This study aimed to determine whether weight losses from a primarily smartphone-based behavioral obesity treatment (SMART) differed from those of a more intensive group-based behavioral obesity treatment (GROUP) and a control condition (CONTROL).
A total of 276 adults with overweight/obesity were randomly assigned to 18 months of GROUP-based treatment with meetings weekly for 6 months, meetings biweekly for 6 months, and meetings monthly for 6 months and self-monitoring via paper diaries with written feedback; SMART-based treatment with online lessons, self-monitoring, and feedback plus monthly weigh-ins; or a CONTROL condition with self-monitoring via paper diaries with written feedback and monthly weigh-ins.
Among the 276 participants (17% men; 7.2% minority; mean [SD] age: 55.1 [9.9] years; weight: 95.9 [17.0] kg; BMI: 35.2 [5.0] kg/m ), 18-month retention was significantly higher in both GROUP (83%) and SMART (81%) compared with CONTROL (66%). Estimated mean (95% CI) weight change over 18 months did not differ across the three conditions: 5.9 kg (95% CI: 4.5-7.4) in GROUP, 5.5 kg (95% CI: 3.9-7.1) in SMART, and 6.4 kg (95% CI: 3.7-9.2) in CONTROL.
Mobile online delivery of behavioral obesity treatment can achieve weight loss outcomes that are at least as good as those obtained via the more intensive gold standard group-based approach.
本研究旨在确定主要基于智能手机的行为肥胖治疗（SMART）的体重减轻是否与更强化的基于小组的行为肥胖治疗（GROUP）和对照组（CONTROL）不同。
共有 276 名超重/肥胖成年人被随机分配到 18 个月的 GROUP 治疗中，前 6 个月每周开会一次，之后 6 个月每两周开会一次，最后 6 个月每月开会一次，并通过书面反馈的纸质日记进行自我监测；接受 SMART 治疗，包括在线课程、自我监测和反馈以及每月称重；或接受 CONTROL 治疗，通过书面反馈的纸质日记和每月称重进行自我监测。
在 276 名参与者中（17%为男性；7.2%为少数民族；平均[SD]年龄：55.1[9.9]岁；体重：95.9[17.0]kg；BMI：35.2[5.0]kg/m²），GROUP（83%）和 SMART（81%）的 18 个月保留率明显高于 CONTROL（66%）。18 个月的体重变化估计平均值（95%CI）在三组之间没有差异：GROUP 为 5.9kg（95%CI：4.5-7.4），SMART 为 5.5kg（95%CI：3.9-7.1），CONTROL 为 6.4kg（95%CI：3.7-9.2）。
行为肥胖治疗的移动在线交付可以实现至少与更强化的黄金标准小组方法相当的体重减轻效果。
