Results: Mortality showed a stationary trend for Brazil as a whole (APC = 0.6; 95%CI-4.2;3.0), a falling trend in individuals aged 20-29 years in the South (APC =-7.4; 95%CI-10.0;-4.3) and Northeast (APC =-3.4; 95%CI-6.4;-0.4) regions, in people aged 30-39 in the Midwest region (APC =-3,8; 95%CI-7.4;-0.1) and 40-49 in the South (APC =-2.1; 95%CI-3.8;-0.4), North (APC =-3.1; 95%CI-5.7;-0.5) and Midwest (APC =-2.9; 95%CI-5.5;-0.3) regions. Conclusion: Mortality f rom mental and behavioral disorders due to alcohol use showed a stationary trend nationally and a falling trend in some age groups regionally.
