BACKGROUND
Interactive web-based physical activity interventions using Web 2.0 features (e.g., social networking) have the potential to improve engagement and effectiveness compared to static Web 1.0 interventions. However, older adults may engage with Web 2.0 interventions differently than younger adults. The aims of this study were to determine whether an interaction between intervention (Web 2.0 and Web 1.0) and age group (<55y and ≥55y) exists for website usage and to determine whether an interaction between intervention (Web 2.0, Web 1.0 and logbook) and age group (<55y and ≥55y) exists for intervention effectiveness (changes in physical activity).
METHODS
As part of the WALK 2.0 trial, 504 Australian adults were randomly assigned to receive either a paper logbook (n = 171), a Web 1.0 (n = 165) or a Web 2.0 (n = 168) physical activity intervention. Moderate to vigorous physical activity was measured using ActiGraph monitors at baseline 3, 12 and 18 months. Website usage statistics including time on site, number of log-ins and number of step entries were also recorded. Generalised linear and intention-to-treat linear mixed models were used to test interactions between intervention and age groups (<55y and ≥55y) for website usage and moderate to vigorous physical activity changes.
RESULTS
Time on site was higher for the Web 2.0 compared to the Web 1.0 intervention from baseline to 3 months, and this difference was significantly greater in the older group (OR = 1.47, 95%CI = 1.01-2.14, p = .047). Participants in the Web 2.0 group increased their activity more than the logbook group at 3 months, and this difference was significantly greater in the older group (moderate to vigorous physical activity adjusted mean difference = 13.74, 95%CI = 1.08-26.40 min per day, p = .03). No intervention by age interactions were observed for Web 1.0 and logbook groups.
CONCLUSIONS
Results partially support the use of Web 2.0 features to improve adults over 55 s' engagement in and behaviour changes from web-based physical activity interventions.

背景
使用 Web 2.0 功能（如社交网络）的交互式网络体育活动干预措施与静态 Web 1.0 干预措施相比，有可能提高参与度和效果。然而，老年人可能与 Web 2.0 干预措施的互动方式与年轻人不同。本研究的目的是确定网站使用是否存在干预（Web 2.0 和 Web 1.0）与年龄组（<55 岁和≥55 岁）之间的相互作用，以及干预（Web 2.0、Web 1.0 和日志）与年龄组（<55 岁和≥55 岁）之间的相互作用是否存在（身体活动的变化）。
方法
作为 WALK 2.0 试验的一部分，504 名澳大利亚成年人被随机分配接受纸质日志（n=171）、Web 1.0（n=165）或 Web 2.0（n=168）体育活动干预。在基线、3、12 和 18 个月时使用 ActiGraph 监测器测量中度到剧烈的身体活动。还记录了网站使用统计数据，包括网站停留时间、登录次数和步骤输入次数。使用广义线性和意向治疗线性混合模型测试干预与年龄组（<55 岁和≥55 岁）之间的网站使用和中度至剧烈身体活动变化的相互作用。
结果
从基线到 3 个月，Web 2.0 的网站停留时间高于 Web 1.0 干预，而在年龄较大的组中，这一差异更为显著（OR=1.47，95%CI=1.01-2.14，p=0.047）。Web 2.0 组在 3 个月时的活动量比日志组增加更多，在年龄较大的组中，这一差异更为显著（中度至剧烈体力活动调整平均差异=13.74，95%CI=1.08-26.40 分钟/天，p=0.03）。在 Web 1.0 和日志组中未观察到干预与年龄的相互作用。
结论
结果部分支持使用 Web 2.0 功能来提高 55 岁以上成年人参与基于网络的体育活动干预措施，并促进他们的行为变化。
