Weight regain
Restrained eating at 36 months was significantly, positively related to 36mWR (β=1.10, p=0.025). Thus, more restrained eating at 36-month FU was related to higher weight regain. Emotional eating at 48-month FU was significantly, positively related to 48mWR (β=3.89, p=0.002); patients who reported more emotional eating 48 months after RYGB, regained more weight. None of the other Baecke and DEBQ scores at 15, 24, 36 and 48 months were related to 36 or 48 months weight regain.
Mixed model for physical activity
There was a significant, positive relationship between change in physical activity and %TWL. Looking at the specific follow-up moments, there was a significant, positive association between physical activity and %TWL at 15 months follow-up (β=0.22, p=0.012, Table 3). Patients who engaged in more physical activity at 15-months fol- low-up compared to baseline had higher weight loss. There was also a significant as- sociation at 36 months (β=0.39, p=0.002) and 48 months (β=0.62, p=0.005). Gender and age did not significantly influence the model; baseline Baecke score did and thus, the aforementioned models were adjusted for baseline score.
Mixed model for eating styles
For emotional eating there was a significant, negative association with %TWL at all follow-up moments, with the most prominent association at 48 months FU (β=-1.66, p=0.014, Table 3). Patients who experienced more emotional eating compared to baseline had less weight loss.
There was a negative association between external eating and %TWL. Patients who experienced more external eating had less weight loss, this association was only sig- nificant at 24 months FU (β=-1.06, p=0.003). For restrained eating there was also a negative association with %TWL; more restrained eating was associated with less weight loss. This association was significant at 15, 24 and 36-month follow-up, it was not significant at 48 months after surgery. In all eating style models baseline score of the specific eating style influenced the model, above results are thus adjusted for baseline score.
