Popis: This study aimed to identify pre-treatment and immediate early treatment factors predicting continuous positive airway pressure (CPAP) use during the first week of therapy, when the pattern of non-adherence is established. Four domains of potential predictors were examined: pre-treatment demographic and clinical factors, patients' perceived self-efficacy, treatment delivery (mask leak and bothering side effects) and immediate disease reduction (residual respiratory events and flow limitation). The Autoset™ Clinical System objectively documented daily CPAP use, mask leak, residual respiratory events and flow limitation. Ninety-one CPAP-naive patients with newly diagnosed obstructive sleep apnea were followed for 1week after treatment initiation. Mean CPAP daily use during the first week was 3.4±2.7h, with significantly lower use observed in black than non-black participants (2.7 versus 4.4h, respectively, P=0.002). Less intimacy with partners caused by CPAP was the only treatment side effect correlated with CPAP use (r=-0.300, P=0.025). Reduced CPAP use during the first week was associated simultaneously with being black, higher residual apnea-hypopnea index and the treatment side effect of less intimacy with partners. The three factors together accounted for 25.4% of the variance in the CPAP use (R(2) =0.254, P
