The folacin and iron status of 193 adolescents from urban low-income households was evaluated. Red blood cell folacin concentrations were less than 140 ng/ml in 42% of the subjects and 140 to 159 ng/ml in 13%. Of the serum folacin values, 45% were less than 6 ng/ml, and 15% were below 3 ng/ml. Serum folacin levels decreased with increasing age (p less than 0.01) and sexual maturity (p less than 0.05). Transferrin saturation was low (less than 16%) in 12% of the females and 2% of the males. Transferrin saturation levels for females declined as age increased in contrast to an increase over age in males (p less than 0.01). Eleven percent of the females and 3% of the males were classified as anemic (less than 12 g/dl). Mean cell Hb concentration was low (less than 32%) in 24% of the females and 7% of the males. Of all subjects, 17% had low mean cell volumes (less than 81 mum 3). These findings demonstrate folacin and iron status is less than adequate in a significant proportion of this adolescent population group.

One objective of the Food Stamp Program (FSP) is to supplement food expenditures of low income households to enhance the household's ability to provide nutritionally adequate diets. A household may consist of any person, or group of persons, who purchase, store and prepare food. Program eligibility is based on net household income, total assets and household size. Eligible households purchase coupons which are used in retail food outlets. Households of equal size receive coupon allotments of equal purchasing value, but the cash purchase requirement varies with net income. Bonus stamps represent the difference between the purchase requirement and the coupon allotment value.

The folacin and iron status and hemotological parameters of 193 persons 60 years of age and older from urban low-income households were evaluated. Of the serum folacin values 30% were between 3 and 6 ng/ml and 8% were below 3 ng/ml. Of these subjects 60% could be classified as "high risk" (less than 140 ng/ml) and 11% as "medium risk" (140 to 160 ng/ml) based on red blood cell folacin concentrations. Serum iron was normal (greater than 50 micrograms/dl) for all subjects as was transferrin saturation (greater than 15%). Hematological indices showed a 14% incidence of anemia (hemaglobin less than 12 g/dl), and 32% incidence of leukopenia (leukocytes less than 4.8 X 10(3)). These findings demonstrate widespread folacin deficiency and no evidence of iron deficiency in these elderly people.
