Abstract
Introduction: Under nutrition continues to be a major problem among children in Ethiopia. There are factors that directly or indirectly influence a nutritional status of children including food insecurity. Amongst others, proper infant and young child feeding practice is crucial for development, growth and nutritional status of children. However, there is a scanty of information on factors influencing mother’s care giving behaviors and role of appropriate infant and child feeding practice on nutritional status of children in Ethiopia. Thus, this study aimed to identify factors influencing appropriate infant and young child feeding practice and evaluate its effect on nutritional status of children age group of 6-23 months in Ethiopia.
Methods: This study used data from Ethiopia Demographic Health survey, 2011. This study employed propensity score matching method to estimate the impact of infant and child feeding practice on nutritional status. Logit regression analysis was used to identify factors influencing infant and young child feeding practice. A series of tests was conducted related to variable choice of the propensity score specification, quality of matching and robustness checks. Mantel-Haenszel bounds was used to check sensitivity of estimated treatment effects on the treated to hidden bias in order to validate the propensity score matching analysis.
Results: A proportion of infants and children received appropriate feeding practice found to be very small (3%). Maternal educational status, place of residence, maternal exposure to media, being male headed household and being married/living with partners were associated with appropriate feeding practice of children age group 6-23 months. Also, a propensity score matching revealed that a significant effect of good infant and child feeding practice in reducing stunting by around 19% among children aged 6-23 months.
Conclusion: Maternal educational status, place of residence, maternal exposure to media, being male headed household and being married/living with partners are important factors influencing appropriate feeding practice of children age group 6-23 months. Good infant and child feeding practice has a positive and significant effect in decreasing stunting among children 6-23 months but should be interpreted with a caution due to the presence of unobserved heterogeneity.
