Figure 1: Two-mediator model of the relationship between percentage of total weight loss (%TWL) and depressive symptoms.
%TWL indirectly effects depressive symptoms ( c’) via appearance evaluation and body area satisfaction. The specific indirect effect through appearance evaluation is a1+b1 and through body area satisfaction a2+ b2.

RESULTS
Study population
There were no significant differences between the included (n=590) and excluded (n=744) patients with regards to age, follow-up time since bariatric surgery, baseline BMI and BMI at 12 and 24 months after bariatric surgery. There were significantly more females in the included population: 81.2% compared to 75.3% (p=0.01). Mean age of the included patients was 47.7 years. Before bariatric surgery, the mean BMI was 45.4 kg/m2. Most patients had undergone a RYGB (n=511, 86.9%), 66 patients (11.2%) had undergone a gastric sleeve and 11 patients (1.9%) had undergone lap- aroscopic adjustable banding. Mean BMI was 31.8 kg/m2 at 12 months follow-up and 31.1 kg/m2 at 24-month follow-up. At the time of the current survey the mean follow-up was 32 months, BMI was 30.7 kg/m2 and TWL was 32.1%.
Patient characteristics
A total of 65 patients (11.0%) had undergone BCS (BCS-group). There was a desire for BCS in 368 patients (62.4%, D-group), and no desire for BCS in 26.6% of the pa- tients (n=157, ND-group).
The ND-group contained the lowest rate of females (68.2%, p<0.001), compared to the D-group (84.5%) and the BCS-group (93.8%) (Table 2). Age, follow-up time and type of bariatric procedure were not significantly different between the three groups.
BMI before bariatric surgery was 46.2 kg/m2 in the D-group, which was significantly higher compared to the ND-group (mean: 44.1 kg/m2, p=0.001) and the BCS-group (mean: 43.9 kg/m2, p=0.011). Patients who underwent BCS had the lowest BMI at all
