Abstract

Objective: The aim of this study is to identify risk behavior profiles associated with alcohol consumption among patrons during or just after departure from nightclubs in Sao Paulo, Brazil. Study design: Cross-sectional survey. Methods: The study used a two-stage cluster sampling survey design. Data were collected on a probabilistic sample of nightclub patrons. Overall, 2422 patrons were interviewed at the entrance of 31 nightclubs. Latent class analysis (LCA) was used to identify risk behavior profiles with an emphasis on risky driving, fights, alcoholic blackouts, and harm and unsafe sex. Results: A 3-class LCA model was selected, with classes consisting of low (43%), medium (33%), and high (24%) risk patrons. Compared to patrons in the low-risk class, patrons in the medium-and high-risk classes were more likely to be men (odds ratio {[}OR] = 2.2, 95% confidence interval [CI] {[}1.2-4.0] and OR = 3.2, 95% CI {[}1.8-5.8], respectively), to have engaged in binge drinking during the last year (OR = 15.0, 95% CI {[}7.2-31.3] and OR = 14.3, 95% CI {[}9.4-21.8]), to be in the highest socioeconomic stratum (OR = 2.6, 95% CI {[}1.3-5.1] and OR = 2.0, 95% CI {[}1.2-3.5]) and to have been interviewed at a hip-hop music nightclub (OR = 2.8, 95% CI {[}1.1-6.8] and OR = 3.7, 95% CI {[}1.5-9.1]). Conclusions: Risk behaviors were not equally distributed among nightclubs. Individual-and environmental-level characteristics are associated with higher risk. Alcohol harm reduction, such as the implementation of a responsible drinking service, should be implemented in Sao Paulo nightclubs. (C) 2017 The Royal Society for Public Health.
