Asthma mortality in Cuba during 1972-1993.

UNLABELLED

Morbi-mortality due to asthma has increased in recent years both throughout the world in Cuba. A study of mortality caused by this disease has conducted in order to describe its current trend in the country.

METHOD

A time series study was conducted which included all deaths attributed to asthma in Cuba recorded in the vital statistics records of the Ministry of Public Health from 1972 to 1993. Rates, secular trends of general mortality and according to gender were estimated. The proportional mortality for the 1972-1993 period was calculated and the potential years of life lost during the 90-92 trienium were quantified.

RESULTS AND DISCUSSION

A drop in these global rates occurred between 1972 and 1975, with values of 3.6; 4.1; 3.0; 2.2; respectively; possibly due to the introduction of disodic chromoglycate among other drugs and the beginning of the Asthmatic Patient Program. An later increase in mortality was observed until 1993 (5.9 x 100,000 inhabitants) which may attributed to a drop of the intensity and regularity of said program and to other internationally knowledge factors which are present in our country. The trend of general mortality rose during this period and was greater in females than in males; which means that the risk to die of this cause has increased. Proportional Mortality since 1980 (0.50%) also increased until 1993 (0.80%). Potential years of life lost due to premature death ranged from 5,646 in 1990 to 7,386 in 1992. The increase in proportional mortality and the potential years of life lost suggest that this disease should been given priority by the National Health Program as a preventable cause of death, especially in women.

CONCLUSIONS

There is a rising trend of mortality among asthmatic patients during the period under consideration. Asthma is a cause of premature death in Cuba.
