Prevalence of hypertension in Ghanaian society: a systematic review, meta-analysis, and GRADE assessment
Abstract
Background Hypertension has become an important public health concern in the developing world owing to rising prevalence and its adverse impact on ailing health systems. Despite being a modifiable risk factor for cardiovascular disease, hypertension has not received the needed attention in Ghana as a result of various competing interests for scarce health resources. This systematic review and meta-analysis provides a comprehensive and updated summary of the literature on the prevalence of hypertension in Ghana. Methods Major databases such as MEDLINE, EMBASE, and Google Scholar and local thesis repositories were accessed to identify population-based studies on hypertension among Ghanaians. Data extracted from retrieved reports were screened independently by two reviewers. The quality of eligible studies was evaluated and reported. A reliable pooled estimate of hypertension prevalence was calculated utilizing a random-effects model and reported according to the GRADE framework. Additionally, a meta-regression analysis was performed to analyze the contribution of study-level variables to variance in hypertension prevalence. Results In general, a total of 45,470 subjects ( n = 22,866 males and 22,604 females) were enrolled from urban ( n = 12), rural ( n = 8), and mixed populations ( n = 7). Blood pressure (BP) was measured across studies according to a validated and clinically approved protocol by trained field workers or healthcare workers including nurses and physicians. A…
