Abstract
OBJECTIVE: Indigenous Australians have poorer health outcomes compared to the non-Indigenous population. Malnutrition, and subsequently iron-deficiency anaemia, impairs childhood development. The aim of this study was to identify the prevalence of anaemia in school-aged children of an Australian Indigenous community and evaluate the effectiveness of treatment. DESIGN: A retrospective cohort study. SETTING: A Northern Territory Indigenous community. PARTICIPANTS: Two hundred and one school-age students (5-15 years old) undergoing annual school screening. MAIN OUTCOME MEASURES: Presence of anaemia. Anaemic and non-anaemic students were compared to determine any differences in age, gender, BMI and past history of anaemia. The response to treatment was analysed using initial and repeat haemoglobin results. RESULTS: Altogether, 201 students were screened with 105 (52%) classified as anaemic. No significant association was found between anaemic students and age, gender, BMI or prior history of anaemia. After treatment, the mean rise in haemoglobin was 13% (95% CI 11-15) at the 4-week interval. Age (P = 0.17), gender (P = 0.53) and weight (P = 0.14) were not significantly associated with treatment efficacy. Only 11 students (17%) were still anaemic after treatment. DISCUSSION: Anaemia in Indigenous Australian school-aged children is a major public health issue. The prevalence of anaemia in this population is 52% and many times higher than that of the general Australian population. As per current guidelines, the recommended treatment is effective in over 80% at the 4-week interval. Community wide interventions are required to combat this alarming issue.
