Association of Obesity with Depressive Symptomatology, Eating Habits, Interleukin-8 and Cortisol in a Young Population

Abstract

Obesity is the result of a complex combination of psychological, biological, and environmental factors. In this work, we evaluate whether obesity is related to eating habits, depressive symptomatology, as well as interleukin-8 and cortisol. A descriptive cross-sectional study was carried out in 232 university students. All youths were surveyed to determine their eating habits and depressive symptomatology. Anthropometric measures and a blood sample were taken to determine its biochemical profile and its concentration of interleukin-8 and cortisol. The results show that interleukin-8 increase in the overfat group. The altered eating behaviors were frequent in the studied group; they were associated with the presence of obesity and the variation of interleukin-8 and cortisol. Besides, we found correlations of interleukin-8 with age, glucose, and lipid profile in the overfat group. In conclusion, these results indicate that high adiposity is related to changes in the concentrations of interleukin-8 and eating habits, confirming that obesity is the consequence of a complex network of various factors.
