Neonatal mortality is a major health problem in sub-Saharan Africa and the risk factors are not well established. The objective of this study was to determine the risk factors for neonatal mortality at the Yaounde Gynaeco-Obstetric and Pediatric Hospital.
We conducted a retrospective and analytic case-control study from the medical records of newborns admitted at the neonatal unit of this hospital between 1(st) March 2003 and 31(st) December 2012. 850 subjects were enrolled; that is 425 cases and 425 controls. Findings : The intra-hospital neonatal mortality rate was 9.83%. The main causes of neonatal mortality were in descending order: neonatal sepsis (60.2%), complications from prematurity (42.6%), birth asphyxia (37.4%), and congenital malformations (11.8%).The most prominent risk factors for neonatal mortality after multivariate analysis with logistic regression were: prolonged membrane rupture (OR: 3.8719, 95% CI: 2.3619-6.3471; P=0.0000), low birth weight (OR: 1.6240, 95% CI: 1.0108-2.6091; P=0.0450), Apgar score less than 7 at the 5th minute (OR: 6.8979, 95% CI: 4.0709-11.6883; P=0.0000), and congenital malformations (OR: 4.3307, 95% CI: 1.6120-11.6347; P=0.0037). Delivery by cesarean section (OR: 0.2644, 95% CI: 0.1478-0.4732; P=0.0000) and being born in this hospital (OR: 0.4409;95% CI: 0.2566-0.7576; P=0.0030) were protective.
Neonatal mortality was influenced by both maternal and neonatal factors. This could be reduced through sensitization of pregnant women on the need of good quality antenatal visits, and capacitating the health personnel on the adequate management of high risk neonates.
新生儿死亡率是撒哈拉以南非洲地区的一个主要健康问题,其风险因素尚未完全明确。本研究的目的是确定雅温得妇产科和儿科医院新生儿死亡的风险因素。
我们对2003年3月1日至2012年12月31日期间在该医院新生儿科住院的新生儿病历进行了一项回顾性分析病例对照研究。共纳入850名受试者,即425例病例和425例对照。结果:院内新生儿死亡率为9.83%。新生儿死亡的主要原因依次为:新生儿败血症(60.2%)、早产并发症(42.6%)、出生窒息(37.4%)和先天性畸形(11.8%)。多因素逻辑回归分析后,新生儿死亡最显著的风险因素为:胎膜早破时间延长(比值比:3.8719,95%置信区间:2.3619 - 6.3471;P = 0.0000)、低出生体重(比值比:1.6240,95%置信区间:1.0108 - 2.6091;P = 0.0450)、第5分钟阿氏评分低于7分(比值比:6.8979,95%置信区间:4.0709 - 11.6883;P = 0.0000)和先天性畸形(比值比:4.3307,95%置信区间:1.6120 - 11.6347;P = 0.0037)。剖宫产分娩(比值比:0.2644,95%置信区间:0.1478 - 0.4732;P = 0.0000)和在本院出生(比值比:0.4409;95%置信区间:0.2566 - 0.7576;P = 0.0030)具有保护作用。
新生儿死亡率受母亲和新生儿因素的双重影响。可通过提高孕妇对高质量产前检查必要性的认识,以及增强医护人员对高危新生儿的妥善管理能力来降低该死亡率。
