The occurrence of depressive symptoms in obese subjects starting treatment and not seeking treatment for obesity

Introduction The psychological profile of obese people deciding to start obesity treatment may be different from those not choosing to seek the therapy. Previous studies have shown a higher incidence of depression in obese than in normal weight people. However, data are lacking concerning the occurrence of depressive symptoms and their severity in obese subjects who do or do not decide to start treatment for obesity. Therefore, the aim of this study was to evaluate the prevalence and severity of depressive symptoms among obese people starting treatment and not seeking treatment for obesity. Materials and methods Enrolled subjects were 331 adults (241 women, 90 men), including 193 obese subjects starting treatment for obesity (46.8 +/- 13.2 years, BMI 37.6 +/- 5.5 kg/m(2)) and 138 obese volunteers never seeking treatment for obesity (44.3 +/- 12.5 years, BMI 34.7 +/- 4.3 kg/m(2)). Depression levels were determined using the Beck Depression Inventory (BDI). Results The level of depression was significantly higher among those starting treatment for obesity than those never seeking treatment for obesity (13.2 +/- 9.2 vs. 9.5 +/- 7.9 points; p < 0.001). This difference was statistically significant in women (14.4 +/- 9.2 and 11.0 +/- 8.2 points, respectively; p < 0.01), but not in men (7.2 +/- 6.4 and 7.3 +/- 7.1 points, respectively; p = 0.95). There were more women with moderate/severe depressive symptoms in the group starting treatment than in the group not seeking treatment for obesity (44.7 and 24.4%, respectively). No such difference was observed in men. Conclusions Obese subjects, especially women, with depressive symptoms are more likely to start treatment for obesity.
