Methods Residents ( o-ver 4 years old ) were selected using disproportionate random cluster sampling and surveyed by uniform questionnaire. The prevalence of asthma was calculated and gender difference was compared. Risk factors of asthma were evaluated using univariate analysis. Results The overall prevalence of asthma in Jinzhou city was 1. 2% ( 48/4 000 ), increased compared with 0. 71% in 1999. The prevalence of asthma was 1. 373% in male and 1. 033%in female, and the difference was not statistically significant ( P >0. 05 ) Among the 48 asthma patients, 20 patients BMI > 24 kg/m2 ( OR = 1. 838 , P <0. 05 ), 35 were smoking ( OR = 2. 324, P < 0. 01 ), 15 had been breastfed ( OR = 0. 432, P < 0. 01 ), 39 had childhood history of asthma - related diseases ( OR = 2. 428, P <0. 01 ), 36 had hereditary disposition ( OR = 2. 592, P < 0. 01 ), 33 were raising pets ( OR = 2. 386, P < 0. 01 ), 32 had asthma - related illnesses ( OR = 2. 104, P < 0. 01 ), 25 had allergen - induced asthma ( OR = 2. 072, P < 0. 01 ) .
