We evaluated a pedometer-based community intervention under real-world conditions.
Participants (n=559) provided demographic and health information using surveys and steps/d at baseline and during the last week the participants were in the program. A 1-year follow-up was conducted, but in keeping with real-world conditions, no incentives were offered to participate.
Participants (89% female, age 48.1 [SD=12] years) took 7864 (3114) steps/d at baseline. Postprogram voluntary response rates to mailed surveys were 41.3% at 12 weeks and 22.8% at 1 year. Program completers reported significantly higher steps/d at 12 weeks (approximately 12,000 steps/d) and 1 year (approximately 11,000 steps/d) compared with baseline.
The improvement in steps/d in this real-world implementation was consistent with more controlled studies of pedometer-based interventions. Low response to voluntary follow-up is a study limitation but is expected of real-world evaluations.
我们在实际环境中评估了一项基于计步器的社区干预措施。
参与者（n = 559）在基线时以及参与项目的最后一周通过调查问卷提供人口统计学和健康信息以及每日步数。进行了为期1年的随访，但与实际情况一致，未提供参与激励措施。
参与者（89%为女性，年龄48.1 [标准差 = 12]岁）在基线时每日步数为7864（3114）步。项目结束后，邮寄调查问卷的自愿回复率在12周时为41.3%，在1年时为22.8%。与基线相比，项目完成者在12周时（约每日12,000步）和1年时（约每日11,000步）报告的每日步数显著更高。
在这一实际实施过程中每日步数的增加与基于计步器干预措施的更多对照研究结果一致。自愿随访的低回复率是本研究的一个局限，但在实际评估中是预期的。
