Physical activity is associated with a reduced risk of several chronic diseases. Although there is considerable published research on methods to assess current or recent recreational physical activity, there are few short, self-administered questionnaires designed to assess long-term physical activity.
We developed a one-page questionnaire to capture data on usual recreational physical activity during the preceding 10 years. This questionnaire was used in a cohort study of adults age 50 to 75 years residing in western Washington state. To examine the measurement characteristics of this questionnaire, we compared metabolic equivalent task (MET)-hours derived from this short questionnaire to MET-hours estimated from a detailed comparison interview in a subsample (n = 217) and to current body mass index (BMI; weight in kilograms/height in square meters) in the full sample of 57,811 persons.
The age- and sex-adjusted partial Pearson correlation coefficient for total recreational activity between the 2 instruments was 0.68. In the full cohort, BMI was inversely correlated with physical activity as assessed by the one-page questionnaire (r = -0.22).
This short questionnaire measures long-term physical activity at a level of precision appropriate to the examination of associations in studies of physical activity and disease.
体育活动与多种慢性疾病风险降低相关。尽管已有大量关于评估当前或近期休闲体育活动方法的研究发表，但旨在评估长期体育活动的简短、可自行填写的问卷却很少。
我们设计了一份单页问卷，以收集过去10年中通常的休闲体育活动数据。该问卷用于对居住在华盛顿州西部的50至75岁成年人进行的队列研究。为检验该问卷的测量特征，我们将这份简短问卷得出的代谢当量任务（MET）小时数与在一个子样本（n = 217）中通过详细对比访谈估计的MET小时数以及在57,811人的全样本中的当前体重指数（BMI；千克体重/身高平方米）进行了比较。
两种工具之间总的休闲活动的年龄和性别调整后的偏皮尔逊相关系数为0.68。在整个队列中，BMI与通过单页问卷评估的体育活动呈负相关（r = -0.22）。
这份简短问卷测量长期体育活动的精度水平适用于在体育活动与疾病研究中检验关联。
