RESUMO
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.
