As you deviate from 7 hours
當睡眠時間偏離7小時時
mortality rate goes up
死亡率就會上升
and this pattern is generally seen across studies
這一結論得到了很多研究的支持
across continents, across cohorts
不同大洲 不同人群都顯示出這樣的特點
So here is a box
這里有一個方框
A lot of people might put sleep deficiency in the box
很多人會把睡眠不足放入方框中
I'm still not quite so on sleep deficiency
我覺得睡眠不足是不夠的
so I'm a little wordy here
所以我在這里多寫了些內容
So I've got insufficient or excessive sleep duration
我寫的是 睡眠時間不足或過長
and/or inadequate sleep quality
睡眠質量不足
Often they go together
這兩方面通常同時出現
leading to something which leads to mortality
導致死亡率發生變化
So the question is what is that
所以問題在于是什么因素造成了死亡率的變化
So the most obvious answer
最明顯的答案是
is some adverse health outcomes of poor sleep
睡眠質量較差會引發不良健康后果
that is leading to mortality
從而導致死亡率的上升
So what are these adverse health outcomes?
那么不良健康后果是什么呢?
I would purport that here pretty well summaries
我認為這里的信息很好的總結了
what we know about potential adverse outcomes associate with sleep
我們所知的與睡眠相關的不良健康后果
I highlight obesity, waking
我要強調的是肥胖癥 蘇醒
so that's the main reasons here
這些都是主要原因
And also notice that each of these boxes
注意到這里的每個方框
they are not separate boxes with arrows
都不是用箭頭連接的獨立方框
they are all within one big box
它們都屬于一個更大的方框
because if I have to draw all the arrows
因為如果我要用箭頭來表示
in terms of how all these things connected with each other
方框之間的相互關系
we would have arrow salad
那么這里就全是箭頭了
But the point is
關鍵問題在于
that sleep is associated with these outcomes
睡眠會造成一些后果
that are important for cardiometabolic disease
而這些后果對心血管代謝疾病有重大影響
So you have sleep duration and sleep disturbance
有睡眠長短和睡眠的中斷
So here is some data from
這是CDC開展的
the Behavioral Risk Factors Surveillance System conducted by CDC
行為風險因素監控系統得到的數據
They asked questions of very very vague questions
他們向人們提到問題非常的含糊
about sleep disturbance
內容涉及睡眠的中斷情況
where how many nights do you have difficulty falling asleep
有幾個晚上感覺難以入睡
or staying asleep or sleeping too much
或者睡眠時間過長
any kind of sleep problem
內容涉及任何和睡眠障礙相關的問題
