Abstract

Background: Obesity is one of the public health problems in South Korea. It has been known that various physical and psychological diseases, such as depression, are associated with obesity. Some studies have found that subjects with obesity, who had higher rates of depression, exhibited more weight change. Therefore, we evaluated relationship between weight change and depression in a representative sample of the Korean population.
Methods: We analyzed the data of 17,813 participants (7,550 men and 10,263 women) from the 2010 to 2012 Korea National Health Survey. Depression was estimated based on cases of depression that had been diagnosed by a physician. Multivariate logistic regression analyses were performed to examine the relationship between weight change and depression.
Results: The weight gained during the past 1 year increased the risk of depression (odds ratio [OR]=1.566, 95% confidence interval [Cl]=1.218?2.013, P=0.002). This association was statistically significant among women (OR=1.603, 95% CI=1.210?2.122). Compared to the obesity group (body mass index ≥25), the non-obesity group had a higher adjusted OR for depression (OR=1.670, 95% CI=1.195?2.334). Those aged 40 to 60 years (OR=1.797, 95% CI=1.284?2.515) and over 60 years (OR=1.889, 95% CI=1.003?3.557) had higher ORs for depression, while those aged under 40 years showed no significant differences.
Conclusion: Weight gain in the past 1 year is associated with depression, especially in subjects who are female, non-obese, and aged over 40 years. Further research using a prospective design is needed to investigate the interaction between weight change and depression.
