to the intention to eat less. For all subscales, total scores can be calculated. These scores range from 1 to 5; a higher score means the patient indicates being a more emotional, external and/or restrained eater. For the DEBQ score, a maximum change score was also calculated using baseline and 15 or 24 months follow-up scores: ΔEME for change in emotional eating; ΔEXE for change in external eating and ΔREE for change in restrained eating.
Weight change
Body weight was assessed preoperatively (baseline) and at 12, 15, 24, 36 and 48 months after surgery; height was assessed during preoperative screening. Weight loss was calculated and reported as stated in the most recent guidelines: Body Mass Index (BMI in kg/m2) and percent total weight loss (%TWL) 24. New variables were created for maximum weight loss and weight regain, since up to date, there are no uniform definitions to report this 3,25. First, nadir boy weight was defined as the lowest weight up to 24 months post-surgery. Based on that, maximum postoperative weight loss (TWLmax) was calculated using the following formula:
TWLmax =
baseline body weight - nadir body weight baseline body weight
Since weight regain usually develops after the weight plateau, weight regain (WR) was calculated for 36 and 48 months follow-up with the following formulas:
36mWR =
48mWR =
36-month body weight - nadir body weight nadir body weight
48-month body weight - nadir body weight nadir body weight
