Abstract

Background: Anemia among school aged children is known to be an important global public health problem in both developing and developed countries. It affects the physical and intellectual functions of the affected children. School years are ideal opportune time to intervene to prevent and control anemia. Objectives: The objective of the study is to investigate the frequency of anemia and the associated dietary and medical risk factors in school aged children in Riyadh region. Subject and Methods: A cross sectional survey was carried out in Riyadh region. The study sample was selected using the two stages of cluster sampling technique. Standardized Arabic questionnaire was completed by parents of school aged children by two well trained nurses. Dietary frequency was requested for the last week prior to the interview. A venous blood sample was taken for hemoglobin estimation. Anemia in school aged children was defined according to the WHO definition. Results: The total sample was 1117 children, 49.9% males and 50.1% females. Prevalence of anemia was 22.3% (22.4% in males & 22.2% in females). Frequent eating of red meat reduced the risk of anemia (OR=0.8). Frequent drinking of cola or sour milk (Laban) with lunch meal significantly increased the risk of anemia (OR=1.52, 1.06-2.16 and OR=1.55, 1.07-2.25 respectively). Family history of hereditary blood disorders or iron deficiency anemia increased the risk of anemia in school aged children (OR=5.48, 1.02-31.21 and OR= 3.38, 1.74-6.54 respectively). Conclusions: Anemia in school children is a moderate public health problem in Riyadh region. Drinking sour milk with lunch and positive family history increases the risk of anemia in school children.
