ANEMIA IN FAMILIES OF IRON DEFICIENT INNER-CITY SCHOOL CHILDREN: A FOLLOW-UP STUDY, 1972–1976

A hematologic survey conducted in 1972 Identified 68 of 1210 children 5 to 8 years of age as iron deficient. The 68 families were investigated; in 1975, 38 of the families were reinvestigated. In 1975, 9 Infant children had a mean hemoglobin concentration (HGB) of 10.4 gn/dl (SD=0.97) as compared to a mean HGB of 11.5 (SD=1.38) for 13 similarly-aged children in these same 38 families in 1972 (p<0.005). For 39 children 3 to 10 years of age at both times of testing, mean HGB was 10.8 In 1975 as compared to 12.0 in 1972 (p<0.001). For the 1210 children originally surveyed in 1972, mean HGB was 12.25 (SD=1.03). In 1976 a survey of 221 similarly-aged children in a single school revealed a mean HGB of 11.8 (SD=1.04) (p<0.001).During the period between investigations, there were dramatic changes in food costs, and nationally, in patterns of food consumption. A survey of local supermarket sales showed significant reductions in purchases of meat products in the impoverished area of Philadelphia where these investigations took place; no such change was demonstrated in a prosperous area of the city.A rise in the prevalence of specific nutrient deficiency is known to occur in underdeveloped countries in association with rises in the cost of food staples. The data presented herein suggests that a similar phenomenon has occurred here.
