ABSTRACT

<p><b>OBJECTIVE</b>To investigate how smoking was affecting the prevalence of sleep apnea/ hypopnea syndrome (SAHS) among adults aged over 30 years in Chengde city of Hebei province.</p><p><b>METHODS</b>1168 subjects, over 30 years of age were derived from a random sample from a community-based population in Shuangqiao district of Chengde city. All subjects responded to a questionnaire at their own houses regarding their habits of snoring and smoking. 1168 subjects (95.2%) answered the questions satisfactorily.</p><p><b>RESULTS</b>(1) Among the smoking groups, the prevalence of snoring was 69.09%, higher than that in the nonsmoking groups 45.07% (P = 0.000). (2) In males, the smoking group had a higher prevalence (69.72%) of snoring than in the nonsmoking group (60.80%, P = 0.033). (3) Females in the smoking group had a higher prevalence of snoring (61.80%) than in the nonsmoking group (39.70%, P = 0.011). (4) The prevalence of snoring in males (60.80%) was significantly higher than that in females (39.70%, P = 0.000). (5) The prevalence (69.72%) of snoring in smoking males was similar to that in smoking females (61.80%, P = 0.336). (6) Data from logistic regression analysis indicated that smoking was one of the factors affecting snoring. (7) According to the degree of snoring, 127 moderate and severe snorers were measured by portable PSG for a whole night and the prevalence of SAHS was estimated. According to the AHI > or = 5 and the ESS > or = 9 cutoff-points, the prevalence rates of SAHS in smoking groups were both significantly higher than that in nonsmoking groups (P < 0.001).</p><p><b>CONCLUSION</b>Smoking and snoring among adults aged over 30 years had correlation in our city.</p>
