CATCH--A STUDY OF INSTITUTIONALIZATION

描述：两个因素决定了健康促进的最终影响 方案：干预措施影响健康结果的能力， 2000年人口接触和参与方案的程度 风险 到目前为止，对以学校为基础的健康促进计划的研究表明， 以学校为基础的项目可以既有效又有效。 然而，在这方面， 关于如何充分传播现有的有效方案，人们知之甚少 以及如何保持执行水平 在研究阶段就已经证明了。 儿童和青少年审判 心血管健康（CATCH）研究提供了一个独特的机会， 学校健康促进方案的制度化， 自然观察研究。 CATCH是最大的基于学校的健康 美国有史以来资助的促进研究，包括来自 四个地理区域，代表来自不同文化和 种族群体。 本研究的目的是评估 CATCH干预目标（减少脂肪和饱和脂肪， 学校用餐，增加学生花费的时间， 在体育课上进行剧烈的体育活动，90分钟的学校时间用于 体育课、无烟政策与CATCH的实施 课程）被维持或制度化，在原来的56 CATCH干预（最大暴露）学校以及这些学校 同样的CATCH干预结果在20个随机 选定的前CATCH控制（最低暴露）学校。 确定 长期趋势的影响，这些结果的措施也将评估， 12所新招募（未接触）学校。 学校气氛、教师和员工特征、学校 动荡和学校设施和资源将进行评估，以帮助 解释CATCH中制度化程度的变化 干预和控制学校。 结果的重要性， 拟议的研究驻留在他们的未来效用，以计划的扩散， 健康促进计划，包括识别障碍， 促进这些方案制度化的因素。

DESCRIPTION: Two factors determine the ultimate impact of health promotion programs: the ability of interventions to influence health outcomes and the extent of exposure and participation in the program by the population at risk. Research to date on school-based health promotion programs has shown that school- based programs can be both efficacious and effective. However, little is known about how to adequately diffuse effective programs available on a large scale and how to maintain the level of implementation demonstrated during the research phase. The Child and Adolescent Trial for Cardiovascular Health (CATCH) study presents a unique opportunity to study the institutionalization of a school-based health promotion program in a natural observation study. CATCH is the largest school-based health promotion study ever funded in the United States, including schools from four geographical areas and representing students from diverse cultural and ethnic groups. The aims of this study are to assess the degree to which CATCH intervention goals (reduction of the fat and saturated fat offered in school meals, increase in the amount of time students spend in moderate to vigorous physical activity in PE class, 90 minutes of school time devoted to PE class, a policy of no tobacco use and implementation of the CATCH curriculum) are being maintained or institutionalized in the original 56 CATCH intervention (maximally exposed) schools and the degree to which these same CATCH intervention outcomes are being achieved in the 20 randomly selected former CATCH control (minimally exposed) schools. To determine the influence of secular trends, these outcome measures will also be assessed in 12 newly recruited (unexposed) schools. Measures of school climate, teacher and staff characteristics, school turbulence and school facilities and resources will be assessed to help explain the variation in the degree of institutionalization in the CATCH intervention and control schools. The significance of the results from the proposed study reside in their future utility to plan for the diffusion of health promotion programs, including the identification of barriers and facilitating factors involved in the institutionalization of such programs.
