Objectives: To evaluate the prevalence and associated risk factors of iron deficiency anemia (IDA)in Saudi Arabia. Methods: A thorough search of pertinent databases was done in order to find studies that satisfied the requirements for inclusion. A thorough search of PubMed, Web of Science, SCOPUS, and Science Direct was conducted to find pertinent literature. Results: Nineteen studies, including a total of 20,929 participants and 18,236 (87.1%) of them were females, were included in our data. The prevalence of IDA in the total population ranged from 9.8% in preschool children and 75.3% in pregnant women, and the pooled prevalence was 7043 (33.7%). Regarding pregnant women and women in the childbearing period, the incidence of IDA was significantly correlated with increased gravidity, parity, use of tea and coffee, primiparas, younger moms, those without prenatal care or iron supplements, menorrhagia, antacid or nonsteroidal antidepressant use histories, family and personal history of IDA, occasional meat consumption, and inadequate iron and vitamin C intakes. The improved socioeconomic position of Saudi Arabian children did not affect the prevalence of IDA. Obesity, supplement consumption, and a positive family history of IDA were significantly associated with the increased prevalence of IDA. Conclusion: The prevalence among pregnant women, women in the childbearing period, children, and adolescents in Saudi Arabia is still high. The study's conclusions emphasize the need to increase public knowledge of the value of a balanced diet and the regular inclusion of foods high in iron in daily meals. The findings of this study provide valuable insights into the risk variables that raise the prevalence of IDA in the study area and serve as a roadmap for future research endeavors addressing IDA.
