Prescription Drug Misuse and Associated Risk Behaviors among Public High School Students in Oklahoma: Data from the 2013 Oklahoma Youth Risk Behavior Survey.

PURPOSE The purpose of this study was to assess the magnitude of prescription drug misuse among Oklahoma high school students, examine associated risk factors, and inform state-based prevention strategies. METHODS Data from the 2013 Oklahoma Youth Risk Behavior Survey were used for this analysis and were representative of public school students in grades 9 through 12 in Oklahoma. Variables were examined using percentages and 95% confidence intervals. The chi-square test was used to test for differences in proportions. Logistic regression was used to produce adjusted odds ratios as measures of association between selected independent variables and prescription drug misuse. RESULTS Nearly one in five students had ever used a prescription drug without a doctor's prescription. While there was no statistically significant difference of prescription drug misuse by gender or grade in the bivariate analysis, after covariate adjustment, females were 1.5 times more likely than males to have misused prescription drugs and twelfth graders were 1.7 times more likely than ninth graders to have misused prescription drugs. CONCLUSION Students who had ever taken prescription drugs without a doctor's prescription were significantly more likely than students who had never taken prescription drugs without a doctor's prescription to have engaged in current tobacco use, current binge drinking, current marijuana use, and lifetime drug use and have a higher prevalence of suicide risk.
