目的：我们试图在居住在低收入住房的主要种族和少数民族成年人样本中描述计步器确定的身体活动特征。方法：在低收入住房社区进行的一项随机结肠癌预防干预试验中，收集了433名参与者的基线数据。使用随机效应模型来控制住房站点内的聚类，我们通过几个社会人口特征检查了日常步数的变化。结果：参与者在5天的采样期内平均每天记录5326 （+/- 3871 SD）步数。老年人（P < 0.0001）、女性（P = 0.02）、超重和肥胖（P = 0.03）、每周不锻炼（P = 0.04）以及非工作个体（P < 0.0001）的体力活动水平明显较低。受教育程度和收入没有显著差异。在多变量分析中，年龄、性别、体重指数和就业状况仍与步数显著相关。结论：这些研究结果表明，低收入住房居民缺乏身体活动的患病率很高。这些数据来自一个特征良好的样本，为研究计步器作为低收入、种族和少数民族人口累计体力活动总量的测量方法提供了有用的估计。
Purpose: We sought to characterize pedometer-determined physical activity among a predominantly racial and ethnic minority sample of adults residing in low-income housing. Methods: Data were collected from 433 participants at baseline in a randomized colon cancer prevention intervention trial conducted within low-income housing communities. Using random effects models to control for clustering within housing sites, we examined variation in daily steps by several sociodemographic characteristics. Results: Participants recorded a mean of 5326 (+/- 3871 SD) daily steps over a 5-d sampling period. Significantly lower levels of pedometer-determined physical activity were found among older-aged participants (P < 0.0001), women (P = 0.02), those who were overweight and obese (P = 0.03), those reporting no weekly exercise (P = 0.04), as well as among nonworking individuals (P < 0.0001). No significant differences were found by education or income. In multivariable analyses, age, gender, body mass index, and employment status remained significantly associated with steps. Conclusions: These findings suggest a high prevalence of physical inactivity among low-income housing residents. These data, derived from a well-characterized sample, provide useful estimates for the investigation of pedometers as measures of total accumulated physical activity among lower-income, racial and ethnic minority populations.
