Association between health-related behaviors and obstructive sleep apnea among Korean adults.

We aimed to investigate the association between health-related behaviors and obstructive sleep apnea (OSA) among Korean adults. A cross-sectional design using national open data was employed. Data from 8,096 adults aged 40 years and above who participated in the Korea National Health and Nutrition Examination Survey between 2019 and 2021 were analyzed. The participants' OSA risk level was assessed using the STOP-Bang questionnaire. A logistic regression analysis was performed to investigate the association between health-related behaviors and high risk for OSA. The association between health-related behaviors and OSA risk remained significant for former smokers (OR = 1.643) and high-risk drinking (OR = 1.365), after adjusting for variables that showed significant differences in general and metabolic characteristics. Implementing lifestyle modifications is crucial for mitigating the health and societal impact of OSA. Understanding and addressing modifiable risk factors, including high-risk drinking and smoking, should be prioritized in nursing intervention. Nursing interventions are critical for preventing and managing OSA among Korean adults. Prioritizing high-risk behaviors through cessation programs and education is essential. Vulnerability of individuals living alone must be addressed through community outreach and support services. Emphasizing routine screenings for pre-hypertension and pre-diabetes, promoting balanced nutrition, and encouraging physical activity are crucial.
