The data was analysed by means of stratification and standardization methods. \ Results\ The standardized prevalence rate of hypertension （26.2%） for smokers\|alcohol drinkers was significantly higher than that （17.7%） for smokers\|nondrinkers. The standardized prevalence rate （26.8%） for nonsmokers\|drinkers was significantly higher than that （18.7%） for nonsmokers\|nondrinkers. There was no significant differences in the standardized prevalence rate between smokers\|drinkers and nonsmokers\|drinkers, there was also no significant difference between smokers\|nondrinkers and nonsmokers\|nondrinkers. \ Conclusion\ Alcohol intake is a risk factor of hypertension, but smoking cigarette did not increase the prevance rate of hypertension in Mongolian people.
