美国研究称双酚A或与婴儿哮喘相关联

　　据外媒报道，早先有研究证明，双酚A与小白鼠患哮喘相关联，然而相关的人体试验尚未展开，本周召开的儿科研究学会(Pediatric Academic Societies)年会公布的一项研究显示，孕妇在妊娠早期受双酚A影响可能会导致婴儿感染哮喘。

　　美国研究人员以367名受试孕妇为研究对象，研究了孕妇体内双酚A水平与婴儿哮喘发病率的关系。他们发现，在婴儿6个月大时，体内双酚A水平较高的孕妇所生的婴儿患哮喘的几率是双酚A水平低孕妇所生婴儿的两倍。然而在婴儿3周岁时，两组孕妇所生的婴儿患哮喘的几率无差异。该研究还发现，孕妇在怀孕16周时，体内较高水平的双酚A与其所生婴儿患哮喘相关联，然而在怀孕26周时，二者便无关联。

　　然而，研究人员还表示，双酚A与哮喘的关系还需进行更多的研究。

　　Study links BPA exposure to wheezing in babies

　　A study presented this week at the annual meeting of the Pediatric Academic Societies has indicated that exposure to the chemical bisphenol A during early pregnancy may be associated with wheezing in children.

　　US researchers found that at six months the odds of wheezing are twice as high for children with mothers who had higher BPA than those who had mothers with lower BPA levels in the 367 subjects studied. However, no differences in wheezing rates were found by 3 years of age. The study also found that high BPA levels detected in women at 16 weeks' gestation were associated with babies that wheezed, but high levels at 26 weeks' gestation and birth were not.

　　Exposure to BPA during development has previously been associated with asthma in mice, but studies in humans are lacking. The scientists believe that more research is needed to study the correlation between BPA and wheezing in children.
