OBJECTIVE: To assess in a randomized controlled trial the effectiveness of dietary education to prevent Type 2 diabetes for a high risk patients of Japanese male workers.RESEARCH DESIGN AND METHODS: This study was a prospective, randomized,controlled clinical trial of two levels of dietary education (DE) in persons with new DE program or conventional DE. The goals of the new DE were to attain and maintain optimal blood glucose levels, to modify nutrient intake and lifestyle as appropriate for prevention, to address individual nutritional needs, taking into consideration personal and cultural preferences as while respecting the individual wishes and willingness to change, and to promote healthy food intake pattern. The study hypothesis was that the new DE might reduce 10% of 2-h fasting plasma glucose (2-h FPG) with a 1 and 6 month DE during 1 year.Data were collected at entry to the study and 1 year after. Subjects were 141 male workers aged over 35 years in a metropolitan area of JAPAN who diagnosed as a high risk group of Type 2diabetes. The sample size was determined based on the information with significant level of 5%, power of 90%, and response rate around 90%. Primary endpoint was 10% reduction of 2-h FPG and improvements of dietary intakes were secondary outcome measures. The data was analyzed using analysis of covariance. Intention to treat was examined using logistic regression analysis.RESULTS: The subjects for the analysis were 170(91.9%) individuals, 88 for new DE, 82 for conventional DE. At 1 year, the new DE resulted in significance improvements in blood glucose control as indicated by 2-h FPG (<0.001) and dietary intakes (<0.001). As for ITT, no evidence was obtained for number of persons with 10% reduction of 2-h FPG.CONCLUSIONS: The new DE provided by dietitians using FFQ resulted in significant improvements and beneficial to high risk persons with Type 2 diabetes.

目的：通过随机对照试验，评价饮食教育对日本男性职工高危人群预防2型糖尿病的有效性。研究设计与方法：本研究是一项前瞻性、随机、对照的两种饮食教育水平的临床试验，适用于新的饮食教育方案和传统的饮食教育方案。新的DE的目标是达到并保持最佳血糖水平，适当调整营养摄入量和生活方式以预防疾病，满足个人的营养需求，同时考虑个人和文化偏好，同时尊重个人的意愿和改变的意愿，并促进健康的食物摄取模式。这项研究的假设是，新的DE可以在1年内用1个月和6个月的DE降低2-h空腹血糖(2-h FPG)的10%。数据收集在研究开始时和1年后。研究对象为日本某大都市141名年龄在35岁以上的男性工作者，他们被诊断为2型糖尿病的高危人群。样本量是根据显著水平为5%、权值为90%、应答率为90%的信息量确定的。主要终点是2小时空腹血糖降低10%，饮食摄入量的改善是次要的结果。数据分析采用协方差分析。结果：170人(91.9%)接受治疗意向分析，88人接受新DE治疗，82人接受传统DE治疗。在一年中，新的DE导致血糖控制显著改善，如2小时空腹血糖(0.001)和饮食摄入量(0.001)所示。至于ITT，没有证据表明2-h空腹血糖减少10%的人数。结论：营养师使用FFQ提供的新DE导致显著改善，对2型糖尿病高危人群有利。
