Background: The prevalence of cardiovascular diseases (CVDs) and Type 2 diabetes mellitus (T2DM) has increased in Bangladesh. This paper reviewed published studies on HTN and T2DM from 2010 to 2020 in Bangladesh and conducted a meta-analysis on these diseases.
Methods: The PubMed database was used for systematic search. Hypertension (HTN) and T2DM were considered for measuring pooled prevalence by meta-analysis. The random-effects model was used to calculate the pooled prevalence of HTN (n=30) and T2DM (n=21) relevant studies. The quality of the reviewed studies was determined by sampling strategy, sample size and outcome assessment. The protocol of the meta-analysis has been registered at PROSPERO (CRD42020206315), and the study is not funded by any organizations.
Results: The pooled HTN and T2DM prevalence were 21.6% (95% CI: 18.8%−24.4%) and 13.6% (95% CI: 10.8%−16.5%), respectively. Females were more hypertensive than males (M vs. F: 18.6% vs.24.8%), and T2DM was higher in females (M vs. F: 12.4% vs. 13.3%). Urban dwellers were more hypertensive and diabetic than rural people (urban vs. rural: 28.5% vs. 20.3% and 18.8% vs. 14.2%, respectively). A total of 8% increase in the total prevalence of HTN and T2DM became more than double compared to the 1995-2010 period.
Conclusion: Future research should focus on the underlying factors that increase the prevalence of these diseases and prevention strategies to reduce the trend of increasing prevalence.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
