This study assessed the relationships between binge eating disorder (BED) and eating self-efficacy in a sample of patients prior to bariatric surgery. The study also examined the extent that BED status accounted for variance in self-efficacy after controlling for demographic factors (age, sex and race), physical variables (comorbidities and body mass index [BMI]) and depressive symptoms. This was a cross-sectional study of pre-surgical data from patients seeking bariatric surgery at a university-based healthcare system (N = 98; mean ± SD age of 46.2 ± 12.5 years; BMI of 45.4 ± 7.2 kg/m ; 86.7% female; and 60.2% of patients self-identified as White). Patients completed the Weight and Lifestyle Inventory (WALI), Beck Depression Inventory-II (BDI-II) and Weight Efficacy Lifestyle Questionnaire. Of the total sample, 15.3% met criteria for BED, 33.7% had subthreshold BED and 51.0% were free of this disorder. In adjusted analyses, total self-efficacy was significantly lower in patients with subthreshold BED (B ± SE = -15.88 ± 7.23, p = .03) and individuals with BED (B ± SE = -35.07 ± 10.23, p = .001) than in those without BED. Patients with BED, compared to those without, had significantly worse scores (in adjusted analyses) on the self-efficacy subscales of negative emotions (p = .003), availability of food (p < .001), social pressure (p = .004) and positive activities (p = .03). In patients seeking bariatric surgery, total self-efficacy scores were significantly lower in patients with BED and subthreshold BED than those without BED. The results suggest that eating self-efficacy may be an important factor to target in patients with BED who seek bariatric surgery.
本研究评估了暴食障碍（BED）与拟接受减重手术的患者术前饮食自我效能之间的关系。研究还考察了在控制人口统计学因素（年龄、性别和种族）、身体变量（合并症和体重指数[BMI]）和抑郁症状后，BED 状态对自我效能的变异程度的解释程度。这是一项对寻求大学医疗系统减重手术的患者术前数据进行的横断面研究（N=98；平均年龄为 46.2±12.5 岁；BMI 为 45.4±7.2kg/m；86.7%为女性；60.2%的患者自认为是白人）。患者完成了体重和生活方式问卷（WALI）、贝克抑郁量表第二版（BDI-II）和体重效能生活方式问卷。在总样本中，15.3%符合 BED 标准，33.7%有亚阈值 BED，51.0%没有这种障碍。在调整分析中，亚阈值 BED 患者的总自我效能显著较低（B±SE=-15.88±7.23，p=0.03），BED 患者（B±SE=-35.07±10.23，p=0.001）的自我效能也显著低于无 BED 患者。与无 BED 患者相比，BED 患者的自我效能子量表（在调整分析中）在负性情绪（p=0.003）、食物可及性（p<0.001）、社会压力（p=0.004）和积极活动（p=0.03）方面的得分明显更差。在寻求减重手术的患者中，BED 和亚阈值 BED 患者的总自我效能评分明显低于无 BED 患者。结果表明，在寻求减重手术的 BED 患者中，饮食自我效能可能是一个重要的治疗靶点。
