Results
In this study 12494 subjects had a work-up, 48% were males, thirty-five in Isfahan, 50.1% in Arak and 14.9% in Najafabad. The mean age of men and women were 38.99±15.30 year and 38.80±14.54 year respectively.The prevalence of high BP in men and women was 15.6% and 18.8% respectively.The prevalence of high BP was higher in women than in men, except in the younger age classes.Overall 26.7% of hypertensive men and 47.7% of hypertensive women were on anti-hypertensive pharmacological treatment. Among the treated patients, BP was normalized in 6.4% of the men and 13.8% of the women.In 84.6% of men with high BP and 81.3% of women with high BP, at least one other cardiovascular risk factor was present and its prevalence increased with age in both genders. Obesity was the most frequent associated risk factor. Except for smoking, the prevalence of each cardiovascular risk factor increased with the severity of hypertension, except in young women.
Conclusion
Rate of high BP, even in treated subjects, is high. Many subjects with high BP have at least one other association cardiovascular risk factors.
