The new study in pregnant women who were not infected with the AIDS virus found that multivitamins reduced the risk of low birth rateweight. 对没有感染爱滋病的孕妇的一项新研究表明，多维他命片可以减少生低体重儿的风险。
The results showed that women with IBD were almost twice as likely to have a child born prematurely, and more than twice as likely to have a child born below normal weight. 结果显示炎症性肠炎的妇女大约会有两倍的几率早产，有大于两倍的几率有低体重儿。
