Abstract
PURPOSE
The objective of this study was to investigate the prevalence of the following risk behaviors: cigarette, electronic cigarette, alcohol, substance and sexual experimentation and delinquent behavior at age 15, stratified by sex and socioeconomic position. We also investigated the prevalence of cigarette and alcohol experimentation at age 11 and the persistence and cumulative incidence of these behaviors between 11 to 15 age.
METHODS
Cohort study. We included 3,491 11-year-old and 1,949 15-year-old adolescents from the 2004 Pelotas Birth Cohort. All outcomes were identified via confidential questionnaires and were analyzed as binary variables.
RESULTS
At age 11, we found a male preponderance of cigarette experimentation. At age 15, alcohol experimentation, cigarette experimentation and substance experimentation had a female preponderance; and cigarette experimentation and sexual experimentation were more prevalent in individuals belonging to low socioeconomic position. We found high rates of cumulative incidence of 'alcohol experimentation' in male and in female adolescents; and high rates of persistence of alcohol experimentation both in male and female.
CONCLUSIONS
Further research should clarify causal paths of high prevalence of risk behaviors during adolescence and its increase in female adolescents.
