目的：在本文中，我们研究了收入和教育相关的不平等，小于胎龄（SGA）和早产在丹麦和芬兰从1987年至2003年使用集中指数（CIX）。方法：我们从国家医疗出生登记处收集了1987年至2003年所有出生的信息。在丹麦和芬兰，分别获得了1 012 400名和499 390名新生儿在子女出生前一年中完成的最高母亲教育和家庭收入的信息。然后，我们计算了SGA和早产中收入和教育相关不平等的CIX。结果如下：SGA中平均家庭收入相关不平等在丹麦为-0.04（95%置信区间：-0.05，-0.04），在芬兰为-0.03（-0.04，-0.02）。SGA中与母亲教育相关的不平等在丹麦为-0.08（-0.10，-0.06），在芬兰为-0.07（-0.08，-0.06）。早产方面与收入有关的不平等在丹麦为-0.03（-0.03，-0.02），在芬兰为-0.03（-0.04，-0.02）。在丹麦和芬兰，与教育有关的早产不平等分别为-0.05（-0.07，-0.04）和-0.04（-0.05，-0.03）。在丹麦，SGA中与收入和教育相关的不平等随着时间的推移而增加。在芬兰，与收入有关的SGA出生不平等略有增加，而与教育有关的不平等保持稳定。随着时间的推移，这两个国家的早产不平等现象有所减少。结论：丹麦和芬兰是提供免费产前护理和公共资助的高质量产科护理的国家。在研究期间，两国都受到宏观经济冲击的影响。然而，在此期间，仅观察到与收入和教育有关的小规模出生缺陷和早产不平等。
Aims: In this paper, we examine income-and education-related inequality in small-for-gestational age (SGA) and preterm birth in Denmark and Finland from 1987 to 2003 using concentration indexes (CIXs). Methods: From the national medical birth registries we gathered information on all births from 1987 to 2003. Information on highest completed maternal education and household income in the year preceding birth of the offspring was obtained for 1,012,400 births in Denmark and 499,390 in Finland. We then calculated CIXs for income-and education-related inequality in SGA and preterm birth. Results: The mean household income-related inequality in SGA was -0.04 (95% confidence interval: -0.05, -0.04) in Denmark and -0.03 (-0.04, -0.02) in Finland. The maternal education-related inequality in SGA was -0.08 (-0.10, -0.06) in Denmark and -0.07 (-0.08, -0.06) in Finland. The income-related inequality in preterm birth was -0.03 (-0.03, -0.02) in Denmark and -0.03 (-0.04, -0.02) in Finland. The education-related inequality in preterm birth was -0.05 (-0.07, -0.04) in Denmark and -0.04 (-0.05, -0.03) in Finland. In Denmark, the income-related and education-related inequity in SGA increased over time. In Finland, the income-related inequality in SGA birth increased slightly, while education-related inequalities remained stable. Inequalities in preterm birth decreased over time in both countries. Conclusions: Denmark and Finland are examples of nations with free prenatal care and publicly financed obstetric care of high quality. During the period of study there were macroeconomic shocks affecting both countries. However, only small income-and education-related inequalities in SGA and preterm births during the period were observed.
