Early neonatal mortality and risk factors: a case-control study in Paraná State

ABSTRACT Objective: to analyze the Early Neonatal Mortality risk factors according to the risk stratification criteria of the Guideline of the Rede Mãe Paranaense Program. Method: a case-control epidemiological study with secondary data from the Mortality and Live Birth Information System in 2014. The crude analysis was performed by the Odds Ratio association measure, followed by the adjusted analysis, considering risk factors as independent variables, and early neonatal death as dependent variable. Results: were considered as maternal risk factors: absence of partner and miscarriages; neonatal: male, low birth weight, prematurity, Apgar less than seven in the fifth minute, presence of congenital anomaly; and care: up to six prenatal appointments. Conclusion: an innovative study of risk factors for early neonatal death from the Guideline's perspective, a technological management tool for maternal and child health, in search of its qualification and greater sensitivity.

摘要 研究目的：依据巴拉那州母亲网络项目（Rede Mãe Paranaense Program）指南的风险分层标准，分析早期新生儿死亡的危险因素。研究方法：采用病例对照流行病学研究设计，使用2014年死亡与活产信息系统的二手数据。粗分析采用比值比（Odds Ratio）作为关联度量指标，随后以危险因素作为自变量、早期新生儿死亡作为因变量开展校正分析。研究结果：本次纳入分析的危险因素包括：产妇相关危险因素：无配偶、有流产史；新生儿相关危险因素：男性、低出生体重、早产、第5分钟Apgar评分低于7分、存在先天性畸形；以及产科护理相关危险因素：产前检查次数不超过6次。研究结论：本研究从作为妇幼保健技术管理工具的该指南视角出发，针对早期新生儿死亡危险因素开展了创新性研究，旨在推动相关工作的规范化与筛查敏感度的提升。
