Table 1, Table 2 and Table 3 show all studied variables and those that were selected for the multivariate logistic regression analysis with a p-value < 0.20. In Table 4, after adjusting for other socioeconomic variables, those that had a higher chance of neonatal

death were households with no children under 5 years of age and with fewer than four residents. The variables of Sections 2 and 3 that remained significant were mothers with a history of previous deaths of children in the first year of life and hospitalization during pregnancy, respectively. In Section DZNeP 4, the variables inadequate prenatal care, lack of echocardiography, newborn transferred to another health facility, and the longest time between hospitalization and childbirth were significant for the occurrence of death. In Section 5, NICU admission and low birth weight remained statistically associated with increased odds of neonatal death. There was a higher concentration of deaths during the first 6 days of life, with more than one-third of deaths on the first day of life. Neonatal deaths in the first 6 days are mainly caused by maternal factors and pregnancy and childbirth complications.6 Studies have confirmed the association

of these deaths with poor prenatal care and inadequate care to newborns in the Selleckchem ABT263 delivery rooms of hospitals.3, 16 and 17 Almost two thirds of the studied families had low income (less than two Brazilian minimum wages per month). The association of low individual socioeconomic status and risk of neonatal death has shown diverse results in analytical

studies in Brazilian cities.3, 18, 19, 20, 21, 22, 23 and 24 Family income, maternal education, and age were not Edoxaban shown to be risk factors for neonatal mortality in this study. Similar results were found in studies that used the same method,2 and 3 possibly because most of the mothers interviewed in this study were SUS users with homogenous household income and level of education between cases and controls. Mortality during the neonatal period is more influenced by the care given to the mother and child during pregnancy and childbirth, whereas mortality in the post-neonatal period is more related to socioeconomic status and, more specifically, to quality of life.10 Families with the lowest number of household members and absence of children under five years of age were associated with a higher chance of neonatal death, a result similar to that found in São Luís (MA), Northeastern Brazil, a city with a similar socioeconomic status to the city of Maceió.25 Mothers who lived with more household members to help with child care and mothers with more experience were the arguments used by the authors to explain this finding.
