Prevalence and Types of Anemia in a Large Refugee Cohort in Western Europe in 2015.

Currently, vast numbers of migrants with largely unknown health statuses have been entering Europe. To improve care taking strategies, prevalence, severity and types of anemia in a large refugee cohort were assessed. Blood counts were performed in n = 787 inhabitants from six German refugee centers. Most included migrants were young, male adults. Anemia was present in 22.5% of subjects with an age-dependent prevalence increase (7.9% > 18 years vs. 30.8% > 50 years). More females than males were anemic (27.1% vs. 20.4%). The majority of affected migrants had mild anemia (86.2%) of either normocytic/normochromic (55.9%) or microcytic/hypochromic (20.9%) type. Observed anemia frequencies are in accordance with global anemia prevalence recently estimated by the WHO. However, the observed high rates of anemia particularly in female and older refugees emphasize the need for adapted care taking strategies in refugee medicine. Further evaluation of causes of anemia in the migrating population is needed.
