Pediatrics：低血铅水平也影响儿童的认知能力

　　Pat McLaine博士5月13日在线发布于《儿科》杂志的一项研究成果显示，儿童血铅水平（BLL）低于5微克/分升（µg/dL）与幼儿园入园测试的阅读准备（reading readiness）分数低相关。

　　来自巴尔的摩马里兰大学护理学院的公共卫生学博士和注册护士Pat McLaine和她的同事们，比较了来自美国罗得岛州普罗维登斯公立幼儿园的3406名儿童的幼儿园入园阅读准备测验的分数和美国国务院卫生部记录的儿童血铅检测的水平。

　　研究人员发现，儿童血铅水平的几何平均中位数为4.2µg/dL。五分之一儿童的一个静脉或多个静脉的血铅水平处于10µg/dL或以上。

　　与血铅水平在5～9µg/dL或高于等于10µg/dL的儿童相比，血清水平低于5µg/dL的儿童未达到国家基准的阅读准备分数的儿童更多。两者调整后的流行比为1.21：1.56。平均来说，阅读成绩分别下降4.5和10分。

　　研究结果表明，血清铅水平远低于10µg/dL儿童，幼儿园入园阅读准备分数低。

　　Pat McLaine说：“未来可以通过小学（三年级、四年级）年级期末测验成绩来评价学生的表现。用多元的方式才能，更好的帮助我们了解入园阅读准备分数和铅水平对孩子的长远影响。”

Today, we got a great headlines about Even low red red blood lead levels might stroke children’s cognition. We goal we can suffer it.
Blood lead levels of 5 µg/dL or larger relate with marked down celebration of a mass willingness during entrance to kindergarten, according to a investigate published online May thirteen in Pediatrics.
(HealthDay)—Blood lead levels (BLLs) of 5 µg/dL or larger relate with marked down celebration of a mass willingness during entrance to kindergarten, according to a investigate published online May thirteen in Pediatrics.
Pat McLaine, Dr.P.H., M.P.H., R.N., from a University of Maryland School of Nursing in Baltimore, as good as colleagues related kindergarten celebration of a mass willingness exam scores for 3,406 young kids in attendance open kindergarten in Providence, R.I., with state dialect illness annals of red red blood lead testing.
The researchers found which a median geometric meant BLL was 4.2 µg/dL as good as which one-fifth of young kids had a single or some-more venous BLLs during or upon top of 10 µg/dL. Compared with young kids with BLLs
“These formula indicate which lead bearing during levels good next 10 µg/dL contributes to decreased celebration of a mass willingness during kindergarten entry,” a authors write. “Future analysis of tyro opening upon end-of-grade tests after in facile propagandize (third as good as fourth grades) in this different conspirator could assistance us to improved assimilate a long-term impacts of both kindergarten celebration of a mass willingness as good as childhood lead bearing upon propagandize success.”
