ABSTRACT
OBJECTIVE: To investigate the incidence and risk factors of snoring in Boertala Mongolia Autonomous Prefecture of Xinjiang. METHODS: A random sample of 4444 people, aged > or = 30, from Mongolian, Kazakh, Uygur, and Han population in Boertala Mongolia Autonomous Prefecture was investigated for the presence of snoring and the risk factors. RESULTS: The incidence of snoring was 21.8% (n = 967) in this sample population. The incidences of snoring adjusted by age and gender were 30.3%, 16.4%, 23.5%, and 19.5%, respectively in Mongolian, Kazakh, Uygur, and Han populations. The ratios of smoking and alcohol consumption were higher in subjects of snoring (43.4% vs 27.8%, and 40.5% vs 24.2%, respectively). Multiple unconditional logistic regression analysis showed that body mass index (BMI) was the major risk factor for snoring. Neck circumference was significantly correlated with snoring in Kazakh and Mongolian, populations. Alcohol consumption was a risk factor for snoring in Mongolian, Kazakh, and Han populations. CONCLUSION: The prevalence of snoring is high in Boertala Mongolia Autonomous Prefecture of Xinjiang, especially in the Mongolian population. BMI, neck circumference and alcohol consumption were risk factors for snoring.
