Am J Prev Med:长时间看电视可增加多种致死因素的发生风险看电视本身就是一种久坐的行为,与心血管疾病的发生以及癌症发生风险的提高都有关系,但是与其他致死因素发生之间的关系尚未清楚。本研究旨在探究美国电视的收视率与民众主要死因之间的关系。采用前瞻性队列研究分析了221426名年龄在50-71岁的美国民众(57%为男性),基线时期(1995-1996)均未患有慢性疾病,93%的研究对象为白人

看电视本身就是一种久坐的行为,与心血管疾病的发生以及癌症发生风险的提高都有关系,但是与其他致死因素发生之间的关系尚未清楚。本研究旨在探究美国电视的收视率与民众主要死因之间的关系。

采用前瞻性队列研究分析了221426名年龄在50-71岁的美国民众(57%为男性),基线时期(1995-1996)均未患有慢性疾病,93%的研究对象为白人,平均BMI为26.7(SD=4.4)kg/m2。


基线时期记录所有研究对象看电视的情况,并进行随访直至2011年12月31日或研究对象死亡(截止日期之前)。使用Cox比例回归风险模型估计看电视与病因特异性死亡率之间的危险比和95%CIs。

平均随访时间为14.1年,校正混杂因素后发现,每天看电视的时间增加2小时可显著增加以下多种致死因素的死亡率风险:癌症(1.07 [1.03, 1.11]);心脏病(1.23 [1.17, 1.29]);慢性阻塞性肺疾病(1.28 [1.14, 1.43]);糖尿病(1.56 [1.33, 1.83]);流感/肺炎(1.24 [1.02, 1.50]);帕金森病(1.35 [1.11, 1.65]);肝病(1.33 [1.05, 1.67]);自杀(1.43 [1.10, 1.85])。

总而言之,本研究显示,长时间看电视与多种致死因素有关,新确定了几种主要的致死原因与看电视之间存在关联。看电视是机体的一种可自行控制的行为,因此,它或可成为公共卫生干预的一个重要靶点。
