Body weight
Body weight measurements before bariatric surgery and 12, 24, and 36 months after were retrieved from the database. BMI, percentage excess weight loss (%EWL) and percentage total weight loss (%TWL) were calculated 21. Stability of weight was de- fined as current weight +/- 5% in the last 12 months, compared to the weight in the existing database. Subsequently, it was assessed whether a patient met the weight qualifications for reimbursement in the Netherlands (i.e., stable weight for ≥12 months and BMI < 35 kg/m2).
Statistical analyses
Descriptive statistics were calculated to summarize baseline characteristics. For fur- ther analysis, patients were divided into three groups: the BCS-group, consisting of patients who already had BCS; the desire-group, consisting of patients with a desire for BCS and the no desire-group, consisting of patients without a desire for BCS. Differences between these groups were calculated using ANOVAs for continuous variables and Chi-square tests for discrete variables. For ANOVAs post hoc anal- ysis were performed when there were significant differences. Pearson’s correlation was calculated to study the relationship between body satisfaction and PRS grading. Findings were considered statistically significant when p was <0.05. All analyses were performed using SPSS software version 23.
RESULTS
Study population
Of the included population (n=590), 81.2% was female. Mean age was 47.7 years. Education was low in 39.5% (n=232), medium in 40.7% (n=240) and high in 19.7% (n=116). Most patients had a part-time or full-time job (n=369, 62,5%). Income was €20,070 or lower in 108 patients (18.3%), between €20,070 and €34,085 in 132 pa- tients (22.4%), between €34,085 and €43,602 in 12.9% (n=76) and €43,602 or higher in 14.9% (n=88). A total of 31.5% of the patients did not want to disclose their income. Most patients had undergone Roux-en-Y gastric bypass (n=511, 86.7%) and mean follow-up was 32 months (range 26-39 months). Mean current BMI was 30.7 kg/m2; this was 45.4 kg/m2 before bariatric surgery. Mean TWL was 32.1% and mean EWL was 74.5%.
Patient characteristics
The majority of patients desired BCS (n=368; 62.4%), while 26.6% (n=157) did not desire BCS and 11.0% (n=65) already had undergone BCS. In the BCS-group, 93.8% was female; this was higher than in the desire-group (84.5%) and the no desire-group (68.2%) (p<0.001, Table 1). Patients without a desire (49.8 yrs.) were significantly old- er compared to the BCS-group (45.1 yrs., p=0.008) and the desire-group (47.2 yrs.,
