[Preschool children's functional status in relation to the sanitary-and-hygienic well-being of a children's educational establishment].

The functional status of preschool children was studied in relation to the sanitary-and-hygienic well-being, by evaluating the functional status of the cardiovascular and central nervous systems. Under poor sanitary-and-hygienic well-being, the children were ascertained to have lower indices of the cardiovascular and central nervous systems than those under satisfactory sanitary-and-hygienic well-being.
