Abstract

Objective: Anemia is a common public health concern in patients with type 2 diabetes worldwide. This study aimed to identify the prevalence of anemia among patients with diabetes. Methods: Electronic databases, including PubMed, Scopus, Web of Sciences, and Google Scholar, were searched systematically for studies published between 2010 and 2021. After removing duplicates and inappropriate reports, the remaining manuscripts were reviewed and appraised using theNewcastle-Ottawa Scale (NOS) tool. A random-effects model was used to calculate the pooled estimates of the extracted data using Stata version 17. Heterogeneity of the studies was assessed using the Q statistic. Results: A total of 51 articles containing information on 26,485 patients with diabetes were included in this study. The articles were mainly from Asia (58.82%) and Africa (35.29%). The overall prevalence of anemia was 35.45% (95% CI: 30.30–40.76), with no evidence of heterogeneity by sex. Among the two continents with the highest number of studies, the prevalence of anemia in patients with diabetes was significantly higher in Asia [40.02; 95% CI: 32.72–47.54] compared to Africa [28.46; 95% CI: 21.90–35.50] (P for heterogeneity = 0.029). Moreover, there has been an increasing trend in the prevalence of anemia in patients with diabetes over time, from [15.28; 95% CI: 9.83–22.21] in 2012 to [40.70; 95% CI: 10.21–75.93] in 2022. Conclusion: Globally, approximately 4 in 10 patients with diabetes suffer from anemia. Therefore, routine anemia screening and control programs every 3 months might be useful in improving the quality of life of these patients. © 2024 The Editorial Board of Biomedical and Environmental Sciences
