We talked about this case of type two but you know in NHANES
这里讲的是2型糖尿病，这是国家健康与营养检测调查
There was a routine assessment of fasting blood glucose and response blood glucose to a standard glucose load
这里日常评估了空腹血糖及标准糖负荷的反应血糖
And whether you look at the fasting or the two-hour post load values
不管是看空腹还是服用后2小时后的值
you see a clear relationship between 25 hydroxy D and the relative risk of having a value that would testifyit was diabetes
25(OH)D能明显减少，测出糖尿病水平值的相对风险
I remind you all these people in which this work was done did not think they had diabetes
要说明的是，所有这些人在研究时都不认为自己患有糖尿病
I mean the answer to the question is no I don't have it
你问他们，他们会说 "我没有"
and so this was the fraction that would or the relative risk of being in fraction that would have a value that would qualify you to be worked up for diabetes
所以，这里说的风险是测量值被认为达到糖尿病水平的相对风险
Now this is true for whites. It was also true for Hispanics
对白人如此，对西班牙裔也是如此
a group that is prone to type two diabetes but in this case it has been already corrected for body mass index
该人群易患2型糖尿病，不过这里根据身体质量指数校正过
which is a key factor difference sometimes between Hispanics and whites in the circumstances
这通常是西班牙裔同白人的关键差异
So you see the same kind of the downward trend
这里有相同的下降趋势
The better your vitamin D status, the less likely you are to have glucose intolerance
维生素D状况越好，葡萄糖耐受性就越好
Reference we made just a few moments ago to the Finnish study. That's a big study
几分钟前我们提到过一个芬兰研究，研究规模很大，
10000 northern Finnish children who were given 2000 IU per day, each day in the first year of life
1万北芬兰孩子让其在一岁前服用2000IU/天，
and the prevalence of type 1 diabetes was assessed 31 years later in
然后在31岁时评估1型糖尿病患病水平
This cohort in a country that keeps good health statistics and therefore it's possible to do this type of work
芬兰的健康统计做得很好，所以这类研究做得下去
