美國研究稱雙酚A或與嬰兒哮喘相關(guān)聯(lián)

　　據(jù)外媒報道，早先有研究證明，雙酚A與小白鼠患哮喘相關(guān)聯(lián)，然而相關(guān)的人體試驗尚未展開，本周召開的兒科研究學(xué)會(Pediatric Academic Societies)年會公布的一項研究顯示，孕婦在妊娠早期受雙酚A影響可能會導(dǎo)致嬰兒感染哮喘。

　　美國研究人員以367名受試孕婦為研究對象，研究了孕婦體內(nèi)雙酚A水平與嬰兒哮喘發(fā)病率的關(guān)系。他們發(fā)現(xiàn)，在嬰兒6個月大時，體內(nèi)雙酚A水平較高的孕婦所生的嬰兒患哮喘的幾率是雙酚A水平低孕婦所生嬰兒的兩倍。然而在嬰兒3周歲時，兩組孕婦所生的嬰兒患哮喘的幾率無差異。該研究還發(fā)現(xiàn)，孕婦在懷孕16周時，體內(nèi)較高水平的雙酚A與其所生嬰兒患哮喘相關(guān)聯(lián)，然而在懷孕26周時，二者便無關(guān)聯(lián)。

　　然而，研究人員還表示，雙酚A與哮喘的關(guān)系還需進行更多的研究。

　　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.
