The political economy of infant mortality in São Paulo, Brazil.

After the military took power in Brazil in 1964, the government adopted a wide range of policies designed to stimulate economic growth. A central aspect of the Brazilian model of development was the control of wages. From 1964 to 1975 this strategy caused the purchasing power of the minimum wage in the city of Säo Paulo to fall. The decline in the real wage index was associated with a rise in infant mortality during the period. When real wages rose after 1974, the death rate dropped off. The infant mortality trend cannot be explained by other factors that affect the actual or the reported death rate, such as changes in cityward migration, shifts in the distribution of income, and improvements in the quality of vital statistics. The findings of this study indicate a causal relationship between the infant mortality trend and changes in the purchasing power of the urban poor. Additional data on nutrition, changes in household behavior, and shifts in the cause structure of mortality support this conclusion.
