Prevalence of, and factors associated with anaemia in children aged 1-3 years in Aceh, Indonesia: A cross-sectional study.

ABSTRACT

Background: Child anaemia continues to represent a major public health challenge in lower-and-middle income countries. It has serious long-term consequences for child growth and development. In Indonesia, there was a 10% increase in the national prevalence of child anaemia between 2013 and 2018. Aim: This study aims to assess the prevalence of, and factors associated with anaemia among children aged one to three years in eight districts in Aceh Province, Indonesia. Methods: A cross-sectional study was conducted on a sample of 1148 mother-child dyads aged one to three years between November and December 2018. The sampling process involved a three-stage cluster sampling design using the probability proportionate to size methodology. Anaemia status was determined using haemoglobin level (Hb < 11.0 g/dL). Data were analysed using multivariable logistic regression to estimate adjusted odds ratios (aOR) and their 95% confidence intervals (95% CI) for associated factors. Results: The overall prevalence of anaemia was 76.1% (869/1142). 44.7% (510/1142) and 28.6% (327/1142) had moderate and mild anaemia, respectively. Child aged 12-24 months (aOR 2.00, 95% CI 1.26-3.17), not receiving routine immunisation (aOR 2.62, 95% CI 1.34-5.10), and maternal anaemia (aOR 2.15, 95% CI 1.59-2.90) were significantly associated with anaemia. Conclusion: The prevalence of anaemia among the children in this study was high, and was associated with child age, immunisation status, and maternal anaemia. These findings provide further insight into anaemia as a public health issue at a sub-national level in Indonesia and for development of targeted programmes to address associated risk factors of child anaemia.
