Hypertension is a leading cause of mortality and morbidity globally. This study aimed to obtain an overall regional estimate of the prevalence of hypertension and pre-hypertension and present the disease pattern based on the age and time in the Middle East region. We searched PubMed, Google Scholar, Medline for articles on the prevalence of hypertension, pre-hypertension among countries of the Middle East region from 1999 to 2019. STATA-14 was used to analyze the data. Data were pooled using a random-effects meta-analysis model, and heterogeneity between studies was assessed using I2 test and subgroup analysis. A total of eighty-three studies with 479816 participants met the criteria for inclusion in the meta-analysis process. The overall prevalence of hypertension and pre-hypertension in the Middle East region were 24.36% (95% CI: 19.06–31.14) and 28. 60% (95% CI: 24.19–33.80), respectively. An increasing trend in the prevalence of hypertension was observed with the increasing age. The prevalence of hypertension in the ≤ 49-year-old age group was 17.13% (95% CI: 13.79–21.27) and in people over 60 years was 61.24% (95% CI: 55.30–67.81) (P < 0.001). This pattern has been similar among both males and females. On the other hand, a decreasing trend in the prevalence of pre-hypertension was observed with the increasing age. The increasing trend in the prevalence of hypertension and decreasing trend in the prevalence of pre-hypertension with age are significant concerns in the Middle East region. Screening for the prevention and control of hypertension should prioritize public health programs.
