Tuberculosis mortality in Brazilian capitals, 2008-2010.

OBJECTIVE

to analyze the association between tuberculosis mortality and socio-demographics and health indicators in the capitals of Brazilian states and the Federal District.

METHODS

this is an ecological study whose outcome was the standardized coefficient of tuberculosis mortality in the 2008-2010 period; the independent variables comprised 16 indicators, grouped into three blocks; Pearson correlation test and multiple linear regression were applied for analysis.

RESULTS

4,744 deaths from tuberculosis were registered in the 27 municipalities (2.7 deaths per 100,000 inhabitants); the following indicators were associated with tuberculosis mortality (p<0.10): income inequality (Gini index of monthly income of individuals over 10 years old: β=0.454; 95%CI 6.21;28.51), proportion of migrants in the municipality (β=0.537 95%CI 0.12;0.31), poor black-skinned individuals (β=0.302 95%CI 0.004;0.109) and coefficient of Tb/HIV coinfection (β=0.449 95%CI 0.05;0.28).

CONCLUSION

tuberculosis mortality was higher in capitals with greater income inequality, migration, poverty among black-skinned individuals and occurrence of Tb/HIV coinfection.
