人们对使用信息通信技术治疗肥胖症的兴趣越来越大。智能手机提供的干预可能是一种方便、潜在的成本效益和广泛的体重管理策略。虽然已经有研究将基于短信的干预和智能手机应用程序(APP)用作其他治疗的辅助手段，但目前还没有针对独立的智能手机应用程序进行的随机对照试验(RCT)，这些应用程序主要专注于自我监测饮食和体力活动。这项试点研究的目的是收集智能手机应用程序提供的自我监测体重管理干预的可接受性和可行性结果，并与网站和纸质日记进行比较。128名超重志愿者被随机抽样，接受通过智能手机应用程序、网站或纸质日记进行的体重管理干预。智能手机应用干预，我的用餐伴侣(MMM)，是由研究团队使用循证行为方法开发的。这款应用程序集目标设定、饮食和活动自我监控以及每周短信反馈于一体。该网站小组使用了一家名为减肥资源的公司现有的商业减肥网站，该公司也提供了纸质日记。比较组向该应用程序提供了类似的自我监控干预，但提供方式不同。参与者通过电子邮件、内联网、时事通讯和海报从当地大型雇主那里招募。试验期为6个月。干预组和对照组是自我指导的，没有来自研究团队的持续的人力投入。唯一面对面的部分是在基线登记和6周和6个月的简短跟踪会议上进行人体测量和管理问卷。6个月时，智能手机组尝试保留率为40/43(93%)，网站组为19/42(55%)，日记组为20/43(53%)。智能手机组的饮食记录平均坚持时间为92天(SD 67)，显著高于网站组的35天(SD 44)和日记组的29天(SD 39)(P<；.001)。随着时间的推移，所有组的自我监控能力都有所下降。在对缺失数据进行基线观察的意向治疗分析中，6个月时智能手机应用程序组的平均体重变化为-4.6公斤(95%CI-6.2至-3.0)，日记组为-2.9公斤(95%CI-4.7至-1.1)，网站组为-1.3公斤(95%CI-2.7至0.1)。6个月时BMI变化：智能手机组为-1.6 kg/m2(95%CI-2.2~-1.1)，日记组为-1.0 kg/m2(95%CI-1.6~-0.4)，网站组为-0.5 kg/m2(95%CI-0.9~0.0)。体脂变化：智能手机组为-1.3%(95%CI-1.7~-0.8)，日记组为-0.9%(95%CI-1.5~-0.4)，网站组为-0.5%(95%CI-0.9~0.0)。MMM应用程序是一种可接受和可行的减肥干预措施，这种方法的全面随机对照试验是有保证的。ClinicalTrials.gov NCT01744535；http://clinicaltrials.gov/ct2/show/NCT01744535(由网站http://www.webcitation.org/6FEtc3PVB)存档
There is growing interest in the use of information communication technologies to treat obesity. An intervention delivered by smartphone could be a convenient, potentially cost-effective, and wide-reaching weight management strategy. Although there have been studies of texting-based interventions and smartphone applications (apps) used as adjuncts to other treatments, there are currently no randomized controlled trials (RCT) of a stand-alone smartphone application for weight loss that focuses primarily on self-monitoring of diet and physical activity. The aim of this pilot study was to collect acceptability and feasibility outcomes of a self-monitoring weight management intervention delivered by a smartphone app, compared to a website and paper diary. A sample of 128 overweight volunteers were randomized to receive a weight management intervention delivered by smartphone app, website, or paper diary. The smartphone app intervention, My Meal Mate (MMM), was developed by the research team using an evidence-based behavioral approach. The app incorporates goal setting, self-monitoring of diet and activity, and feedback via weekly text message. The website group used an existing commercially available slimming website from a company called Weight Loss Resources who also provided the paper diaries. The comparator groups delivered a similar self-monitoring intervention to the app, but by different modes of delivery. Participants were recruited by email, intranet, newsletters, and posters from large local employers. Trial duration was 6 months. The intervention and comparator groups were self-directed with no ongoing human input from the research team. The only face-to-face components were at baseline enrollment and brief follow-up sessions at 6 weeks and 6 months to take anthropometric measures and administer questionnaires. Trial retention was 40/43 (93%) in the smartphone group, 19/42 (55%) in the website group, and 20/43 (53%) in the diary group at 6 months. Adherence was statistically significantly higher in the smartphone group with a mean of 92 days (SD 67) of dietary recording compared with 35 days (SD 44) in the website group and 29 days (SD 39) in the diary group (P<.001). Self-monitoring declined over time in all groups. In an intention-to-treat analysis using baseline observation carried forward for missing data, mean weight change at 6 months was -4.6 kg (95% CI –6.2 to –3.0) in the smartphone app group, –2.9 kg (95% CI –4.7 to –1.1) in the diary group, and –1.3 kg (95% CI –2.7 to 0.1) in the website group. BMI change at 6 months was –1.6 kg/m2 (95% CI –2.2 to –1.1) in the smartphone group, –1.0 kg/m2 (95% CI –1.6 to –0.4) in the diary group, and –0.5 kg/m2 (95% CI –0.9 to 0.0) in the website group. Change in body fat was –1.3% (95% CI –1.7 to –0.8) in the smartphone group, –0.9% (95% CI –1.5 to –0.4) in the diary group, and –0.5% (95% CI –0.9 to 0.0) in the website group. The MMM app is an acceptable and feasible weight loss intervention and a full RCT of this approach is warranted.
