Hemoglobin levels, vitamin B12, and folate status in a Himalayan village

Abstract
A survey of 52 adult inhabitants of Tibetan ancestry in a village located at 12,000 feet in the Nepal Himalayas revealed lower hemoglobin levels than that reported for populations living at similar altitude elsewhere in the world. However, serum B12, serum and red cell folate, and mean corpuscular hemoglobin concentrations gave no evidence for megaloblastosis or iron deficiency as a cause of anemia. Although the role of other deficiencies such as iodine remains to be evaluated, present data do not suggest that the lower hemoglobin values found are indicative of anemia in this population.
