The burden of chronic disease in Europe continues to grow. A major challenge facing national governments is how to tackle the risk factors of sedentary lifestyle, alcohol abuse, smoking, and unhealthy diet. These factors are complex and necessitate intersectoral collaboration to strengthen health promotion, counter-act the social determinants of health, and reduce the prevalence of chronic disease. European countries have diverse intersectoral collaboration to encourage health promotion activities. In the Joint Action CHRODIS-PLUS success factors for intersectoral collaboration within and outside healthcare which strengthen health promotion activities were identified with a mixed method design via a survey of 22 project partners in 14 countries and 2 workshops. In six semi-structured interviews, the mechanisms underlying these success factors were examined. These mechanisms can be very context-specific but do give more insight into how they can be replicated. In this paper, 20 health promotion interventions from national programs in CHRODIS PLUS are explored. This includes community interventions, policy actions, integrated approaches, capacity building, and training activities. The interventions involved collaboration across three to more than six sectors. The conclusion is a set of seven recommendations that are considered to be essential for fostering intersectoral collaboration to improve health-promoting activities.

Health promotion and disease prevention often take the form of population- and individual-based interventions that aim to reduce the burden of disease and associated risk factors. There is a wealth of programs, policies, and procedures that have been proven to work in a specific context with potential to improve the lives and quality of life for many people. However, the challenge facing health promotion is how to transfer recognized good practices from one context to another. We present findings from the use of the implementation framework developed in the Joint Action project CHRODIS-PLUS to support the transfer of health promotion interventions for children’s health and older adults identified previously as good practices. We explore the contextual success factors and barriers in the use of an implementation framework in local contexts and the protocol for supporting the implementation. The paper concludes by discussing the key learning points and the development of the next steps for successful transfer of health promotion interventions.

Background: Childhood obesity is a growing public health challenge in Poland and worldwide, associated with serious long-term health consequences. Effective prevention requires family-centered, evidence-based interventions that actively engage both children and their caregivers. This study presents the Finnish Smart Family practice—an evidence-based lifestyle counseling method developed by the Finnish Heart Association—and describes its adaptation and implementation in Poland as part of the EU Health4EUkids project. The study emphasizes the method’s practical utility for professionals working with families of children with obesity. Methods: The Smart Family approach is a structured lifestyle counseling method based on findings from the Special Turku Coronary Risk Factor Intervention Project (STRIP) that is grounded in health psychology and strength-based counseling principles. Unlike traditional counseling, which focuses mainly on information transfer, Smart Family promotes motivation, families’ active participation, and recognition of their strengths in areas such as nutrition, physical activity, sleep, and oral hygiene. The method uses practical tools including the Smart Family card, other supporting materials, and dedicated online platforms for both families and healthcare providers. These tools enable families to self-assess their lifestyle, select discussion topics during visits, and set achievable goals while supporting professionals in initiating non-judgmental, collaborative conversations. In Poland, the program was adapted using culturally appropriate materials and professional training, followed by pilot implementation in primary healthcare and educational settings that included pre-implementation planning, practical training sessions, the application of intervention tools, and outcome evaluation. Results: Pilot implementation demonstrated high usability and effectiveness. The approach enabled non-judgmental, supportive engagement with families, facilitated active participation in setting health goals, and promoted sustainable lifestyle changes in nutrition, physical activity, sleep, and other health behaviors. Evaluation highlighted the importance of supporting program objectives at the national level, standardizing child healthcare practices, and engaging media and local authorities to create a supportive ecosystem. Conclusions: The Polish experience confirms that Smart Family is an evidence-based intervention that strengthens professional competence, provides practical tools for family-centered care, and supports the long-term prevention of child-hood obesity and related non-communicable diseases. Its integration into healthcare and educational settings offers a promising strategy for improving public health outcomes.

Background: Poland is one of six countries implementing the Finnish Smart Family practice under the Joint Action Health4EUKids, aimed at supporting families in adopting lifestyle counseling methods and preventing childhood obesity across the European Union. Material and method: Since March 2024, Poland has implemented Smart Family tools through training sessions for professionals who work or will work with families of children with excess body weight. A total of 295 individuals have been trained, including 52.2% dietitians, 34.9% nurses, and 12.9% school staff such as teachers, school counselors, and psychologists. Before and after the training sessions, participants completed a survey assessing their knowledge of the Smart Family Practice, and familiarity with supportive tools. Results: Among 295 participants, nearly half reported no prior experience with family-based lifestyle change interventions. Post-training, over 70% expressed readiness to implement the SMART FAMILY method, with high interest (80.7%), motivation (76.5%), and satisfaction (83.6%). Most recognized its potential to support healthy lifestyles and parental engagement (>85%). Key barriers included lack of family cooperation (87.8%), staff shortages (81.0%), limited training (78.4%), and insufficient resources (43%). Conclusions: A high level of acceptance and motivation among participants indicates that the SMART FAMILY method has the potential for effective adaptation in Poland. Its implementation requires strengthening specialists’ skills and providing appropriate organizational resources. Overcoming barriers such as lack of experience, limited time, and difficulties in engaging families is crucial to achieving lasting intervention outcomes.
