Abstract

This study was done to estimate the prevalence of high blood pressure (BP) in treated and non-treated subjects with respect to age and gender and its association with other cardiovascular risk factors in Iran. This cross sectional study was performed in three cities of Iran on participants over 19 years at 2002. First a questionnaire consisting of demographic details, drug intake and smoking status was filled. Then physical examination including systolic and diastolic blood pressure (SBP, DBP), body mass index (BMI) and waist to hip circumference (WHC) was performed. Fasting blood sample was drawn for sugar (FBS), total cholesterol (TC) and triglyceride (TG) and a 2-hour postprandial glucose was also measured. In this study performed on 12494 subjects, 48% were males and 52% females. The mean age of men and women was 38.99±15.30 and 38.80±14.54 years 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 under control in 6.4% of the men and 13.8% of the women. In 86.5% of men with high BP and 89.3% of women with high BP, at least one other cardiovascular risk factor was present and its prevalence increased with age in both genders. BMI >25 (especially abdominal obesity) was the most frequent associated risk factor (41.9% in male, 59% in female). Except for smoking, the prevalence of each cardiovascular risk factor increased with the severity of hypertension, except in young women. The prevalence of high BP- even in treated subjects- is high in Iran. Many subjects with high BP have at least one other associated cardiovascular risk factor. These data emphasize the necessity of implementing community-based interventions.
