To date, no known research has explored the link between binge eating and physical violence perpetration despite overlapping psychological constructs that underpin these behaviors (i.e., emotion regulation difficulties, impulsivity). Therefore, this study aimed to determine the association between binge eating and self-reported physical violence perpetration.
Cross-sectional data from four survey years (2016-2020) of the national (U.S.) Healthy Minds Study (N = 6210) were analyzed. Unadjusted (Independent samples t test) and adjusted (logistic regression) analyses were conducted to determine the associations between binge eating in the past four weeks and violence perpetration in the past 12 months, while adjusting for potential confounders.
The unadjusted mean number of days of binge eating was significantly higher among participants who reported physical violence perpetration (M = 2.6, SD = 5.2) compared to those who did not (M = 1.8, SD = 3.7). Logistic regression analysis demonstrated that each additional day of binge eating was associated with 5% higher odds (95% confidence interval 1.02-1.09) of self-reported physical violence perpetration, while adjusting for potential confounders.
Results from this study are the first known to identify an association between binge eating and physical violence perpetration among U.S. college students. Findings are supported by the potential mechanistic overlap of emotion regulation and impulsivity associated with both binge eating and violence perpetration, underscoring the need for more research.
迄今为止，尽管支撑这些行为的心理结构存在重叠（即情绪调节困难、冲动性），但尚无已知研究探讨暴饮暴食与实施身体暴力之间的联系。因此，本研究旨在确定暴饮暴食与自我报告的身体暴力行为之间的关联。
对美国全国性的健康心灵研究四个调查年份（2016 - 2020年）的横断面数据（N = 6210）进行分析。进行了未调整分析（独立样本t检验）和调整分析（逻辑回归），以确定过去四周内的暴饮暴食与过去12个月内的暴力行为之间的关联，同时对潜在混杂因素进行调整。
与未报告实施身体暴力的参与者相比，报告实施身体暴力的参与者未调整的暴饮暴食天数平均数显著更高（M = 2.6，标准差 = 5.2），而未实施暴力的参与者为（M = 1.8，标准差 = 3.7）。逻辑回归分析表明，在对潜在混杂因素进行调整的情况下，暴饮暴食每增加一天，自我报告实施身体暴力的几率就会高出5%（95%置信区间1.02 - 1.09）。
本研究结果首次发现美国大学生中暴饮暴食与实施身体暴力之间存在关联。情绪调节和冲动性在暴饮暴食和暴力行为中存在潜在的机制重叠，这一发现支持了上述结果，强调了需要进行更多研究。
