低体重婴儿的发生率和死亡率在美国比在欧洲国家更常见,针对这种情况,美国采取的改善措施之一就是使孕妇更容易得到产前保健。据报道在欧洲比在美国,孕妇更容易得到产前保健,然而,还没有足够的报道能够说明欧洲孕妇比美国孕妇运用产前保健措施更普遍。在欧洲产前保健的有关资料没有按期的公开报道,美国也是如此。在研究中,我们用欧洲人口调查的方法测算了美国、法国、丹麦、比利时等国家对产前保健的应用率,美国在1980年进行的国家民族调查中也曾采用过这种调查方法。 In the United States, where the prevalence and mortality of low-birth-weight babies are more common than in European countries, one of the improvements that the United States has taken is to make it easier for pregnant women to have antenatal care. It is reported that prenatal care is more accessible to pregnant women in Europe than in the United States, however, there are not enough reports to show that pregnant women in Europe are more prevalent than pregnant women in the United States. The information on antenatal care in Europe is not publicly available on a regular basis, as is the United States. In the study, we used the European census method to estimate the rate of prenatal care in the United States, France, Denmark, Belgium and other countries. The survey was also adopted by the United States in the 1980 national ethnographic survey.
