AIDS is the fourth leading cause of death worldwide and, currently, the
overall prevalence rate of HIV infection in Brazil is 0.5% among men and 0.3%
Objective: To evaluate the spatiotemporal trend of AIDS in Brazil from 2006 to
2012 and its relationship with human development index (HDI) and their components
income, education and life expectancy.
Methods: This ecological study evaluate the spatiotemporal trend of standardized
incidence ratio of AIDS among adults in Brazil from 2006 to 2012 and its relationship
with HDI by using a Bayesian analysis, considering the Brazilian Federal
Units as units of analysis. The proposed statistical model allows obtaining a standardized incidence
ratio (SIR, adjusted by gender and age).
Results: Among the men, our results show higher incidence rates in the States of the Southern regions
as well as in the state of Amazonas (Northern Brazil). In females, we found other patterns for SIR,
with higher incidence rates in the states of Rio de Janeiro (Southeast region), Rio Grande do Sul and
Santa Catarina (both in Southern region). Among men it was observed as an expressive association
between the SIR values and the overall HDI and income and education components, but it was observed
to have an inverse association with the life expectancy component. Among women, it is noted
that the SIR values are associated with the overall HDI and the education components only at the beginning
of the studied period.
Discussion: AIDS remains a major public health problem in Brazil, mainly in the southern and southeastern
regions of the country. Considering its association with HDI, it is noted that the disease still
remains related to the pattern observed in the early years of the studied period, at least in the more developed
regions of Brazil. This certainly happened because of the chronicity of the disease, thus affecting
people with good socioeconomic status.
