The present study highlights the maternal age as an important factor related to death, especially in case of early or late motherhood. Therefore, based on the evidence that there would be higher risks of infant mortality for mothers of very young children (below 20 years) and for those 35 years and above, the aim of this thesis is to identify the relationship between maternal age and early neonatal, neonatal and post-neonatal mortality in the absence of any other variable and in the presence of their other associated factors such as maternal characteristics of the newborn, and health care of women and children. To reach the proposed objectives, we used the database of the National Demographic and Health Survey, 2006 (PNDS 2006). Regarding statistical analysis, Poisson regression models were used and prevalence ratios were estimated in order to verify the relationship between early neonatal, neonatal and post-neonatal death and associated factors selected on the basis of PNDS 2006. We analyzed 6,054 cases of singleton births between 2001 and 2007. Univariate analyzes were first conducted, having as dependent variable the occurrence / non occurrence of death for each period of interest (early neonatal, neonatal and post-neonatal); next, seven multivariate models were built based on the addition of demographic characteristics (age of mother and sex of the child), maternal reproductive history, the newborn, aspects of care and quality of care received by mothers during the prenatal and delivery, and information on complications in pregnancy or in childbirth. It was found that early maternal age was associated with death only in the post-neonatal period (PR = 2.48, p <0.10). However, such effect was not after controlling for duration of pregnancy and birth weight. In the case of advanced maternal age, the results revealed statistically significant effects in all segments of infant mortality. Therefore, factors related to prenatal care and childbirth still remain as a challenge to be faced in Brazil.
