Material for the study served 181 adults skull from burial grounds north of Western Siberia VIII-XVI centuries. The manifestations of porotic hyperostosis have been recorded on the vault and in orbits (cribra orbitalia). Author suggested integrated index of porotic hyperostosis that takes into account both signs to better reflect anemia. Its prevalence in the studied population indicates that most of the medieval people had chronic mild or moderate anemia represented equally in both sexes. The study has found two complex reasons of the development of anemia: nutrition and sanitation. Nutritional reason proved unacceptable to explain chronic anemia due mainly fish diet of study population. The main role was played by the sanitary reason. It is assumed that its leading component was helmintic infestation of Opisthorchidae and Diphilobothrium latum. Differences in the manifestation of symptoms of anemia in nearby necropolis considered as a result of differentiation of social strata of medieval society. The observed increase in chronological porotic hyperostosis manifestations interpreted as growth of immune stress in the late Middle Ages. This could occur as a result of deteriorating living conditions due to the augmentation of the local density of population, bringing infections with inlargement external contacts, the possible increment in helminthes infection of fish.
