Resumo
OBJECTIVE: To identify the spatial distribution patterns and areas of higher risk of preventable
perinatal mortality in the city of Salvador, State of Bahia, Brazil.
METHODS: We carried out a spatial aggregated study in 2007, considering the weighting
areas (census tracts contiguous sets) of Salvador, of which the center and north present low
life conditions. Data were obtained from national vital statistics systems and the 2010 Census.
Addresses of live births and stillbirths were geocoded by weighting area. The spatial distribution of
the perinatal mortality rate was analyzed from thematic maps. Spatial dependence was evaluated
by the Global and Local Geary’s and Moran’s Indexes.
RESULTS: Crude and smoothed perinatal mortality rates were high in areas situated to the north,
west, and in center of Salvador. The smoothed rates in weighting areas ranged from 4.9/1,000 to
22.3/1,000 births. Of all perinatal deaths, 92.1% could have been prevented. We identified spatial
dependence for preventable perinatal mortality for care in pregnancy, with neighboring areas
with high risk in the north of the city.
CONCLUSIONS: The preventability potential of perinatal mortality was high in Salvador, in 2007.
The spatial distribution pattern with higher rates in disadvantaged areas of the city suggests the
existence of social inequalities in health. The characteristics of the process of urban development
of Salvador, which has inadequate prenatal care, possibly influenced the magnitude and spatial
distribution pattern of this mortality.
