Multisectoral action to prevent noncommunicable diseases in Saint Lucia.

OBJECTIVE: Noncommunicable diseases (NCDs) account for approximately 80% of annual mortality in Saint Lucia, with the results of national World Health Organization (WHO) STEPwise approach to NCD risk factor surveillance surveys in 2012 and 2020 indicating increasing prevalences of hypertension, obesity and physical inactivity. In response, the Ministry of Health, Wellness and Nutrition launched the St. Lucia Moves Initiative in 2022, aligned with the Caribbean Moves framework and WHO's Global Action Plan for the Prevention and Control of Noncommunicable Diseases 2013-2030. This study aimed to evaluate the implementation, reach, and early outcomes of the Initiative. METHODS: A mixed-methods approach was used to assess program implementation and engagement. This approach combined quantitative and qualitative methods to provide a comprehensive understanding of the Initiative's reach, visibility and multisectoral integration. The study was guided by the socioecological model of health promotion, which informed both the analytical framework and the interpretation of findings across all levels. RESULTS: Key achievements included increased public awareness of physical activity and wellness, broad cross-sectoral participation, and widespread engagement in fitness walks, media campaigns, school-based activities, and integration of the St. Lucia Moves Initiative into national cultural events. Although at the beginning, awareness of the Initiative was limited, it evolved into a recognized national movement within 2 years, supported by collaboration among government, civil society and community groups. CONCLUSIONS: Implementation of the St. Lucia Moves Initiative demonstrates the potential of evidence-based, multisectoral strategies to address the growing burden of NCDs. The program highlights the importance of strong leadership, phased implementation and youth engagement in promoting behavior change. The Initiative provides a promising model for small island developing states seeking to implement coordinated, data-driven approaches to reduce NCD risk factors and improve population health.
