The National Diabetes Prevention Program (DPP) promotes lifestyle changes to prevent diabetes. However, only one-third of DPP participants achieve weight loss goals, and changes in diet are limited. Continuous glucose monitoring (CGM) has shown potential to raise awareness about the effects of diet and activity on glucose among people with diabetes, yet the feasibility of including CGM in behavioral interventions for people with prediabetes has not been explored. This study assessed the feasibility of adding a brief CGM intervention to the Arizona Cooperative Extension National DPP. Extension DPP participants were invited to participate in a single CGM-based education session and subsequent 10-day CGM wear period, during which participants reflected on diet and physical activity behaviors occurring prior to and after hyperglycemic events. Following the intervention, participants completed a CGM acceptability survey and participated in a focus group reflecting on facilitators and barriers to CGM use and its utility as a behavior change tool. A priori feasibility benchmarks included opt-in participation rates ≥ 50%, education session attendance ≥ 80%, acceptability scores ≥ 80%, and greater advantages than disadvantages of CGM emerging from focus groups, as analyzed using the Key Point Summary (KPS) method. Thirty-five DPP members were invited to participate; 27 (77%) consented, and 24 of 27 (89%) attended the brief CGM education session. Median survey scores indicated high acceptability of CGM (median = 5, range = 1-5), with nearly all ( = 23/24, 96%) participants believing that CGM should be offered as part of the DPP. In focus groups, participants described how CGM helped them make behavior changes to improve their glucose (e.g., reduced portion sizes, increased activity around eating events, and meditation). In conclusion, adding a single CGM-based education session and 10-day CGM wear to the DPP was feasible and acceptable. Future research will establish the efficacy of adding CGM to the DPP on participant health outcomes and behaviors.
国家糖尿病预防计划（DPP）通过改变生活方式来预防糖尿病。然而，只有三分之一的 DPP 参与者达到了减肥目标，而且饮食的改变也很有限。连续血糖监测（CGM）已经显示出了在糖尿病患者中提高对饮食和活动对血糖影响的认识的潜力，但尚未探索将 CGM 纳入糖尿病前期人群的行为干预措施的可行性。本研究评估了在亚利桑那州合作推广国家 DPP 中增加简短 CGM 干预的可行性。推广 DPP 参与者被邀请参加一次基于 CGM 的教育课程和随后的 10 天 CGM 佩戴期，在此期间，参与者反思了高血糖事件前后的饮食和身体活动行为。干预结束后，参与者完成了 CGM 可接受性调查，并参加了一个焦点小组，讨论 CGM 使用的促进因素和障碍及其作为行为改变工具的效用。预先设定的可行性基准包括选择参与率≥50%、教育课程出席率≥80%、可接受性评分≥80%、以及焦点小组认为 CGM 具有的优势大于劣势，使用 Key Point Summary (KPS) 方法进行分析。邀请了 35 名 DPP 成员参与；27 人（77%）同意，27 人中的 24 人（89%）参加了简短的 CGM 教育课程。中位数调查得分表明 CGM 具有高度可接受性（中位数=5，范围=1-5），几乎所有参与者（=23/24，96%）都认为 CGM 应该作为 DPP 的一部分提供。在焦点小组中，参与者描述了 CGM 如何帮助他们改变行为以改善血糖（例如，减少食物份量、增加进食活动周围的活动量和冥想）。总之，在 DPP 中增加一次基于 CGM 的教育课程和 10 天 CGM 佩戴是可行且可接受的。未来的研究将确定在 DPP 中添加 CGM 对参与者健康结果和行为的效果。
