Despite their utility in accessing ambulatory movement, pedometers have not been used consistently to monitor physical activity in U.S. surveillance systems. This study was designed to determine the feasibility of using pedometers to assess daily steps taken in a sub-sample of adults from Maricopa County who completed the 2014 Arizona Behavioral Risk Factor Surveillance System Survey.
Respondents were sent an Omron HJ324U pedometer, a logbook to record steps taken, and a walking questionnaire. The pedometer was worn for 7 days. Feasibility was assessed for acceptability (interest in study), demand (procedures followed correctly), implementation (time to complete study), and practicality (cost).
Acceptability was modest with 23.9% (830/3476) agreeing to participate. Among those participating (92.9%; 771/830), 50.1% (386/771) returned the logbook. Demand was modest with 39.3% (303/771) of logbooks returned with valid data. Implementation represented 5 months to recruit participants. The cost to obtain valid step-count data was USD61.60 per person. An average of 6363 ± 3049 steps/day were taken with most participants classified as sedentary (36.0%) or low active (35.6%).
The feasibility of using pedometers in a state-based surveillance system is modest at best. Feasibility may potentially be improved with easy-to-use pedometers where data can be electronically downloaded.
尽管计步器在监测日常活动方面具有实用性，但在美国的监测系统中，计步器尚未被持续用于监测身体活动。本研究旨在确定使用计步器评估来自马里科帕县的一部分成年人在2014年亚利桑那行为风险因素监测系统调查中每日步数的可行性。
向受访者发送了一个欧姆龙HJ324U计步器、一本用于记录步数的日志簿以及一份步行调查问卷。计步器需佩戴7天。从可接受性（对研究的兴趣）、需求（正确遵循程序）、实施（完成研究的时间）和实用性（成本）方面评估可行性。
可接受性一般，23.9%（830/3476）的人同意参与。在参与的人中（92.9%；771/830），50.1%（386/771）返还了日志簿。需求一般，39.3%（303/771）返还的日志簿中有有效数据。招募参与者耗时5个月。获取有效步数数据的成本为每人61.60美元。参与者平均每天步行6363±3049步，大多数参与者被归类为久坐不动（36.0%）或活动量低（35.6%）。
在基于州的监测系统中使用计步器的可行性充其量一般。使用易于操作且能电子下载数据的计步器，可行性可能会得到改善。
