Abstract

Introduction: Anemia is one of the most common hematologic problems occurs among patients with tuberculosis (TB). Many studies have been carried out estimating the prevalence of anemia among TB patients in different countries reported various results. This study aims to estimate the combined estimate of the anemia prevalence among these patients using systematic review and meta-analysis. Methods: Required primary studies were provided after a comprehensive and systematic search in PubMed, Scopus, Science direct, Web of Science and also Google scholar search engine. These studies were then quality assessed using Newcastle–Ottawa Scale checklist. Random effects model was applied for combining the point prevalence with 95% confidence intervals. Results: Of 41 papers entered into the meta-analysis, prevalence (95% confidence interval)of anemia among all TB patients as well as men and women were 61.53% (53.44–69.63), 66.95% (51.75–82.14)and 72.67% (60.79–84.54)respectively. Prevalence (95% confidence intervals)of mild, moderate and severe anemia were 35.67% (27.59–43.46), 31.19% (25.15–37.24)and 11.61% (7.88–15.34)respectively. In addition, prevalence (95% confidence intervals)of chronic disease anemia and iron deficiency anemia were 49.82% (15.58–84.07)and 20.17% (6.68–33.65)respectively. Conclusion: Prevalence of anemia among TB patients was high especially among women. More than 43% of these patients suffered from moderate and severe anemia and about half of them had chronic disease anemia. © 2019 Tuberculosis Association of India
