Trends In Blood Pressure Level and HTN in Isfahan A. R. Khosravi MD, et al Trends in Blood Pressure Level, Prevalence and Control of Hypertension in Isfahan, Iran

Objectives- This study aimed at evaluating the trends in hypertension prevalence and control during the last decade. Methods- We drew upon four independent cross-sectional population surveys conducted in 1992, 1996, 1999 and 2001 in Isfahan, Iran. Results-The prevalence of hypertension had a downward trend from 31.8 % in 1992 to 17.5% in 2001. The mean systolic (SBP) and diastolic blood pressure (DBP) decreased in both sexes. The mean SBP decreased from 142.24 to 116.8 mmHg in men and from 143.07 to 113.7 mmHg in women. Regarding DBP, this decrease was from 92.5 to 73.8 mmHg in men and from 92.2 to 72.8mmHg in women (P<0.05). The proportion of hypertensives who were aware of their condition increased from 46.2 % to 50.1% (P<0.05), and the proportion of hypertensive subjects with adequately controlled blood pressure increased from 2.8 % to 12 % (P<0.05). Conclusion- Hypertension care has improved significantly during the last decade, which is probably the result of the implementation of different population-based national plan
