尽管新的自我监测技术(如活动监测器和智能手机应用程序)激增，但除了结构化的面对面行为干预外，它们对减肥的影响尚不清楚。一项随机、对照的初步研究被用来检验自我监测技术对超重和肥胖成年人6个月体重减轻的效果，包括电话干预和不电话干预。80名参与者被随机分为三组，分别接受标准自我监控工具(ST，n=26)、基于技术的自我监控工具(TECH，n=27)或基于技术的工具结合电话的干预(TECH+Phone，n=27)。所有参与者都参加了一次减肥介绍性会议，并在基线、3个月和6个月完成了评估。从基线到6个月的体重下降在两组之间有显著差异(p=0.042)；Tech+Phone组(−6.4±1.2 kg)的体重下降幅度大于ST组(−1.3±1.2 kg)；Tech组的体重下降(−4.1±1.4 kg)介于ST组和Tech+Phone组之间。与科技和科技+手机(44%)相比，ST(15%)实现的≥减重5%更少，p=.039。Tech+Phone对自我监测卡路里摄入量的坚持程度高于Tech或ST，PS<；0.05。这些结果表明，与传统的自我监测工具相比，使用较新的自我监测技术加上简短的基于电话的干预可以提高依从性和减肥效果。进一步的研究应该确定在提供自我监控技术时增加基于电话的干预的成本效益。
Despite the proliferation of newer self-monitoring technology (e.g., activity monitors and smartphone apps), their impact on weight loss outside of structured in-person behavioral intervention is unknown. A randomized, controlled pilot study was conducted to examine efficacy of self-monitoring technology, with and without phone-based intervention, on 6-month weight loss in adults with overweight and obesity. Eighty participants were randomized to receive standard self-monitoring tools (ST, n=26), technology-based self-monitoring tools (TECH, n=27), or technology-based tools combined with phone-based intervention (TECH+PHONE, n=27). All participants attended one introductory weight loss session and completed assessments at baseline, 3 months, and 6 months. Weight loss from baseline to 6 months differed significantly between groups p=.042; there was a trend for TECH+PHONE (−6.4±1.2kg) to lose more weight than ST (−1.3±1.2kg); weight loss in TECH (−4.1±1.4kg) was between ST and TECH+PHONE. Fewer ST (15%) achieved ≥5% weight losses compared to TECH and TECH+PHONE (44%), p=.039. Adherence to self-monitoring caloric intake was higher in TECH+PHONE than TECH or ST, ps<.05. These results suggest use of newer self-monitoring technology plus brief phone-based intervention improves adherence and weight loss compared to traditional self-monitoring tools. Further research should determine cost-effectiveness of adding phone-based intervention when providing self-monitoring technology.
