prevalence of hypertension and correlated risk factors among 25-64 aged inhabitants of tehran university of medical sciences population lab region

introduction: hypertension is the most important modifiable cardiovascular risk factor. hypertension is the leading global risk factor for mortality and as the third leading risk factor for cardiovascular disease burden. this survey has been conducted to determine the prevalence of hypertension among the inhabitants of 25-64 aged in 17th zone of tehran, selected as population lab region. methods: in a population-based cross-sectional survey conducted based on monica/who project, blood pressure measured with standard sphygmomanometer in sitting position after 10 minutes of resting in 1573 people. blood samples collected in venoject tubes for laboratory evaluation. analysis was performed using the more conservative threshold of sbp ≥ 160 mm hg and/or dbp≥ 95 mm hg according to the criteria of the world health organization (who). results: a total of 1573 persons (615 men and 958 women) were evaluated. hypertension prevalence (sbp≥160 or dbp≥95 or using antihypertensive drugs) was 29% in men and 34.8 in women. there was a significant correlation between systolic and diastolic blood pressure and bmi (p<0/0001). 58% of men and 55.8% of women with hypertension were obese (35>bmi>27).the mean of systolic and diastolic blood pressure had meaningful correlation with cholesterol, ldl, hdl, tg and homocysteine. conclusion: these results revealed that the prevalence of hypertension among this population was greater than supposed. the hypertension trend from 1992 is rising. obesity is one of the most important associated risk factors of hypertension. high prevalence of other cardiovascular risk factors is a matter of concern to this population.
