OBJECTIVES: To analyze trends in morbidity due to @entity1576 , using hospital admissions in the city of S  o Paulo from 1995 to 2000. To describe the evolution of the morbidity for @entity1576 in general and for @entity55 , for @entity565 and for @entity1030 ( @entity1030 ), by sex and age. METHODS: The information on hospital admissions for all ages and causes were obtained from the Hospitalizations Information System of the Brazilian Ministry of Health (DATASUS). Descriptive analysis of patterns and trends were performed. RESULTS: There was a decreasing trend in the absolute number and the rate of hospitalization for respiratory illnesses for all ages but not uniformly during the period. For @entity1030 , an increasing trend was observed, especially for the elderly. The male population was more affected than the female in all years, for any studied causes with the exception of @entity565 . The @entity55 represented the most important cause of hospitalizations, with 47% of all respiratory admissions. Important seasonal pattern was observed for @entity55 admissions. CONCLUSION: In this period of 6 years, our analyses had disclosed an important participation of @entity55 as a cause for respiratory admissions. However, these diseases presented a decreasing trend, in contrast to @entity102 such as @entity1030 and @entity565 . These results point out to a changing pattern in the @entity1576 with direct consequences for public health policy making.
