FOOD PURCHASE BEHAVIOR AMONG OLDER ADULTS WITH DIABETES

描述（改编自研究者摘要）：2型糖尿病是 与衰老有关的最常见的慢性疾病之一。营养 治疗可以改善糖尿病患者的血糖控制， 成功管理糖尿病的重要组成部分。营养 食物标签上的资料可指导糖尿病消费者 选择食物产品和膳食份量的决策过程 规划然而，很少有教育计划已经过实证检验， 老年糖尿病患者。此外，很少有研究探讨决策 糖尿病消费者选择食物的过程。因此 本研究的目的是实施和评价营养教育 程序，采用前测后测控制组设计。参与者（n=100） 2型糖尿病患者，至少65岁，将接受随机组 派任实验组的人将参加每周十次的 小组会议。干预措施将整合社会原则， 市场营销、信息处理、学习理论和社会认知 理论干预措施的有效性将根据以下因素进行评估： 使用多项选择测试来衡量知识， 陈述性和程序性知识。参与者对使用的信心 食品标签、食品购买决策策略和食品 也将对采购进行评估。干预对禁食的影响 将测定血浆葡萄糖、糖化血红蛋白和脂质值。的 这项研究有可能改善老年人的生活质量， 糖尿病通过提高他们的信息处理和决策能力， 糖尿病的代谢控制，从而降低并发症的风险 与糖尿病有关。

DESCRIPTION (adapted from investigator's abstract): Type 2 diabetes mellitus is one of the most common chronic diseases associated with aging. Nutrition therapy can improve glycemic control among people with diabetes and is an essential component of successful diabetes management. The nutrition information on food labels can guide consumers with diabetes through the decision-making process of selecting food products and portion sizes for meal planning. However, few educational programs have been empirically tested among older adults with diabetes. Also, few studies have examined the decision-making processes used by consumers with diabetes for food selection. Therefore, the purpose of this study is to implement and evaluate a nutrition education program, using a pretest-posttest control group design. Participants (n=100) with type 2 diabetes, at least 65 years of age, will receive random group assignment. Those in the experimental group will participate in ten weekly group sessions. The intervention will integrate principles from social marketing, information processing, learning theory, and Social Cognitive Theory. The effectiveness of the intervention will be assessed based on measures of knowledge using a multiple-choice test designed to measure declarative and procedural knowledge. Participants' perceived confidence to use the food label, decision-making strategies for food purchases, and food purchases also will be evaluated. The impact of the intervention on fasting plasma glucose, glycated hemoglobin and lipid values will be determined. The study has the potential to improve the quality of life among older adults with diabetes by improving their information processing and decision making skills, metabolic control of diabetes, and thereby reducing the risk of complications associated with diabetes.
