Prehypertension is a borderline blood pressure status associated with both higher incidence of cardiovascular disease as well as higher risk of progression to hypertension. The rising burden of hypertension and prehyperension globally is a serious concern to all and sundry. This study aims to estimate the burden of prehypertension in Nigeria. Online searches of Google Scholar, PubMed and African Index Medicus were conducted and studies selected based on predefined criteria. 21 studies consisting of 25839 individuals conducted between 2011 and 2021 were included in the meta-analysis. The pooled prevalence of prehypertension in Nigeria was found to be 34%
(95% CI: 30%-40%) translating to 41.4 million adult Nigerians. Males have higher prehypertension prevalence of 39.1% (95% CI: 30.9%-47.6%) than females with prevalence of 28.5% (95% CI: 21.2%-36.4%). Differences between sexes are not statistically significant. The region with the lowest prehypertension prevalence is North-East at 18%. The region with the highest prevalence of prehypertension is North-West at 43%. Differences between the regions are statistically significant. The pooled prevalence in rural settlements is 32% whereas the pooled prevalence for urban settlements is 37%. Differences rural and urban settlements were not statistically significant. In conclusion, the burden of prehypertension in Nigeria is high and represents a future burden of hypertension and other cardiovascular diseases
