“…Among the year-old children, however, the incidence of low hematocrits was even higher; 27.4 per cent of the whites and 40 per cent of the nonwhites had hematocrits of 31 per cent or less, and 10 per cent of the whites and one-quarter of the nonwhites had hematocrits of 30 per cent or under, indicating a more serious degree of anemia. Low hemoglobin level was also most common among the younger children in a group whom Gutelius (1969) examined at a child health center in Washington, D.C. Iron-deficiency anemia, determined by hemoglobin level and corroborative red cell pathology, was found among 28.9 per cent of the whole group of 460 Negro preschoolers, but children in the age group 12-17 months had a rate of anemia of 65 per cent. Gutelius points out, moreover, that these were probably not the highest-risk children, since the poorest and most disorganized families did not come from well-baby care at all, and of those who did attend, the test group included only children who had not previously had a hemoglobin determination-that is, they were children judged to be "normal" by the clinic staff.…”
