Psychological characteristics, eating behavior, and quality of life assessment of obese patients undergoing weight loss interventions

Abstract

Background and Aims: Bariatric surgery is the most effective treatment for obesity. however, not all patients have similar weight loss following surgery and many researchers have attributed this to different pre-operative psychological, eating behavior, or quality-of-life factors. the aim of this study was to determine whether there are any differences in these factors between patients electing to have bariatric surgery compared to less invasive nonsurgical weight loss treatments, between patients choosing a particular bariatric surgery procedure, and to identify whether these factors predict weight loss after bariatric surgery.Material and Methods: this was a prospective study of 90 patients undergoing gastric bypass, vertical sleeve gastrectomy, or adjustable gastric banding and 36 patients undergoing pharmacotherapy or lifestyle interventions. all patients completed seven multi-factorial psychological, eating behavior, and quality-of-life questionnaires prior to choosing their weight loss treatment. Questionnaire scores, baseline body mass index, and percent weight loss at 1 year after surgical interventions were recorded.Results and Conclusions: surgical patients were younger, had a higher body mass index, and obesity had a higher impact on their quality of life than on non-surgical patients, but they did not differ in the majority of eating behavior and psychological parameters studied.

Suboptimal Weight Loss and Weight Regain after Gastric Bypass Surgery—Postoperative Status of Energy Intake, Eating Behavior, Physical Activity, and Psychometrics

“…Previous studies have shown inconclusive results and, unlike the present study, tend to present only preoperative scores [12, 17, 43]. Lower disinhibition and hunger scores (TFEQ) have been reported 1 year after adjustable gastric banding or vertical banded gastroplasty on those successful in weight loss (versus unsuccessful) [44].…”

“…Overconsumption of energy-dense food postoperatively has also been associated with WR [14]. Eating behavior (including restrained, disinhibited, external, and emotional eating, and hunger perception) have shown to improve after GB [15, 16], and some studies suggest that preoperative scores may predict weight loss outcomes [12, 17]. Additionally, health-related QoL improves in most patients after bariatric surgery, but poor weight loss outcome, along with postoperative depression, can influence QoL negatively [18, 19].…”

Patient‐reported quality of life in a randomized placebo‐controlled trial of naltrexone/bupropion for obesity

“…Other variables not assessed in this study could have played a role in quality of life improvements, such as physical activity or type of diet . Furthermore, we cannot generalize these results beyond the clinical trial setting, as differences in quality of life have been observed in varying subgroups of persons with obesity .…”

Using Lifestyle Medicine in U.S. Health Care to Treat Obesity

“…A 2008 meta-analysis found that 64% of patients who underwent BSx had weight regain within 48 months (29). Many researchers have attributed this large variability in weight loss to different preoperative psychological, eating behavior, or quality-of-life factors (33). Indeed, Miras et al (33) found that weight loss after BSx in 90 patients was predicted by preoperative scores of dietary restraint, disinhibition, and presurgery energy levels.…”

Coleman and Brookey (14) found that percent excess weight loss 1 year after RYGB was related to greater diet soda intake and percentage of initial weight lost was related to greater water intake, independent of presurgery health status and lifestyle behaviors.…”
