title: Asthma mortality in Uruguay, 1984-1998.
abstract: BACKGROUND
  Asthma mortality rates have increased worldwide during the past several years despite the increased availability of new and effective medications. Few studies show reliable data from Latin American countries.
  
  
  OBJECTIVE
  To determine asthma mortality rates from 1984 to 1998 and to relate mortality to sales of asthma medications.
  
  
  METHODS
  We conducted a retrospective epidemiologic study in the total population of Uruguay. Data were obtained from the Department of Statistics of the Ministry of Public Health. Trends in mortality rates were analyzed using linear regression procedures. Spearman rank correlations were used to relate mortality rates to sales of asthma medications.
  
  
  RESULTS
  The mean overall mortality rate was 5.10 per 100,000 during the period 1984 to 1998, (range 6.08 to 3.39) and showed a decreasing trend (P = 0.001). During the period 1995 to 1998, a more pronounced decrease was observed (mean mortality rate, 4.10 per 100,000). In the 5- to 34-year-old age group the mean mortality rate was 0.43 (range 0.65 to 0.13). Similarly, the mortality rate in this age group decreased particularly in the 1994 to 1998 period (mean 0.19; P = 0.005). Finally, the mortality rate was inversely correlated with sales of inhaled corticosteroids; for the overall mortality rate, p = -0.71, P = 0.003; for 5- to 34-year-old age group, p = -0.63, P = 0.01.
  
  
  CONCLUSIONS
  Although mortality attributable to asthma seems to be decreasing, the overall mortality rate is still high compared with more economically developed countries. A more pronounced decrease in asthma mortality has been seen in the 5- to 34-year-old group. At present, Uruguay is a Latin American country with a low rate of asthma mortality. This is probably related to the use of new therapies to treat asthma.
