Scope

What is the prevalence of anaemia in the general population?

Definition

Rate (age, sex ratio) Context (population size studied, location, date data taken, end-point measured) Definition of end-point Reference
pre-school age: 21.7%
pregnant women: 25.1%
non-pregnant women: 19%
Worldwide, 1993-2005, anaemia Haemoglobin threshold (g/l)
Children (0.50–4.99 yrs) 110
Children (5.00–11.99 yrs) 115
Children (12.00–14.99 yrs) 120
Non-pregnant women (≥15.00 yrs) 120
Pregnant women 110
Men (≥15.00 yrs) 130
[1]
Females, 17-38yrs
iron deficiency = 19.3 %
borderline iron status = 11.4 %.
n=543, Clermont-Ferrand (France), iron status iron deficient (serum ferritin <15µg/L)
iron depletion borderline (serum ferritin 15–20 µg/L)
iron replete (serum ferritin > 20 µg/L).
[2]
Europe = 10% Estimated prevalence (%) of anaemia (1990-1995) by WHO Region based on haemoglobin concentration See previous WHO definition [3]
9-12 months
iron deficiency = 14.0%
iron deficiency anaemia = 9.4%.
Estonia, iron deficiency and iron deficiency anaemia Anaemia was defined when haemoglobin level was lower than 105 g/L, and iron deficiency when ferritin level and mean corpuscular volume were lower than 12 mcg/L and 74 fL, respectively. [4]
8 months – 15 years
iron deficiency = 14%
iron deficiency anaemia = 2.9%
n=3100, Northern Greece, iron deficiency and iron deficiency anaemia [5]
Adults
Iron deficiency anaemia = 2.8-8.9/1000 person years
Netherlands, iron deficiency anaemia [6]
Women 40-70yrs
In 1984 pre-menopausal women median ferritin level = 43 mcg/L, post-menopausal women median ferritin level = 75 mcg/L
In 1994 pre-menopausal women median ferritin level = 39 mcg/L, post-menopausal women median ferritin level = 93 mcg/L
Small + depleted iron stores
Pre-menopausal women
1984 = 35.8%, 1994 = 41.0%
Post-menopausal women
1984 = 9.7%, 1994 = 7.4%
n=1221-1261, Denmark, 1983-1984 and 1993-1994, iron status depleted iron stores = ferritin < 16 mcg/L
small + depleted iron stores = ferritin ≤32 microg/L
iron deficiency anaemia = ferritin <13 microg/L and haemoglobin <5th percentile for iron replete women
[7]
Iron depletion concerns 10-30% of menstruating women and iron deficiency anaemia 1.5 to 14%.
In pregnant women, the prevalence of iron deficiency anaemia is 6 to 30%.
In children, the prevalence of depleted iron stores varies from 2 to 48% and anaemia from 2 to 4% according to age group and country. In adolescents, prevalences are respectively 5-43% and 7-8%.
In adult men, the prevalence of depleted iron stores varies from 0 to 3%.
Europe, iron deficiency [8]
