Abstract: Objective To investigate snoring patients and high risk group of obstructive sleep apnea hypopnea syndrome (OSAHS) of Higher Vocational College students in Nanning and analyze the influencing factors, so as to provide reference for health guidance for snoring patients and high risk group of OSAHS.Methods We selected students of grade 2016 from Guangxi vocational and technical institute of health in Nanning by cluster sampling method.And an anonymous self-administered questionnaire were offered to them to collect data.Results There were 38 snoring patients (3.3%) and 23 high-risk people of OSAHS (2.0%) among1 161 respondents.The proportion of male, BMI, waist circumference, the proportions of smoker and drinker, sleeping position, nasal cavity and tonsil hypertrophy in snoring group were higher than in non-snoring group (χ2/t = 13.70, 2.46, 14.20, 28.60, 20.80, P<0.05).Logistic regression analysis indicated that the regression coefficient B of the snoring influencing factors were positive, such as waits circumference, history of drinking, history of stenosis of the nasal cavity and history of tonsillar hypertrophy.Among the OSAHS influencing factors, the regression coefficient B of the frequency of snoring and scores of Epworth sleep scale were positive and that of the pillow height was negative (P<0.05).Conclusion Reduction of waist circumference, abstinence and treatment of tonsillar hypertrophy and the diseases that causes narrowing of the nasal cavity would reduce the risk of soring disease.Reducing snoring frequency, improvement of somnolence symptoms and a right pillow would reduce the risk of OSAHS.
