The Climate change exacerbates people’s access to nutritious food and the risk of malnutrition, especially for vulnerable groups. West Sumatra’s stunting rate in 2022 is above the national average. It is necessary to know the factors that influence malnutrition. The study uses primary data with a questionnaire on heads of farmer and fisher families in areas vulnerable to climate change in West Sumatra, Indonesia, in 2024. We took a probability proportionate size sample of 305 and analysed it using Structural Equation Modelling with Partial Least Squares. The results showed a malnutrition incidence of 76.4%. Environmental health directly influenced infectious diseases, which in turn affected malnutrition, resulting in a large total effect of 0.113 (11.3%). Environmental health indirectly impacts malnutrition through disease, resulting in a substantial total effect of 0.309 (30.9%). Adaptation had a direct effect on malnutrition and a large total effect of 0.197 (19.7%). Dietary patterns do not have a significant effect on malnutrition. Adaptation to change includes reducing the incidence of infectious diseases and improving access to sanitation. We need adaptation strategies to enhance environmental health and manage infectious diseases. © 2026, Universitas Negeri Semarang. All rights reserved.
