Disordered Eating Assessment Core

饮食失调行为的公共卫生意义是巨大的。这些是相对常见的疾病，主要影响女性；总体上至少有2.5%的人口受到影响。(1，2)青少年和大学生中不太严重但仍有饮食紊乱的比例更高。基于人群的研究表明，7%的青春期女性和3%的青春期男孩报告使用不健康的体重控制行为，如通便或不吃饭，以控制自己的体重。饮食失调造成的经济和社会负担是巨大的。(8，9)医疗并发症非常常见，死亡率非常高。事实上，精心设计的研究发现神经性厌食症的死亡率每年超过0.5%(10，11)，最近的证据表明，其他饮食失调的死亡率也增加了。(12)此外，饮食失调可能对我们理解肥胖的原因、预防和治疗很重要。例如，肥胖者暴饮暴食和夜间进食的模式已经被发现超过50年了。 在过去的15-20年里，暴饮暴食现象一直是一个越来越引起人们兴趣和争议的话题。 总而言之，饮食失调的患病率很高，严重的医学和心理社会共病，以及对治疗和预防肥胖的重要影响。出于这些原因，饮食行为紊乱核心是该中心的一个有价值的组成部分。

The public health significance of disordered eating behavior is great. These are relatively common disorders, affecting primarily women; overall at least 2.5% ofthe population is affected.(1,2) Rates of less severe but still disordered eating among teens and college students are higher still. Population-based studies show that 7% of adolescent females and 3% of adolescent boys report using unhealthy weight control behaviors, such as purging or skipping meals, to manage their weight." The economic and social burdeps of eating disorders are substantial.(8,9) Medical complications are extremely common and the rate of mortality is very high. In fact, welldesigned studies have found a mortality rate in anorexia nervosa of over one half percent per year(10,11) and recent evidence documents elevated mortality in other eating disorders as well.(12) Moreover, disordered eating may be important to our understanding of the causes, prevention, and treatment of obesity. For example, patterns of binge eating and night eating in obese individuals have been recognized for over 50 years(13) The phenomenon of binge eating has been a topic of increased interest and controversy over the last 15-20 years. In summary, disordered eating has a high prevalence rate, significant medical and psychosocial co-morbidities, and important implications for treating and preventing obesity. For these reasons, a Disordered Eating Behavior Core is a valuable component ofthe center.
