The presence snoring breathing during (DBS) also reported. Logistic regression yielded adjusted odds ratios (ORs) for each disorder by status. Results Compared with never smokers, ORs (95% CI) insomnia were 1.39 (1.25–1.54) experimenters (smoked once or few times) 0.91 (0.83–1.00) current smokers. corresponding 1.42 (1.16–1.74) 3.58 (3.15–4.06) ( P trend =0.003), but more likely to report DMS (OR=1.45, 95% CI=1.28–1.63, Conclusions terms dosage, associated DBS, increasing from smokers experimental Current positively DMS, negatively DIS EMA.
