Hemoglobin serum levels in adolescents according to sexual maturation stage

| Sumario: | During adolescence, the risk of development of iron-deficiency anemia is higher because of the growth spurt and the sexual maturation which increase the iron requirement. One hundred and thirty adolescents (males and females) were studied, in order to assess the serum hemoglobin values in different sexual maturation stages. The photometric method was used and a self-evaluation of the sexual maturation stage based on Tanner´s criteria was applied. The average hemoglobin values were similar for both sexes, as well for girls who had menstruated or not. The average hemoglobin values were 13.3 (s.d. 1.12)g/dL for males and 13.3 (s.d.0.83)g/dL for females (p=0.64). Among the studied adolescents, 7.7% had iron-deficiency anemia. Due to the iron requirement increase during the growth spurt, mainly in females, and the higher susceptibility to iron deficiency anemia, special attention to the adolescents is recommended. |
