PURPOSE: In recent years, there is no scientific epidemiological data about prevalence and risk factors of bronchial asthma among population in Mongolia. The aim of this study was to define some risk factors of bronchial asthma among urban adults.

METHODS: 1201 adults were randomly chosen aged over 20 years, who live in different districts of Ulaanbaatar city. The participants were interviewed using a questionnaire. The questionnaire was developed on the basis of WHO Protocol for Assessment of Prevalence of Major Respiratory Diseases and modified by local risk factor assessment and by other international survey approach including GINA, GOLD and ECRHS. Besides demographic data, information on smoking habits and atopic symptoms, anthropometrics were collected. Univariate and multivariate logistic regression modeling was performed to calculate odds ratio of various potential risk factors.

RESULTS: Of the respondents, 606 were males (50.5%) and 595 were females (49.5%). Asthma was more frequent in female than in male. The prevalence of wheezing and physician-diagnosed asthma was higher in overweight and obese than in normal weight. The BMI was higher in group with wheezing than in group without wheezing (p<0.01). 54% of subjects with bronchial asthma were smokers. 28.4% of subjects with allergic rhinitis has current asthma, while 11.6% of subjects without allergic rhinitis has asthma (P<0.01).

CONCLUSIONS: Female sex, advancing age, history of allergic rhinitis, tobacco smoking and body mass index were associated with significantly higher odds of having bronchial asthma.

CLINICAL IMPLICATIONS: Key words: Adults, bronchial asthma, BMI, risk factors, tobacco smoking
