Exposure to phthalates could be linked to pregnancy loss
A new study of more than 300 women suggests that exposure to certain phthalates could be associated with miscarriage, mostly between 5 and 13 weeks of pregnancy. The research is the first epidemiological study on non-work-related exposure to phthalates to provide evidence for the possible link among a general population.
Out of concern over the potential health effects of phthalates, the U.S. has banned six of these substances from use in certain products made for young children. But many are still included as ingredients in paints, medical tubes, vinyl flooring, soaps, shampoos and other items. But there is little epidemiological evidence of phthalates' effects on pregnancy among women with non-occupational exposure. Jianying Hu, Huan Shen and colleagues wanted to find out if there might be a link.
The researchers tested urine samples from 132 women who had miscarriages and 172 healthy pregnant women in China. They found pregnancy loss was associated with higher levels of urinary phthalate metabolites from diethyl phthalate (DEP), di-isobutyl phthalate (DiBP) and di-n-butyl phthalate (DnBP).
