[Aids as underlying and associated causes of death, State of S. Paulo, Brazil, 1998]

Abstract

Objectives: To describe the Aids mortality according to its underlying and associated causes of death in the State of S. Paulo in 1998.

Methods: Mortality and population data for 1998 were obtained from the State Data Analysis System Department (Fundação Sistema Estadual de Análise de Dados - Seade). Causes of death were coded according to the Tenth Revision of the International Statistical Classification of Diseases and Related Health Problems.

Results: Aids was the underlying cause in 4,619 deaths, corresponding to the 10th leading cause of death (2.0%) and a mortality rate of 13.1/100,000 population. Male/female death ratio and rate ratios were respectively 2.4 and 2.5. Aids was the second leading cause of death among men aged 20--34 and women aged 25--34 years. Median age at death for women (34.1+/-12.2 years old) was lower than men (36.4+/-10.7 years old) - p<0,001. The main associated causes of Aids deaths were respiratory insufficiency (36.1%), pneumonia (27.0%), tuberculosis (19.6%), septicemia (18.6%), toxoplasmosis (12.2%), P. carinii pneumonia (8.3%) and cachexia (7.9%). Aids was an associated cause of death in additional 84 cases. The main underlying causes of these deaths were malignant neoplasms (28/84), conditions secondary to alcohol abuse (23/84) and diabetes mellitus (7/84). The median age at death due to Aids as an underlying cause (35.7+/-11.2 years old) was lower than the age at death with Aids as an associated cause (39.9+/-11.8 years old - p<0.001).

Conclusions: Multiple causes of death allow to track part of the Aids natural history and provide additional data to develop adequate and specific preventive actions.
