Abstract

Objective

The SMARTER mobile health (mHealth) weight-loss trial compared adherence to self-monitoring (SM) of diet, physical activity (PA), and weight and adherence to study-prescribed diet and PA goals between SM + feedback (SM + FB) and SM-only arms over 12 months.

Methods

Participants used digital tools to monitor their dietary intake, PA, and weight. We applied generalized linear mixed modeling to compare patterns of monthly adherence to SM and behavioral goals between groups over time and examine the association of adherence to SM and behavioral goals with ≥5% weight loss.

Results

The sample (N = 502) was 80% female and 82% White, with a mean (SD) BMI of 33.7 (4.0) kg/m². Adherence to SM and fat, calorie, and PA goals declined nonlinearly over time, with the SM + FB group displaying less of a decline compared with the SM-only group. Higher adherence to diet, PA, and weight SM and to calorie and PA goals was associated with greater odds of achieving ≥5% weight loss. A higher monthly probability of achieving ≥5% weight loss was associated with greater adherence to diet, PA, and weight SM and to calorie and PA goals.

Conclusions

These results suggest that future research should examine the mechanisms underlying tailored FB to improve the effect of FB intervention strategies that can lead to improved weight loss.

在一项移动健康随机对照试验中，坚持自我监控和行为目标与改善体重减轻有关。

目的：智能移动健康（mHealth）减肥试验比较了SM +反馈（SM + FB）组和仅SM组在12个月内对饮食、身体活动（PA）和体重的自我监测（SM）依从性以及对研究规定饮食和PA目标的依从性。方法：参与者使用数字工具监测他们的饮食摄入量、PA和体重。我们应用广义线性混合模型来比较各组间每月坚持SM和行为目标的模式，并检查坚持SM和行为目标与体重减轻≥5%的关系。结果：样本（N = 502）女性占80%，白人占82%，平均（SD） BMI为33.7 (4.0)kg/m2。坚持SM和脂肪、卡路里和PA目标随时间呈非线性下降，与仅SM组相比，SM + FB组表现出较少的下降。对饮食、PA和体重SM的坚持程度越高，对卡路里和PA目标的坚持程度越高，获得≥5%体重减轻的几率越大。每月体重减轻≥5%的可能性越高，对饮食、PA、体重SM以及卡路里和PA目标的依从性越高。结论：这些结果表明，未来的研究应该研究定制FB的机制，以提高FB干预策略的效果，从而改善体重减轻。
