Assessment of Hemoglobin, Iron and Copper in Adolescents of Urban School.
Anemia is a health problem among adolescents because the requirements for energy and nutrients including essential trace elements are higher than adult. It is often associated with a decrease in some trace elements (iron, zinc & copper) and an increase in heavy metals as lead.
Due to increased requirements for iron and zinc to meet the increased demand for erythropoiesis as well as high growth rate, the level of zinc and copper have important role in the development of iron deficiency.
Objectives: To correlate serum Iron and copper level in anemic and non anemic adolescents.
Materials and Methods:
Total 100 students were included in the study and blood samples were collected from all the participants were tested for hemoglobin level, serum iron and copper level.
All statistical calculations were done by independent sample t-Test and bivariate correlation analysis.
The mean serum iron level in anaemic subjects was low compare to mean serum iron level of non-anaemic subjects and it was statistically significant (p<0.001). The mean serum copper level in anaemic subjects was high compare to mean serum copper level in non-anaemic subjects and it was also statistically significant (p<0.001).
Serum copper level was found to be significantly high in anemic adolescents with low iron level. This increased copper concentration may occur due to bioavailability of copper is more than iron, at the same time both copper and iron use same transport protein competitively, which causes decrease iron absorption and it leads to increase copper absorption. Thereby decrease haemoglobin synthesis and cause anaemia. Haemoglobin level might be controlled by supplementing iron and steps should be taken to reduce anaemia in adolescents.
