Abstract
Chronic diseases, also known as non-communicable diseases (NCD) are one of the most important public health problems of our time. Many of these diseases can be reduced by achieving healthy lifestyles. Community interventions are very useful in reducing these types of diseases since they have a direct impact over daily conditions and are adjustable to the complex situations that they carry. This article describes the process of the creation of a collaborative platform for the design and implementation of community interventions to prevent NCDs. This platform includes six non-governmental organizations who have aligned their prevention and health promotion objectives to develop joint community interventions. The intervention levels approach, based on the socio-ecological model has been the basic model to structure the working groups of the platform. Dealing with institutional differences, complexity and variability of contexts, defining the roles and responsibilities and managing the resources are key elements to have in mind to achieve good relations and functional partnerships to design and implement effective community interventions at different levels. Institutional recognition, support and planning based on local priorities are also key elements for these kinds of platforms to be successful, sustainable and, therefore, have an impact on people's health.
