TI  - Eating behavior as a prognostic factor for weight loss after gastric bypass.
PG  - 445-51
AB  - BACKGROUND: Binge-eating disorder (BED) may be associated with unsatisfactory 
      weight loss in obese patients submitted to bariatric procedures. This study aims 
      to investigate whether the presence of binge eating before Roux-en-Y gastric 
      bypass (RYGBP) influences weight outcomes. METHODS: In a prospective design, 216 
      obese patients (37 males, 178 females, BMI=45.9 +/- 6.0 kg/m2) were assessed for 
      the lifetime prevalence of BED and classified at structured interview into 3 
      subgroups: no binge eating (NBE=43), sub-threshold binge eating (SBE=129), and 
      binge-eating disorder (BED=44). All patients were encouraged to take part in a 
      multidisciplinary program following surgery, and weight loss at follow-up was 
      used as the outcome variable. RESULTS: At 1-year follow-up, NBE patients (n=41) 
      showed percent excess BMI loss (%EBL) significantly higher than SBE patients 
      (n=112) (P=0.027), although this effect was not significantly different between 
      NBE and BED patients (n=44). At 2-year follow-up, NBE patients (n=33) showed %EBL 
      higher than SBE (n=64) (P=-0.003) and BED patients (n=34) (P<0.001). 
      Nevertheless, we found no significant weight loss differences between SBE 
      (subclinical) and BED (full criteria) patients at any period of follow-up. 
      Preliminary results at 3-year follow-up suggest that such an effect may be 
      enduring. CONCLUSION: The presence of a history of binge eating prior to 
      treatment is associated with poorer weight loss in obese patients submitted to 
      RYGBP. Because BED is highly prevalent in obese patients seeking bariatric 
      surgery, its early recognition and treatment may be of important clinical value.
