Binge eating behavior is a public health concern with serious physical and mental health consequences. Certain personality traits have been found to contribute to the development of eating disorders in clinical samples of youth, but little is known about associations between personality traits and binge eating in the general adolescent population. We examined the associations of neuroticism and impulsivity-both independently and in combination-with lifetime prevalence of binge eating, using nationally representative, cross-sectional data from the National Comorbidity Survey: Adolescent Supplement (n=437). Neuroticism and impulsivity were each significantly associated with lifetime prevalence of binge eating (adjusted prevalence ratio [aPR]=1.11, confidence interval [CI]=1.07, 1.15, p<0.001; aPR=1.06, CI=1.04, 1.09, p<0.001, respectively). The combination of high neuroticism and high impulsivity was associated with higher lifetime binge eating than the combination of low neuroticism and low impulsivity (aPR=3.72, CI=2.45, 5.65, p<0.001), and this association was stronger for female than male adolescents (females: aPR=5.37, CI=3.24, 8.91, p<0.001 vs. males: aPR=2.45, CI=1.43, 4.22, p=0.002). Our findings have implications for informing theories of etiology and interventions to target binge eating behaviors.
暴饮暴食行为是一个公共卫生问题，会对身心健康造成严重后果。在青少年临床样本中，已发现某些人格特质会导致饮食失调，但对于一般青少年人群中人格特质与暴饮暴食之间的关联却知之甚少。我们使用来自全国共病调查：青少年补充调查（n = 437）的具有全国代表性的横断面数据，研究了神经质和冲动性（分别以及两者结合）与暴饮暴食终生患病率之间的关联。神经质和冲动性各自均与暴饮暴食终生患病率显著相关（调整患病率比[aPR]=1.11，置信区间[CI]=1.07, 1.15，p<0.001；aPR=1.06，CI=1.04, 1.09，p<0.001）。高神经质和高冲动性的组合与暴饮暴食终生患病率之间的关联高于低神经质和低冲动性的组合（aPR=3.72，CI=2.45, 5.65，p<0.001），并且这种关联在女性青少年中比男性青少年中更强（女性：aPR=5.37，CI=3.24, 8.91，p<0.001；男性：aPR=2.45，CI=1.43, 4.22，p=0.002）。我们的研究结果对于为暴饮暴食行为的病因理论和干预措施提供信息具有启示意义。
