Research supports the use of Web-based interventions to promote physical activity in diabetes management. However, previous interventions have found poor levels of engagement or have not included health professionals and people with diabetes in the design of the tool.
To develop and explore the feasibility and indicative effect of a Web-based physical activity promotion intervention in people diagnosed with type 2 diabetes living in remote or rural locations.
A qualitative approach using focus groups that included patients with diabetes and health professionals were run to identify key concepts, ideas, and features, which resulted in the design of a physical activity website. This site was tested using a quantitative approach with a qualitative 6-month pilot study that adopted a three-armed approach. Participants were randomized into three groups: a control group who received written diabetes-specific physical activity advice; an information Web group, a Web-based group who received the information online; and an intervention Web group, an interactive Web-based group who received online information plus interactive features, such as an activity log, personalized advice, and goal setting.
A website was designed based on patient and health professional ideas for effective physical activity promotion. This website was tested with 31 participants, 61% (19/31) male, who were randomized into the groups. Website log-ins decreased over time: 4.5 times in month 1, falling to 3 times in month 6. Both the information Web group-mean 134.6 (SD 123.9) to mean 154.9 (SD 144.2) min-and the control group-mean 118.9 (SD 103.8) to mean 126.1 (SD 93.4) min, d=0.07-increased time spent in moderate-to-vigorous physical activity, but this decreased in the intervention Web group-mean 131.9 (SD 126.2) to mean 116.8 (SD 107.4) min.
Access to online diabetes-specific physical information was effective in promoting physical activity in people with type 2 diabetes; access to interactive features was not associated with increases in activity.

研究支持使用基于网络的干预措施来促进糖尿病管理中的身体活动。然而，先前的干预措施发现参与度较低，或者在工具设计中未纳入健康专业人员和糖尿病患者。
开发并探索一种基于网络的身体活动促进干预措施对居住在偏远或农村地区的2型糖尿病患者的可行性和指示性效果。
采用定性方法，通过焦点小组（包括糖尿病患者和健康专业人员）来确定关键概念、想法和特征，从而设计了一个身体活动网站。该网站通过定量方法进行测试，并进行了为期6个月的定性试点研究，采用三臂试验方法。参与者被随机分为三组：对照组，接受书面的糖尿病特定身体活动建议；信息网络组，通过网络接收信息的一组；干预网络组，接受在线信息以及互动功能（如活动日志、个性化建议和目标设定）的基于网络的互动组。
根据患者和健康专业人员关于有效促进身体活动的想法设计了一个网站。该网站对31名参与者进行了测试，其中61%（19/31）为男性，他们被随机分组。网站登录次数随时间减少：第1个月为4.5次，到第6个月降至3次。信息网络组（从平均134.6（标准差123.9）分钟增加到平均154.9（标准差144.2）分钟）和对照组（从平均118.9（标准差103.8）分钟增加到平均126.1（标准差93.4）分钟，d = 0.07）进行中度至剧烈身体活动的时间均增加，但干预网络组（从平均131.9（标准差126.2）分钟减少到平均116.8（标准差107.4）分钟）的这一活动时间减少。
获取在线糖尿病特定身体信息对促进2型糖尿病患者的身体活动有效；获取互动功能与活动增加无关。
