Abstract

The data on the prevalence of nutritional anemia among the urban elderly population in India was limited. Hence, the present study was carried out with an aim to assess the prevalence of nutritional anemia and its association with vitamin B12, folate, ferritin and homocystine among the urban elderly population. A community- based cross-sectional study was carried out among 282 urban elderly (≥ 60 years) subjects (186 males and 96 females) in Hyderabad. Fasting blood samples were collected and hemoglobin (Hb) was estimated by cyanmethemoglobin method. Plasma Folic acid and vitamin B12 levels were estimated by RIA and homocysteine and ferritin levels were estimated by ELISA methods. The overall prevalence of anemia (Hb < 12 g/dL for females and < 13 g/dL for males) among the urban elderly was 20.6% and the prevalence was found to be increasing with the age. The prevalence of vitamin B12 (< 203 pg/mL), folic acid (< 4 ng/mL), ferritin (< 15 ng/mL) and hyperhomocysteinemia (≥ 12 µmol/L) in these subjects was 36.0%, 8.2%, 1.1% and 24.3% respectively. The prevalence of anemia due to deficiencies of iron (ferritin < 15 ng/mL), folate and vitamin B12 was 5.45%, 9.1% and 42.3% respectively. A significant association was observed between the prevalence of anemia with ferritin and hyperhomocysteinemia. In conclusion, the prevalence of anemia and nutritional anemia among the urban-based elderly was 20.6% and 56.85% respectively. The association of anemia with hyperhomocysteinemia needs further studies.
