Physical activity (PA) during pregnancy is associated with a variety of health benefits including a reduced risk of pregnancy related conditions such as pre-eclampsia and pregnancy-induced hypertension and leads to greater control over gestational weight gain. Despite these associated health benefits, very few pregnant women are sufficiently active. In an attempt to increase health outcomes, it is important to explore innovative ways to increase PA among pregnant women. Therefore, the aim of this study was to assess the feasibility, acceptability and efficacy of a four week web-based computer-tailored PA intervention among pregnant women.
Seventy-seven participants were randomised into either: (1) an intervention group that received tailored PA advice and access to a resource library of articles relating to PA during pregnancy; or (2) a standard information group that only received access to the resources library. Objective moderate-to-vigorous physical activity (MVPA) was assessed at baseline and immediately post-intervention. Recruitment, attrition, intervention adherence, and website engagement were assessed. Questions on usability and satisfaction were administered post-intervention.
Feasibility was demonstrated through acceptable recruitment (8.5 participants recruited and randomised/month), and attrition (25%). Acceptability among intervention group participants was positive with high intervention adherence (96% of 4 modules completed). High website engagement (participants logged in 1.6 times/week although only required to log in once per week), usability (75/100), and satisfaction outcomes were reported in both groups. However, participants in the intervention group viewed significantly more pages on the website (p < 0.05), reported that the website felt more personally relevant (p < 0.05), and significantly increased their MVPA from baseline to post-intervention (mean difference = 35.87 min), compared to the control group (mean difference = 9.83 min) (p < 0.05), suggesting efficacy.
The delivery of a computer-tailored web-based intervention designed to increase PA in pregnant women is feasible, well accepted and associated with increases in short-term MVPA. Findings suggest the use of computer-tailored information leads to greater website engagement, satisfaction and greater PA levels among pregnant women compared to a generic information only website.
The trial was 'retrospectively registered' with the Australian New Zealand Clinical Trials Registry ( ACTRN12614001105639 ) on 17 October, 2014.
孕期进行体育活动（PA）与多种健康益处相关，包括降低患先兆子痫和妊娠高血压等妊娠相关疾病的风险，并有助于更好地控制孕期体重增加。尽管有这些相关的健康益处，但很少有孕妇进行足够的体育活动。为了改善健康状况，探索增加孕妇体育活动的创新方法很重要。因此，本研究的目的是评估一项为期四周的基于网络的计算机定制体育活动干预措施对孕妇的可行性、可接受性和有效性。
77名参与者被随机分为两组：（1）干预组，接受量身定制的体育活动建议，并可访问与孕期体育活动相关的文章资源库；（2）标准信息组，仅可访问资源库。在基线和干预结束后立即评估客观的中度至剧烈体育活动（MVPA）。评估招募情况、损耗率、干预依从性和网站参与度。干预结束后进行关于可用性和满意度的问卷调查。
通过可接受的招募率（每月招募并随机分组8.5名参与者）和损耗率（25%）证明了可行性。干预组参与者的接受度良好，干预依从性高（4个模块中有96%完成）。两组均报告了较高的网站参与度（参与者每周登录1.6次，尽管要求每周仅登录一次）、可用性（75/100）和满意度。然而，与对照组相比，干预组参与者在网站上查看的页面明显更多（p < 0.05），报告称该网站感觉更具个人相关性（p < 0.05），并且从基线到干预后其MVPA显著增加（平均差异 = 35.87分钟），而对照组的平均差异为9.83分钟（p < 0.05），表明该干预措施有效。
提供旨在增加孕妇体育活动的计算机定制网络干预措施是可行的，易于接受，并且与短期MVPA的增加相关。研究结果表明，与仅提供一般信息的网站相比，使用计算机定制信息可使孕妇对网站的参与度更高、满意度更高，体育活动水平也更高。
该试验于2014年10月17日在澳大利亚新西兰临床试验注册中心（ACTRN12614001105639）进行了“回顾性注册”。
