BACKGROUND: Concurrent anaemia and stunting (CAS) pose severe public health risks in low- and middle-income countries, affecting child health and development. OBJECTIVES: To determine trends in CAS prevalence and associated factors among infants and young children aged 6-23 months in Rwanda. METHODS: Analyses of nationally representative samples from the Rwanda Demographic and Health Surveys (RDHS) of 2010, 2014/15, and 2019/20 were conducted. Participants' characteristics, trends, and prevalence of CAS were analysed using frequencies and percentages. Multivariable binary logistic regression analyses were used to assess factors associated with CAS. RESULTS: The prevalence of CAS among children aged 6-23 months in Rwanda declined from 21.3% in 2010 to 16.9% in 2019/20 ( CONCLUSIONS: This study reveals persistent CAS among infants and young children in Rwanda. CAS was associated with various child, maternal, and household-related factors. Despite a notable decline in CAS prevalence in Rwanda over the past decade, CAS remains a significant public health issue, requiring targeted interventions.
