Objectives: Obesity is one of the most significant issues in global health due to its impact on health, socioeconomic burden. To better understand its etiology, this study investigated cross-sectional association between obesity and general characteristics (age, sex, income, education). Also, this study mainly focused on health related quality of life (HRQoL) and presence of depression as factors contributing to obesity.
Methods: This survey investigated Korean population (n=5,808) from the Korea National Health and Nutrition Examination Survey (2016). Chi-squared test, t-test, logistic regression analysis were used to explore the relationship between each characteristic and obesity. Multiple regression analysis was further undertaken to assess the relationship between depression and obesity.
Results: Age, sex, education, smoking, stress perception, depression and EuroQol-5 dimension (EQ-5D) were found to be associated with prevalence of obesity. The odd’s ratio (OR) of higher EQ-5D score group to obesity was 0.24 (95% confidence interval, 95% CI=0.13-0.44), and through multiple regression analysis, the adjusted OR of depression to obesity was 2.37. Additionally, there was a higher probability that obese individuals would perceive themselves as obese than non-obese individuals. And obese individuals were less likely to have weight-loss for 1year. Among weight control behaviors, intake restriction (OR=1.30, 95% CI=1.10-1.53) and fasting (OR=1.82, 95% CI=1.12-2.96) were associated with prevalence of obesity.
Conclusions: HRQoL and depression significantly affected to prevalence of obesity. These results suggest that HRQoL and mental health should be considered as important factors contributing to obesity.
