Abstract

This study aimed to determine the influence of yerba mate infusion and iron supplements on hemoglobin levels in pregnant women in Uruguay. A cross-sectional study was conducted with a sample of 95 postpartum women, aged 18 to 45 years, who were human milk donors. The study assessed yerba mate and iron supplement consumption habits, as well as the prevalence of anemia during pregnancy. Results showed that 2.4% of women had anemia at the beginning of pregnancy and 14.3% at the end. Additionally, 53% of the women consumed yerba mate, 2.2% did not use iron supplements, and 15.7% did not meet daily iron requirements. No significant differences were found between yerba mate consumption, iron supplementation, and anemia. In conclusion, hemoglobin levels decreased, and anemia prevalence increased as pregnancy progressed, with no significant differences linked to yerba mate or iron supplement consumption.
