This study examined the effectiveness of a fully automated web-based programme to increase physical activity in adults with Type 2 diabetes.
Between May and July 2010, participants were randomly allocated into either a 12-week intervention (n=195) or a control (n=202) group. Participants were adults diagnosed with Type 2 diabetes, residing in Australia. Participants were assessed at baseline, 12 and 36weeks. The primary physical activity outcome was self-reported minutes of total physical activity. Secondary physical activity outcomes included minutes spent walking, and engaged in moderate, and vigorous physical activity. Additional measures included website satisfaction and website usage. The intervention consisted of a 12-week web-based physical activity intervention developed based on the Theory of Planned Behavior and self-management framework. Data were analysed from 2011 to 2012.
There was a significant group-by-time interaction (X(2) (df=1)=6.37, p<.05) for total physical activity favouring the intervention group d=0.11, for those who completed the intervention, however this was not significant in the intention-to-treat analysis d=0.01. The intervention yielded high website satisfaction and usage.
In general, there is some evidence for the effectiveness of web-based interventions for improving physical activity levels; however it is clear that maintaining improvements remains an issue.
本研究旨在检验一种完全自动化的网络计划在提高 2 型糖尿病成人身体活动中的有效性。
2010 年 5 月至 7 月，参与者被随机分配到 12 周干预组（n=195）或对照组（n=202）。参与者为被诊断患有 2 型糖尿病且居住在澳大利亚的成年人。参与者在基线、12 周和 36 周进行评估。主要身体活动结果为自我报告的总身体活动分钟数。次要身体活动结果包括步行分钟数以及中等强度和剧烈身体活动分钟数。其他措施包括网站满意度和网站使用情况。干预措施包括基于计划行为理论和自我管理框架开发的 12 周网络身体活动干预。数据于 2011 年至 2012 年进行分析。
总身体活动的组间时间交互作用具有统计学意义（X(2)（df=1）=6.37，p<.05），有利于干预组 d=0.11，但在意向治疗分析中无统计学意义 d=0.01。干预措施产生了较高的网站满意度和使用率。
总的来说，网络干预在提高身体活动水平方面有一定的有效性证据；然而，维持改善仍然是一个问题。
