目标.我们评估了2005年波士顿大都市低收入住房的主要种族/少数民族居民中电视观看和计步器确定的身体活动之间的关联。我们使用混合模型分析了486名成年人每天看电视的时间和计步器确定的步数之间的关联。我们还研究了看电视是否与每天10000步的成绩有关。平均每天看电视的时间为3.6小时。在多变量分析中，平均每天每小时看电视与每天少走144步（95%置信区间[CI] =-276，-12）和每天累积10000步的可能性降低相关（比值比[OR] = 0.84; 95% CI = 0.71，0.99）。工作日和周末看电视也与每天较少的步数有关。在这个低收入样本中，平均每天看电视与总计步器确定的身体活动水平（每天约520步）的减少有关。作为全面的身体活动促进计划的一部分，应提出减少看电视的建议。
Objectives. We evaluated the association between television viewing and pedometer-determined physical activity among predominantly racial/ethnic minority residents of low-income housing in metropolitan Boston in 2005.Methods. We used mixed models to analyze the association between reported hours of television viewing and pedometer-determined steps per day among 486 adults. We also examined whether television viewing was associated with the achievement of 10000 steps per day.Results. There was a mean 3.6 hours of average daily television watching. In multivariable analyses, each hour of television viewing on an average day was associated with 144 (95% confidence interval [CI] =-276, -12) fewer steps per day and a decreased likelihood of accumulating 10000 steps per day (odds ratio [OR] = 0.84; 95% Cl = 0.71, 0.99). Weekday and weekend television viewing were each also associated with fewer steps per day.Conclusions. Average daily television viewing was associated with reductions in total pedometer-determined physical activity levels (approximately 520 steps per day) in this lower-income sample. As part of a comprehensive physical activity promotion plan, recommendations to reduce television viewing should be made.
