孕妇普遍缺乏身体活动，迫切需要创新的策略来促进身体活动。该研究的目的是测试为期12周的移动的健康（mHealth）身体活动干预的可行性和潜在疗效。方法参与者于2012年12月至2014年2月期间采用多种招募方法招募。30名妊娠10至20周的孕妇被随机分配到干预组（移动的手机应用程序加Fitbit）或对照组（Fitbit）。这两种情况都是针对身体活动的逐渐增加。移动健康干预包括每日信息和带有自动反馈和自我监测系统的移动的电话活动日记。结果每月平均有4名妇女通过电话进行初步资格筛选，2.5名妇女进行随机分组。干预参与者在12周时的每日步数增加了1096 +/-A1898步，而对照参与者增加了259 +/-A1604步。在12周研究期间，两组之间每周平均每天步数的变化无统计学显著性（p = 0.38）。在12周访视时，干预组报告的活动障碍（缺乏能量）低于对照组（p = 0.02）。在12周的研究期间，通过移动的应用程序回复每日消息和使用每日日记的比率下降。讨论很难招募和随机分配不活跃的妇女谁想要增加体力活动在怀孕期间。有动机增加体力活动的孕妇可能会发现使用移动的技术来评估和促进PA是可以接受的。讨论了移动健康干预对身体活动无显著治疗效果的可能原因。应提高公众对怀孕期间体育活动的安全性和益处的认识。
Introduction Physical inactivity is prevalent in pregnant women, and innovative strategies to promote physical activity are strongly needed. The purpose of the study was to test a 12-week mobile health (mHealth) physical activity intervention for feasibility and potential efficacy. Methods Participants were recruited between December 2012 and February 2014 using diverse recruitment methods. Thirty pregnant women between 10 and 20 weeks of gestation were randomized to an intervention (mobile phone app plus Fitbit) or a control (Fitbit) group. Both conditions targeted gradual increases in physical activity. The mHealth intervention included daily messages and a mobile phone activity diary with automated feedback and self-monitoring systems. Results On monthly average, 4 women were screened for initial eligibility by telephone and 2.5 were randomized. Intervention participants had a 1096 +/- A 1898 step increase in daily steps compared to an increase of 259 +/- A 1604 steps in control participants at 12 weeks. The change between groups in weekly mean steps per day during the 12-week study period was not statistically significant (p = 0.38). The intervention group reported lower perceived barrier to being active, lack of energy, than the control group at 12-week visit (p = 0.02). The rates of responding to daily messages and using the daily diary through the mobile app declined during the 12 week study period. Discussion It was difficult to recruit and randomize inactive women who wanted to increase physical activity during pregnancy. Pregnant women who were motivated to increase physical activity might find using mobile technologies in assessing and promoting PA acceptable. Possible reasons for the non-significant treatment effect of the mHealth intervention on physical activity are discussed. Public awareness of safety and benefits of physical activity during pregnancy should be promoted.
