Abstract

Objective: It is known that depression is common in obese individuals. Besides the effects of obesity, pathogenic effects of increase in visceral and abdominal fat mass on depression are also being investigated. Our study aimed to show the relationship between visceral fat percentage detected with practical methods and the presence and severity of depression.

 

Materials and Methods: Our study included 104 obese patients and 50 healthy controls. In all individuals, the severity of depression was assessed using the Beck Depression Inventory (BDI). Anthropometric measurements, visceral fat percentage, and body fat percentage were measured using the bioelectric impedance method.

 

Results: The mean age was 51.5±12.3 years, and 65 participants (62.5%) were women. BDI scores were statistically higher in the obese group than in the control group (23.1±10.9 and 12.1±9.4, p<0.001). In the obese group, 63.5% of patients were depressed, and in the control group, this was 24%. Women were more depressed in the obese group, but there was no significant difference between men and women in the control group. Body fat percentage was the highest correlating parameter with depression severity. Positive correlation was found between depression severity and body mass index, waist circumference, hip circumference, and visceral fat percentage. In the logistic regression analysis, obesity was found as an independent risk factor for depression (OR: 4.84, 2.1-10.7, p<0.001).

 

Conclusion: According to the results of our study, obesity is a significant and independent risk factor for depression. Obesity type and body composition are important factors that determine the severity of depression.
