About a quarter of high school seniors have taken prescription opioids, medically or nonmedically, but exposures have declined over the past 2 years, according to a study.
“The recent declines in medical use of prescription opioids and nonmedical use of prescribed opioids from 2013 through 2015 found in the current study coincide with similar recent declines in U.S. opioid analgesic prescribing,” reported Sean Esteban McCabe, PhD, of the University of Michigan, Ann Arbor, and his associates (Pediatrics 2017 March 20. doi: 10.1542/peds.2016-2387). “Among adolescents who report both medical use of prescription opioids and nonmedical use of prescribed opioids, medical use before initiating nonmedical use of prescribed opioids tended to be most prevalent, and this pattern may be driven by the one-third of adolescents who report nonmedical use of prescribed opioids involving leftover opioid medications from their own previous prescriptions.”
The researchers analyzed data from the Monitoring the Future study from 1976 through 2015, an annual cross-sectional survey of high school seniors from 135 public and private high schools in the United States. Cohorts were nationally representative and varied in size from 2,181 to 3,791 students.
Students were asked whether they had ever been prescribed opioids by a doctor and how often they had ever taken opioids nonmedically. The list of opioids included all the ones available that year, including Vicodin, OxyContin, Percodan, Percocet, Demerol, Ultram, methadone, morphine, opium, and codeine.
Use of opioids for any reason ranged from 16.5% to 24% over the 4 decades, with medical use ranging from a low of 8.5% in 2000 to a peak of 14.4% in 1989. Though 16% of teens had used medical opioids in 1976, prevalence rose to 20% in 1989, then dropped to 13% in 1997 and remained stable. Rates sharply increased to 20% in 2002 – the year Vicodin, OxyContin, and Percocet were included in the questions – and then began declining again in 2013.
Nonmedical use correlated with medical use though remained less prevalent throughout the study period. This correlation was stronger for males, who are more likely to use opioids recreationally, than for females, who are more likely to use them to self-treat pain, the authors wrote.
Both medical and nonmedical use were more prevalent among white students than black students, in line with previous research showing “health disparities for receiving prescription opioids among racial minority patients,” the authors wrote.
Black teens are more often motivated to use opioids for pain relief, suggesting that their lower exposure rates “could result from a lack of adequate treatment, insufficient availability, overprescribing among white populations or underprescribing among nonwhite populations,” they wrote.
One limitation of the study was that absent students or those who had dropped out have a higher risk of opioid use, thereby possibly contributing to underreporting.
