这项前瞻性研究调查了青春期后期女孩暴饮暴食和腹泻的发病年龄，并测试了节食和消极情感是否能预测这些结果。在最初无症状的青少年中，5%报告发生了客观暴饮暴食，4%报告发生了主观暴饮暴食，4%报告发生了腹泻。暴饮暴食发生的高峰风险发生在16岁，而腹泻发生的高峰风险发生在18岁。青少年更经常报告单一症状而不是多种症状的发作，症状是偶发的。节食和消极情绪预示着暴饮暴食和净化的开始。研究结果表明，青春期后期是暴食症行为发生的高风险时期，并确定了这些结果的可改变的风险因素。
This prospective study examined age of onset for binge eating and purging among girls during late adolescence and tested whether dieting and negative affectivity predicted these outcomes. Of initially asymptomatic adolescents, 5% reported onset of objective binge eating, 4% reported onset of subjective binge eating, and 4% reported onset of purging. Peak risk for onset of binge eating occurred at age 16, whereas peak risk for onset of purging occurred at age 18. Adolescents more often reported onset of a single symptom rather than multiple symptoms, and symptoms were episodic. Dieting and negative affectivity predicted onset of binge eating and purging. Findings suggest that late adolescence is a high-risk period for onset of bulimic behaviors and identify modifiable risk factors for these outcomes.
