title: [Lactase deficiency in aboriginal inhabitants of the Mordovian and Karelian ASSR].
abstract: The aim of the work was to examine the validity of the cultural-historical hypothesis about the origin of lactase deficiency in adults on an example of the populations of the Finno-Ugric group. Examination included 692 healthy subjects aged 20-50 years. It was established that the incidence of lactase deficiency among relevant ethnic groups was identical. The data obtained support the validity of the cultural-historical hypothesis about lactase deficiency (selective lactase malabsorption).
