We describe the relationships between hemoglobin level and race, <jats:italic>Plasmodium<\/jats:italic> species, and days of illness in 150 Colombian patients with uncomplicated malaria diagnosed by thick blood smear. Hemoglobin was measured at admission and a standardized questionnaire was used to determine days of illness and other variables. Associations between hemoglobin and the variables were estimated and adjusted according to the other covariates using regression analysis. <jats:italic>Plasmodium falciparum<\/jats:italic> and <jats:italic>P. vivax<\/jats:italic> were found in similar proportions and mild anemia was present in 50% of the patients. Volunteers were classified as Afro-Colombians (61%) and non-Afro-Colombians (39%). An inverse relationship between hemoglobin and days of illness was identified, and a statistical interaction was found between race and <jats:italic>P. falciparum<\/jats:italic> infection in determining the hemoglobin concentration. These observations could guide the design of research to better understand malarial anemia.<\/jats:p>","DOI":"10.4269\/ajtmh.2005.73.50","type":"journal-article","created":{"date-parts":[[2017,5,10]],"date-time":"2017-05-10T16:41:16Z","timestamp":1494434476000},"page":"50-54","source":"Crossref","is-referenced-by-count":11,"title":["HEMOGLOBIN LEVELS RELATED TO DAYS OF ILLNESS, RACE, AND PLASMODIUM SPECIES IN COLOMBIAN PATIENTS WITH UNCOMPLICATED MALARIA"],"prefix":"10.4269","volume":"73","author":[{"given":"FELIPE","family":"ZAMORA","sequence":"first","affiliation":[{"name":"Instituto de Inmunologi\u0301a del Valle, Cali, Colombia;
