背景：减肥的自我监测传统上是通过纸质日记进行的。技术进步可以减轻自我监测的负担，并提供反馈以增强依从性。目的：确定只使用PDA进行自我监测饮食还是使用带有每日定制反馈的PDA(PDA+Feedback[FB])进行自我监测饮食优于使用纸质日记进行减肥和维护。设计：使用技术进行自我监测和记录(SMART)试验是一项为期24个月的随机临床试验；参与者被随机分配到三个自我监测组之一。设置/参与者：从2006年到2008年，从社区招募了210名超重/肥胖成年人(84.8%女性，78.1%白人)。2011年对数据进行分析。干预：参与者接受标准的减肥行为治疗，包括饮食和体力活动目标，鼓励使用自我监测，并在小组会议上进行。主要观察指标：24个月时体重变化的百分比，随着时间的推移坚持自我监测。结果：研究保留率为85.6%。两组24个月平均体重下降百分比无差异(纸质日记：-1.94%，95%CI=-3.88，0.01；PDA：-1.38%，95%CI=-3.38，0.62；PDA+FB：-2.32%，95%CI=-4.29，-0.35)；只有PDA+FB组(p=0.02)有显著下降。在坚持自我监控方面，联合PDA组和纸质日记组之间存在逐个治疗组的交互作用(p=0.03)，而PDA组和PDA+FB组之间没有差异(p=0.49)。在所有人群中，坚持60%的人的体重减轻幅度大于
Background: Self-monitoring for weight loss has traditionally been performed with paper diaries. Technologic advances could reduce the burden of self-monitoring and provide feedback to enhance adherence.Purpose: To determine if self-monitoring diet using a PDA only or the PDA with daily tailored feedback ( PDA + feedback [FB]), was superior to using a paper diary on weight loss and maintenance.Design: The Self-Monitoring and Recording Using Technology (SMART) Trial was a 24-month randomized clinical trial; participants were randomly assigned to one of three self-monitoring groups.Setting/participants: From 2006 to 2008, a total of 210 overweight/obese adults (84.8% female, 78.1% white) were recruited from the community. Data were analyzed in 2011.Intervention: Participants received standard behavioral treatment for weight loss that included dietary and physical activity goals, encouraged the use of self-monitoring, and was delivered in group sessions.Main outcome measures: Percentage weight change at 24 months, adherence to self-monitoring over time.Results: Study retention was 85.6%. The mean percentage weight loss at 24 months was not different among groups (paper diary: -1.94%, 95% CI = -3.88, 0.01; PDA: -1.38%, 95% CI = -3.38, 0.62; PDA + FB: -2.32%, 95% CI = -4.29, -0.35); only the PDA + FB group (p = 0.02) demonstrated a significant loss. For adherence to self-monitoring, there was a time-by-treatment group interaction between the combined PDA groups and the paper diary group (p = 0.03) but no difference between PDA and PDA + FB groups (p = 0.49). Across all groups, weight loss was greater for those who were adherent >= 60% versus
