Abstract

Objective:

to analyze prevalence and factors associated with lifetime drug use in adolescents.

Methods:

this was a cross-sectional study carried out in 2015 with elementary and high school students in Cuiabá, MT, Brazil, aged 10-19; drug use (except alcohol and tobacco) was analyzed according to sociodemographic, school and family variables; data were submitted to descriptive analysis and Poisson regression to estimate prevalence ratios (PR) and 95% confidence intervals (95%CI).

Results:

drug use prevalence was 23.5% (95%CI 20.8;26.4) and was associated with unsatisfactory family relationships (PR=1.43; 95%CI 1.08;1.91) and non-authoritative parenting style (PR=1.67; 95%CI 1.14;2.44).

Conclusion:

prevalence of drug use among adolescents was associated with unsatisfactory family relationships, especially when conflicts were between parents and when parenting style was non-authoritative.
