Bariatric surgery is efficacious for the treatment of severe obesity; however, little empirical research exists describing the demographic, psychosocial, and cognitive characteristics of patients presenting for the surgery. One hundred and sixty-nine morbidly obese patients seeking bariatric surgery underwent a presurgical psychological assessment, including cognitive testing. Morbidly obese individuals seeking bariatric surgery were similar in education, income status, and IQ compared with normative data. IQ was average, did not correlate with body mass index, and reflected a normal distribution. As a group, bariatric surgery patients endorsed minimal levels of depression and low levels of psychopathology. Obese individuals did demonstrate specific cognitive deficits on tests of executive function (e.g., problem solving and planning) when compared with normative data. This data suggests that bariatric surgery patients differ very little from other surgical populations on most demographic and psychosocial variables. The data does provide evidence for specific cognitive deficits in the area of executive functions at baseline in morbidly obese adults seeking bariatric surgery.
减肥手术对于治疗重度肥胖症是有效的；然而，几乎没有实证研究描述寻求该手术的患者的人口统计学、心理社会和认知特征。169名寻求减肥手术的病态肥胖患者接受了术前心理评估，包括认知测试。与标准数据相比，寻求减肥手术的病态肥胖个体在教育程度、收入状况和智商方面相似。智商处于平均水平，与体重指数无关，呈正态分布。作为一个群体，减肥手术患者的抑郁水平极低，心理病理学水平也较低。与标准数据相比，肥胖个体在执行功能测试（如解决问题和规划）中确实表现出特定的认知缺陷。这些数据表明，减肥手术患者在大多数人口统计学和心理社会变量上与其他手术人群差异很小。这些数据确实为寻求减肥手术的病态肥胖成年人在基线时执行功能方面存在特定认知缺陷提供了证据。
