早产是新生儿死亡的主要原因，也是影响高、中、低收入国家的全球健康问题。有几个因素可能会增加早产的风险。在这篇文章中，我们测试的假设，不同的危险因素决定早产在不同的收入群体，调查是否早产的危险因素在2004年Pelanmar（南里奥格兰德，巴西）出生队列中的不同群体。共有4，142名女性被纳入分析。早产在自然阴道分娩的妇女和引产或手术分娩的妇女中同样常见。在多因素分析中，仍然与早产显著相关的因素是黑皮肤、低教育、贫困、年轻的母亲年龄、第二次产次、以前的早产、产前护理不足和报告的高血压。在按家庭收入等级分层后重复分析中，没有证据表明收入对效果的影响，社会经济群体之间也没有明显差异。剖腹产和早产之间没有发现关联，需要进一步研究以了解巴西早产流行的原因。
Prematurity is a leading cause of neonatal mortality and a global health problem that affects high, middle and low-income countries. Several factors may increase the risk of preterm birth. In this article, we test the hypothesis that different risk factors determine preterm birth in different income groups by investigating whether risk factors for preterm deliveries in the 2004 Pelotas (Rio Grande do Sul State, Brazil) birth cohort vary among those groups. A total of 4,142 women were included in the analysis. Preterm births were equally common among women who had spontaneous vaginal deliveries as for those with induced or operative births. In the multivariate analysis the factors that remained significantly associated with preterm birth were black skin color, low education, poverty, young maternal age, primiparity, previous preterm birth, inadequacy of prenatal care and reported hypertension. In the analyses repeated after stratification by family income terciles, there was no evidence of effect modification by income and no clear difference between the socioeconomic groups. No association between cesarean section and preterm delivery was found. Further studies are required to understand the causes of the epidemic of preterm births in Brazil.
