BACKGROUND
Reducing sedentary behavior and increasing physical activity in people with type 2 diabetes (T2D) are associated with various positive health benefits. Just-in-time adaptive interventions offer the potential to target both of these behaviors through more contextually aware, tailored, and personalized support. We have developed a just-in-time adaptive intervention to promote sitting less and moving more in people with T2D.
OBJECTIVE
This paper presents the study protocol for a microrandomized trial to investigate whether motivational messages are effective in reducing time spent sitting in people with T2D and to determine what behavior change techniques are effective and in which context (eg, location, etc).
METHODS
We will use a 6-week microrandomized trial design. A total of 22 adults with T2D will be recruited. The intervention aims to reduce sitting time and increase time spent standing and walking and comprises a mobile app (iMove), a bespoke activity sensor called Sedentary Behavior Detector (SORD), a messaging system, and a secured database. Depending on the randomization sequence, participants will potentially receive motivational messages 5 times a day.
RESULTS
Recruitment was initiated in October 2022. As of now, 6 participants (2 female and 4 male) have consented and enrolled in the study. Their baseline measurements have been completed, and they have started using iMove. The mean age of 6 participants is 56.8 years, and they were diagnosed with T2D for 9.4 years on average.
CONCLUSIONS
This study will inform the optimization of digital behavior change interventions to support people with T2D Sit Less and Move More to increase daily physical activity. This study will generate new evidence about the immediate effectiveness of sedentary behavior interventions, their active ingredients, and associated factors.

背景
减少2型糖尿病（T2D）患者的久坐行为并增加身体活动与多种积极的健康益处相关。即时自适应干预措施有可能通过更具情境意识、量身定制和个性化的支持来针对这两种行为。我们开发了一种即时自适应干预措施，以促进T2D患者减少久坐并增加活动量。
目的
本文介绍了一项微随机试验的研究方案，以调查动机性信息是否能有效减少T2D患者的久坐时间，并确定哪些行为改变技术是有效的以及在何种情境下（如地点等）有效。
方法
我们将采用为期6周的微随机试验设计。总共将招募22名患有T2D的成年人。该干预旨在减少久坐时间，增加站立和行走时间，包括一个移动应用程序（iMove）、一个名为久坐行为检测器（SORD）的定制活动传感器、一个消息系统和一个安全数据库。根据随机化序列，参与者每天可能会收到5次动机性信息。
结果
招募工作于2022年10月开始。截至目前，已有6名参与者（2名女性和4名男性）同意并参与该研究。他们的基线测量已经完成，并且已经开始使用iMove。6名参与者的平均年龄为56.8岁，他们被诊断出患有T2D的平均时间为9.4年。
结论
本研究将为优化数字行为改变干预措施提供信息，以支持T2D患者减少久坐并增加活动量，从而增加日常身体活动。本研究将产生关于久坐行为干预措施的即时有效性、其有效成分和相关因素的新证据。
