背景:使用习惯发展进行身体活动干预可能会帮助人们增加身体活动,然后随着时间的推移保持身体活动的增加。在一致的环境中制定行为是习惯发展的核心组成部分,然而,其在健康行为习惯发展中的因果作用尚未得到证实。
目的:这项研究测试了在健康行为中习惯发展中一致背景的因果作用,使用计划干预的随机对照试验,在127个活动不足的患者中养成行走习惯,工作,现实生活中的中年成年人。
方法:我们将计划在一致的环境中行走的参与者与计划在不同环境中行走的对照组以及不需要计划平均每日步数变化(使用加速度计测量)和在4周干预期间和4周随访期间自动居住的对照组进行比较。
结果:如预期,一致和多样的环境规划者在干预期间增加了步行,但只有一致的环境规划者发展(并保持)习惯自动化。与预期相反,一致的上下文规划者没有显示步行维护。然而,跨条件,在干预期间养成更多习惯自动化的参与者也保持更多的步行(减少)。有一个常规的每日时间表缓和了一些影响。值得注意的是,无计划控制与更多的常规发展更多的习惯自动化,在更一致的环境中行走。
结论:这项研究证实了一致的环境在养成步行习惯中的因果作用,在现实世界中,与重要但具有挑战性的人群进行身体活动干预,并确定了许多人常见的便利条件:常规时间表。
养成锻炼习惯可以帮助人们增加和保持体力活动。这项研究测试并证实了在一致的环境中锻炼作为形成日常行走习惯的原因的作用。我们使用了一项为期4周的计划干预的随机对照试验,干预后4周随访。127名参与者活动不足,工作,中年成人.我们比较了参与者被要求在每天一致的环境中计划他们的日常散步,参与者被要求在不同的环境中计划他们的散步,参与者不需要计划。不出所料,与不需要计划的参与者相比,在干预期间,一致和多样的情境计划者增加了他们的每日步行步数(使用加速度计测量)。然而,只有一致的环境规划者养成(然后保持)日常行走的习惯,也就是说,每天散步的地方感觉相对自动。出乎意料的是,一致的上下文规划者没有显示步行维护。然而,在所有参与者中,那些在干预期间养成了更强的步行习惯的人在干预结束后保持了更多的步行。最后,有一个现有的日常时间表帮助一些参与者。那些没有被要求计划并且有更常规的日常时间表的人也养成了日常行走的习惯。
BACKGROUND: Physical activity interventions using
habit development may help people increase and then maintain physical activity increases over time. Enacting behavior in consistent contexts is a central component of
habit development, yet its causal role in
habit development in health behaviors has not been confirmed.
OBJECTIVE: This study tests the causal role of consistent context in
habit development in health behavior, using a randomized control trial of a planning intervention to develop a walking habit in 127 insufficiently active, working, midlife adults in a real-world setting.
METHODS: We compare participants who plan walking in consistent contexts with controls who plan walking in varied contexts and with controls not required to plan on a change in average daily steps (measured using an accelerometer) and inhabit automaticity during a 4-week intervention and at a 4-week follow-up.
RESULTS: As expected, consistent and varied context planners increased walking during the intervention, but only consistent context planners developed (and maintained) habit automaticity. Counter to expectations, consistent context planners did not show walking maintenance. However, across conditions, participants who developed more habit automaticity during the intervention also maintained walking more (decreased less). Having a routine daily schedule moderated some effects. Notably, no-plan controls with greater routine developed more habit automaticity, mediated by walking in more consistent contexts.
CONCLUSIONS: This study confirms the causal role of consistent contexts in developing a walking habit, in a real-world setting, with an important but challenging population for physical activity interventions and identifies a facilitating condition common for many: a routine schedule.
Developing an exercise
habit may help people increase and then maintain physical activity. This study tests and confirms the role of exercising in consistent contexts as a cause of forming a daily walking habit. We use a randomized control trial of a 4-week planning intervention, with a follow-up 4 weeks after the intervention. Participants were 127 insufficiently active, working, midlife adults. We compared participants asked to plan their daily walks in consistent contexts from day-to-day, with participants asked to plan their walks in varied contexts and with participants not required to plan. As expected, consistent and varied context planners increased their daily walking steps (measured using an accelerometer) during the intervention compared to participants not required to plan. However, only consistent context planners developed (and then maintained) a daily walking habit, that is, where taking daily walks felt relatively automatic. Unexpectedly, consistent context planners did not show walking maintenance. However, across all participants, those who developed a stronger walking habit during the intervention maintained their walking more after the intervention ended. Lastly, having an existing routine daily schedule helped some participants. Those who were not asked to plan and had a more routine daily schedule also developed a daily walking habit.
