Liao Y, et al. - Researchers assessed cigarette smokers and nonsmokers in the general population of central China regarding their sleep quality and sleep disturbances. A total of 26,282 subjects completed self-reports detailing cigarette smoking characteristics. The investigators defined cigarette smoker as having smoked ≥ 100 cigarettes in a lifetime and smoked during the last 28 days. Poor sleep quality and sleep disturbances were reported by significantly more smokers than nonsmokers. As per linear regression analyses, poor sleep among smokers had an inverse correlation with cigarettes per day and had a positive correlation with years of smoking, quit attempts, and smoking craving. They recommend educating smokers about the link between cigarette smoking and poor sleep quality, and advising them that improvement of sleep quality could be gained as one of several important health benefits from smoking cessation. Recommendation for sleep therapy as an adjunctive treatment for smoking cessation was thus made.
