Anaemia is quite common in older adults, with prevalence rates of 10–25% in those over 65 years of age.^11,12 The risk of developing anaemia increases with age: up to 50% of those older than 80 are anaemic.¹¹ It is also quite prevalent in older hospitalized patients and can affect up to 50% of nursing home residents.¹³ Men, particularly African American males, appear to be at higher risk.¹³ Worldwide and across all age groups, the most common type of anaemia is iron deficiency anaemia. However, the most common type of anaemia found in the older adult population is anaemia of chronic disease. One study conducted on Austrian seniors ages 64 and above by Bach et al. evaluated the causes of anaemia in older age groups and found anaemia of chronic disease to have the highest prevalence (62.1%), followed by anaemia of chronic kidney disease (11.3–45.1%, depending on glomerular filtration rate used), multifactorial causes (28.1%), iron deficiency (14.4%), clonal disorders (10%), folate deficiency (6.7%), and vitamin B12 deficiency (2%)¹³ (Figure 22.2).
