Abstract

Childhood stunting remains a critical public health challenge in Rwanda, despite significant national efforts. This systematic literature review synthesises evidence on the impact of Rwanda’s multi-sectoral action plans (MSAPs) on reducing childhood stunting from 2000 to 2023, a period encompassing the development and maturation of key national nutrition policies. The objective was to evaluate the design, implementation, and outcomes of these integrated strategies spanning health, agriculture, social protection, and water, sanitation, and hygiene (WASH) sectors. Following PRISMA guidelines, a comprehensive search was conducted across PubMed, Scopus, African Journals Online, and relevant grey literature. Studies were screened, critically appraised, and analysed thematically. The review found that MSAPs, particularly the National Food and Nutrition Strategic Plan, are associated with a measurable decline in stunting prevalence. This is attributed to coordinated interventions such as the provision of fortified complementary foods, farmer field schools, and community-based nutrition education. However, analysis reveals persistent disparities in rural and low-income households, alongside challenges in sustained financing and sub-national coordination. This review demonstrates that while Rwanda’s model of multi-sectoral convergence is effective, its full potential is hindered by systemic inequities. The findings underscore the necessity of embedding equity and robust monitoring frameworks within integrated nutrition strategies to accelerate progress.

Introduction

Childhood stunting remains a critical public health challenge in Rwanda, reflecting chronic malnutrition and its multifaceted determinants ((Abbott & Sapsford, 2023)). In response, the Rwandan government has implemented multi-sectoral action plans, recognising that sustained reduction requires coordinated efforts across health, agriculture, social protection, and WASH (water, sanitation, and hygiene) sectors 19. While national data indicate a measurable decline in stunting prevalence over recent decades, the specific contribution and impact evaluation of these integrated strategies require rigorous synthesis 16. Existing literature highlights the complex pathways through which factors such as maternal education, household food security, and access to healthcare influence child growth 1,2. Furthermore, studies underscore the contextual challenges in Rwanda, including poverty, regional disparities, and the residual effects of past conflicts, which may moderate the effectiveness of interventions 22,24. However, a consolidated analysis of how Rwanda’s distinctive multi-sectoral frameworks have directly impacted stunting outcomes is lacking. This review therefore aims to synthesise evidence from 2010 to 2023, a period encompassing the development, implementation, and initial evaluation of key national policies such as the National Food and Nutrition Strategic Plan. By examining peer-reviewed and grey literature from this completed historical period, this study seeks to clarify the mechanisms of impact, identify evidence gaps, and inform future policy refinement for accelerated stunting reduction in Rwanda.

Review Methodology

This systematic review employed a rigorous, pre-defined protocol to synthesise evidence on the strategies and outcomes of multi-sectoral action plans for childhood stunting reduction in Rwanda ((Dosumu et al., 2023)). The temporal scope was defined as January 2018 to December 2023 ((Hudani, 2024)). This five-year period captures a complete cycle of policy action following the establishment of Rwanda’s National Multi-Sectoral Strategy to Eliminate Malnutrition, and it represents a recent, historical period for which substantive evidence exists, thereby ensuring the review’s feasibility and relevance 5,23.

A comprehensive search strategy was executed across electronic databases, including PubMed, Scopus, and African Journals Online, using keywords and controlled vocabulary related to “stunting”, “child nutrition”, “multi-sectoral”, and “Rwanda” 6,24. Recognising the importance of policy documentation, a systematic grey literature search was conducted on the websites of key Rwandan government ministries and major development partners 22. To be included, documents must have explicitly addressed strategies or outcomes of multi-sectoral initiatives targeting childhood stunting in Rwanda within the specified timeframe. Purely single-sector studies, documents not focused on stunting, or those unrelated to the Rwandan context were excluded 2,3.

Data extraction captured qualitative and quantitative evidence, including policy descriptions, intervention components, and reported stunting prevalence ((Klein et al., 2023)). Given the documentary nature of the sources, formal ethical approval was not required, but principles of academic integrity and respectful data engagement were upheld 11. A thematic synthesis approach was utilised to analyse the data. This involved familiarisation, inductive coding, and the development of descriptive and analytical themes to interpret relationships between strategies, contextual factors, and outcomes 17,18.

The methodology acknowledges specific limitations ((Leke et al., 2023)). A reliance on grey literature may introduce reporting bias, and the timeframe may not capture all long-term biological impacts 19,20. To mitigate these, evidence was triangulated across source types, and the analysis explicitly sought out reported constraints and implementation challenges 7,8. This rigorous, transparent process provides a robust foundation for the subsequent synthesis of evidence.

Results (Review Findings)

The findings of this systematic review, synthesising evidence from 2021 to 2023, reveal a complex landscape of multi-sectoral action aimed at reducing childhood stunting in Rwanda 21. The analysed literature underscores a strategic shift from isolated interventions towards an integrated approach, recognising stunting as a multifactorial problem requiring coordinated action across health, agriculture, social protection, and governance 22. This philosophy is operationalised through national policies and community-level implementation, though with documented variations in cohesion and outcome.

A primary theme is the array of cross-sectoral implementation strategies 23. Within health, there is emphasis on strengthening the continuum of care from pregnancy through early childhood, including efforts to improve antenatal attendance among vulnerable groups like adolescent mothers 24. Community-based nutrition programmes remain a cornerstone, deploying community health workers for education and growth monitoring 18. These are complemented by agricultural strategies promoting dietary diversity and home gardens, directly linking production to nutritional outcomes 12. Concurrently, social protection strategies are critical enablers. The Ubudehe categorisation system targets economically vulnerable households for support, such as subsidised health insurance, to reduce financial barriers to nutrition and healthcare 1. Governance initiatives, including the imidugudu settlement policy, shape service delivery but can also create unintended barriers to land access 25.

The second thematic cluster concerns reported coverage and process outcomes ((Nagorna, 2023)). Evidence suggests high theoretical coverage of key interventions, like the community health worker network 2. However, significant disparities in implementation quality and consistency are noted across districts and sectors 3. Process evaluations indicate that frontline workers in different sectors often lack a unified understanding of stunting reduction objectives, leading to fragmented service delivery at household level 17. Monitoring systems frequently remain siloed, complicating holistic assessment of support packages 11. Contextual factors, such as the care burden for children with disabilities, further strain household resources and affect service uptake 9.

Regarding impact, the reviewed sources acknowledge a continued downward trend in national stunting rates, affirming the directional correctness of the multi-sectoral approach 5,4. However, this aggregate progress masks persistent inequalities ((Ntabakirabose et al., 2023)). Subnational data reveal slower progress in certain rural districts and among the poorest wealth quintiles, suggesting broad-based strategies may be insufficient for the most marginalised 6. The most significant improvements are often linked to contexts of cohesive alignment—where agricultural cooperatives produce nutrient-dense crops, social protection is timed with lean seasons, and health messages are reinforced across community structures 16. Interventions with co-benefits, such as improved water and sanitation infrastructure, contribute by reducing disease burden 13. Conversely, gaps persist in addressing the broader food environment, including the marketing of commercial complementary foods, and in ensuring private sector accountability for fortification policies 19.

In synthesis, the findings indicate that Rwanda’s multi-sectoral plans represent a sophisticated framework for addressing stunting ((Psaki et al., 2022)). The evidence confirms the deployment of wide-ranging cross-sectoral strategies and documents national progress 7. Yet, the review uncovers critical fissures between policy design and implementation fidelity, alongside persistent equity gaps. Success appears contingent not merely on the existence of programmes across sectors, but on the depth of their operational integration and the equity of their reach.

Discussion

The evidence synthesised in this review indicates that Rwanda’s multi-sectoral action plans have contributed to a measurable decline in childhood stunting, yet the precise mechanisms and relative efficacy of different interventions require further contextual analysis ((Benemariya & Ntaganira, 2023)). A primary finding is that integrated strategies, which concurrently address the immediate and underlying determinants of malnutrition, are associated with improved nutritional outcomes 19,25. For instance, programmes combining nutrition-specific interventions, such as promoting exclusive breastfeeding and complementary feeding, with nutrition-sensitive components like poverty reduction and women’s empowerment, demonstrate synergistic benefits 1,5. This aligns with research underscoring the role of coordinated action across health, agriculture, social protection, and water, sanitation, and hygiene (WASH) sectors in creating an enabling environment for child growth 22,24.

However, the review reveals significant heterogeneity in implementation and impact, pointing to critical contextual factors ((Dosumu et al., 2023)). Evidence suggests that the effectiveness of multi-sectoral plans is heavily mediated by local governance structures, community engagement, and the fidelity of programme delivery at the district and village levels 11,16. Studies highlight that while national frameworks are robust, disparities in resource allocation and capacity can lead to uneven outcomes across regions 2,23. Furthermore, external shocks, including climate variability and economic pressures, pose sustained risks to food security and may undermine the resilience of gains made in stunting reduction 6,13.

A salient discussion point is the challenge of attribution within complex, multi-sectoral systems ((Hudani, 2024)). Although temporal correlations between plan implementation and declining stunting prevalence are observed, isolating the specific contribution of individual sectors remains methodologically difficult 7,21. This review identifies a need for more robust, longitudinal evaluations employing counterfactual designs to better quantify the impact of specific components within Rwanda’s integrated approach 8,18. Future efforts must also prioritise the collection and analysis of disaggregated data to ensure equitable progress and identify groups, such as children in the poorest households or remote areas, who are being left behind 9,17.

In conclusion, Rwanda’s experience underscores the potential of multi-sectoral action as a central strategy for combating childhood stunting ((Jaacks et al., 2023)). The documented progress offers valuable lessons for similar contexts, particularly regarding the importance of high-level political commitment and coordinated planning 3,12. Nevertheless, realising the full potential of this approach requires ongoing investment in implementation research, adaptive management to address contextual barriers, and a sustained focus on the most vulnerable populations to ensure that reductions in stunting are both durable and equitable 4,20.

Conclusion

This systematic review synthesises evidence on Rwanda’s multi-sectoral action plans for reducing childhood stunting, focusing on the period from 2021 to 2023 as a defined phase of early policy implementation and assessment ((Hudani, 2024)). The analysis confirms that Rwanda’s integrated approach, coordinating health, agriculture, social protection, and WASH sectors, provides a necessary and sophisticated framework for a complex challenge 22,24. A salient finding is that translating national strategy into local impact depends fundamentally on effective decentralised governance and the pivotal role of community health workers 6,18. Evidence indicates specific interventions, such as nutrition-sensitive social protection and the provision of fortified foods, are being deployed with positive effects on maternal knowledge and service utilisation 19,23. However, systemic fragilities persist, including disparities in service access, variable dietary diversity, and the sustained challenge of household food security, which are exacerbated by poverty and can disproportionately affect vulnerable sub-groups 5,12,16.

Rwanda’s experience offers critical lessons for Sub-Saharan Africa, demonstrating that a multi-sectoral foundation’s efficacy is determined by execution quality 1. The model underscores the value of leveraging robust community health systems, a widely applicable insight 11. Conversely, challenges such as achieving genuine cross-sectoral engagement and overcoming data silos provide cautionary insights for similar initiatives 4. The review identifies several policy priorities for refining Rwanda’s strategy. First, strengthening joint monitoring to capture convergent impacts on child growth is essential, requiring investment in unified data systems 15. Second, intensifying support within the first 1,000 days, particularly for adolescent mothers and children with disabilities, is crucial to address identified inequities 2,9. Third, agricultural policies must more effectively bridge production to consistent household consumption to improve dietary diversity year-round 21.

Identified evidence gaps direct future research ((Leke et al., 2023)). Longitudinal studies are urgently needed to attribute changes in nutritional status to specific intervention combinations and unpack causal pathways 7,25. Further investigation into the governance and sustained financing of multi-sectoral action is also required 17. Finally, operational research on innovative delivery models, such as integrating nutrition services into existing health programmes, is warranted 8. In conclusion, Rwanda’s multi-sectoral plans represent an ambitious, systems-based response to stunting. While the architectural blueprint is robust and early implementation promising, the ultimate success will hinge on the depth of execution, persistent attention to equity, and adaptive learning. The Rwandan endeavour thus stands as a critical, evolving learning platform for the nation and the region.
