電視、不活動、死亡風險
Television Viewing, Inactivity and Dying
去年，西班牙教授馬丁內斯-岡薩雷研究了 13000 相當年輕的大學畢業生，平均年齡只有 37 。在開始時，研究人員記錄了畢業生的電視收看習慣，電腦使用習慣，和每天駕駛汽車時間。然後，平均觀察了 8.3 年的時日；在統計的過程，調整了已知的主要心血管危險因素。
Last year, a Spanish study led by Professor Martinez-Gonzalez studied over 13000 university graduates who are reasonably young, with an average age of 37. They studied this cohort of people over an average of 8.3 years. In the start of the study, their television viewing habits, computer use and total time spent on driving per day were recorded. The major cardiovascular risk factors were adjusted in the statistical modeling.
研究人員發現，這些人若每天看電視多於三小時，比看不到一小時的人，死亡的概率會大兩倍。這跟過去其他研究相似。
The probability of dying from any cause was approximate twice in subjects who watched more than three hours of television compared to those who watched for less than one hour per day.
關鍵不一定是看電視的時間，反而是缺乏體力活動的問題。多花時間看電視，體力活動自然較少。
This finding may be surprising but is in keeping with other studies where the number of television viewing hours are related to unfavorable metabolic profiles. The recurring theme here is physical inactivity. The more hours spent watching television meant less hours spent on physical activities.
身體活動的益處是不可否認的。這項研究令人震驚的地方是在這些畢業生有多年輕。缺乏體力活動的影響是從年輕開始！
The beneficial effect of physical activity is undeniable. The shocking aspect of this study is how young these subjects were. The harmful effect of physical inactivity starts in our prime years!
