Changing Activity Behavior with Glucose Sensor Feedback

描述（由申请人提供）：本研究将测试使用连续血糖监测系统（CGMS）技术的护士指导咨询干预改变2型糖尿病患者身体活动行为的可行性和实施。在班杜拉自我效能理论框架的指导下，本研究的具体目标是：1)比较接受CGMS咨询干预和接受标准2型糖尿病治疗的参与者在体力活动自我效能感、血压和活动计数方面的变化；2)检验体力活动自我效能感与血压和活动计数结果之间的关系；3)评估最大限度地提高参与者参与体力活动试验的招募、保留和筛选工作。4)评估自我效能感量表的工具可靠性，以及CGMS和活动监测在2型糖尿病人群中的效用。将采用实验设计来评估干预措施的可行性。将从一个地区卫生系统招募50名2型糖尿病患者作为方便样本，随机分为干预组（CGMS咨询，n=25）和对照组（接受2型糖尿病标准教育，n=25）。这些发现将用于设计更大规模的干预研究，以改变2型糖尿病患者的体育活动行为，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.
