摘要:In the rapidly progressing world where different sectors become more interconnected, cross-sectoral cooperation in health promotion lacks a specific set of instruments, navigating partners through the cooperation process in project implementation. Cross-sectoral cooperation is an everyday practice in business and has become an integral part of promoting health and wellbeing comprehensively and sustainably. In this paper, we propose a developed Model for cross-sectoral cooperation, which has been designed within the Interreg Baltic Sea Region project “Urban Labs for Better Health for All in the Baltic Sea Region” (Healthy Boost), aiming to boost cross-sectoral cooperation for health and wellbeing in cities and municipalities. The Model is developed based on literature research and self-assessment of cross-sectoral cooperation for health promotion in Healthy Boost partner cities and municipalities in Latvia, Poland, Russia, Finland, Estonia, Lithuania, and Sweden. Composed of five major domains (risk identification, leadership, coordination, communication, and motivation) and four stages of cooperation (mapping, planning, implementation, and assessment), it provides a checklist of helpful questions for identifying solutions effectively and systematically. The Model can be used both as a navigational tool and as an “emergency” tool to manage cross-sectoral cooperation challenges successfully.
