[Epidemiological observations on the evolutive tendency of asthma mortality in Spain]

We have studied asthma mortality in Spain from 1951 to 1985, applying epidemiological descriptive methodology. A global decrease in the tendency is observed when comparing it to other countries. We have observed, however, an increased mortality in the four age groups proposed (5-19, 5-39, 40-64 and 5-64), based on previous international publications which avoid interferences with other causes of death. We have also observed that when applying the method of mortality related to natality rate, there was a decrease in mortality, specially in older generations. Finally, several hypothesis related to risk factors which would explain this tendency are presented.
