The objective of this study was to identify risk factors associated with pre-term birth among live births in a hospital in Londrina, Paraná State, Brazil. Cases consisted of 328 pre-term births, and controls were 369 births with gestational age greater than 37 weeks. A multiple hierarchical logistic regression analysis was carried out. There was a significant correlation (p < 0.05) between pre-term birth and the following variables: socioeconomic status (slum residence); low age of head-of-family; maternal BMI < 19 or > 30 kg/m2; history of prematurity; history of assisted reproduction; mothers in a relationship for less than two years; maternal stress; weekly maternal alcohol consumption; insufficient prenatal care; gestational complications such as bleeding, genital tract infection, altered amniotic fluid volume, high blood pressure, and hospital admission; and twin pregnancy. Regular walks during pregnancy were a protective factor. Improved quality of prenatal care and the identification of the above factors during pregnancy may help reduce premature birth.
本研究的目的是确定巴西巴拉那州隆德里纳市一家医院活产儿中与早产相关的风险因素。病例包括328例早产，对照为369例孕周大于37周的分娩。进行了多元分层逻辑回归分析。早产与以下变量之间存在显著相关性（p<0.05）：社会经济地位（居住在贫民窟）；户主年龄低；母亲BMI<19或>30kg/m²；早产史；辅助生殖史；恋爱关系少于两年的母亲；母亲压力；母亲每周饮酒量；产前护理不足；妊娠并发症，如出血、生殖道感染、羊水过少、高血压和住院；以及双胎妊娠。孕期定期散步是一个保护因素。改善产前护理质量以及在孕期识别上述因素可能有助于减少早产。
