Sedentary habits in middle-aged individuals are associated with increased risk for cardiovascular disease. Studies examining this association typically have assessed physical activity participation in a narrow window, (for example, 1 week or 1 month) relative to probable disease etiology and progression. The possible relation of long-term physical activity patterns over decades or a lifetime to disease risk is not known because there currently exists no validated method of determining such exposure, but such studies are needed. The goal of this project is to validate self-report methods to assess long-term recall of participation in physical activity. The specific aims of the proposed research are to compare long-term recall of physical activity up to 15 years in the past with physical activity reports and physical fitness levels assessed at the baseline examination. Data to be analyzed for this project are from a cohort that has been under observation in the Aerobics Center Longitudinal Study. Baseline preventive medical examinations were given to 6,902 men and women during the interval from 1971-1982. Current physical activity and physical fitness levels maximal exercise treadmill test) were assessed at baseline. Participants also completed a lifetime physical activity pattern questionnaire as part of a mail survey done in 1986. Self-reported physical activity from the 1986 questionnaire will be used to categorize participants' physical activity levels for the years 1971-1985. These recalled levels of activity will be compared to physical activity and physical fitness levels assessed during those same years at the baseline examinations (measure of truth). For example, participants who reported in the 1986 survey that they engaged in relatively high levels of physical activity in 1976 are expected to have recorded higher levels of physical fitness at the 1976 examination than participants who reported in 1986 that they were relatively sedentary in 1976. The study design will permit evaluation of how accurately participants can recall their physical activity up to 15 years in the past and will allow quantification of the errors investigators might expect from such assessments. Validation of long-term recall of activity can lead to the application of lifetime physical activity patterns questionnaires. Data on lifetime activity patterns will be useful in case-comparison and prospective studies of cardiovascular disease.

中年人久坐不动的习惯与增加 心血管疾病的风险。 研究这种关联 通常在狭窄的窗口内评估身体活动参与， (for例如，1周或1个月）， 进展 长期体力活动模式的可能关系 几十年或一生的疾病风险是未知的，因为有 目前还没有确定这种暴露的有效方法，但这种方法 需要进行研究。 这个项目的目标是验证自我报告 评估参与体力活动的长期回忆的方法。 拟议研究的具体目的是比较长期回忆 在过去15年中， 在基线检查时评估的报告和体能水平。 本项目要分析的数据来自一个队列， 有氧运动中心纵向研究中的观察。 基线预防 在此期间，对6,902名男女进行了体检 从1971年到1982年 目前的身体活动和身体健康水平 最大运动平板试验）在基线时进行评估。 参与者 我还完成了一份终生体育活动模式问卷， 一份1986年的邮件调查 自我报告的身体活动， 1986年的问卷将被用来对参与者的身体状况进行分类。 1971-1985年的活动水平。 这些回忆起的活动水平 将与评估的身体活动和身体健康水平进行比较 在这些年的基线检查（真理的措施）。 例如，在1986年的调查中报告说， 在1976年相对较高的体育活动水平，预计将有 在1976年的考试中， 参与者在1986年报告说，他们相对久坐不动， 1976. 研究设计将允许评估 参与者可以回忆他们过去15年的身体活动 并允许量化调查人员可能期望的错误， 这样的评价。 对活动的长期回忆的验证可能导致 终身体力活动模式问卷的应用。 关于终生活动模式的数据将有助于个案比较， 心血管疾病的前瞻性研究。
