Influence of Working Memory on Academic Achievement and Quality of Life in Children with Beta-Thalassemia Major

摘要

Background:Children with beta-thalassemia major may suffer from working memory impairment. For a more refined understanding of this issue, we assessed working memory function in beta-thalassemia children and evaluated its influence on academic achievement and quality of life.Methods:This was a cross-sectional study involving 60 beta-thalassemia children aged 8-12 years. All participants underwent a working memory assessment using the digit span and were interviewed using academic achievement and Indonesian version of PedsQL 4.0 questionnaires. Working memory in beta-thalassemia children significantly influences their quality of life, both directly (β=0.32) and indirectly, through their academic achievement (β=0.639). Longer duration of transfusion (p=0.01) is significantly related to poorer working memory, while lower hemoglobin level (p=0.81) and higher ferritin level (p=0.24) are not significantly associated with working memory.Conclusion:We concluded that working memory influences the quality of life in beta-thalassemia children, both directly and indirectly, through their academic achievement.
