Overview of hypertension in Saudi Arabia: A systematic review and meta-analysis

Abstract

Objectives: To assess the prevalence, awareness, treatment, and control of hypertension in Saudi Arabia.

Methods: We searched electronic databases and the references lists of found publications between 1990 and 2022. Original cross-sectional studies in English were included using PubMed, Google Scholar, and the Saudi Digital Library. A meta-analysis was performed to assess the combined prevalence, awareness, treatment, and control rates of hypertension.

Results: Twenty-nine studies with 278873 individuals aged 14-100 were considered. The pooled prevalence of hypertension was 22.66% (95% CI:18.95-26.60), Cochran's Q=6221.98, dff=22, p<0.0001; I²=99.65%, Egger's test (p=0.0033) across 23 studies with 272378 people. The pooled hypertension awareness rate was 42.8% from 6 studies with 36046 participants (95% CI:35.66-50.01), Cochran's Q=781.86, dff=5, p<0.0001; I²=99.4% and Egger's test p=0.3772. The pooled proportion of hypertension patients treated in 6 studies involving 46075 samples was 59.4% (95% CI=38.14-79.02), Cochran's Q=9793.79 dff=5, p<0.0001; I²=99.95%, Egger's test p=0.8284. The pooled proportion of hypertension-controlled participants across 15 studies comprising 264817 subjects was 34.97% (95% CI: 27.62-42.68), Cochran's Q=11048.28, dff=14, p<0.0001; I²=99.87% and Egger's test p=0.9760.

Conclusion: The prevalence of hypertension was high, with low awareness, treatment, and control rates among Saudis. Therefore, policymakers and healthcare providers must work harmoniously to promote health and to prevent, detect, and control hypertension early.PROSPERO Reg. No.: CRD42023407978.
