Vitamin B12 status of elderly persons from urban low-income households.
Vitamin B12 status was evaluated in 111 noninstitutional elderly persons (age range, 60-87 years) living in an urban poverty area. The sample was predominantly black (90 subjects); the rest were Spanish Americans. Serum vitamin B12 levels were all normal (greater than 200 pg/ml) and ranged from 226 to 1200 pg/ml (mean +/- SD = 700 +/- 191 pg/ml). The findings indicate that vitamin B12 deficiency was not a problem in this elderly population.
