Introduction: the systematic blood donation and female gen derenhance the development of iron deficiency causing in adequate supply of blood and commitment to the health of the donor. Few studies have evaluated the interaction between gender and type of donor that is required for integrating the information. Objective: to determine the prevalence of iron deficiency in systematic blood donors and analyze its association with gender, from a meta-analysis. Methods: a comprehensive and reproducible search of the literature in 7 databases. Over all and specific prevalence by genderand donor type were determined. Prevalence ratios and odds were calculated. Meta-analytic analysis under the random effects model were performed. Results: a sample of 9 260 donors, first time and systematic donors, of both sexes between 18 and 67 years old,was obtained. The overall prevalence of iron deficiency was 12,25 % (95 % CI: 11,57 % to 12,92 %); women had 98 % higher prevalence of the event than men and were 3,03 times more frequent in systematic donors than those in the first time. The overall probability of developing deficiency in systematic donors was 4,28 times higher (95 % CI2, 65 to 6,89) than the value observed in first time donors. The prevalence found was similar to that obtained in high-risk groups such aspregnant women, being higher in women and in systematic donors, factors that interact to enhance the like lihood of developing iron deficiency. It is necessary to focus on the health care of the donor to comply with ethical and political issues.
