Objective研究移动的健康应用程序的自我监测干预是否在短期和长期内减少久坐行为。参与者从医疗机构的工作人员和在线研究公司的注册者中选出。49名参与者被随机分配到对照组（n = 25）或干预组（n = 24）。对照组只获得关于久坐行为的最新信息，干预组在信息之外还提供实时反馈，以进行自我监测。这些干预措施通过智能手机应用程序提供5周（测量短期效果）和13周（测量长期效果）。测量如下：主观总久坐时间（SST），客观总久坐时间（OST），平均久坐持续时间（MSB）和久坐休息次数（SB）。只有SST测量自我报告的基础上，标准化的国际体力活动问卷和其他测量与smartphone.ResultsNo显着的结果，观察在短期内。从长期来看，虽然在客观久坐行为（OST，MSB，SB）方面也没有观察到显着结果，但在主观久坐行为方面观察到显着差异（基线和9/13周之间的SST，βint− β ctrl;分别为1.73和1.50 h/d）。然而，仅向具有智能手机的用户提供关于久坐行为的信息可能会对他们的主观久坐行为的量产生误解。
ObjectiveTo examine whether the self-monitoring interventions of a mobile health app reduce sedentary behavior in the short and long terms.MethodWe designed a double-blind randomized control trial. Participants were selected from among the staff of a medical institution and registrants of an online research firm. Forty-nine participants were randomly assigned to either a control group (n = 25) or an intervention group (n = 24). The control group was given only the latest information about sedentary behavior, and the intervention was provided real-time feedback for self-monitoring in addition to the information. These interventions provided for 5 weeks (to measure the short-term effect) and 13 weeks (to measure the long-term effect) via the smartphone app. Measurements were as follows: subjective total sedentary time (SST), objective total sedentary time (OST), mean sedentary bout duration (MSB), and the number of sedentary breaks (SB). Only SST was measured by self-report based on the standardized International Physical Activity Questionnaire and others were measured with the smartphone.ResultsNo significant results were observed in the short term. In the long term, while no significant results were also observed in objective sedentary behavior (OST, MSB, SB), the significant differences were observed in subjective sedentary behavior (SST, βint− βctrlbetween baseline and 9/13 weeks; 1.73 and 1.50 h/d, respectively).ConclusionsReal-time feedback for self-monitoring with smartphone did not significantly affect objective sedentary behavior. However, providing only information about sedentary behavior to users with smartphones may make misperception on the amount of their subjective sedentary behavior.
