Although several previous projects have attempted to address the issue of child obesity through school-based interventions, the overall effectiveness of school-based programs on health-related outcomes in youth has been poor. Thus, it has been suggested that multi-level interventions that aim to influence healthy lifestyle behaviors at the community, school and family levels may prove more successful in the prevention of childhood obesity.
METHODS/DESIGN: This paper describes the rationale, design, and implementation of a community-, school-, and family-based intervention aimed at modifying key behaviors (physical activity, screen time (Internet, television, video games), and nutrition) related to childhood obesity among third through fifth graders in two mid-western cities. The intervention involves a randomized study of 10 schools (5 intervention and 5 control schools). The intervention is being conducted during the duration of the academic year - approximately 9 months - and includes baseline and post-intervention measurements of physical activity, dietary intake, screen time and body composition.
We hope this report will be useful to researchers, public health professionals, and school administrators and health professionals (nurses and physical/health educators) seeking to develop similar prevention programs. It is obvious that more collaborative, inter-disciplinary, multi-level work is needed before a proven, effective intervention package to modify behaviors related to childhood obesity can be generally recommended. It is our hope that SWITCH is a step in that direction.

尽管此前已有多个项目试图通过基于学校的干预措施来解决儿童肥胖问题，但基于学校的项目对青少年健康相关结果的总体效果一直不佳。因此，有人提出，旨在在社区、学校和家庭层面影响健康生活方式行为的多层次干预措施，可能在预防儿童肥胖方面更成功。
方法/设计：本文描述了一项基于社区、学校和家庭的干预措施的基本原理、设计和实施情况，该干预措施旨在改变中西部两个城市三至五年级学生中与儿童肥胖相关的关键行为（体育活动、屏幕时间（上网、看电视、玩电子游戏）和营养）。该干预涉及对10所学校（5所干预学校和5所对照学校）进行随机研究。干预在学年期间进行——约9个月——并包括对体育活动、饮食摄入、屏幕时间和身体成分的基线测量和干预后测量。
我们希望本报告对寻求制定类似预防项目的研究人员、公共卫生专业人员、学校管理人员以及健康专业人员（护士和体育/健康教育工作者）有用。显然，在能够普遍推荐一个经过验证的、有效的干预方案来改变与儿童肥胖相关的行为之前，需要开展更多协作性、跨学科的多层次工作。我们希望“SWITCH”是朝着这个方向迈出的一步。
