The risk of obstructive sleep apnea is highly correlated with depressive symptoms among the Korean adults population: results from the 2020 Korea National Health and Nutrition Examination Survey

Abstract

Abstract Objectives We aimed to examine the association between Obstructive Sleep Apnea (OSA) risk, health behaviors, and depressive symptoms in a representative Korean sample. Methods Cross-sectional data from the 2020 Korea National Health and Nutrition Examination Survey (KNHANES) were analyzed. The sample included 4,352 adults aged 40 years and older. Multiple linear regression analysis was performed to examine the association between OSA risk, health behaviors, and depressive symptoms. Results In total, 23.1% of the participants reported a high risk of OSA. Of the respondents, 39.8%, 19.0%, 27.2%, and 8.7% reported hypertension, snoring, tiredness, and observed apnea, respectively. The prevalence of moderate-severe depressive symptoms among adults with high-risk OSA was 7.5%. The significant associations between OSA risk and sex with PHQ-9 were shown in univariate linear regression. In the multiple linear regression analysis, the association between high risk of OSA and PHQ-9 showed in total (B = 1.58; P < 0.001), male (B = 1.21; P < 0.001), and female (B = 1.93; P < 0.001). Conclusions A high risk of OSA was associated with an increased prevalence of depressive symptoms. Monitoring the risk factors of depressive symptoms, including OSA, or unhealthy behaviors may decrease the mental health issues of middle-aged and older adults.
