Introduction: In recent years, there is no scientific epidemiological data about prevalence and risk factors of bronchial asthma among population in Mongolia. Goal: The aim of this study was to define some risk factors of bronchial asthma among urban adults. Materials and Methods: 1201 adults were randomly chosen aged over 20 years who lives in different districts of Ulaanbaatar city. The participants were interviewed using a modified questionnaire of “Global Initiative for Asthma” - GINA. Besides demographic data, information on smoking habits and atopic symptoms was collected. Univariate and multivariate logistic regression modeling was performed to calculate odds ratio of various potential risk factors. The lung function of subjects was checked using a spirometry Easyone, calculating the indexes Forced expiratory volume 1sec (FEV1), forced vital capacity (FVC), FEV1/FVC ratio. 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. The mean value for FEV1 was 2.86±0.85 L and FVC was 3.60±0.94 L in overall and the lung function was lower in smokers than in non-smokers with bronchial asthma. 28.4% of subjects with allergic rhinitis has current asthma, while 11.6% of subjects without allergic rhinitis has asthma (p<0.01). Conclusion: Female sex, advancing age, history of allergic rhinitis, tobacco smoking and body mass index were associated with significantly higher odds of having asthma.

Introduction: According to World Health Organization, air pollution is a major environmental risk to health and is estimated to cause approximately 1.6 million premature deaths worldwide per year. The air pollution of Ulaanbaatar city is rising year after year.Goal: The aim of this study was to define the lung function of adults in Ulaanbaatar.Materials and Methods: 1196 adults were randomly chosen aged over 20 years of Ulaanbaatar city. Of them 238 subjects were excluded because they had at least one of the following: a history of lung diseases including asthma, COPD, pulmonary tuberculosis, lung fibrosis; symptoms of chronic cough, wheeze, or dyspnea; history of thoracic surgery; history of major acute illness in the past 3 months; or a history of respiratory tract infection in the past 4 weeks. Besides demographic data, information on smoking habits was collected. The lung ventilation function of subjects was checked using a spirometry EasyOne, calculating the indexes Forced expiratory volume 1sec (FEV1), forced vital capacity (FVC), FEV1/FVC ratio. Lung function measurements followed a standardized protocol and fulfilled the ATS criteria.Results: Of the respondents, 486 were males (50.7%) and 472 were females (49.3%). There was a negative correlation between each lung function and age (p<0.05). The lung function was significantly lower in female than in male, for FEV1, FVC (male - FEV1 3.66±0.659 L, FVC 4.467±0.716 L, female-FEV1 2.663+0.559 L, FVC 3.237+0.586 L). In overall, FVC, FEV1 was decreased by 34.5, 37.2 percent, respectively compared with European LLN value.Conclusion: The mean value for FEV1, FVC, FEV1/FVC ratio was 3.17±0.78 L, 3.86+0.89 L and 82.02±6.75 % in overall, respectively.

BACKGROUND: According to the United Nations, drug reports 2016, 250 million people aged 15 to 64 an estimated 29 million of them have used drugs and narcotics. The United nations states that the drug and narcotic manufacturing have increased by three times in east 15 years. Mongolia is located between Russia and China that are the most drug used countries in the world and it can increase the risk of drug usage in Mongolia. OBJECTIVE: Study to knowledge and attitude about drugs and narcotics among the high school, college and universities students in Ulaanbaatar. METHODS: The research was conducted among the school, college and universities students and the analytic research method was used in our research. 176 middle and high school students, 215 university students and 70 college students from morning classes were participated in the survey. The survey research was used method of collecting information and materials about the drug usage and narcotics. SPSS 17 was used for statistical analysis. RESULTS: The highest point was 16 (n=1) and lowest point was 0 (n=16) and the knowledge of drugs among the students was 8.14. Results releated that 7.8% (n=36) of students have enough information about the drugs and narcotics, 62.9% (n=261) of students did not have enough information and 29.3% (n=135) of them have informed moderately. CONCLUSIONS: Exploring the knowledge about drugs and narcotics among the students, 7.8% of them have enough information, 62.9% of them did not have enough information and 29.3% of them have informed moderately
