Early detection of anemia among school children using the World Health Organization Hemoglobin Color Scale 2006
Keywords:

Abstract
Background The high prevalence of anemic children in Indonesiais caused by the high incidence of diseases caused by parasitic
infection such as malaria as well as iron deficiency. Early detection
is needed for early intervention in order to allow optimal growth
and development. A simple, economic, and practical tool for
early detection of anaemic children is needed. The WHO
recommended a Hemoglobin Color Scale as a suitable tool for
the detection of anemia.
Objective To assess the sensitivity, specificity, and predictive
values of the WHO Hemoglobin Color Scale for early detection
of anemic children.
Methods A cross sectional diagnostic test was conducted in
elementary school age children. Samples consisting of two drops of
venous blood on paper were assessed by two observers (pediatrician
& paramedic) using the Hemoglobin Color Scale to visually
determine the level of hemoglobin. In addition, the hemoglobin
level was also measured using a Hematology Analyzer to allow the
visual test results to be compared to the results obtained using the
gold standard of analysis. Agreement between these two methods
of analysis was examined using the Cohen's kappa.
Results Hemoglobin levels < 11.5 g/dL were detected in 15 of
124 (12%) elementary school children. The sensitivity, specificity,
positive and negative predictive values when using the Hemoglobin
Color Scale were 93%, 100%, 100% and 99% respectively for the
first observer and 100%,99%,93%, and 100% respectively for the
second observer. The Cohen's Kappa value was 0. 76.
Conclusion The WHO Hemoglobin Color Scale 2006 could
be used as an early detection method for anemia in children.
