DISCUSSION
The goal of this systematic review and meta-analysis is to give an overview of behav- ioral and psychopathology related moderators of weight loss after RYGB. The results show that compliance to follow up and taking part in physical activity are associated with more weight loss after surgery. Psychopathology related issues were however not associated with less weight loss.
The importance of compliance to follow-up has been well established in laparoscopic adjustable gastric band (LAGB) patients. In one study more than half of the patients lost to follow up had an EWL < 25% 1,80. The effect by which compliance to follow-up leads to more weight loss in these patients has been attributed to adjustment of the band 1. For RYGB is it assumed that the effect of compliance to follow-up is less. However, a previous meta-analysis with four studies also showed a positive effect of compliance to follow-up in RYGB patients 17. In six studies included in this meta-anal- ysis %EWL was higher in compliant patients on each of the follow up moments, this
