背景：看电视与死亡风险增加有关，这可能是由久坐不动的生活方式、电视节目内容（例如，香烟广告植入或引起压力的内容）或两者兼而有之造成的。方法：我们使用2008年综合社会调查国家死亡指数数据集，研究了30年来美国成年人的代表性样本中自我报告的电视观看时间与死亡风险之间的关系。我们还探讨了各种情绪状态（如快乐）和信仰（如对政府的信任）对电视观看与死亡率之间关系的干预变量效应。结果：我们发现，每多看一小时电视，死亡风险增加4%。考虑到我们样本中看电视的平均时间，这相当于美国人的预期寿命约为1.2年。这种关联被一些潜在的社会心理中介所缓和，包括自我报告的幸福感、社会资本或对机构的信心。虽然这些因素均无临床意义，但联合中介作用有统计学意义（P < 0.001）。结论：在一项具有全国代表性的美国成年人样本中，健康成年人看电视与过早死亡相关，这种关联可能部分由与信仰或情感状态相关的节目内容介导。然而，这种中介效应是心理社会状态的许多小变化的结果，而不是少数因素的大影响。(C) 2013爱思唯尔公司版权所有。
Background: Television viewing is associated with an increased risk of mortality, which could be caused by a sedentary lifestyle, the content of television programming (e.g., cigarette product placement or stress-inducing content), or both.Methods: We examined the relationship between self-reported hours of television viewing and mortality risk over 30 years in a representative sample of the American adult population using the 2008 General Social Survey National Death Index dataset. We also explored the intervening variable effect of various emotional states (e.g., happiness) and beliefs (e.g., trust in government) of the relationship between television viewing and mortality.Results: We find that, for each additional hour of viewing, mortality risks increased 4%. Given the mean duration of television viewing in our sample, this amounted to about 1.2 years of life expectancy in the United States. This association was tempered by a number of potential psychosocial mediators, including self-reported measures of happiness, social capital, or confidence in institutions. Although none of these were clinically significant, the combined mediation power was statistically significant (P < .001).Conclusions: Television viewing among healthy adults is correlated with premature mortality in a nationally representative sample of U.S. adults, and this association may be partially mediated by programming content related to beliefs or affective states. However, this mediation effect is the result of many small changes in psychosocial states rather than large effects from a few factors. (C) 2013 Elsevier Inc. All rights reserved.
