The aim of this study was to identify and analyze risk factors for perinatal mortality in Recife, Pernambuco State, Brazil, in 2003, using a multilevel hierarchical model. In this case-control study, cases consisted of all perinatal deaths in 2003 in singleton infants with birth weight > 500g and without congenital malformations. The controls were live births from December 26, 2002, to December 31, 2003, with the same characteristics as the study group, but who survived > 6 days. By using record linkage techniques, 403 cases and 1,612 controls were obtained. All variables, when submitted jointly to multiple logistic regression, showed statistical significance in decreasing order of risk, as follows: prematurity (OR = 18.23), low birth weight (OR = 4.90), maternal age > 35 (OR = 1.97), delivery in public hospitals (OR = 1.93), and maternal schooling < 4 years (OR = 1.78).
本研究旨在运用多层次分层模型，识别并分析2003年巴西伯南布哥州累西腓市围产期死亡率的风险因素。在这项病例对照研究中，病例组包括2003年出生体重>500克且无先天性畸形的单胎婴儿中的所有围产期死亡病例。对照组为2002年12月26日至2003年12月31日出生、具有与研究组相同特征但存活>6天的活产婴儿。通过记录链接技术，获得了403例病例和1612例对照。所有变量在联合进行多因素逻辑回归分析时，按风险递减顺序显示出统计学意义，具体如下：早产（比值比=18.23）、低出生体重（比值比=4.90）、母亲年龄>35岁（比值比=1.97）、在公立医院分娩（比值比=1.93）以及母亲受教育年限<4年（比值比=1.78）。
