The greatest potential to improve public health lies in the ability of individuals to adopt healthful behaviors. The purpose of this study was to determine whether participation in a facilitator-based video version of the Coronary Health Improvement Project (CHIP) would improve health behaviors and significantly reduce employee health risks. Employees (n = 442) from six worksites in metropolitan Rockford, Illinois, were used in a pretest/posttest design. Employees self-selected to participate in a facilitator-based, CHIP video program. Participants received instruction twice a week, for 8 weeks, via 15 videos shown at each participating worksite. Demographic and biometric data (body weight, body mass index, blood lipids, blood pressure, and fasting blood glucose) were evaluated at baseline and at 8 weeks. All sites individually and collectively demonstrated significant and meaningful reductions in body weight, body mass index, total cholesterol, low-density lipoprotein cholesterol, triglycerides, and fasting blood glucose. Men demonstrated greater improvement than women, and individuals with higher baseline health risks experienced the greatest reductions in risk. The CHIP video program appears to be an effective method of lowering employee health risks. Future research is needed to determine how long these reductions may persist.
改善公众健康的最大潜力在于个人采取健康行为的能力。本研究的目的是确定参与基于辅导员指导的视频版冠状动脉健康改善项目（CHIP）是否会改善健康行为并显著降低员工的健康风险。伊利诺伊州罗克福德市六个工作场所的员工（n = 442）参与了一项前测/后测设计。员工自行选择参与基于辅导员指导的CHIP视频项目。参与者每周接受两次指导，为期8周，通过在每个参与工作场所播放的15个视频进行。在基线和8周时评估人口统计学和生物特征数据（体重、体重指数、血脂、血压和空腹血糖）。所有工作场所个体和总体上在体重、体重指数、总胆固醇、低密度脂蛋白胆固醇、甘油三酯和空腹血糖方面均有显著且有意义的降低。男性的改善程度大于女性，基线健康风险较高的个体风险降低幅度最大。CHIP视频项目似乎是降低员工健康风险的有效方法。需要进一步的研究来确定这些降低效果可能持续的时间。
