title: [Neonatal mortality and avoidable causes in the micro regions of São Paulo state].
abstract: OBJECTIVE
  To identify spatial patterns of neonatal mortality distribution in the micro regions of São Paulo State and verify the role of avoidable causes in the composition of this health indicator.
  
  
  METHODS
  This ecological exploratory study used neonatal mortality information obtained from Information System and Information Technology Department of the Brazilian National Healthcare System (DATASUS) in the period between the years 2007 and 2011. The digital set of micro regions of São Paulo State was obtained from Instituto Brasileiro de Geografia e Estatística (IBGE). Moran Indexes were calculated for the neonatal mortality total rate and rate from avoidable causes; thematic maps were constructed with these rates, as well as the difference between them; and the Box Map was built.
  
  
  RESULTS
  The overall neonatal mortality rate was 8.42/1,000 live births and neonatal mortality rate from avoidable causes of 6.19/1,000 live births. Moran coefficients (I) for these rates were significant (p-value<0.05) - for the total rate of neonatal mortality I=0.11 and for mortality from preventable causes I=0.19 -, and neonatal deaths were concentrated in southwest region and the Vale do Paraíba. If preventable causes were abolished, there would be a significant reduction in the average rate of overall neonatal mortality, from 8.42 to 2.23 deaths/1,000 live births, representing a decline of 73%.
  
  
  CONCLUSIONS
  This study demonstrated that neonatal mortality rate would be close to the rates of developed countries if avoidable causes were abolished.
