The basic parameters of physical development were studied in 220 children of preschool age with either decreased (below 10 pc) and normal values of the arterial blood pressure (ABP) according to regional normatives. The mean values of indexes of weight and height for the children of both groups depending on the indexes of ABP were obtained. Hypotensive children had low height indexes (P<0,001) — (13.1±3.8) and (14.2±1.7) % accordingly as compared to normotensive children, more frequently they had disharmonious physical development with the weight deficit in relation to height (31.2±5.3) % against (23.1±3.5) % in normotensive children), more frequent the extremely low body mass indexes were marked — in 23.4 % against 19.6 % in normotensive children had the average physical development.
