Is food addiction a predictor of treatment outcome among patients with eating disorder?

ObjectivesThe study aimed to examine whether food addiction (FA) was associated with greater severity in both binge eating disorders (BED) and bulimia nervosa and, therefore, to determine if FA was predictive of treatment outcome.MethodSeventy-one adult patients with bulimia nervosa and BED (42 and 29, respectively) participated in the study. FA was assessed by means of the Yale Food Addiction Scale.ResultsThe results confirmed a high prevalence of FA in patients with binge disorders (around 87%) and also its association with a greater severity of the disorder (i.e., related to an increased eating psychopathology and greater frequency of binge eating episodes). Although FA did not appear as a predictor of treatment outcome in general terms, when the diagnostic subtypes were considered separately, FA was associated with poor prognosis in the BED group. In this vein, FA appeared as a mediator in the relationship between ED severity and treatment outcome.DiscussionsOur findings suggest that FA may act as an indicator of ED severity, and it would be a predictor of treatment outcome in BED but not in BN.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/152018/1/erv2705.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/152018/2/erv2705_am.pd

Racial Differences in Psychological Symptoms and Eating Behaviors Among Bariatric Surgery Candidates

BACKGROUND: Black patients typically lose less weight than White patients following bariatric surgery; however, the reasons for this racial disparity are unclear. The purpose of the current study was to evaluate whether there are differences in psychiatric symptoms and problematic eating behaviors between White and Black patients pursuing bariatric surgery as this may aid in understanding postsurgical weight loss disparities and inform psychosocial assessment of bariatric candidates. METHODS: A retrospective chart review was conducted of participants (N = 284) who completed a psychological evaluation prior to surgery. Information collected included history of binge eating and purging as well as data from measures administered (i.e., the Hospital Anxiety and Depression Scale, the Emotional Eating Scale, and the Yale Food Addiction Scale 2.0). RESULTS: White patients reported higher levels of eating in response to anger/frustration (p = .03) and eating in response to depression (p = .01) than Black patients. White patients also reported more symptoms of food addiction, a difference that was trending toward significance (p = .05). No significant differences were found on measures of anxiety or depression. CONCLUSION: White patients appear to have higher levels of presurgical problematic eating as compared with Black patients pursuing bariatric surgery; thus, these measurements of problematic eating may not explain the racial disparity in outcomes. However, future research should determine whether measures are valid among diverse populations and identify additional factors that may contribute to racial disparities in bariatric outcomes
