在瑞典,几乎所有怀孕妇女都系安全带。但是她们并不知道,为了以最佳方式保护胎儿,安全带应该系在哪个部位最合适。这让她们很不安。瑞典哈尔姆斯塔德大学生物机械系的研究人员最近就这个课题进行了研究。研究人员的第一项工作是向一组孕妇发放问卷,然后对她们进行个别采访。在回答问卷的139位妇女中,除1位之外,都说她们在怀孕之前坚持系安全带。其中7位处于妊娠期最后阶段的妇女说,现在她们较少使用安全带,这么做的理由是害怕安全带会危害胎儿的安全,而且很难系上安全带。2000年,美国的研究人员曾对200位研究对象进行过类似调查。大部分调查对象也说系安全带让她们感到不舒服,容易擦伤皮肤,而且往上移动。在瑞典和美国进行的对孕妇系安全带情况的调查结果对比如下:
In Sweden, almost all pregnant women wear seat belts. But they do not know where the seat belts should fit best to protect the fetus in the best possible way. This makes them very restless. Researchers at the Department of Biomechanics, University of Halmstad, Sweden, recently conducted a research on this subject. The first job of a researcher is to send a questionnaire to a group of pregnant women and then interview them individually. Of the 139 women who answered the questionnaire, all but one said they insisted on wearing seat-belts until they became pregnant. Seven women, who are in the final stages of pregnancy, say they now seldom use seat belts because they fear the safety of the seat belts and make it harder to wear seat belts. In 2000, researchers in the United States conducted a similar survey of 200 subjects. Most respondents also said that seat belts make them feel uncomfortable, easy to scratch the skin, and move up. The findings of a survey of seat belts for pregnant women carried out in Sweden and the United States are as follows:
