Infant mortality rate and social disparity at Recife, the metropolis of the North-East of Brazil

We analyzed differences in infant mortality between areas of Recife, a city in the North East of Brazil, analyzing the relationship between living conditions and the risk of death. We compared infant mortality coefficients for 1995 with indicators of living conditions and collected data for the 770 infant deaths and the 27,965 live births. Neighborhoods were ranked according to the quality of living conditions and were grouped into four clusters. The infant, neonatal and postneonatal mortality coefficients were 27.53, 18.84 and 8.69 per 1,000 live births respectively. Lower quality living conditions were associated with higher coefficients. The main causes of infant deaths were perinatal disorders, the coefficient of which was 14.95 per 1,000 live births, followed by congenital malformations, gastroenteritis and bronchopneumonia. With the exception of congenital malformations, the coefficients of all these causes of death increased as living conditions worsened. These inequalities are generally obscured by the presentation of means for the city as a whole.
