The HEALTHY Study was a 3-year school-based intervention designed to change the behaviors of middle school students to reduce their risk for developing type 2 diabetes mellitus. This report examines the relation between exposure to communications campaign materials and behavior change among students in the HEALTHY intervention schools. Using data from campaign tracking logs and student interviews, the authors examined communications campaign implementation and exposure to the communications campaign as well as health behavior change. Campaign tracking documents revealed variability across schools in the quantity of communications materials disseminated. Student interviews confirmed that there was variability in the proportion of students who reported receiving information from the communication campaign elements. Correlations and regression analysis controlling for semester examined the association between campaign exposure and behavior change across schools. There was a significant association between the proportion of students exposed to the campaign and the proportion of students who made changes in health behavior commensurate with study goals. The results suggest that, in the context of a multifaceted school-based health promotion intervention, schools that achieve a higher rate of exposure to communication campaign materials among the students may stimulate greater health behavior change.
“健康”研究是一项为期 3 年的基于学校的干预措施，旨在改变中学生的行为，降低他们患 2 型糖尿病的风险。本报告探讨了健康干预学校中学生接触传播活动材料与行为改变之间的关系。作者使用来自活动跟踪日志和学生访谈的数据，调查了传播活动的实施情况以及对传播活动的接触情况和健康行为改变情况。活动跟踪文件显示，各所学校传播材料的数量存在差异。学生访谈证实，报告从传播活动要素中获得信息的学生比例存在差异。在控制学期的情况下进行相关性和回归分析，考察了学校之间活动接触与行为改变之间的关联。接触活动的学生比例与与研究目标相符的健康行为改变的学生比例之间存在显著关联。结果表明，在多方面的学校健康促进干预措施的背景下，学生接触传播材料的比例较高的学校可能会激发更大的健康行为改变。
