So these here are three different exams
所以同一样本群被分为了不同年龄组
at different ages in the same cohort
他们接受了三次不同的测试
And this over the Y axis is the overall effect
Y轴显示的是
relating each unit change in BMI score per hour of sleep
每小时睡眠改变的BMI的总体变化情况
for boys and for girls
有男孩 也有女孩
And what it shows that in boys here at the age 8 to 11
数据显示 对于8到11岁的男孩来说
each 1 hour of decrease in sleep duration
睡眠时间每减少1小时
was associated actually with adjusted 0.31 decrease in BMI z-score
他们的BMI标准分数调整后就会降低0.31
And that actually still was significant
如果我们从横向来看这些数据
when you looked at these relationships cross-sectionally
两者间的联系仍然非常的显着
when the boys were 13 to 16
13到16岁的男孩
although the association was a little bit less
尽管两者的联系稍弱一些
and then it was not significant when they were teens
青少年时期的联系不是很显着
And you see a much much weaker association in girls
大家看到女孩的这种联系相对较弱
However, these were still cross-sectional
然而 这还是横向数据
and then what we did though was ask the question, was:
接下来我们提出了一个问题
did the sleep duration at ages 8 to 11
8到11岁年龄组的睡眠时间
then predicts subsequent BMI first at ages 13 to 16
是否会影响13到16岁年龄组
and then 16 to 19
以及随后16到19岁年龄组的BMI得分?
And this is gonna be a little complicated
这是一个复杂的问题
but let me point this out
但我先把它提出来
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。
