Background The purpose of this 6-week intervention was to test the feasibility and acceptability of implementing a telehealth-adapted Diabetes Prevention Program (DPP) at a senior center. Methods Older adults (n = 16) attended weekly interactive webinars. At each measurement time point, participants completed questionnaires covering lifestyle, physical activity, quality of life, and food records and wore physical activity trackers. Qualitative data were gathered from 2 focus groups inviting all 16 participants with 13 and 10 participants attending, respectively. Results Over 2000 senior center members were contacted, approximately 2% (n = 39) responded to the recruitment email, and 16 were recruited into the study. Retention was 75%, and attendance rates averaged 80% across the six intervention sessions. The focus group participants provided positive opinions for most program components, especially the webinar group interaction and using physical activity trackers. Suggestions for improvement included a greater focus on specific needs of older adults (i.e., adapting activities) and placing a greater emphasis on dietary strategies to prevent diabetes. Mean weight loss was 2.9% (2.7 kg [95% CI 1.6, 3.7]; p value = 0.001). Conclusion The feasibility of providing DPP via webinar appears to be high based on the retention and attendance rates. Similar to other behavioral interventions engaging older adults, recruitment rates were low. Acceptability was evidenced by high attendance at the intervention sessions and feedback from participants during focus group sessions. The intervention efficacy should be evaluated based on CDC criteria for program recognition in a larger scale randomized trial. Trial registration NCT03524404.

将糖尿病预防计划引入老年人群 (BRIDGE)：一项可行性研究。

背景这项为期 6 周的干预的目的是测试在高级中心实施适用于远程医疗的糖尿病预防计划 (DPP) 的可行性和可接受性。方法 老年人 (n = 16) 参加每周一次的互动网络研讨会。在每个测量时间点，参与者完成了涵盖生活方式、身体活动、生活质量和饮食记录的问卷，并佩戴了身体活动追踪器。定性数据来自 2 个焦点小组，邀请所有 16 名参与者，分别有 13 名和 10 名参与者参加。结果 联系了超过 2000 名高级中心成员，大约 2%（n = 39）回复了招聘电子邮件，并招募了 16 人参与研究。在六次干预会议中，保留率为 75%，出勤率平均为 80%。焦点小组参与者对大多数计划组成部分提供了积极的意见，特别是网络研讨会小组互动和使用身体活动追踪器。改进建议包括更加关注老年人的特定需求（即适应活动）并更加强调预防糖尿病的饮食策略。平均体重减轻为 2.9%（2.7 kg [95% CI 1.6, 3.7]；p 值 = 0.001）。结论 根据保留率和出席率，通过网络研讨会提供 DPP 的可行性似乎很高。与其他涉及老年人的行为干预类似，招募率很低。干预会议的高出席率和焦点小组会议期间参与者的反馈证明了可接受性。在更大规模的随机试验中，干预效果应根据 CDC 项目识别标准进行评估。试用注册NCT03524404。2018 年 5 月 14 日注册 - 追溯注册。试验方案将由通讯作者根据要求提供。
