The present study investigated the occurrence of life events preceding the onset of disturbed eating in binge-eating disorder (BED). In a case-control design, 162 matched pairs of black and white women with BED and women with no current psychiatric disorder, and 107 matched pairs of women with BED and a current general psychiatric disorder were recruited from the community for the New England Women's Health Project. Life events in the year before the onset of disturbed eating were assessed retrospectively with an investigator-based interview. Women with BED reported exposure to a significantly greater number of life events during the year before onset of eating disturbances than both the non-psychiatric and psychiatric control women during the same period of time in their lives. Women with BED had a significantly higher risk of exposure to certain specific life events (e.g., critical comments about shape, weight, or eating; stress related to work, school or other sources; major changes in life circumstances and relationships; physical abuse; and feeling unsafe in a variety of settings) than the non-psychiatric control women, while differences between the BED and the psychiatric control group were less marked. There was no evidence for race-specific exposure to antecedent life events. The results suggest that a greater number and certain specific types of life events increase risk for the subsequent development of BED.
本研究调查了暴饮暴食障碍（BED）中饮食紊乱发作前生活事件的发生情况。在一项病例对照研究中，从社区招募了162对匹配的患有BED的黑人和白人女性与无当前精神疾病的女性，以及107对匹配的患有BED的女性和患有当前一般精神疾病的女性，用于新英格兰女性健康项目。通过基于研究者的访谈对饮食紊乱发作前一年的生活事件进行回顾性评估。患有BED的女性报告称，在饮食紊乱发作前一年中接触到的生活事件数量明显多于非精神疾病和精神疾病对照女性在其生命中同一时期接触到的生活事件数量。与非精神疾病对照女性相比，患有BED的女性接触某些特定生活事件（例如，关于体型、体重或饮食的批评性评论；与工作、学校或其他来源相关的压力；生活环境和人际关系的重大变化；身体虐待；以及在各种环境中感到不安全）的风险显著更高，而BED组与精神疾病对照组之间的差异则不太明显。没有证据表明存在种族特异性的先前生活事件暴露情况。结果表明，更多数量和某些特定类型的生活事件会增加随后发生BED的风险。
