RESUMO
PURPOSE: Misuse of prescription medication has increased during the last 20 years among adolescents and young adults. We aimed to report the prevalence and factors associated with misuse of tranquilizers, sedatives, and sleeping pills (TSSp) in high-school students in Spain. We also analyzed misuse of these drugs during the decade 2004-2014. METHODS: Nationwide, epidemiological, cross-sectional study on the misuse of TSSp by the Spanish school population. We used individualized secondary data retrieved from the 2004 and 2014 Spanish State Survey on Drug Use in Secondary Education. A total of 179,114 surveys respondents aged 14-18 years. Estimates and trends of previous 30 days misuse of TSSp. RESULTS: The prevalence of TSSp misuse among school population aged 14-18-years increased significantly from 2004 (2.40%) to 2014 (2.96%). The values for consumption were always greater in adolescent girls than boys throughout the study (3.51% vs. 2.18%). The variables associated with a greater probability of TSSp misuse were consumption of alcohol, tobacco, and marijuana. Students who reported consumption of an illicit drug other than marijuana during the previous year are 4.91 times more likely to misuse TSSp (adjusted odds ratioâ¯=â¯4.91; 95% confidence interval, 4.15-5.81). CONCLUSIONS: We found that misuse of TSSp by adolescents in Spain has significantly increased from 2004 to 2014. Misuse of TSSp was more likely in adolescent girls than Spanish boys. Alcohol, tobacco, and marijuana consumption are factors associated with the use of TSSp.
