The aim of the study was to estimate the occurrence of low birthweight (LBW) and preterm birth among immigrant and Swedish women in Sweden. Eligible for analysis were all 1,270,407 singleton births in Sweden between 1978 and 1990 to mothers aged between 15 and 44 years, whose own country of birth was known. The mothers of the children were born in Sweden (88.2%), or had immigrated from Finland (4.4%), other Scandinavian countries (1.2%), Western Europe or North America (1.3%), Eastern Europe (1.8%), the Middle East and North Africa (1.7%), Central and South America (0.6%), Asia and the Pacific Islands (0.6%), or Sub-Saharan Africa (0.2%). Multiple logistic regression was used to model LBW and preterm birth categorical outcomes. Each immigrant group was compared with the Swedish group. Odds ratios (ORs) for LBW were 1.13 (95% CI 1.04, 1.22) for Asia and the Pacific Islands, 1.21 (1.05, 1.38) for Sub-Saharan Africa and 0.89 (0.86-0.93) for Finland. Odds ratios for preterm birth were 1.15 (1.08-1.23) for immigrants from Asia and the Pacific Islands and 1.08 (1.04, 1.13) for immigrants from Eastern Europe. Remarkably small differences were found between immigrant women and native Swedish women.
该研究的目的是估计瑞典移民妇女和瑞典本土妇女中低出生体重（LBW）和早产的发生率。纳入分析的对象为1978年至1990年间在瑞典出生的、母亲年龄在15至44岁之间且出生地已知的所有1,270,407例单胎分娩。这些孩子的母亲出生在瑞典（88.2%），或从芬兰移民而来（4.4%）、其他斯堪的纳维亚国家（1.2%）、西欧或北美（1.3%）、东欧（1.8%）、中东和北非（1.7%）、中美洲和南美洲（0.6%）、亚洲及太平洋岛屿（0.6%）或撒哈拉以南非洲（0.2%）。采用多因素logistic回归对低出生体重和早产的分类结局进行建模。将每个移民群体与瑞典群体进行比较。亚洲及太平洋岛屿的低出生体重比值比（OR）为1.13（95%CI 1.04, 1.22），撒哈拉以南非洲为1.21（1.05, 1.38），芬兰为0.89（0.86 - 0.93）。亚洲及太平洋岛屿移民的早产比值比为1.15（1.08 - 1.23），东欧移民为1.08（1.04, 1.13）。移民妇女和瑞典本土妇女之间的差异非常小。
