Abstract
Objectives:
hypertension (HTN) is one of important risk factors of cardiovascular disease. Considering the importance of this disease for public health, this study was designed in order to determine the prevalence, awareness, treatment, control and risk factors of hypertension in Iranian adult population.
Method:
This cross-sectional study was conducted on 2107 residents of Isfahan, Iran. Samples were selected through random, multistage, cluster sampling in 2015-2016. Outcome variable was hypertension determined by measuring right arm blood pressure via an arm digital blood pressure monitor. Awareness, treatment and control of HTN was assessed by a valid and reliable researcher-made questionnaire. Other demographic and clinical variables were assessed via a demographic questionnaire.
Results:
The overall prevalence of hypertension was 17.3% (18.9% and 15.5% in men and women, respectively). The prevalence of hypertension increased in both genders with age. the prevalence of awareness of HTN among people with HTN was 69.2% of which 92.4% and 59.9% had drug treatment and controlled HTN, respectively. Logistic regression identified age, BMI, having diabetes and hyperlipidemia and positive family history of HTN as determinants of awareness of HTN.
Conclusions:
The results showed that hypertension is highly prevalent in the community, especially in men and in the middle-aged and older adults. Approximately 30% of patients are unaware of their disease, and there is less awareness among younger adults. Despite high frequency of drug treatment for hypertension, hypertension is uncontrolled in more than 40% of patients. Health policies should therefore consider appropriate preventive and therapeutic strategies for these high-risk groups.
