RESUMO

Introduction - Infant mortality (IM) in São Paulo (MSP) has declined, especially from the 80s. However, there may be important regional differences between Districts as their socio-environmental characteristics may influence this indicator. Objective - To describe and analyze IM trend in the period from 2000 to 2007, according to the Districts of MSP. Method - Ecological longitudinal study comprising 31 units of analysis (Districts). Linear multilevel regression model was used for statistical analysis. Infant Mortality Rate (IMR) and eight years of observation (2000-2007) were used as dependent variables. The model included variables related to health services. Results The decrease in IM does not occur homogeneously between Districts as evidenced by the different slopes and intercepts of the observed and estimated lines. A multilevel model showed an 18.8% reduction in IM in the period with an average decline of 0,300/00 living born (lb) per year. According to the model, 51% of the IM variability can be explained by contextual features of districts. During the study period, IMR increases: 0,0560/00lb for every 1% increase among mothers with inadequate prenatal care, 0,2140/00lb for every 1% increase among users of the Unified Health System (UHS), 0,0390/00lb for each increase in the UHS obstetric beds rate. IMR decreases 0,1910/00lb for every 1% increase in the vitality proportion of recovery of live births. Conclusion - IM shows a declining trend over the period from 2000 to 2007 in a non-homogeneous way according to District. The variables that were associated with IMR: year of observation, proportion of live births from mothers who had up to 6 prenatal visits (inadequate prenatal care), Unified Health System (UHS) obstetric beds rate, proportion of UHS users and vitality recovery of live birth proportion. The highest IMR is found in peripheral region of MSP where the largest proportion of UHS users is found.
