Insights
Childhood anaemia remains high in low-income countries, causing cognitive deficits and mortality. Key factors include maternal anaemia, poverty, and low birth weight, highlighting the need for improved nutrition and maternal education.
Area of Science:
- Global Health
- Pediatrics
- Nutritional Epidemiology
Background:
- High prevalence of anaemia in infancy in low and lower-middle-income countries.
- Anaemia in early childhood leads to irreversible cognitive deficits and increased child mortality.
- Childhood anaemia perpetuates poverty cycles.
Purpose of the Study:
- To analyze factors associated with anaemia in children aged 6-23 months using a multi-level approach.
- To identify determinants of anaemia in young children in low-income settings.
- To inform interventions for anaemia prevention in vulnerable populations.
Main Methods:
- Utilized data from 52 Standard Demographic Health Surveys (S-DHS) between 2005-2015.
- Employed traditional and multilevel logistic regression analyses.
- Examined associations between haemoglobin levels and household, child, maternal, and socio-demographic variables.
Main Results:
- 70% of children aged 6-23 months in the sample were anaemic.
- Strong associations found between child anaemia and maternal anaemia, household wealth, maternal education, and low birth weight.
- Consumption of fortified foods, potatoes, and tubers correlated with lower anaemia rates.
Conclusions:
- Improving household living conditions and maternal education are crucial for reducing anaemia.
- Timely introduction of iron-rich foods at six months is recommended.
- Strategies should focus on maternal health, nutrition, and socio-economic factors to combat childhood anaemia.
Abstract:
In Low and Lower-Middle-Income countries, the prevalence of anaemia in infancy remains high. In early childhood anaemia cause irreversible cognitive deficits and represents a higher risk of child mortality. The consequences of anaemia in infancy are a major barrier to overcome poverty traps. The aim of this study was to analyse, based on a multi-level approach, different factors associated with anaemia in children 6⁻23 months old based on recent available Standard Demographic Health Surveys (S-DHS). We identified 52 S-DHS that had complete information in all covariates of interest in our analysis between 2005 and 2015. We performed traditional logistic regressions and multilevel logistic regression analyses to study the association between haemoglobin concentrations and household, child, maternal, socio-demographic variables. In our sample, 70% of the 6⁻23 months-old children were anaemic. Child anaemia was strongly associated with maternal anaemia, household wealth, maternal education and low birth weight. Children fed with fortified foods, potatoes and other tubers had significantly lower rates of anaemia. Improving overall household living conditions, increasing maternal education, delaying childbearing and introducing iron rich foods at six months of age may reduce the likelihood of anaemia in toddlerhood.
