Sedentary work is hazardous. Over 80% of all US jobs are predominantly sedentary, placing full-time office workers at increased risk for cardiovascular and metabolic morbidity and mortality. Thus, there is a critical need for effective workplace physical activity interventions. MapTrek is a mobile health platform that gamifies Fitbit use for the purpose of promoting physical activity. The purpose of this study was to test the efficacy of MapTrek for increasing daily steps and moderate-intensity steps over 10 weeks in a sample of sedentary office workers.
Participants included 146 full-time sedentary office workers aged 21 to 65 who reported sitting at least 75% of their workday. Each participant received a Fitbit Zip to wear daily throughout the intervention. Participants were randomized to either a: (1) Fitbit-only group or 2) Fitbit + MapTrek group. Physical activity outcomes and intervention compliance were measured with the Fitbit activity monitor. The Fitbit + MapTrek group significantly increased daily steps (+2092 steps per day) and active minutes (+11.2 min/day) compared to the Fitbit-only arm, but, on average, participants' steps declined during the study period.
MapTrek is an effective approach for increasing physical activity at a clinically meaningful level in sedentary office workers, but as with accelerometer use alone, the effect decreases over time.

久坐工作有风险。超过 80%的美国工作都是久坐为主，这使得全职办公室工作人员患心血管和代谢疾病的发病率和死亡率上升。因此，非常需要有效的工作场所身体活动干预措施。MapTrek 是一个移动健康平台，它将 Fitbit 的使用游戏化，以促进身体活动。本研究的目的是测试 MapTrek 在增加久坐的办公室工作人员在 10 周内的日常步数和中等强度步数方面的功效。
参与者包括 146 名年龄在 21 至 65 岁之间的全职久坐办公室工作人员，他们报告称每天至少有 75%的工作时间是坐着的。每位参与者都收到了一个 Fitbit Zip，在整个干预期间每天佩戴。参与者被随机分配到以下两组之一：（1）Fitbit 组或（2）Fitbit + MapTrek 组。使用 Fitbit 活动监测器测量身体活动结果和干预依从性。与 Fitbit 组相比，Fitbit + MapTrek 组的日常步数（每天增加 2092 步）和活跃分钟（每天增加 11.2 分钟）显著增加，但参与者的步数在研究期间平均下降。
MapTrek 是一种有效的方法，可以在久坐的办公室工作人员中以临床意义上有意义的水平增加身体活动，但与单独使用加速度计一样，效果会随着时间的推移而降低。
