该子项目是利用NIH/NCRR资助的中心赠款提供的资源的许多研究子项目之一。子项目和研究者（PI）可能从另一个NIH来源获得主要资金，因此可以在其他CRISP条目中表示。所列机构为中心，不一定是研究者所在机构。本研究将探讨营养教育对糖尿病结果的影响，理论框架将加强对行为改变过程中潜在介质的评估。该干预措施还将提供有关理想条件的见解，以提供未来有关血糖指数的教育。 翻译后摘要：糖尿病影响~ 6%的美国人口和糖尿病的患病率继续增加。控制血糖是预防糖尿病并发症的关键。糖尿病管理的营养治疗侧重于碳水化合物的数量，而目前的证据也支持碳水化合物质量或血糖指数的潜力。缺乏关于教育客户关于糖尿病管理的碳水化合物（血糖负荷）的数量和质量，从而采用低血糖负荷饮食的有效性的可行性研究。本研究将实施和评估一种基于理论的干预措施，提供有关碳水化合物数量和质量的信息。参与者将参加9个每周一次的教育课程，作为立即或延迟治疗组的一部分。将评价干预对血糖负荷、代谢终点和行为改变的潜在介质的影响。具体而言，结局指标将包括饮食摄入量、知识、自我效能、结局预期、果糖胺、甘油三酯和体重。将在3个时间点采用随机前测-后测设计收集测量值。

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. This study will examine the impact of nutrition education on diabetes outcomes, and the theoretical framework will enhance the assessment of the potential mediators of the behavior change process. The intervention will also offer insights about the ideal conditions for delivering future education about the glycemic index. Abstract: Diabetes affects ~ 6% of the U.S. population and the prevalence of diabetes continues to increase. Controlling blood glucose is critical to prevent diabetes complications. Nutrition therapy for diabetes management focuses on carbohydrate quantity, while current evidence supports a potential for carbohydrate quality, or glycemic index, as well. Feasibility studies regarding the effectiveness of educating clients about the quantity and quality of carbohydrate (glycemic load) for diabetes management and thus adopting a low glycemic load diet are lacking. This study will implement and evaluate a theory-based intervention that presents information about carbohydrate quantity and quality. Participants will attend 9 weekly education sessions as part of an immediate or delayed treatment group. The impact of the intervention on glycemic load, metabolic endpoints and potential mediators of behavior change will be evaluated. Specifically, outcome measures will include dietary intake, knowledge, self-efficacy, outcome expectations, fructosamine, triglycerides, and body weight. The measures will be collected at 3 time points in a randomized pretest-posttest design.
