【 摘 要 】

OBJECTIVE:To describe infant mortality in the State of São Paulo, in 1999, basedon multiple causes of death and to compare data from underlying and multiplecauses of death.
METHODS: Data came from 12,793 infant death records in 1999, of Seade Foundation(State Data Analysis System Foundation). Causes of death were coded accordingto the Tenth Revision of the International Statistical Classification of Diseasesand Related Problems and were classified into 28 meaningful groups for the purposeof this article. In order to analyze multiple causes of death, simple frequencieswere used in addition to principal components analysis to obtain the main groupsof causes that contributed to death.
RESULTS: The most frequent multiple causes of death were respiratory andcardiovascular diseases of the perinatal period (24.2% of all multiple causes),diseases related to growth and maturity of the fetus and the newborn (20.2%),congenital malformations (8.6%) and perinatal infections (7.6%). Principal componentsanalysis revealed three major interpretable components: "post-neonatal, infectiousand avoidable deaths", "complications of procedures and external causes" and"perinatal disorders, not related to low birth weight and/or immaturity".
CONCLUSION: By using principal components analysis it was easier to understandhow the multiple causes were associated. This is more interesting for PublicHealth purposes, because it may help clarify the steps in disease causation.
