Continuous positive airway pressure (CPAP) is the treatment of choice for obstructive sleep apnea (OSA). However, compliance with CPAP varies from study to study, and studies on predictors of compliance with CPAP are insufficient in Korea. The aim of this study was to identify factors predicting compliance with CPAP therapy in patients with OSA. We retrospectively reviewed medical records, polysomnography (PSG) records, and self-report questionnaires of patients with OSA. Criteria for compliance was the use of CPAP devices for ≥ 4 h per night for ≥ 70% of the consecutive 30 nights (i.e., 21 days) during the first 3 months of treatment initiation. The patients were classified into two groups: compliant and non-compliant. Logistic regression analyses were performed to identify clinical factors and PSG parameters associated with compliance with CPAP. Among 188 participants, 80 were classified into the compliant group and 108 were classified into the non-compliant group. The ratio of stage N1 (P = 0.011) and health insurance coverage (P = 0.007) were significantly associated with compliance with CPAP, with an explanatory power of 18.6% (R2 = 0.186, P < 0.001). This study indicated that the stage N1 ratio and health insurance coverage were significant predictors of CPAP compliance. It is necessary to confirm whether the relationship between a high stage N1 ratio and compliance is reproduced in a larger sample and in individuals from other countries. |
