. In addition, participation in weightlifting; roller-blading, roller-skating, skate-boarding, or bicycling; and alcohol among males and depressive symptoms among females during adolescence were associated with higher odds of muscularity-oriented disordered eating in young adulthood.Conclusions Interventions to prevent muscularity-oriented disordered eating behaviors may target at-risk youth, particularly those of black race or who engage in exercise to gain weight. Future research should examine longitudinal health outcomes associated with muscularity-oriented disordered eating behaviors.
