Abstract
Bulimic behavior and the associated experience of one's own body are of great importance in the course of surgical treatment for obesity. This study determined the predictive role of multidimensional body image on bulimic-type eating behaviors among individuals scheduled for the surgical treatment of obesity. This study was conducted in a clinical setting on a group of 100 obese patients who were treated at the Centre for the Surgical Treatment of Obesity at the University Hospital in Krakow (Poland) and were qualified for bariatric surgery. Body image was examined with Cash's Multidimensional Body-Self Relations Questionnaire (MBSRQ) and bulimic behavior with David M. Garner's Eating Attitudes Test (EAT-26). Part A of the EAT-26 focused only on the bulimia and food preoccupation scale. Part B included sex, age, and body mass index (BMI) in the predictive model. A stepwise multiple regression analysis was conducted to assess psychological predictors of eating behavior. For binary variables, a logistic regression analysis was conducted for the whole group and for the women's group alone. Owing to the small sample size of men, regression analyses were not conducted. Higher values were observed in the Appearance Orientation dimension among women when compared to men. Appearance evaluation and age were found to be significant predictors for bulimic behaviors in the whole group. In regression models for behavior in the last 6 months, the predictors were found to be Health Evaluation and Appearance Orientation for laxative use, and Overweight Preoccupation for vomiting for weight control. Health-promoting behaviors in obesity treatment were conditioned as follows: for exercise, the predictors were sex and Fitness Orientation and for weight loss, they were Overweight Preoccupation and Body Areas Satisfaction. Our study shows that different bulimic behaviors are variously conditioned by body image dimensions, some of which are predictors of behaviors that are risk factors for obesity and poor outcomes of bariatric treatment, whereas others increase the chance of pro-health behaviors among obese individuals.
Highlights
Obesity is a major health problem worldwide, as reflected by its steadily increasing prevalence in the adult population [1,2,3]
Given the validity of the body image construct and bulimic behavior, we thought it would be interesting to establish the predictive role of multidimensional body image in bulimic-type eating behavior among individuals scheduled for the surgical treatment of obesity
To contribute to the development of knowledge on the determinants of bulimic behavior and its relevance to the surgical treatment of obese patients, we focused on the determinants of these behaviors by analyzing multidimensional body image at the time of qualification for bariatric surgery
Summary
Obesity is a major health problem worldwide, as reflected by its steadily increasing prevalence in the adult population [1,2,3]. With the increasing prevalence of obesity, more radical forms of combating the problem are gaining recognition, such as bariatric surgery, which is currently the most effective and durable treatment for morbid obesity [10]. This type of surgery provides significant weight loss and helps treat over 40 obesityrelated conditions [11, 12]. It is important to identify variables with predictive value for the outcome of the surgical treatment of obesity [14]
