Tabaquismo activo y pasivo asociados a calidad del sueño en universitarios

Introduction: The inhalation of tobacco smoke, regardless of whether individuals smoke or are exposed to it, has a considerable effect on sleep quality. Objective: To establish the association between active and passive smoking with sleep quality among university students. Methods: Cross-sectional analytical study. The Pittsburgh Sleep Quality Index was applied to assess sleep quality. Smoking habits were evaluated through active smoking and passive smoking at home or work, in a sample of 2495 students. A generalized linear model of the Poisson family with robust variance was used to determine the crude prevalence ratio (cPR) and adjusted prevalence ratio (aPR). Each measure of association has been presented with its 95 % confidence interval (95% CI). Results: The prevalence of active smokers was 12.26%, and of passive smokers, 16.67%. The multivariable analysis found that active smokers were 2.23 times more likely to have poor sleep quality (PR: 2.23; 95% CI 1.89–2.61). Passive smokers were 1.74 times more likely to have poor sleep quality (PR: 1.74; 95% CI 1.48–2.03). Conclusions: Tobacco smoke, whether inhaled directly by smokers or indirectly by passive smokers, is associated with the sleep quality of university students.
