Prevalence of Hypertension Among the Rural Adult Population in India: A Systematic Review and Meta-Analysis

Hypertension is a major cause of premature death worldwide. Studies have shown that the rural adult population in India is also experiencing this burden. To determine the overall pooled prevalence of primary hypertension in the adult rural population of India, an extensive search was conducted in various databases such as MEDLINE/PubMed, IndMED, EBSCO, CINAHL, and Google Scholar from 01/01/2014 to 16/05/2024. The studies were reviewed by two authors independently, assessing their quality and extracted data using pre-coded spreadsheets. The pooled estimates of hypertension prevalence were calculated using the Der Simonian-Laird random effects model, and subgroup, sensitivity analyses, and meta-regression were performed. In the final review, a total of 10 studies involving 30757 subjects were included. The combined pooled estimate of hypertension prevalence was 24% (95% CI: 19, 29) and there was a significant level of heterogeneity observed among the studies (I =98%, Q=572.07, df=9, p
