    Abstract:
    BACKGROUND: Perinatal clinical picture allows identifying psychosocial features in pregnant women, them medical, obstetrical, and pregnancy history, present delivery, and neonatal mortality risk factors. OBJECTIVE: To know prevalence of maternal risk factors and evaluates them impact on neonatal mortality. MATERIALS AND METHODS: A cohort of 25,365 live newborns was studied between January 1st 2000 and December 31st 2004. Maternal sociodemographic and obstetrical history was registered in a database; as well as weight, gestational age, and neonate discharge condition. Dead neonates were considered cases and controls those discharged alive. Mortality was compared with maternal history. Prevalence, odds ratio (OR) with 95% confidence interval, and exposed and population attributable fraction were calculated with the SPSS 8.0 and Epi Info 6.4 applications. RESULTS: Maternal factors associated with newborn mortality were: maternal age > or = 30 years OR 1.5 (1.37-2.0), less than seven prenatal consultations OR 2.17 (1.52-3.09), 53.5% of attributable fraction in exposed and 23.3% in population, eclampsia OR 4.66 (2.82-7.64), type 2 diabetes OR 5.41 (2.11-12.99), urinary tract infection OR 1.98 (1.40-2.78), positive serology to HIV OR 41.75 (5.77-230.9), membrane rupture > or = 48 hours OR 22.99 (13.10-40.2), polyhydramnios OR 31.53 (19.12-51.6) and premature separation of the placenta OR 42.18 (21.06-83.1). CONCLUSIONS: Risk factors history during delivery has a larger impact on mortality than pregnancy or pregestational factors.
