To examine, nationwide, if there is an association between country of birth in mothers and preterm birth and to study whether any such association remains in second-generation immigrant women. In this follow-up study, a nationwide research database located at Lund University, Sweden, was used to identify all preterm born singletons in Sweden between January 1, 1982, and December 31, 2006. Incidence ratios were standardized with regard to maternal age at birth, marital status, geographical region, body height, and smoking history as well as period of birth, family income, and gender of the infant. Singletons of mothers born in Sweden were used as the reference group. There were 2,192,843 records for singletons over the study period, of whom 4.9 % were preterm births and 0.8 % were very preterm births. Increased risk of preterm birth was observed for mothers from Austria, Yugoslavia, Romania, Central Europe, and Asia. Increased risk of very preterm birth was observed for mothers from Eastern Europe, Central Europe, Africa, and Asia; these increased risk disappeared, however, in the second-generation female immigrants. Country of birth in mothers affected the risk of preterm birth; maternity care should pay special attention to women from certain population groups.
本研究旨在全国范围内探讨母亲出生地与早产之间的关系，并研究这种关联是否在第二代移民女性中仍然存在。在这项随访研究中，研究人员利用位于瑞典隆德大学的全国性研究数据库，确定了 1982 年 1 月 1 日至 2006 年 12 月 31 日期间在瑞典出生的所有早产单胎婴儿。通过标准化产妇的出生年龄、婚姻状况、地理位置、身高和吸烟史以及出生时期、家庭收入和婴儿性别，计算出发病率比值。将在瑞典出生的母亲所生的单胎婴儿作为参考组。在研究期间，共有 2192843 名单胎婴儿的记录，其中 4.9%为早产，0.8%为极早产。来自奥地利、南斯拉夫、罗马尼亚、中欧和亚洲的母亲所生婴儿早产的风险增加。来自东欧、中欧、非洲和亚洲的母亲所生婴儿极早产的风险增加；然而，在第二代女性移民中，这种风险消失了。母亲的出生地影响早产的风险；产妇保健应特别关注来自某些人群的女性。
