Background and Objective: hypertension is one of the most common global health problems and the leading cause of premature mortality worldwide. This study aims to investigate the epidemiological characteristic and the spatial-temporal variations of the admission rate of hypertension in Zanjan province, Iran, during ۲۰۱۴-۲۰۱۹. Materials and Methods: Data were obtained from nine health information system (HIS) databases. Univariate chi-square and T-test methods were used to test the hypothesis, and binary logistic regression was used to model the probability of admission due to hypertension. Results: Sixty-eight thousand eight hundred forty-three patients have been hospitalized due to cardiovascular diseases in Zanjan province, Iran, and ۵۹۳۱ cases had hypertension. The admission rate of hypertension was ۵۵۵ cases per ۱۰۰,۰۰۰ which were higher in women than in males (۷۵۵ cases vs. ۳۵۷) (P<۰.۰۰۱). The highest admission rate of hypertension was detected in the age group over ۸۰ and in Khoramdareh county, Zanjan province, Iran (P<۰.۰۰۱). The probability of admission due to hypertension was increased by aging in all regions, which was higher among women and in the Southeast study area. Conclusion: This study shows the high admission rate of hypertension in Zanjan province, Iran, from ۲۰۱۴-۲۰۱۹. It is a warning to policymakers and local health authorities to increase their efforts to reduce the incidence of hypertension by identifying the principal main risk factors and applying periodic screening programs in high-risk, high areas.
