Abstract:

This study aims at investigating the prevalence of alcohol and tobacco experimentation among adolescents of the center-western region of Brazil and its association with sociodemographic factors. It is a cross-sectional study, with datathe National school-based Health Survey – PeNSE, carried out in 2015. The sample was composed of 9th year graders of Elementary School. The dependent variable was the experimentation of alcohol and tobacco at some point in life. For the identification of the associated variables, the Poisson regression model was performed. The estimated prevalence of alcohol and tobacco experimentation was 57.17% (IC95%: 56.20 to 58.14) and 22.38% (IC95%: 21.56 to 23.20), respectively. The prevalence of alcohol experimentation in the female gender was higher than in the boys, however for tobacco, males presented higher prevalence than females. Alcohol and tobacco experimentation was statistically significant as people grow old. The administrative dependence of public schools revealed prevalence of 23.99% higher than private schools in tobacco experimentation. It was concluded that alcohol and tobacco experimentation was high among school adolescents and was shown to be associated with socio-demographic factors.
