Heavy episodic drinking trends in the Brazilian state capitals and Federal District, 2006-2018: An ecological time series analysis

Abstract

Objective: To assess heavy episodic drinking trends in the 26 Brazilian state capitals and Federal District, overall and according to sex. Methods: This was an ecological time series study of heavy episodic drinking patterns among adults, from 2006 to 2018. The data were obtained from VIGITEL Survey time series. Prais-Winsten regression was used. Results: In the period studied a stationary heavy episodic drinking trend was found in 23 out of the 27 state capitals, with the exception of Macapá, where there was a decrease in this practice, and in São Paulo, Florianópolis and the Federal District, where an increase was found. There were important differences by sex in relation to heavy episodic drinking, with a tendency to increased consumption among women in seven state capitals. Conclusion: There was no reduction in heavy episodic drinking in most capitals, showing the urgency of implementing interventions to reduce alcohol consumption among the Brazilian population.
