Eating pathology before and after bariatric surgery: A prospective study

Abstract

Objective The objectives of the study were (1) to determine the prevalence of eating pathology in patients before bariatric surgery and at follow‐up; (2) to assess the relationship of presurgical eating pathology to various measures of psychopathology; and (3) to assess the relationship between presurgical eating pathology and outcome. Method One hundred sixteen patients were evaluated prior to surgery and at follow‐up an average of 5.5 years after surgery. Results Preoperative binge eating occurred in 52% of patients, 16% met criteria for binge eating disorder, and 10% had the night eating syndrome. All three forms of presurgical eating pathology were statistically associated with cognitive distortions. At follow‐up, 33% of patients were vomiting at least weekly. There was no relationship between presurgical eating pathology and weight outcome or presence of vomiting at follow‐up. Discussion Although postoperative vomiting usually does not represent purge behavior, it may represent failed attempts to binge. © 1999 by John Wiley & Sons, Inc. Int J Eat Disord 25: 293–300, 1999.

Explaining the role of binge eating behaviour in weight loss post bariatric surgery

“…In agreement with other studies assessing the effects of maladaptive eating behaviours on weight loss outcome, e.g. Bocchieri-Ricciardi et al, 2006;White, et al, 2006;Powers et al,1999), pre and postoperative BE were unable to significantly predict weight loss at three and six months postoperatively.…”

“…Some studies have found that higher preoperative levels of BE predicted poorer weight loss (e.g. Hsu, Sullivan, & Benotti, 1997), whereas others have found no evidence to support this (Bocchieri-Ricciardi et al, 2006;White, Masheb, Rothschild, Burke-Martindale, & Grilo, 2006;Powers, Perez, Boyd, & Rosemurgy, 1999) and some have even found better weight loss outcomes (e.g. Latner & Wilson, 2002).…”

“…Latner & Wilson, 2002). In addition, studies have reported that BE behaviours can continue or develop postoperatively affecting weight loss outcome (Hsu, Betancourt & Sullivan,1996;Scholtz, Bidlake, Morgan, Fiennes, El-Etar, & Lacey, 2007) whereas others report a decrease or disappearance following surgery (Powers et al, 1999;White et al, 2006;Colles, Dixon, & O'Brien, 2008). Such conflictions may be the result of methodological issues such as poor study design, measurement error or sampling errors due to problems with sample sizes or may indicate that the role of eating behaviours in individuals undergoing obesity surgery is more complex than first thought.…”

Does obesity surgery improve psychosocial functioning? A systematic review

“…Powers et al 66,80 published two studies both corresponding to EC IIb indicating a decrease in binge eating behavior during follow-up but an increase in vomiting. Higher rates of postsurgery vomiting were also reported by three other studies (one EC IIb, 78 two EC III 35,81 …”

Aspectos do acompanhamento psiquiátrico de pacientes obesos sob tratamento bariátrico: revisão

“…A presença de compulsão alimentar antes da intervenção cirúrgica, por exemplo, tem sido vista como fator de pior prognóstico, seja com relação à menor redução de peso [6][7][8] , seja com relação à reaquisição dele após a fase de estabilização, em geral devido ao equivalente "beliscar" compulsivo 3,[9][10][11][12][13] . Por outro lado, alguns estudos não encontraram associação consistente entre transtorno da compulsão alimentar periódica no pré-operatório e redução de peso após a cirurgia [14][15][16][17][18][19] . Tais discrepân-cias, em boa medida, se devem à ausência de conformidade entre os estudos com relação ao emprego de instrumentos de investigação 20 .…”
