[The frequency of infant anemia].

In the group of 391 examined children in the third trimester of their life the mean values have been established for the principal hematological parameters of the red family (hemoglobin = 11,52 +/- 0,87 g/100 ml, hematocrit = 36,12 +/- +/- 3,12%), as well as anemia frequency which is 29,06% if the lower lewel of the normal hemoglobin value is 11 g/100 ml for that period of infants' life. These investigations have been stated statistically significant lower hemoglobin values and a higher anemia frequency in group of infants with low weight at birth (17,5 of anemic children were prematurely born, and 55,38% weighted under 3.250 g. at their birth), than in the group of infants with non-adequate nutrition, and among infants with frequent infections. The prophylactic measures were suggested to decrease frequency of sideropenic anemia - the most widely spread type of anemia in early life of children.
