Abstract
Objective
Describe the behavior of the incidence of Aids in the group of 50-year-old people and more, in Brazil and its macro-regions, from 1990 to 2003, analyzing the previous and subsequent moment of introduction of medicines for erectile dysfunction in the country, in 1998.
Methods
An ecological study was carried out, along with a space-time analysis of the notified cases of Aids in this group of people. Models of linear regression, adjusted to the time series of Aids cases whose diagnoses date from 1990 to 1997, provided the taxes of annual average variation, as well as the expected values, so making it possible to compare incidence taxes observed and estimated from 1998 to 2003.
Results
25,223 cases of Aids in the group of 50-year-old people and more had been analyzed, being the majority (84%) in the Southeast and South regions. Those regions also presented the greatest taxes of annual average variation to the year of 1997 (1.002 and 0.906, respectively), followed by the Middle-West (0.570), North (0.441) and Northeast (0.254); Brazil showed a tax of 0.588. After 1998, the comparison of the taxes accumulated from 1998 to 2003 revealed the expected higher trends than the ones observed in all regions, except for the Northeast.
Conclusion
The trend of growth of Aids in the 50-year-old people and more group presented greater taxes of growth from 1990 to 1997, and this growth remained in the period subsequent to the introduction of medicines for erectile dysfunction, but more slowly.
