And then in the procedure so this is a...you know this is a stress reactivity study and like I mentioned it's about performing a laboratory speech task.

在这个过程中这是一个压力反应能力的研究 正如我前面提到的我们要求试验参与者在实验室发表一个演讲

So individuals underwent a 1-hour resting baseline where they came in and they sat down and kind of relaxed.

每个试验对象休息1小时 并以此作为基线也就是他们进来之后坐下休息一会儿

They did get a catheter in their arm to draw blood but then we left them for an hour period so that their body could reset itself.

然后在他们手臂上缠上导管抽血然后我们离开之后让他们坐在那里休息1小时 让身体恢复

And then individuals did a 20-minute standardized laboratory stress task and this included a speech and a serial subtraction task.

然后每个人开始一个为时20分钟的实验室压力任务这里包括一个演讲和一系列的减法作业

This is kind of the classical speech or stress paradigm And then there was a 70-minute recovery period and blood sampling took place at baseline.

这是一种典型的演讲或压力测试模式然后给他们70分钟的恢复期然后对他们进行采血

30 minutes, 50 and 90 minutes after the beginning of the stressor so that we could kind of look at trajectory of change over time.

采血时间是压力开始后的30分钟50分钟和90分钟这样我们可以看到不同时间的生理变化

Just a brief analytic issue So because of its repeated measures we were able to utilize a multilevel growth curve modeling technique.

这里只简单的讲讲我们的分析过程由于不断的反复检测我们能够使用多层面发展曲线建模技术

Where we can estimate the linear effect It's not particularly important, but... And then we looked at the interactions of time body mass index and sleep.

能够估计出线性效应虽然这不是特别重要然后我们研究了时间身体质量指数和睡眠之间的相互关系

And then when interactions were significant we did simple slope analysis to probe to figure out what it was that was different.

以及这种相互关系什么时候变得显着然后我们做了简单的坡度分析以找出差异在哪里

Again, just descriptive statistics The average age is 60 in the overweight...overweight group in general they had some depressive symptoms.

这只是描述性的统计数据样本的评价年龄为60岁在超重小组中 他们有一些抑郁症状

That all those stuffs were adjusted for in the analysis that I'm gonna show you, and here was their sleep score So the results.

为了便于分析我们对其他所有因素都进行了调整那么我们来看看研究结果

课程简介和演讲视频

课程简介
本套课程讲解了睡眠对健康的多重影响。睡眠不足会改变身体的内分泌系统，打破激素的平衡，扰乱大脑对食物的选择和摄取从而引发肥胖，严重影响胰岛素的平衡进而引发糖尿病。不同年龄段的人群有不同的睡眠需求，一般而言，年轻人的睡眠需求高于老年人，但所有成年人都应保证每天8小时的睡眠时间。

老年人的睡眠时间减少并不是生理变化的自然结果，而是其他疾病造成的影响，衰老本身并不会降低睡眠需求。常见的睡眠障碍包括失眠、睡眠呼吸障碍、四肢不宁综合症、快速眼动期行为失调，患者需要就具体的睡眠障碍咨询专业的睡眠医生，确诊后有针对性的改善睡眠，进而提高整体的健康状况。

不同的睡眠障碍有不同的治疗方式，但认知行为疗法是所有治疗方法的首选，其次是器械治疗、药物治疗以及外科手术治疗。患者应养成良好的睡眠习惯，培养“睡眠卫生习惯”，改善睡眠质量，尽量避免擅自用药和药物滥用。
