Pedometers are an effective self-monitoring tool to increase users' physical activity. However, a range of advanced trackers that measure physical activity 24 hours per day have emerged (eg, Fitbit). The current study aims to determine people's current use, interest and preferences for advanced trackers.
A cross-sectional national telephone survey was conducted in Australia with 1349 respondents.
Regression analyses were used to determine whether tracker interest and use, and use of advanced trackers over pedometers is a function of demographics. Preferences for tracker features and reasons for not wanting to wear a tracker are also presented.
Over one-third of participants (35%) had used a tracker, and 16% are interested in using one. Multinomial regression (n=1257) revealed that the use of trackers was lower in males (OR=0.48, 95% CI 0.36 to 0.65), non-working participants (OR=0.43, 95% CI 0.30 to 0.61), participants with lower education (OR=0.52, 95% CI 0.38 to 0.72) and inactive participants (OR=0.52, 95% CI 0.39 to 0.70). Interest in using a tracker was higher in younger participants (OR=1.73, 95% CI 1.15 to 2.58). The most frequently used tracker was a pedometer (59%). Logistic regression (n=445) revealed that use of advanced trackers compared with pedometers was higher in males (OR=1.67, 95% CI 1.01 to 2.79) and younger participants (OR=2.96, 95% CI 1.71 to 5.13), and lower in inactive participants (OR=0.35, 95% CI 0.19 to 0.63). Over half of current or interested tracker users (53%) prefer to wear it on their wrist, 31% considered counting steps the most important function and 30% regarded accuracy as the most important characteristic. The main reasons for not wanting to use a tracker were, 'I don't think it would help me' (39%), and 'I don't want to increase my activity' (47%).
Activity trackers are a promising tool to engage people in self-monitoring a physical activity. Trackers used in physical activity interventions should align with the preferences of target groups, and should be able to be worn on the wrist, measure steps and be accurate.
计步器是一种有效的自我监测工具，可增加用户的身体活动量。然而，一系列能够全天24小时测量身体活动的先进追踪器已经出现（例如Fitbit）。本研究旨在确定人们目前对先进追踪器的使用情况、兴趣和偏好。
在澳大利亚进行了一项全国性横断面电话调查，共有1349名受访者。
采用回归分析来确定追踪器的兴趣和使用情况，以及与计步器相比先进追踪器的使用情况是否是人口统计学特征的函数。还展示了对追踪器功能的偏好以及不想佩戴追踪器的原因。
超过三分之一的参与者（35%）使用过追踪器，16%的人有兴趣使用追踪器。多项回归分析（n = 1257）显示，男性（OR = 0.48，95% CI 0.36至0.65）、无工作的参与者（OR = 0.43，95% CI 0.从0到0.61）、受教育程度较低的参与者（OR = 0.52，95% CI 0.38至0.72）以及不活跃的参与者（OR = 0.52，95% CI 0.39至0.70）使用追踪器的比例较低。年轻参与者对使用追踪器的兴趣较高（OR = 1.73，95% CI 1.15至2.58）。最常使用的追踪器是计步器（59%）。逻辑回归分析（n = 445）显示，与计步器相比，男性（OR = 1.67，95% CI 1.01至2.从9）和年轻参与者（OR = 2.96，95% CI 1.71至5.13）使用先进追踪器的比例较高，而不活跃的参与者使用比例较低（OR = 0.35，95% CI 0.19至0.63）。超过一半的当前或有兴趣使用追踪器的用户（53%）更喜欢戴在手腕上，31%认为计步是最重要的功能，30%认为准确性是最重要的特征。不想使用追踪器的主要原因是“我认为它对我没有帮助”（39%）和“我不想增加我的活动量”（47%）。
活动追踪器是促使人们自我监测身体活动的一种有前景的工具。用于身体活动干预的追踪器应符合目标群体的偏好，并且应能够戴在手腕上、计步且准确。
