概括
两个基于应用程序的干预措施在有高血压妊娠障碍史的妇女中没有增加中度至剧烈的体力活动 (MVPA). 未来的干预措施应考虑自动流程和基线活动水平,以获得更好的结果.
科学领域:
- 行为科学 行为科学
- 心血管疾病研究研究
- 数字健康干预措施 数字健康干预措施
背景情况:
- 不足够的中度至剧烈的体力活动 (MVPA) 是心血管疾病 (CVD) 的重要危险因素.
- 患有高血压妊娠障碍 (HPD) 病史的妇女需要有效的干预措施来增加MVPA并弥合意图-行为差距.
研究的目的:
- 评估两个基于应用程序的8周MVPA干预措施的有效性,基于综合行为变化 (IBC) 模型.
- 通过动机面试和全面的行为改变技术来评估干预措施.
主要方法:
- 一项随机临床试验 (RCT) 涉及619名先前患有HPD的女性.
- 参与者获得了健身追踪器和应用程序,随机分配到控制,动机或行动小组.
- 干预包括8周的信息,动机咨询和行为改变技术,并在9周,3个月和12个月后进行随访.
主要成果:
- 干预组和干预后立即对照组之间没有观察到MVPA的显著差异.
- 行动小组显示对动机和意志过程产生积极影响,但对MVPA没有影响.
- 参与者报告了应用程序和干预组件的积极评价.
结论:
- 基于应用程序的干预措施,即使结合了行为改变技术,也没有显著增加先前患有HPD的女性的MVPA.
- 未来的研究应该探索自动化过程的作用,并考虑干预设计中的高基线活动水平.
- 这些发现为在这个人群中开发未来的MVPA干预和RCT提供了关键的见解.
