Objective: To estimate the association of parental drunkenness and parenting style with alcohol consumption among adolescents and the contributions of parental drunkenness and parenting style to the prevalence of binge drinking among adolescents.
Method: Cross-sectional survey of a representative sample of secondary students aged 13 to 18 from 27 Brazilian state capitals (n=17,028). Private and public schools were included. A self-report questionnaire collected data on adolescents' alcohol drinking behavior, parenting styles, and parenting and peer models of drunkenness.
Results: Non-authoritative parenting style and parental drunkenness are associated with binge drinking among adolescents. Authoritarian, indulgent, and negligent parenting styles were associated with 1.50-, 2.51-, and 2.82-fold increases in prevalence of adolescent binge drinking, and parental drunkenness, with a 1.99-fold increase. The non-authoritative parenting style made a larger contribution than parental drunkenness to adolescent binge drinking.
Conclusions: Non-authoritative parenting style and parental drunkenness seem to play an important role in adolescents' binge drinking behavior. At the population level, parenting style appears associated with a greater contribution to this behavior among adolescents. Prevention strategies targeting parental drunkenness may be bolstered if a broader approach including parenting styles is in place.
