MONTEIRO, Carlos Augusto. A contribution to the study of the significance of the trends in infant mortality rates for the city of S. Paulo, Brazil, during the last three decades (1950-1979). Rev. Saúde Pública [online]. 1982, vol.16, n.1, pp. 7-18. ISSN 0034-8910. http://dx.doi.org/10.1590/S0034-89101982000100002.
The possible correlations between infant mortality statistics and those, first, on the real value of the legal minimum salary and, sencondly, on the extent of the public water-supply system, for the city of S. Paulo (Brazil) over the last three decades, were studied with a view to determining the relationship between the historical trends in the infant mortality rates and in the quality of life. The abovementioned factors - salary and water-supply - are taken as factors of greater and lesser relevance, respectively, for the overall picture of the living conditions of the population. The mortality decline in the 50s and its increase in the 60s were found to be related, significantly, to the trends in the real value of the legal minimum salary. However, the trend in mortality in the 70s, with a notable fall as from 1974, was found to be related specifically to the trends in water-supply extension. One may conclude that in the period 1950-1979 the implications, relating to the quality of life, to be drawn from infant mortality trends are diverse. It would seem to be mistaken to affirm that the reversal of the high mortality rate as from 1974 might signify an identical reversal of the deterioration of living conditions which led to the increase of mortality in the preceding period.
