Abstract
OBJECTIVEThe aim of this study was to identify spatial patterns of distribution of overall, early, and late neonatal mortality rates in São Paulo state. METHODSAn ecological and exploratory study was carried in micro-regions of São Paulo sate. Mortality rates per 1,000 live births (LB) were calculated using data on overall, early, and late neonatal mortality in São Paulo between 2006 and 2010; these data were obtained from Information System and Information Technology Department of the Brazilian National Healthcare System (DATASUS). The global Moran's indices (I) were calculated for rates and thematic maps were built with these rates. Micro-regions with a high priority for intervention were identified by the box map. The software TerraView 4.2.1 was used for spatial analysis. RESULTSThe rates of early and late neonatal mortality were 6.2 per thousand LB and 2.5 per thousand LB, respectively. The global Moran's indexes (I) were I=0.13, I=0.15, and I=0.26 for overall, early, and late neonatal mortality rates, respectively; all global Moran's indices showed P-values <0.05. Thematic maps showed clusters of micro-regions with high rates located in the southwest and east of the state. CONCLUSIONThe results presented in this study allow the implementation of policies by health managers, aiming to reduce neonatal mortality.
