背景-看电视时间是主要的休闲时间久坐行为，与心脏代谢风险的生物标志物相关，但其与死亡率的关系尚未研究。我们研究了澳大利亚成年人延长看电视时间与全因、心血管疾病 (CVD)、癌症和非 CVD/非癌症死亡率之间的关系。方法和结果 - 在澳大利亚糖尿病、肥胖和生活方式研究 (AusDiab) 中，对 8800 名 25 岁以上成年人中看电视时间与随后的全因、CVD 和癌症死亡率（中位随访时间为 6.6 年）的关系进行了研究。在 58 087 人年的随访中，有 284 人死亡（87 人死于 CVD，125 人死于癌症）。调整年龄、性别、腰围和运动量后，每天看电视时间每增加 1 小时，全因死亡率的风险比为 1.11（95% 置信区间 [CI]，1.03 至 1.20），CVD 死亡率为 1.18（95% CI，1.03 至 1.35），1.09（95% CI，0.96 至 1.23）对于癌症死亡率。与观看电视时间<2小时/天相比，>=2至<4小时/天的全因死亡率的完全调整风险比为1.13（95%CI，0.87至1.36），>=4小时/天的全因死亡率为1.46（95%CI，1.04至2.05）。对于CVD死亡率，相应的风险比为1.19（95% CI，0.72至1.99）和1.80（95% CI，1.00至3.25）。与癌症死亡率和非 CVD/非癌症死亡率的相关性并不显着。结论：看电视时间与全因死亡率和 CVD 死亡率的风险增加相关。除了促进锻炼之外，慢性病预防策略还可以集中于减少久坐时间，尤其是长时间看电视。 （流通。2010 年；121：384-391。）
Background-Television viewing time, the predominant leisure-time sedentary behavior, is associated with biomarkers of cardiometabolic risk, but its relationship with mortality has not been studied. We examined the associations of prolonged television viewing time with all-cause, cardiovascular disease (CVD), cancer, and non-CVD/noncancer mortality in Australian adults.Methods and Results-Television viewing time in relation to subsequent all-cause, CVD, and cancer mortality (median follow-up, 6.6 years) was examined among 8800 adults > 25 years of age in the Australian Diabetes, Obesity and Lifestyle Study (AusDiab). During 58 087 person-years of follow-up, there were 284 deaths (87 CVD deaths, 125 cancer deaths). After adjustment for age, sex, waist circumference, and exercise, the hazard ratios for each 1-hour increment in television viewing time per day were 1.11 (95% confidence interval [CI], 1.03 to 1.20) for all-cause mortality, 1.18 (95% CI, 1.03 to 1.35) for CVD mortality, and 1.09 (95% CI, 0.96 to 1.23) for cancer mortality. Compared with a television viewing time of < 2 h/d, the fully adjusted hazard ratios for all-cause mortality were 1.13 (95% CI, 0.87 to 1.36) for >= 2 to < 4 h/d and 1.46 (95% CI, 1.04 to 2.05) for >= 4 h/d. For CVD mortality, corresponding hazard ratios were 1.19 (95% CI, 0.72 to 1.99) and 1.80 (95% CI, 1.00 to 3.25). The associations with both cancer mortality and non-CVD/noncancer mortality were not significant.Conclusions-Television viewing time was associated with increased risk of all-cause and CVD mortality. In addition to the promotion of exercise, chronic disease prevention strategies could focus on reducing sitting time, particularly prolonged television viewing. (Circulation. 2010;121:384-391.)
