这项研究的目的是在8885名成年人中确定看电视时间与心血管健康之间的关系。还检查了年龄、性别、吸烟、每周工作时间、每周锻炼时间和肥胖等潜在的混杂影响。在控制了年龄和性别的情况下，每天看电视超过4小时的受试者(经常看电视的人)身体健康的可能性是每天看电视不到1小时的受试者(不经常看电视的人)的0.37倍。同样，每天看电视3-4个小时的成年人(中等频率的观众)健康的可能性是不经常看电视的人的0.45倍。对潜在的混杂因素进行调整，特别是测量的身体脂肪和报告的运动持续时间相结合，适度削弱了看电视/健身的关系。鉴于这项研究的结果和之前的研究结果，应该谨慎对待过度观看电视。
The purpose of this study was to determine the extent to which time spent watching television is associated with cardiovascular fitness among 8,885 adults. Potential confounding effects of age, gender, smoking, length of work week, time reported exercising each week, and obesity were also examined. Subjects who watched TV more than 4 hours per day (frequent viewers) were 0.37 times as likely to be physically fit as those who watched TV less than 1 hour per day (infrequent viewers) with age and gender controlled. Similarly, adults who watched TV 3-4 hours per day (moderately frequent viewers) were 0.45 times as likely to be fit as infrequent watchers. Adjustment for potential confounders, particularly measured body fat and reported exercise duration in combination, weakened the TV viewing/fitness relation moderately. Given the findings of this study and the results of previous research, caution should be exercised regarding excessive television viewing.
