Dietary Adherence, Glycemic Control, and Psychological Factors Associated with Binge Eating Among Indigenous and Non-Indigenous Chileans with Type 2 Diabetes

Int J Behav Med. 2015 Dec;22(6):792-8. doi: 10.1007/s12529-015-9478-y.


Background: Despite the strong association between obesity and binge eating, limited research has examined the implications of binge eating on dietary adherence and psychological factors in ethnically diverse type 2 diabetes patients.

Purpose: This study investigated the prevalence of binge eating and its association with dietary adherence, glycemic control, and psychological factors among indigenous and non-indigenous type 2 diabetes patients in Chile.

Method: Participants were 387 indigenous (Mapuche) and non-indigenous (non-Mapuche) adults with type 2 diabetes. Self-report measures of binge eating, dietary adherence, diet self-efficacy, body image dissatisfaction, and psychological well-being were administered. Participants' weight, height, and glycemic control (HbA(1c)) were also obtained.

Results: Approximately 8 % of the type 2 diabetes patients reported binge eating. The prevalence among Mapuche patients was 4.9 %, and among non-Mapuche patients, it was 9.9 %. Compared to non-binge eaters, binge eating diabetes patients had greater body mass index values, consumed more high-fat foods, were less likely to adhere to their eating plan, and reported poorer body image and emotional well-being.

Conclusion: Results of this study extend previous research by examining the co-occurrence of binge eating and type 2 diabetes as well as the associated dietary behaviors, glycemic control, and psychological factors among indigenous and non-indigenous patients in Chile. These findings may increase our understanding of the health challenges faced by indigenous populations from other countries and highlight the need for additional research that may inform interventions addressing binge eating in diverse patients with type 2 diabetes.
