This study assessed physical activity patterns in a sample of urban African Americans, whose participation in physical activity has not previously been well-described. From questions administered by interviewers during health fair screenings in 19 churches in East Baltimore, information regarding participation in regular, leisure-time activity (defined as 30 minutes of activity, 5 days per week), time spent walking on the job, and distance walked to and from work was assessed from 365 adults (69% women). Regular, leisure-time activity participation was 18% for men and 16% for women. When the definition of physical activity participation was broadened to include: (1) spending over half the day walking at work; (2) walking at least 10 blocks to and from work; as well as (3) regular, leisure-time activity, 41% of men and 38% of women were active. These data suggest that, while a small percentage of African Americans participate in regular physical activity, a substantial percentage are regularly active when non-leisure-time activity is assessed. To accurately characterize overall participation, physical activity derived from a variety of sources, including transportation and work-related activity, should be assessed.
本研究评估了城市非裔美国人样本中的身体活动模式，此前他们参与身体活动的情况尚未得到充分描述。通过在东巴尔的摩19所教堂健康博览会筛查期间由访谈员提出的问题，从365名成年人（69%为女性）中收集了有关参与定期休闲活动（定义为每周5天、每天30分钟的活动）、工作时步行时间以及上下班步行距离的信息。男性参与定期休闲活动的比例为18%，女性为16%。当身体活动参与的定义扩大到包括：（1）工作时花费半天以上时间步行；（2）上下班至少步行10个街区；以及（3）定期休闲活动时，41%的男性和38%的女性处于活跃状态。这些数据表明，虽然一小部分非裔美国人参与定期体育活动，但在评估非休闲活动时，相当大比例的人经常处于活跃状态。为了准确描述总体参与情况，应评估来自各种来源的身体活动，包括交通和与工作相关的活动。
