每日称重正在成为减肥的推荐自我称重频率。这可能是因为它改善了体重控制行为的采用。目的研究与不经常称重相比，每天称重是否与更大的体重控制行为的采用有关。设计对先前进行的6个月随机对照试验的纵向分析。参与者/设置在北卡罗来纳州查佩尔山的超重男性和女性，参与干预组（N=47）。干预干预的重点是每天使用电子秤称重以减轻体重，电子秤将体重传送到研究网站，沿着每周电子邮件课程以及有关每日称重坚持性和减肥进展的量身定制反馈。主要成果指标我们从电子秤收集了有关自我称重频率的客观数据。在基线和6个月时，在诊所测量体重变化，并通过问卷评估体重控制行为（总项目=37）、饮食策略和体力活动的卡路里消耗。卡路里摄入量通过在线24小时回忆工具进行评估。统计分析我们使用卡方检验来检查离散体重控制行为的变化，并使用线性回归模型来检查体重、饮食策略以及自我称重频率的卡路里摄入和支出的差异。体重低于每日的患者（n=23）的平均自我称重频率为每周5.4 +/- 1.2天。与体重低于每日体重的受试者相比，每日称重的受试者体重减轻显著更多（平均差异=-6.1 kg; 95% CI -10.2至-2.1; P=0.004）。每日称体重者采用的体重控制行为总数更高（17.6 ± 7.6 vs 11.2 ± 6.4; P=0.004）。饮食策略，热量摄入量，或热量expenditure.Conclusions体重的自我称重频率没有差异，每天导致更大的通过体重控制行为，并产生更大的体重减轻相比，称重一周中的大部分日子。这进一步表明每日称重是一种有效的减肥工具。
Background Daily weighing is emerging as the recommended self-weighing frequency for weight loss. This is likely because it improves adoption of weight control behaviors.Objective To examine whether weighing every day is associated with greater adoption of weight control behaviors compared with less frequent weighing.Design Longitudinal analysis of a previously conducted 6-month randomized controlled trial.Participants/setting Overweight men and women in Chapel Hill, NC, participated in the intervention arm (N=47).Intervention The intervention focused on daily weighing for weight loss using an e-scale that transmitted weights to a study website, along with weekly e-mailed lessons and tailored feedback on daily weighing adherence and weight loss progress.Main outcome measures We gathered objective data on self-weighing frequency from the e-scales. At baseline and 6 months, weight change was measured in the clinic and weight control behaviors (total items=37), dietary strategies, and calorie expenditure from physical activity were assessed via questionnaires. Calorie intake was assessed using an online 24-hour recall tool.Statistical analyses We used chi(2) tests to examine variation in discrete weight control behaviors and linear regression models to examine differences in weight, dietary strategies, and calorie intake and expenditure by self-weighing frequency.Results Fifty-one percent of participants weighed every day (n=24) over 6 months. The average self-weighing frequency among those weighing less than daily (n=23) was 5.4 +/- 1.2 days per week. Daily weighers lost significantly more weight compared with those weighing less than daily (mean difference=-6.1 kg; 95% CI -10.2 to -2.1; P=0.004). The total number of weight control behaviors adopted was greater among daily weighers (17.6+7.6 vs 11.2+6.4; P=0.004). There were no differences by self-weighing frequency in dietary strategies, calorie intake, or calorie expenditure.Conclusions Weighing every day led to greater adoption of weight control behaviors and produced greater weight loss compared with weighing most days of the week. This further implicates daily weighing as an effective weight loss tool.
