A new study found that women who took folic acid supplements in early pregnancy were less likely to have a child with autism. Folic acid is a B vitamin that helps the body build and repair cells. The study did not prove that folic acid can prevent childhood autism, but the findings suggest a connection. The researchers called for examining whether folic acid is associated with a reduced risk of other brain disorders in children. 一項最新研究發(fā)現(xiàn)，在懷孕早期服用葉酸的孕婦生下的孩子患有孤獨(dú)癥的幾率更小。葉酸是一種維生素B，能幫助身體發(fā)育和修復(fù)細(xì)胞。這項研究未能證明葉酸可以預(yù)防兒童孤獨(dú)癥，但發(fā)現(xiàn)結(jié)果表明兩者存在關(guān)聯(lián)。研究者呼吁進(jìn)行調(diào)查，看葉酸是否能減少兒童患上其他大腦疾病的風(fēng)險。
Children with autism have problems communicating and socializing with other people. 患有孤獨(dú)癥的兒童存在溝通與社交障礙。
Researchers at the Norwegian Institute of Public Health looked at records of more 85,000 children born between 2002 and 2008. 挪威國家公共衛(wèi)生研究院的研究者查看了8.5萬名生于2002到2008年的兒童。
The study asked mothers to describe their diets, including vitamins and other nutritional treatments, before and during their pregnancies. 他們向母親們調(diào)查懷孕前后的飲食、維生素和其他營養(yǎng)療法。
Research leader Pal Suren and his colleagues compared the women who took folic acid supplements to those who did not. 研究負(fù)責(zé)人Pal Suren和同事對比了服用葉酸補(bǔ)充劑和沒有服用的婦女。
"The women who took folic acid supplements in early pregnancy had a substantial reduction in risk of having a child with autism. The reduction was 40 percent." “在懷孕早期服用葉酸的孕婦生下的孩子患有孤獨(dú)癥的幾率更小，能降低40%的發(fā)病率?！?BR> He says the best time to take folic acid to reduce the risk of autism seems to be from four weeks before to eight weeks after the start of pregnancy. The researchers found that taking folic acid halfway through pregnancy had no effect. 他說，為降低孤獨(dú)癥的幾率，服用葉酸的時間是懷孕后第四周到第八周之間。研究者發(fā)現(xiàn)在孕期中間服用葉酸沒有效果。
After the babies were born, investigators followed up with the children through the end of March 2012. They wanted to find out how many developed any form of autism. Two hundred seventy of the children had some form of autism. The study found no reduction in the risk of some forms of autism. But it did find a lower risk for the most severe form. There were not enough children with a milder form known as Asperger's syndrome to make any findings. 嬰兒出生后，調(diào)查者一直跟進(jìn)研究到2012年3月，他們想了解到底多少孩子患上孤獨(dú)癥。有270名兒童患上某種形式的孤獨(dú)癥，研究發(fā)現(xiàn)某些孤獨(dú)癥的發(fā)病風(fēng)險沒有降低。但最嚴(yán)重的那些類型確實降低了，同時，也沒有足夠數(shù)量的兒童患上中度艾斯伯格綜合癥來進(jìn)行研究。
The cause of autism is not known, but several genes may play a part. 孤獨(dú)癥的發(fā)病原因尚未知，但幾種基因會起到作用。
Folic acid has been linked to the development of a protective covering called the neural tube in a fetus. Women who do not get enough folic acid are at risk of giving birth to infants with part of their spinal cord or brain exposed. This disabling condition is called spina bifida. 葉酸與胎兒體內(nèi)名為神經(jīng)管的保護(hù)層的形成有關(guān)，那些服用葉酸不充足的孕婦，其產(chǎn)下的嬰兒可能有部分脊柱外露，這種疾病叫脊柱裂。
Ezra Susser of Columbia University in New York City was a co-author of the new study of folic acid. 紐約哥倫比亞大學(xué)的Ezra Susser是這份有關(guān)葉酸研究的合作者。
"These supplements are already recommended for other reasons. So this increases the reasons why we should recommend them." “我們推薦服用葉酸還有其他原因，因此更應(yīng)該推薦使用?！?BR> Dark leafy vegetables, asparagus, broccoli and citrus fruit are rich sources of folate. Folate is the naturally occurring form of folic acid. Folate is also found in peas, lentils, beans, eggs, yeast and liver. 綠葉蔬菜、蘆筍、花椰菜和橘子都富含葉酸，還是自然形式的葉酸。豌豆、扁豆、蠶豆、雞蛋、酵母和肝臟里都含有葉酸。
Studies have shown that many pregnant women get less folate in their diet than they need to prevent neural tube defects. So folic acid supplements are commonly recommended for pregnant women. Some countries add folic acid to flour. Norway does not do that. 研究還發(fā)現(xiàn)，許多孕婦飲食中含有的葉酸不足以預(yù)防神經(jīng)管缺損，因此，我們強(qiáng)烈建議孕婦服用葉酸補(bǔ)充劑，有的國家在面粉里加入葉酸，而挪威就沒有這么做。
