MONTEIRO, Carlos Augusto. An estimate of the specific infant mortality rates by birth-weight in the city of S. Paulo (Brazil). Rev. Saúde Pública [online]. 1981, vol.15, n.6, pp.603-610. ISSN 1518-8787.

By means of the birth-rate distribution found to exist during the Inter-American Investigation of Mortality in Childhood in S. Paulo (1968-70) the infant death rate association with each birth-weight interval was estimated. The infant mortality rates were 305.5, 50.2 and 34.4 respectively for low birth-weight, deficient weight and weight above 3,000 grams. Compared with the rates found in California, USA, by the same Investigation, the infant mortality rates in S. Paulo are higher, particularly for mortality associated with birth-weight of above 3,000 grams. The adjustment of infant mortality rates in S. Paulo according to the birth-weight distribution found in California led to the conclusion that, at that period, only 15% of the excess of the infant mortality of S. Paulo could be attributed exclusively to birth-weight. In the case of neonatal mortality, 21% of the mortality excess in S. Paulo could be attributed to birth-weight.
