■缺乏身体活动与健康风险有关,导致各种疾病和全因死亡率。尽管建议定期进行体育锻炼(PA),许多成年人仍然不活跃,受社会经济和环境因素的影响。数字干预,特别是基于网络的PA程序,为在人群中推广PA提供了有希望的可能性。这些项目的有效性各不相同,反映了设计上的差异,用户参与度,以及采用的行为改变技术。
■本研究评估了为期12周的基于Web的多模态TKFitnessCoach的有效性。PA在线计划是TK-HealthCoach的一部分。这项研究调查了该计划对自我报告的PA水平的影响,实现目标,健康相关的生活质量,体重,和饮食行为,比较交互式个性化基于网络的干预和非交互式基于网络的健康信息。
■在一项随机对照试验(RCT)中,参与者被分配到干预组(IG),接收对交互式TK-FitnessCoach的访问,或对照组(CG)提供了一个静态网站,其中包含有关PA的循证信息。该研究针对对改善健康行为感兴趣的讲德语的成年人群。在T0(研究开始)评估数据,T1(干预后),T2,6个月,和T3,12个月的随访,关注T3时自我报告的PA和各种次要结局.
■我们在IG和CG中实现了平均分布的社会人口统计学,平均年龄为42.8(IG),resp.43.1年(CG),女性参与者占76.1%(IG),resp.74.7%(CG)。基线时的PA在IG中为277.9分钟/周,在CG中为273.3分钟/周。两者,IG(意向治疗(ITT)数据集n=1153)和CG(ITT数据集n=1177)显示PA随时间显著增加(IG(T3-T0)=72.92min/周;CG(T3-T0)=74.12min/周).然而,在改善PA和相关健康结局方面,本研究未发现交互式TK-FitnessCoach与非交互式对照的有效性存在显著差异.使用TK-FitnessCoach的强度与PA无关。
■这两个项目都有效地在成年人中推广PA,两个RCT组之间没有显着差异。这凸显了数字干预在解决身体活动不足方面的潜力,这表明,这些计划的有效性可能不仅取决于它们的交互性,还取决于所提供信息的质量和相关性。需要进一步的研究来探索此类干预措施的优化策略,特别是对于PA低的人,包括用户参与度,行为改变技术,以及目标PA跟踪方法的集成。

UNASSIGNED: Physical inactivity is associated with health risks, contributing to various diseases and all-cause mortality. Despite recommendations for regular physical activity (PA), many adults remain inactive, influenced by socioeconomic and environmental factors. Digital interventions, particularly web-based PA programs, offer promising possibilities to promote PA across populations. These programs vary in their effectiveness, reflecting differences in design, user engagement, and behavior change techniques employed.
UNASSIGNED: This study evaluates the effectiveness of the 12-week multimodal web-based TKFitnessCoach. The PA online program is part of the TK-HealthCoach. This study investigates the program\'s impact on self-reported PA levels, goal attainment, healthrelated quality of life, body weight, and eating behavior, comparing an interactive personalized web-based intervention and non-interactive web-based health information.
UNASSIGNED: In a randomized controlled trial (RCT), participants were allocated to either the intervention group (IG), receiving access to the interactive TK-FitnessCoach, or the control group (CG) that was provided a static website with evidence-based information on PA. The study targeted a German-speaking adult population interested in improving health behavior. Data was assessed at T0 (beginning of the study), T1 (postintervention), T2, 6 months, and T3, 12 months follow-ups, focusing on self-reported PA at T3 and on various secondary outcomes.
UNASSIGNED: We achieved equally distributed sociodemographics in both the IG and the CG with a mean age of 42.8 (IG), resp. 43.1 years (CG), and female participants of 76.1 % (IG), resp. 74.7 % (CG). PA at baseline was 277.9 min/week in the IG and 273.3 min/week in the CG. Both, the IG (n = 1153 in the Intention-to-treat (ITT) dataset) and CG (n = 1177 in the ITT dataset) exhibited significant increases in PA over time (IG(T3-T0) = 72.92 min/week; CG(T3-T0) = 74.12 min/week).However, the study did not find significant differences in the effectiveness of the interactive TK-FitnessCoach compared to the non-interactive control in terms of improving PA and related health outcomes. The intensity of using the TK-FitnessCoach was not associated with PA.
UNASSIGNED: Both programs were effective in promoting PA among adults, with no significant differences observed between the two RCT groups. This highlights the potential of digital interventions in addressing physical inactivity, suggesting that the effectiveness of such programs may not solely depend on their interactivity but also on the quality and relevance of the information provided. Further research is needed to explore optimization strategies for such interventions, especially for persons with low PA, including user engagement, behavior change techniques, and the integration of objective PA tracking methods.
