Abstract: | Background Long-term outcomes of gastric banding regarding depression and predictors of change in depression are still unclear. This
prospective, controlled study investigated depression and self-acceptance in morbidly obese patients before and after gastric
banding.
Methods A total of 248 morbidly obese patients (mean body mass index BMI] = 46.4, SD = 6.9) seeking gastric banding completed questionnaires
for symptoms of depression (Beck Depression Inventory) and self-acceptance. One hundred twenty-eight patients were treated
with gastric banding and 120 patients were not. After 5 to 7 years, patients who either had (n = 40) or had not (n = 42) received gastric banding were reassessed.
Results In the preoperative assessment, 35% of all obese patients suffered from clinically relevant depressive symptoms (BDI score
≥18). The mean depression score was higher and the mean self-acceptance score was lower than those of the normal population.
Higher preoperative depression scores were observed among patients living alone and who had obtained low levels of education.
After 5 to 7 years, patients with gastric banding had lost significantly more weight than patients without gastric banding
(mean BMI loss 10.0 vs. 3.3). Gastric banding patients improved significantly in depression and self-acceptance, whereas no
change was found in patients without gastric banding. Symptoms of depression were more reduced in patients who lost more weight,
lived together with a partner, and had a high preoperative depression score.
Conclusion Morbid obesity is associated with depressive symptoms and low self-acceptance. Gastric banding results in both long-term weight
loss and improvement in depression and self-acceptance. |
