目的自我监测身体活动和饮食是行为减肥计划的关键组成部分。本研究的目的是评估饮食（移动应用程序、网站或纸质期刊）与个人助理（移动应用程序与无移动应用程序）自我监控与饮食和个人助理行为之间的关系。材料与方法本研究是对2010年至2011年进行的96名超重男性和女性（体重指数（BMI） 25-45 kg/m(2)）为期6个月的随机减肥试验的事后分析。两个随机分组的参与者都被崩溃，并根据他们选择的饮食和PA自我监测方法进行分类。所有参与者都接受了通过播客进行的行为减肥干预，并被鼓励自我监测饮食摄入量和PA。结果根据随机分组和人口统计数据进行调整，PA应用程序用户在6个月的研究中更频繁地自我监测锻炼（2.6 +/- 0.5天/周），并且报告的有意PA（196.4 +/- 45.9千卡/天）高于非应用程序用户(1.2 +/- 0.5天/周PA自我监测，p
Objective Self-monitoring of physical activity (PA) and diet are key components of behavioral weight loss programs. The purpose of this study was to assess the relationship between diet (mobile app, website, or paper journal) and PA (mobile app vs no mobile app) self-monitoring and dietary and PA behaviors.Materials and methods This study is a post hoc analysis of a 6-month randomized weight loss trial among 96 overweight men and women (body mass index (BMI) 25-45 kg/m(2)) conducted from 2010 to 2011. Participants in both randomized groups were collapsed and categorized by their chosen self-monitoring method for diet and PA. All participants received a behavioral weight loss intervention delivered via podcast and were encouraged to self-monitor dietary intake and PA.Results Adjusting for randomized group and demographics, PA app users self-monitored exercise more frequently over the 6-month study (2.6 +/- 0.5 days/week) and reported greater intentional PA (196.4 +/- 45.9 kcal/day) than non-app users (1.2 +/- 0.5 days/week PA self-monitoring, p
