Gender differences in trends for heroin use and nonmedical prescription opioid use, 2007-2014

Trends in the current opioid epidemic in the United States show that use of heroin is increasing while nonmedical use of prescription opioids is slowing. Understanding gender differences in these trends is essential to efforts to address the opioid epidemic. This study compared gender difference in trends in heroin and nonmedical prescription opioid use in the U.S. between 2007 and 2014.

Data from the National Survey on Drug Use and Health (NSDUH) were used to trace prevalence and to estimate risk for heroin and nonmedical prescription opioid use in the last year for women and men.

Prevalence rates in the total sample (N = 447,188) indicate a notable increase in heroin use and a steady decline in the nonmedical use of prescription opioids between 2007 and 2014 for both women and men. Women are increasing heroin use at a faster rate than men but decreasing nonmedical prescription opioid use at a slower rate than men. Overall, risk factors for both heroin use and nonmedical prescription opioid use are similar to other illicit substances, but the magnitude of associations indicates that women may be at greater risk for the nonmedical use of prescription opioids than for the use of heroin.

Trend analyses reveal a linear increase in heroin use and a quadratic decline in nonmedical prescription opioid use at the population level. The differential rates of change between men and women in use of both opioids highlight the need for comprehensive, gender-sensitive approaches to prevention and treatment for both heroin and nonmedical prescription opioid use. Future research should continue to explore gender differences in treatment access, including access to medication-assisted treatments and treatments integrated with health and social services, especially for women.
