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 ± 1898 step increase in daily steps compared to an increase of 259 ± 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. Clinicaltrials.Gov Identifier NCT01461707.
引言
孕妇中身体活动不足的情况很普遍，因此迫切需要创新策略来促进身体活动。本研究的目的是测试一项为期12周的移动健康（mHealth）身体活动干预措施的可行性和潜在效果。
方法
2012年12月至2014年2月期间，采用多种招募方法招募参与者。30名妊娠10至20周的孕妇被随机分为干预组（手机应用程序加Fitbit）或对照组（Fitbit）。两种情况都目标是逐步增加身体活动。mHealth干预措施包括每日信息以及带有自动反馈和自我监测系统的手机活动日记。
结果
平均每月通过电话筛选4名女性的初始资格，2.5名被随机分组。在12周时，干预组参与者的每日步数增加了1096±1898步，而对照组参与者增加了259±1604步。在为期12周的研究期间，两组之间每天每周平均步数的变化无统计学意义（p = 0.38）。在12周访视时，干预组报告称，与对照组相比，其在活动、缺乏精力方面的感知障碍较低（p = 0.02）。在为期12周的研究期间，通过移动应用程序回复每日信息和使用每日日记的比例有所下降。
讨论
招募并随机分配孕期想要增加身体活动的不活动女性很困难。有增加身体活动意愿的孕妇可能会发现使用移动技术来评估和促进身体活动是可以接受的。讨论了mHealth干预措施对身体活动无显著治疗效果的可能原因。应提高公众对孕期身体活动安全性和益处的认识。Clinicaltrials.Gov标识符NCT01461707。
