This scope of this paper was to conduct an ecological analysis of suicide mortality of people aged 60 years or more in Brazilian municipalities between 2005 and 2007, by investigating factors associated with the event. Data on suicide deaths were extracted from the Mortality Information System, codes X60 to X86 and Y87.0 (ICD-10). Poisson, negative binomial and zero-inflated negative binomial (ZINB) regression models were adjusted. The latter exhibited the best results when comparing models. The proportion of non-whites (negative association), the rate of hospitalization for mood disorders (positive association) and sex ratio (negative association) were identified as factors associated with suicide.
