Abstract: Objective To investigate health-related behavior and its affecting factors in adult patients with sleep breath disorder(SBD) and provide dangerous evidence for health management services. Methods 2 596 patients aged above 18 years in clinic were invited to our research from May 20011 to Dec 2013. Questionnaire included height, body weight, diet, physical exercise and health-related behavior factors. Multivariate stepwise logistic regression was used for statistics analysis. Results The effective responding rate was 86.5%. In adult patients with sleep breath disorder, the incidence of lack of physical exercise, obesity, smoking, drinking and diet high in salt and fat was in high proportion. In multivariate Logistic regression analysis, risk factors in lack of physical exercise were smoking and diet high in salt and fat, its protective factors were female, age and higher educational level (P<0.05). Risk factors of obesity were male, age, alcohol drinking and over-intake of salt and fat, and its protective factor was higher educational level (P<0.05). Risk factors of cigarette smoking were male, age, alcohol drinking, lack of physical exercise and over-intake of salt and fat, and its protective factors was higher educational level (P<0.05). Risk factors of alcohol drinking were male, age, overweight and obesity, smoking, and diet high of salt and fat (P<0.05). Risk factors of over-intake of salt and fat were obesity, smoking, drinking and lack of physical exercise, and its protective factor was higher educational level (P<0.05). Conclusion Health education and behavioral intervention should be offered to adult patients with sleep breath disorder.
