SB was assessed using (1) self\u2010reported SB, based on participants' self\u2010report; (2) PSG\u2010based SB, based on polysomnographic findings; and (3) a combined definition requiring positive self\u2010report and PSG. QoL was assessed using the WHOQOL\u2010Bref scale. Sociodemographic, behavioural, psychosocial, and clinical variables were considered as confounders. The association between SB and QoL (rate of QoL, satisfaction with health and overall), as well as its specific domains (physical health, psychological, social relationships, and environment), was analysed using adjusted Poisson regression models. Results were presented in Rate Ratio (RR) and 95% confidence interval (95% CI).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The mean score for the rate of QoL question was 16.6\u2009\u00b1\u20095.1, whereas satisfaction with health had a mean score of 15.4\u2009\u00b1\u20096.3. The overall WHOQOL\u2010Bref score was 14.2\u2009\u00b1\u20093.0. In the adjusted analysis, individuals who self\u2010reported SB had lower satisfaction with their health (RR 0.93; 95% CI 0.88\u20130.98) and lower QoL levels in the social relationships' domain (RR 0.95; 95% CI 0.92\u20130.99).
