Abstract
In a hematologic survey conducted in 1972, microcythemia in school children was found to be associated with microcythemia in other family members. The association of cultural characteristics of chronic poverty with reduced red cell volume suggested nutritional iron deficiency. A resurvey of families was made in 1975. For 39 children between the ages of 3 and 10 years at the time of both surveys, mean hemoglobin concentration (HGB) decreased from 21.0 g/dl to 10.8 g/dl. Thirteen infants, 6 months to 3 years of age in 1972, in the resurveyed families had mean HGB of 11.5 g/dl as compared to 10.4 g/dl for 9 similarly aged children newly born into the resurvey families. The rate of somatic growth was unchanged during the interval between survey. During the interval between 1972 and 1975, food costs rose nationally, and the purchase of meat products decreased both nationally and (as found in this study) locally. The data suggest that the high cost of foods rich in micronutrients may increase the prevalence of iron deficiency in an impoverished community.
