住院新型冠状病毒肺炎患者糖尿病患病率及其影响的系统回顾和meta分析

Abstract Background Diabetes is a cardiometabolic comorbidity that may predispose COVID‐19 patients to worse clinical outcomes. This study sought to determine the prevalence of diabetes in hospitalized COVID‐19 patients and investigate the association of diabetes severe COVID‐19, rate of acute respiratory distress syndrome (ARDS), mortality, and need for mechanical ventilation by performing a systematic review and meta‐analysis. Methods Individual studies were selected using a defined search strategy, including results up until July 2021 from PubMed, Embase, and Cochrane Central Register of Controlled Trials. A random‐effects meta‐analysis was performed to estimate the proportions and level of association of diabetes with clinical outcomes in hospitalized COVID‐19 patients. Forest plots were generated to retrieve the odds ratios (OR), and the quality and risk assessment was performed for all studies included in the meta‐analysis. Results The total number of patients included in this study was 10 648, of whom 3112 had diabetes (29.23%). The overall pooled estimate of prevalence of diabetes in the meta‐analysis cohort was 31% (95% CI, 0.25‐0.38; z = 16.09, P <.0001). Diabetes significantly increased the odds of severe COVID‐19 (OR 3.39; 95% CI, 2.14‐5.37; P <.0001), ARDS (OR 2.55; 95% CI, 1.74‐3.75; P = <.0001), in‐hospital mortality (OR 2.44; 95% CI, 1.93‐3.09; P <.0001), and mechanical ventilation (OR 3.03; 95% CI, 2.17‐4.22; P <.0001). Conclusions Our meta‐analysis demonstrates that diabetes is significantly associated with increased odds of severe COVID‐19, increased ARDS rate, mortality, and need for mechanical ventilation in hospitalized patients. We also estimated an overall pooled prevalence of diabetes of 31% in hospitalized COVID‐19 patients.
