RESUMEN
BACKGROUND: In most developing countries, addressing malnutrition involves a coalition of stakeholders that includes the government and international development partners. This study explores the evolution of the malnutrition actor coalition landscape before and after the emergence of the National Nutrition Policy in the Lao People's Democratic Republic (Lao PDR) in 2008. METHODS: A qualitative study was conducted based on the theory of coalition structuring. Twenty semi-structured interviews were performed with representatives of national and international organisations involved in addressing malnutrition in Lao PDR. The information obtained from the interviews was complemented by an analysis of relevant documents dating back to 1990. Interviews were recorded and transcribed verbatim. A thematic analysis was performed using NVivo 11 software and the diagrams of collaboration drawn by the participants were turned into a visual collaboration map using SocNetV software. We relied on various types of triangulation to increase the analysis's credibility, reliability, and confirmability. RESULTS: The results showed that before the emergence of the National Nutrition Policy, three coalitions representing the health, agriculture, and education sectors coexisted. These colalitions worked largely in silos, although with some interactions when deemed necessary mainly by United Nations agencies. The emergence of the National Nutrition Policy provided the government with an effective political tool for coalescing the three coalitions into a unique coalition involving all major stakeholders in the nutrition field. All three forces that incite actors to collaborate inside a coalition according to the theory of coalition structuring (transactions, control, intangible factors) were mobilised in the creation of the single coalition. CONCLUSIONS: Combating malnutrition is a government priority in the Lao PDR. The current study showed that the National Nutrition Policy in Lao PDR has led to a significant evolution in the malnutrition coalition landscape, resulting in improved collaboration among stakeholders. This finding highlights the effectiveness of public policies in facilitating intersectoral activities to tackle complex problems, such as malnutrition.
