背景路径是第一项以美国-印度学校为基础的多中心研究，旨在测试促进健康饮食和体育活动的肥胖预防计划的有效性。方法SPathways采用嵌套队列设计，将41所学校随机分配到干预或控制条件下，并将这些学校内的学生作为队列进行跟踪(基线为1704名三年级学生)。这项研究的主要终点是体脂百分比。次要终点是学校午餐中的脂肪水平；花在体育活动上的时间；以及关于饮食和锻炼的知识、态度和行为。质量控制(QC)包括设计数据管理系统，为数据收集和处理提供标准化和质量保证。研究中心的数据质量控制程序包括操作手册、培训和认证以及绩效监测。进行了过程评估，以监测干预的剂量和保真度。对学生和学校使用登记和跟踪系统。结果干预学校和对照学校之间没有发现五年级平均体脂百分比的差异。在干预学校，学校午餐中来自脂肪和饱和脂肪的卡路里百分比显着减少，24小时回忆的总能量摄入量也是如此。干预学校学生自我报告的体育活动水平和健康行为知识显著增加。结论路径研究结果为学校在公共卫生促进中的作用提供了证据。它的研究设计和质量控制体系和程序为其他类似的以学校为基础的多点或单点研究提供了有用的模式。
BACKGROUNDPathways was the first multicenter American-Indian school-based study to test the effectiveness of an obesity prevention program promoting healthy eating and physical activity.METHODSPathways employed a nested cohort design in which 41 schools were randomized to intervention or control conditions and students within these schools were followed as a cohort (1,704 third graders at baseline). The study's primary endpoint was percent body fat. Secondary endpoints were levels of fat in school lunches; time spent in physical activity; and knowledge, attitudes, and behaviors regarding diet and exercise. Quality control (QC) included design of data management systems which provided standardization and quality assurance of data collection and processing. Data QC procedures at study centers included manuals of operation, training and certification, and monitoring of performance. Process evaluation was conducted to monitor dose and fidelity of the interventions. Registration and tracking systems were used for students and schools.RESULTSNo difference in mean percent body fat at fifth grade was found between the intervention and control schools. Percent of calories from fat and saturated fat in school lunches was significantly reduced in the intervention schools as was total energy intake from 24-hour recalls. Significant increases in self-reported physical activity levels and knowledge of healthy behaviors were found for the intervention school students.CONCLUSIONSThe Pathways study results provide evidence demonstrating the role schools can play in public health promotion. Its study design and QC systems and procedures provide useful models for other similar school based multi- or single-site studies.
