Medical evaluation of the special supplemental food program for women, infants, and children

Abstract

The special supplemental food program for women, infants, and children administered by the United States Department of Agriculture, was evaluated nationally. Participating infants, children under 4 years old, and pregnant and nursing women were investigated initially, and after receiving food supplements. The supplements were iron-fortified infant formula, iron-fortified infant cereals, and fruit juices for the infants, and milk, cheese, iron-fortified cereals, eggs, and fruit juices for the children and women. Initially, the average birth weight was lower and the infant mortality rate was higher than expected in a well nourished population. There was also evidence of slight growth retardation, a high anemia rate, and a high percentage of participants having saturation of transferrin values less than 15%. The program had no effect on the prevalence of unsatisfactory values for saturation of transferrin. There was an increase in weight gain during pregnancy, an increase in birth weight, an acceleration of growth, and a reduction in the anemia rate in all participant categories except women in the first and second trimesters of pregnancy.
