title: Distribution of haemoglobin in patients presenting to their general practitioner, and its correlation with serum ferritin.
abstract: We have conducted a survey in the United Kingdom in order to evaluate the prevalence of anaemia and of iron deficiency in elderly male and female patients and in female patients of child-bearing age presenting to their general practitioner. Although haemoglobin values were approximately normally distributed, there was evidence of a bimodal distribution of serum ferritin values, particularly in elderly men. A correlation between serum ferritin and haemoglobin values was found to exist, both in the elderly and in younger women. The overall prevalence of anaemia in the study population was 14.3%, although it was higher for elderly men (20.1%) than either elderly women (13.7%) or women of child-bearing age (11.9%). Iron deficiency associated with anaemia was more common in elderly men (45.2% of those anaemic) than elderly women (28.6%) or women of child-bearing age (25.6%). This survey indicates that the prevalence of anaemia among certain groups of high risk patients presenting for consultation to their general practitioner is about 1 in 7, although the prevalence is as high as 1 in 5 in elderly men.
