Iron status and prevalence of anaemia among school children in the Jaffna district

Abstract

Introduction: The National Nutrition and Micronutrient Survey of 2012 reported that anaemia was seen in 15% of Sri Lankan children between 6 months and 5 years of age. Objectives: To identify the prevalence of anaemia and the impact of the intervention programmes among 6-16 year old children in the Jaffna District. Method: A community based cross sectional study was carried out using multistage stratified proportionate cluster sampling technique among children attending schools in the Jaffna district. A pre-tested questionnaire was used to collect data and a blood sample was obtained for serum ferritin and HS-CRP levels. Haemoglobin was checked using the Haemacue apparatus on the spot. WHO definitions and cut off values were used. Results: A total of 1163 school students between 6-16 years were screened (male: female ratio 1:1.02). Mean age was 12.33 ±3.1 years. Mean haemoglobin was 12.31±1.51g/dl and mean serum ferritin was 21.31ng/ml 95%CI 18.99-23.63 respectively. The prevalence of anaemia was 27.9% (n=324), prevalence of iron deficiency anaemia was 16.8. Females had higher prevalence (30.6%) of anaemia when compared to males (25%) (p<0.01). Prevalence of iron deficiency was 52% adjusted after excluding population with high CRP.
