DESCRIPTION (Principal Investigator's Abstract): During the Phase I project, a computer-assisted instruction (CAI) nutrient analysis methodology was developed so that an individual's own food choices and physical activity could be used as a basis to learn about cardiovascular health and to improve nutrition. The final product was a comprehensive nutrition education package which included a nutrient analysis, diet improvement, software program with a related activity and food record manual, a nutrition workbook, and a statistics/graphics program. The proposed study will demonstrate whether or not an application utilizing this comprehensive package (DINE Weight Management Program) will produce long term weight loss. From a pool of volunteer employees in a worksite setting, eighty employees who are between 20 percent and 35 percent over their ideal body weight, will be randomly assigned to treatment and delayed-treatment groups. The treatment group (n=40) will not receive the program until after the experimental phase of the study. Both groups will be pretested, posttested, and follow-up tested at six months and 12 months. The primary outcome measures will be weight loss and nutrient intake. Weight loss will be determined using a standard protocol and nutrient intake will be determined using three-day food records with food model-assisted interviews (Nutrition Coordinating Center protocol). The research hypothesis is that body weight of employees in the treatment group will decrease from pretest to posttest and will be sustained from posttest to follow-ups, whereas body weight of employees in the control group will remain the same from pre-test to post-test to follow-ups. Scores measuring nutrient intake will improve in the experimental group and will not improve in the control group. Data will be analyzed using two sided t-tests and descriptive data will be presented.

描述（主要研究者摘要）：I期研究期间 项目，一个计算机辅助教学（CAI）营养分析 方法学的发展，使一个人自己的食物选择， 身体活动可以作为基础来了解心血管疾病， 健康和改善营养。 最后的成果是一份全面的 营养教育包，包括营养分析，饮食 改进、具有相关活动和食物记录软件程序 手册，营养工作簿，和统计/图形程序。 的 拟议的研究将证明是否应用 这一全面的一揽子计划（DINE体重管理计划）将产生 长期减肥。 从一群工地的志愿者中 设置，80名员工谁之间的20%和35%以上， 将其理想体重随机分配至治疗组， 延迟治疗组。 治疗组（n=40）将不接受 直到研究的实验阶段结束。 两组将 在6个月和12个月时进行预测试、后测试和随访测试。 主要结果指标将是体重减轻和营养摄入。 将使用标准方案和营养素来确定体重减轻 将使用三天的食物记录确定摄入量， 模型辅助访谈（营养协调中心协议）。 的 研究假设是，治疗组员工的体重 将从测试前到测试后减少，并将从测试后持续 而对照组员工的体重将 从测试前到测试后再到后续测试都是一样的。 分数测量 实验组的营养摄入量会有所改善， 正常对照组 将使用双侧t检验分析数据， 将提供描述性数据。
