Methods: In this systematic review and meta-analysis study, the databases of Scopus, PubMed, web of science, SID, Magiran, Iranmedex, IranDoc and Google Scholar, the references of selected articles and unpublished sources (conferences, thesis) with the keywords of Breastfeeding, Exclusive, Prevalence and Iran were evaluated from 2010-2019. The Strobe checklist was used to assess the quality, the I2 index was used to assess the heterogeneity, and the Egger’s test was used to assess the diffusion bias. The random effects model was used for the combined prevalence and odds ratio with 95% confidence interval. Data were analyzed by Stata software (version 16). Results: From 30 studies that their results were extracted, 19740 children were examined. The prevalence of exclusive breastfeeding was 0.49 (CI 95%; 0.38-0.59). The exclusive feeding odds ratio for type of delivery was 1.36 (CI 95%; 1.7-1.72), for education level was 1.36 (CI 95%; 1.01-1.84) and for maternal occupation was 2.15 (CI 95%; 1.09-4.23).
