Several studies show an association between obesity, impulsivity, and anger. The condition of obesity has moreover an important correlation with Eating Disorders (EDs), the most frequent of which is Binge Eating Disorder (BED). Obese patients seem to express peculiarities regarding the expression of some emotional processes, including impulsivity, aggression and anger, compared with regular-weight patients and those without an ED.
This is a cross-sectional study carried out on a population of 47 obese patients undergoing bariatric surgery. Patients underwent a psychiatric evaluation at the outpatient clinics of the Section of Psychiatry, Clinical Psychology and Psychiatric Rehabilitation of the University Hospital of Perugia. Levels of anger and impulsivity were characterized using the STAXI-2 and BIS-11 scores. Scores were compared based on sex, the presence/absence of EDs and on the presence/absence of psychiatric disorders attested during the evaluation.
No statistically significative difference were detected on STAXI-2 and BIS-11 scores comparing men and women. People diagnosed with EDs had higher scores in the subscores of attention, cognitive complexity, motor impulsivity, non-planning impulsivity, and in the BIS-11 total score. No differences were detected in the STAXI-2 scores. When comparing patients on the presence/absence of psychiatric comorbidities, obese patients with a psychiatric diagnosis had higher scores on the impulsivity measures, but also a higher value on the ER index of the STAXI-2.
Obese subjects undergoing bariatric surgery represent a fragile population that must be carefully evaluated from a psychiatric point of view. Indeed, the co-existence of psychiatric comorbidities may underpin the present of trait-like characteristics, such as impulsivity and anger, that should be carefully considered when proposing treatment strategies.
多项研究表明肥胖、冲动和愤怒之间存在关联。肥胖状况与饮食失调（EDs）有重要的相关性，其中最常见的是暴食障碍（BED）。与正常体重患者和没有 ED 的患者相比，肥胖患者在表达某些情绪过程方面似乎表现出一些特殊性，包括冲动、攻击性和愤怒。
这是一项在接受减重手术的 47 名肥胖患者中进行的横断面研究。患者在佩鲁贾大学医院的精神病学、临床心理学和精神病康复科的门诊接受了精神病评估。使用 STAXI-2 和 BIS-11 评分来描述愤怒和冲动水平。根据性别、EDs 的存在与否以及评估期间存在/不存在的精神障碍，对评分进行比较。
在 STAXI-2 和 BIS-11 评分方面，男性和女性之间没有统计学上的显著差异。被诊断为 ED 的人在注意力、认知复杂性、运动冲动、非计划冲动和 BIS-11 总分的子分数中得分较高。STAXI-2 评分没有差异。在比较有无精神共病的患者时，有精神诊断的肥胖患者在冲动测量方面得分较高，但 STAXI-2 的 ER 指数也较高。
接受减重手术的肥胖患者是一个脆弱的群体，必须从精神病学的角度进行仔细评估。事实上，精神共病的共存可能支持特质特征的存在，如冲动和愤怒，在提出治疗策略时应仔细考虑这些特征。
