[Infant mortality in Brazil during recent periods of economic crisis].
OBJECTIVE
To analyze time trends in infant mortality in Brazil during a recent period of economic crisis (1980-1998).


METHODS
Time-series study based on the Ministry of Health's Mortality Information System, IBGE Foundation and Funda  o Nacional de Sa de (National Health Institute database. Serial parameters were described using autoregressive integrated moving average (ARIMA) models, and the association between infant mortality rates and a number of determinants was evaluated using Spearman correlation coefficients.


RESULTS
Infant mortality showed a declining trend (-59.3%) and a strong correlation with most of the indicators analyzed. However, only correlations between infant mortality rate and total pregnancy and birth rates presented a significant difference between the two decades.


CONCLUSIONS
Variations in pregnancy rate were the main cause for the persistent decline in infant mortality in the 1980's. In the subsequent period, causes related to living conditions, especially healthcare, may have been more important.
