RESUMO
BACKGROUND: The issue of malnutrition in the Democratic Republic of Congo is severe. Meanwhile, the Water, Sanitation, and Hygiene program has been demonstrated to be effective in reducing the rates of growth stunting among children. OBJECTIVE: We aimed to explore the association between maternal exposure to mass media and stunting in children through water, sanitation, and hygiene behaviors. METHODS: Mediation analysis was conducted using data from the 2018 Multiple Indicators Cluster Surveys. RESULTS: Mothers' exposures to television and the internet in the Democratic Republic of Congo significantly decreases the risk of stunting in children by 5% and 10%, respectively, mediated by household water, sanitation, and hygiene facilities and practices. CONCLUSIONS: These findings could inform interventions and policies to reduce the rate of stunting rate children by promoting water, sanitation, and hygiene through mass media, especially through the internet and television.
