Prevalence of diabetes, hypertension and cardiovascular disease in patients with COVID-19: a systematic review and meta-analysis


Right now, there is small data on the prevalence of predominant chronic diseases. In addition, it is important for healthcare providers to know the underlying diseases in COVID-19 infected patients. The aim of present systematic review and meta-analysis was conducted on the Prevalence of diabetes, Hypertension and cardiovascular diseases in patients with COVID-19. MEDLINE, PubMed, Cochrane Library, Embase, ISI, google scholar were the electronic databases that used to perform a systematic literature between 2010 to March 2020. Endnote X9 software was used for managing the electronic titles. Searches were performed using these keywords: “COVID-19 OR novel coronavirus OR 2019-nCoV OR Corona Virus Disease”, “diabetes”,” Hypertension”,” cardiovascular disease”. The present systematic review was done based on the main consideration of PRISMA Statement–Preferred Reporting Items for Systematic Reviews and Meta-analysis. The result of the electronic and manual search was a total of 168 potentially relevant titles and abstracts but finally nine studies were included. Meta-analysis reported that 0.19 (95% CI: 0.06-0.13) of SARS-CoV-2 cases were Diabetes. Regarding the I2 index, which was calculated to be 66.9% and the Chi-square test, there was significant heterogeneity between the resources (P=0.01). Hypertensions were the most prevalent underlying diseases in COVID-19 patients.
