Academic achievement of elementary school-aged children with pre-anemic iron-deficiency
Abstract
Background Relationship between iron deficiency andcognitive function has been investigated in many studies, but
they usually focused on iron deficiency anemia. Brain iron
storage might have already decreased before anemia exist.
Objectives To investigate the prevalence of pre-anemic irondeficiency
in school-aged children and to determine whether
this condition is a risk factor for low academic achievement.
Methods A cross-sectional study was conducted on 87 subjects
of znd,6th grade in SDN 04 Petang, Kramat, Senen, Jakarta
on August 2008. The subjects underwent peripheral blood
and ferritin serum concentration examinations. Twentynine
subjects who suffered from anemia were excluded. The
remaining 58 subjects were classified into normal body iron
status group and preanemic iron-deficiency group.
Results The prevalence of pre-anemic iron-deficiency in SDN
04 Petang, Kramat was 6%. The prevalence ratio to determine
whether pre-anemic iron-deficiency was a risk factor for low
academic achievement could not be calculated because the
minimal sample number required was not reached. There was
no relationship between pre-anemic iron-deficiency and low
academic achievement for mathematics, Indonesian language,
science, and social science.
Conclusions The prevalence of pre-anemic iron-deficiency in
SDN 04 Petang, Kramat Senen Jakarta was 6%. This study
is not able to determine whether pre-anemic iron-deficiency
is a risk factor for low academic achievement in school-aged
children; therefore further study with more efforts to detect
the presence of iron deficiency in children with inflammation
is needed.
