Changing Activity Behavior with Glucose Sensor Feedback

描述(由申请人提供)：这项研究将测试护士指导的咨询干预的可行性和实施，使用连续血糖监测系统(CGMS)技术来改变2型糖尿病患者的身体活动行为。在班杜拉自我效能理论框架的指导下，这项研究的具体目标是：1)比较接受CGMS咨询干预的参与者和接受标准2型糖尿病护理的参与者在体力活动自我效能、血压和活动计数方面的变化，2)检查体力活动自我效能与血压和活动计数结果之间的关系，3)评估最大限度地参与体力活动试验的招募、保留和筛选努力，以及4)评估自我效能工具的工具可靠性以及CGMS和活动监测器在2型糖尿病人群中的效用。实验设计将用于评估干预的可行性。将从地区卫生系统招募50名2型糖尿病患者的便利样本，并随机分为干预组(CGMS咨询，n=25)或对照组(接受2型糖尿病标准教育，n=25)。这些发现将被用于设计更大规模的干预研究，以改变2型糖尿病患者的体力活动行为，为自我效能理论做出贡献，并改善行为和健康结果。

DESCRIPTION (provided by applicant): This study will test the feasibility and implementation of a nurse-directed counseling intervention using Continuous Glucose Monitoring System (CGMS) technology to change physical activity behavior in individuals with type 2 diabetes. Guided by a framework derived from Bandura's self-efficacy theory, the study's specific aims are to: 1) compare the change in physical activity self-efficacy, blood pressure and activity counts between participants receiving the CGMS counseling intervention and those receiving standard type 2 diabetes care, 2) examine the relationship between physical activity self-efficacy and outcomes of blood pressure and activity counts, 3) evaluate recruitment, retention, and screening efforts that maximize participant involvement in a physical activity trial, and 4) assess the instrument reliability of self-efficacy instruments and the utility of CGMS and activity monitor utility in the type 2 diabetes population. An experimental design will be used to assess the feasibility of the intervention. A convenience sample of 50 participants with type 2 diabetes will be recruited from a regional health system and randomized to either the intervention (CGMS counseling, n=25) or control group (receiving standard education for type 2 diabetes, n=25). The findings will be used to design larger intervention studies to change physical activity behavior in individuals with type 2 diabetes, to contribute to self-efficacy theory, and improve behavioral and health outcomes.
