Hypertension (HTN) is an important risk factor for cardiovascular disease (CVD) mortality and morbidity among Iranians. The present study aimed to estimate the prevalence of pre-HTN and HTN and some of its related factors in south of Iran. This cross-sectional survey was conducted on the data of the Persian cohort study in Kherameh. The participants consisted of 10,663 people aged 40–70 years. HTN was defined as either systolic/diastolic blood pressure (SBP/DBP) ≥140/90 mmHg or taking medications. Pre-HTN was defined as SBP = 120–139 mmHg and/or DBP = 80–89 mmHg. The logistic regression method was used to identify the factors associated with pre-HTN and HTN. The age-standardized prevalence rate (ASPR) of pre-HTN was 19.66% (95% CI: 19.45–19.86%) and 18.59% (95% CI: 18.36–18.83%) in males and females, respectively. Also, the ASPR of HTN was 21.44 (95% CI: 21.22–21.65%) in males and 33.53% (95% CI: 33.22–33.85%) in females. Male gender, old age, being unemployed, low education level, high body mass index (BMI), no smoking, diabetes, cerebro-cardiovascular disease, suffering from another chronic disease, family history of CVD, and negative family history of cancer and other chronic diseases were independently associated with pre-HTN (p < 0.05). All variables, except for gender, smoking, and family history of cancer, were significantly associated with HTN. Drug abuse was also correlated to HTN (p < 0.05). This study revealed the increased prevalence of HTN in rural and urban areas. Therefore, the health system needs to develop strategies to raise the accessibility of screening and diagnostic services.

高血压 (HTN) 是伊朗人心血管疾病 (CVD) 死亡率和发病率的重要危险因素。本研究旨在估计伊朗南部前 HTN 和 HTN 的患病率及其一些相关因素。这项横断面调查是对 Kherameh 波斯队列研究的数据进行的。参与者包括 10,663 名年龄在 40-70 岁之间的人。HTN 定义为收缩压/舒张压 (SBP/DBP) ≥ 140/90 mmHg 或服用药物。Pre-HTN 定义为 SBP = 120-139 mmHg 和/或 DBP = 80-89 mmHg。使用逻辑回归方法确定与前 HTN 和 HTN 相关的因素。男性和女性 HTN 前的年龄标准化患病率 (ASPR) 分别为 19.66% (95% CI: 19.45–19.86%) 和 18.59% (95% CI: 18.36–18.83%)。此外，HTN 的 ASPR 为 21。44 (95% CI: 21.22–21.65%) 男性和 33.53% (95% CI: 33.22–33.85%) 女性。男性、高龄、失业、受教育程度低、体重指数（BMI）高、不吸烟、糖尿病、心脑血管疾病、患有其他慢性病、心血管疾病家族史、癌症家族史等慢性疾病与前 HTN 独立相关（p  < 0.05)。除性别、吸烟和癌症家族史外，所有变量都与 HTN 显着相关。药物滥用也与高血压相关（p  < 0.05）。这项研究揭示了农村和城市地区高血压患病率的增加。因此，卫生系统需要制定策略以提高筛查和诊断服务的可及性。
