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 = 0.042; there was a trend for TECH + PHONE (-6.4 ± 1.2 kg) to lose more weight than ST (-1.3 ± 1.2 kg); weight loss in TECH (-4.1 ± 1.4 kg) was between ST and TECH + PHONE. Fewer ST (15%) achieved ≥5% weight losses compared with TECH and TECH + PHONE (44%), P = 0.039. Adherence to self-monitoring caloric intake was higher in TECH + PHONE than TECH or ST, Ps < 0.05.
These results suggest use of newer self-monitoring technology plus brief phone-based intervention improves adherence and weight loss compared with traditional self-monitoring tools. Further research should determine cost-effectiveness of adding phone-based intervention when providing self-monitoring technology.
尽管新型自我监测技术（如活动监测器和智能手机应用程序）不断涌现，但其在结构化面对面行为干预之外对体重减轻的影响尚不清楚。
进行了一项随机对照试验性研究，以检验自我监测技术在有无基于电话的干预情况下，对超重和肥胖成年人6个月体重减轻的效果。80名参与者被随机分为三组，分别接受标准自我监测工具（ST组，n = 26）、基于技术的自我监测工具（TECH组，n = 27）或基于技术的工具结合基于电话的干预（TECH + PHONE组，n = 27）。所有参与者都参加了一次减肥入门课程，并在基线、3个月和6个月时完成评估。
从基线到6个月时，各组间体重减轻差异显著（P = 0.042）；TECH + PHONE组（-6.4 ± 1.2 kg）比ST组（-1.3 ± 1.2 kg）减重更多，存在这种趋势；TECH组（-4.1 ± 1.4 kg）的减重情况介于ST组和TECH + PHONE组之间。与TECH组和TECH + PHONE组（44%）相比，ST组中达到≥5%体重减轻的比例更低（15%），P = 0.039。TECH + PHONE组对自我监测热量摄入的依从性高于TECH组或ST组，P值<0.05。
这些结果表明，与传统自我监测工具相比，使用新型自我监测技术加简短的基于电话的干预可提高依从性并促进体重减轻。进一步的研究应确定在提供自我监测技术时增加基于电话的干预的成本效益。
