Trends and determinants of child stunting in Ethiopia: a longitudinal analysis of sociodemographic factors and regional disparities.

Stunting remains a critical issue affecting child health in Ethiopia, with significant implications for growth and development. Despite efforts to address stunting, understanding its determinants and trends over time is essential for developing effective interventions. The objective of this study is to examine the trends and determinants of child stunting in Ethiopia, focusing on sociodemographic factors and regional disparities. This longitudinal observational study utilized data from the Young Lives project covering the period from 2002 to 2016. An ordinal logistic regression model with generalized estimating equation (GEE) was used to analyse 7,680 observations from 1,536 children across Ethiopia. Variables included sociodemographic factors, access to resources, and parental education levels. Over the study period, there were notable improvements in child stunting rates, influenced by variables such as household wealth, maternal education, access to safe drinking water, and urban versus rural residence. Children in households with higher wealth and maternal education levels experienced lower rates of stunting. Regional disparities were evident, with a greater prevalence in Amhara and lower rates in Addis Ababa.The findings underscore the importance of targeted interventions to address socioeconomic disparities and improve resource access. Enhancing maternal education, ensuring access to safe water, and addressing regional disparities are critical to reducing child stunting rates in Ethiopia.
