Tendencias en el consumo de alcohol en los adolescentes escolarizados españoles a lo largo de la primera década del siglo xxi

Abstract

ObjectiveTo determine trends in beer, wine, and liquor consumption among Spanish adolescents in 2002, 2006, and 2010, as well as drunkenness trends during the same period. MethodThe study sample was composed of 23,169 adolescents aged 15 to 18 years old: 7,103 in 2002, 10,443 in 2006 and 5,623 in 2010. In the three time points of the study, the data were representative of Spanish adolescent students. We used the alcohol consumption questionnaire designed by the international team of the Health Behavior in School-aged Children (HBSC) study. We estimated odds ratios and 95% confidence intervals through logistic regressions. ResultsThe main results showed a decrease in frequent consumption of wine and liquor from 2002 to 2010. This decrease was maintained after controlling for the variability due to the participants’ gender and age. However, an increasing trend was found in drunkenness episodes in the different cohorts of the adolescents under study. ConclusionsThe results of this study are of particular importance in the analysis of the effects of the public health policies implemented during this time period. We also found changes in consumption patterns of the various alcoholic drinks, which may constitute key information in the design of new public health policies.
