目的：评估健康行为干预的结果，重点放在小学环境、课堂课程和家庭项目上，用于心血管疾病的初级预防。设计：一项在四个地点进行的随机对照现场试验，包括56个干预和40个对照小学。采用预随机化措施(1991年秋季)和后续措施(1994年春季)对结果进行了评估。参与者-共有5106名来自加利福尼亚州、路易斯安那州、明尼苏达州和德克萨斯州的公立学校的来自不同种族背景的三年级学生。干预。-28所学校参加了三年级到五年级的干预措施，包括修改学校食品服务、加强体育课(PE)和课堂健康课程。另有28所学校接受了这些组成部分和家庭教育。主要结果衡量标准。-在学校层面，两个主要终点是食物服务午餐提供的脂肪含量的变化和体育计划中中等到剧烈的体力活动量的变化。在单个学生的水平上，血清胆固醇的变化是主要的终点，并被用于研究的能量计算。个体水平的次级终点包括心理社会因素，饮食和体力活动模式的回忆测量，以及其他生理测量。结果：干预学校午餐中来自脂肪的能量摄入百分比(从38.7%下降到31.9%)显著高于对照午餐(从38.9%下降到36.2%)(P
Objective.-To assess the outcomes of health behavior interventions, focusing on the elementary school environment, classroom curricula, and home programs, for the primary prevention of cardiovascular disease.Design.-A randomized, controlled field trial at four sites with 56 intervention and 40 control elementary schools. Outcomes were assessed using prerandomization measures (fall 1991) and follow-up measures (spring 1994).Participants.-A total of 5106 initially third-grade students from ethnically diverse backgrounds in public schools located in California, Louisiana, Minnesota, and Texas.Intervention.-Twenty-eight schools participated in a third-grade through fifth-grade intervention including school food service modifications, enhanced physical education (PE), and classroom health curricula. Twenty-eight additional schools received these components plus family education.Main Outcome Measures.-At the school level, the two primary end points were changes in the fat content of food service lunch offerings and the amount of moderate-to-vigorous physical activity in the PE programs. At the level of the individual student, serum cholesterol change was the primary end point and was used for power calculations for the study. individual level secondary end points included psychosocial factors, recall measures of eating and physical activity patterns, and other physiologic measures.Results.-In intervention school lunches, the percentage of energy intake from fat fell significantly more (from 38.7% to 31.9%) than in control lunches (from 38.9% to 36.2%)(P
