To evaluate the use of a wearable activity tracker and brief feedback in the workplace to motivate employees to improve activity.
A total of 135 adult participants were randomized to 1 of 3 groups: control group (blinded to their step activity), intervention group (received counseling based on their step count), or no step-tracking device group. Participants were recruited from June 27, 2016, through February 21, 2018.
Most of the 135 participants were women (84%), with a mean ± SD age of 42.6±10.1 years. Most participants (96%) completed 11 of the 12 weeks of step counts. Comparing treatment groups at week 12 (end of treatment), the intervention group (vs the control group) had significantly more steps (644.8; <.01), had an 11.1% increase in step count from baseline (<.01), was more likely to achieve goal (odds ratio=1.73; =.02), increased distance traveled per week (0.46 miles; <.01) and calories burned (90.6; <.01), and had a decrease in some bioelectrical impedance measurements over time, including a greater loss in body fat mass (-0.90 kg; =.01), percentage fat (-0.96; <.01), and visceral fat level (-0.60; <.01). Finally, the intervention group indicated significantly greater satisfaction with their assigned randomization (89% vs 77%; =.01) and greater confidence in the effectiveness of their activity tracker (<.01).
Brief counseling accompanied by use of a step-counting device can improve workplace activity, which, in turn, can increase steps and decrease body fat, including visceral fat.

评估在工作场所使用可穿戴活动追踪器及简短反馈，以激励员工增加活动量。
共135名成年参与者被随机分为3组中的1组：对照组（对其步数活动不知情）、干预组（根据步数接受咨询）或无步数追踪设备组。参与者于2016年6月27日至2018年2月21日招募。
135名参与者中大多数为女性（84%），平均年龄±标准差为42.6±10.1岁。大多数参与者（96%）完成了12周步数记录中的11周。在第12周（治疗结束时）比较各治疗组，干预组（与对照组相比）步数显著更多（644.8；P<.01），步数较基线增加了11.1%（P<.01），更有可能达到目标（优势比=1.73；P=.02），每周行走距离增加（0.46英里；P<.01），消耗热量增加（90.6；P<.01），并且随着时间推移，一些生物电阻抗测量值有所下降，包括体脂量减少更多（-0.90千克；P=.01）、体脂百分比下降（-0.96；P<.01）和内脏脂肪水平下降（-0.60；P<.01）。最后，干预组对其分配的随机分组表示出显著更高的满意度（89%对77%；P=.01），对其活动追踪器的有效性更有信心（P<.01）。
使用计步设备并辅以简短咨询可改善工作场所的活动，进而增加步数并减少体脂，包括内脏脂肪。
