在美国，肥胖和2型糖尿病已达到流行比例。据此，增加体育锻炼在降低肥胖和糖尿病的风险中起着重要作用。然而，很少有研究研究了久坐行为，例如长时间的电视（电视）观看和肥胖和糖尿病之间的关联。使用大型前瞻性队列研究中的数据，卫生专业人员的后续研究，我们已经证明，观看电视的增加与肥胖和体重增加密切相关，与饮食和运动无关。同样，长时间的电视观看与2型糖尿病的风险显着增加有关。观看电视超过40小时的男性与每周看电视不到1小时的人相比，2型糖尿病的风险增加了近三倍。与观看电视相关的体育锻炼和不健康的饮食模式的减少并不能完全解释风险。因此，降低肥胖风险和2型糖尿病风险的公共卫生运动不仅应提高运动水平，而且还应降低久坐的行为，尤其是观看延长的电视。
Obesity and type 2 diabetes have reached epidemic proportions in the United States. It is well-established that increasing physical activity plays an important role in reducing risk of obesity and diabetes. Few studies, however, have examined the association between sedentary behaviors such as prolonged television (TV) watching and obesity and diabetes. Using data from a large prospective cohort study, the Health Professionals' Follow-up Study, we have demonstrated that increasing TV watching is strongly associated with obesity and weight gain, independent of diet and exercise. Also, prolonged TV watching is associated with a significantly increased risk of type 2 diabetes. Men who watched TV more than 40 h per week had a nearly threefold increase in the risk of type 2 diabetes compared with those who spent less than 1 h per week watching TV. The increased risk was not entirely explained by the decreased physical activity and unhealthy eating patterns associated with TV watching. Thus, public health campaigns to reduce the risk of obesity and type 2 diabetes should promote not only increasing exercise levels but also decreasing sedentary behaviors, especially prolonged TV watching.
