Food addiction is the clinical occurrence in which individuals develop physical and psychological dependencies on high fat, high sugar, and highly palatable foods. Past research has demonstrated a number of similarities between food addiction and drug use disorders including the activation of specific brain regions and neurotransmitters, disrupted neuronal circuitry, and behavioral indicators of addiction such as continued use despite negative consequences. The present study examined the role of impulsivity and emotion dysregulation in food addiction as both play salient roles in drug use disorders. Poisson regression analyses using data from 878 undergraduate students revealed negative urgency, the tendency to act impulsively when under distress, and emotion dysregulation positively predicted symptom count on the Yale Food Addiction Scale (Gearhardt, Corbin, & Brownell, 2009) whereas a lack of premeditation negatively predicted symptom count (all ps<0.05). Future research is needed to confirm precursors to eating episodes in food addiction, elucidate causal mechanisms, and support an explanatory model of food addiction.
食物成瘾是一种临床现象，即个体对高脂肪、高糖和美味的食物产生生理和心理依赖。过去的研究表明，食物成瘾和药物使用障碍之间存在许多相似之处，包括特定脑区和神经递质的激活、神经元回路的破坏以及成瘾的行为指标，如尽管有负面后果仍继续使用。本研究考察了冲动性和情绪失调在食物成瘾中的作用，因为它们在药物使用障碍中都起着显著作用。使用来自878名本科生的数据进行的泊松回归分析显示，消极紧迫感（即在痛苦时冲动行事的倾向）和情绪失调正向预测耶鲁食物成瘾量表（Gearhardt、Corbin和Brownell，2009）上的症状数量，而缺乏预谋则负向预测症状数量（所有p值<0.05）。未来需要进行研究以确认食物成瘾中进食发作的先兆，阐明因果机制，并支持食物成瘾的解释模型。
