In recent years, school-based interventions have increasingly been used as a strategy to promote good eating habits and physical activity among young people at school. However, little is known about the effect that this kind of public involvement has on the overall behavior of young people. Economists refer to the existence of a crowding-out effect when public sector engagement in influencing behavior is counteracted by behaviors at the individual level. The aim of this study was to investigate the effects of a health promotion intervention program among young people at a vocational school on the overall behavior of the students and consider whether a crowding-out effect existed when it came to health behavior. This study used data from the Gearing up the Body (GUB) intervention that was carried out at the vocational school of Uddannelsescenter Holstebro, Denmark. The study included 130 students from two vocational programs. Answers were collected from survey questions in three waves. Our results showed that intervening in the school setting had the intended impact on physical activity but an unintended impact on eating behavior. In the GUB study, we found signs of countervailing behaviors in and out of school that need to be further explored.
近年来，以学校为基础的干预措施越来越多地被用作一种策略，以促进在校青少年养成良好的饮食习惯和进行体育活动。然而，对于这种公众参与对青少年整体行为的影响，人们知之甚少。当公共部门影响行为的参与被个人层面的行为抵消时，经济学家称存在挤出效应。本研究的目的是调查职业学校青少年健康促进干预项目对学生整体行为的影响，并考虑在健康行为方面是否存在挤出效应。本研究使用了丹麦霍尔斯特布罗教育中心职业学校开展的“增强体质”（GUB）干预项目的数据。该研究包括来自两个职业项目的130名学生。通过三轮调查问题收集答案。我们的结果表明，在学校环境中进行干预对体育活动产生了预期影响，但对饮食行为产生了意外影响。在GUB研究中，我们发现了校内外存在抵消行为的迹象，需要进一步探索。
