Matching 471 Oregon birth certificates with official Indochinese arrival lists reveals a fertility rate of 126.7, 1.8 times the US rate of 68.5. Greater maternal and infant risk rates were noted, particularly for Hmong. Data indicate improvements in obtaining prenatal care and in reducing the number of low birth weight infants for refugees who have resided in the US three or more months: however, the improvements appear to be reversed after 12 months of US residency.
将471份俄勒冈州出生证明与官方的印度支那移民名单进行比对后发现,生育率为126.7,是美国68.5这一生育率的1.8倍。研究发现孕产妇和婴儿的风险率更高,尤其是苗族。数据表明,对于在美国居住三个月或更长时间的难民来说,在获得产前护理以及减少低体重儿数量方面有所改善;然而,在美国居住12个月后,这些改善似乎出现了逆转。
