[Age-related characteristics of hemoglobin and erythrocytes in 7- to 17-year-old pupils].

A total of 1100 students, aged from 7 to 17 (50 boys and 50 girls from each age group) were covered wigh the study. The following indices were studied: hemoglobin concentration in blood and erythrocyte count. The results reveal that the average values of hemoglobin and erythrocytes in the boys and girls, aged from 7 to 17, are similar and gradually grow with age. Considerably higher values were found in the boys within the age period 14-17. Our results of hemoglobin of the students, aged 7-17, are lower then those of the foreign authors. The same lower values were established (according to literature data) about the adult population in our country, necessitating additional studies and elucidation of that fact.
