giving us an effective size of how strong the relationship

It done by Andrew Steptoe's group

这项工作是由

At the University of College London

And what they did is that they found 32 studies

13 of which had follow-up of over three years

And looked specifically the job stress and the general life stress

主要关注的是工作压力和一般性的生活压力

With the outcomes being kind of the ones you would expect

其测试结果大家都比较熟悉

In epidemiological samples

也就是流行病样本调查

So BMI, waist-to-hip ratio, weight, and waist circumference

I think one important fact about this

我认为有一点非常重要

Was this is these outcomes weren't self-report

所以这些测量数据都比较有效

But the result was somewhat surprising

So there was increasing effects

压力促进肥胖的结果

So meaning that stress predicted

也就是说在8项研究中

An increase in weight in 8 studies

压力导致了体重增加

And null effect in 22 studies

And decreasing effect in 2 of the other studies

而还有2项研究 压力反而导致体重减少

But when taking in total

但总体上来讲

There did seem to be an overall modest relationship

压力和日后的体重之间

Between stress and later weight

确实存在些许关系

With the author saying that

研究者最后这样写道

"psychosocial stress is positively related

在前瞻性研究中

To the development of adiposity in prospective studies

心理压力和肥胖症的发展是存在正向联系的

Although the effects were modest and smaller

尽管和大众常识相比

Than assumed in the lay literature."

两者的联系显得微小而不够显着

So there does seem to be an empirical relationship

所以两者的联系确实得到了实证研究的支持

But it's not an overwhelming one

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。
