| Abstract: Objective To understand the epidemiological situation and susceptibility factors of bronchial asthma (asthma) in Guiyang. Methods The uniform epidemiological survey form was adopted to conduct sampling survey by district and neighborhood committee by random, stratified, unequal ratio and cluster sampling method. Univariate χ2 analysis and multivariate logistic regression analysis were used to screen the related risk factors of asthma. Results A total of 5,900 permanent residents over the age of 18 were actually surveyed throughout the region, including 2,917 males and 2,983 females, were investigated in the whole region. There were 164 patients with asthma, 79 males and 85 females, with a total prevalence of 2.78% in females and 2.71% in males. There was no significant difference between male and female (P <0.05)，but the prevalence gradually increased with the increase of age. Age, family history of asthma, smoking, passive smoking, childhood respiratory infections, allergic rhinitis, pollen allergies, drug allergies and food allergies were the risk factors for asthma. Among them, family history of asthma（OR=13.713 , P＜0.05）, childhood respiratory infections （OR=4.088 , P＜0.05）and pollen allergies（OR=3.587 , P＜0.05） were independent risk factors for asthma. Conclusions This survey basically represents the prevalence of asthma among adults in Guiyang. It is necessary to improve adults' awareness of risk factors of asthma, strengthen the prevention and control of risk factors, and prevent and reduce the occurrence of asthma. |
