National trends in the prevalence of suicidal ideation and behavior among young adults and receipt of mental health care among suicidal young adults

Objective This study examined national trends in the prevalence of suicidal ideation and behavior among young adults and receipt of mental health care among suicidal young adults. Method We examined restricted data from 145,800 persons aged 18 to 25 years who participated in the 2009 to 2015 National Surveys on Drug Use and Health. Descriptive analyses and bivariable and multivariable logistic regressions were applied. Results Among US young adults during 2009 to 2015, the 12-month prevalence of suicidal ideation increased from 6.1% to 8.3%, the 12-month prevalence of suicide plan increased from 2.0% to 2.7%, and 12-month prevalence of suicide attempt increased from 1.1% to 1.6%. After adjusting for personal factors and changes in residing county’s population characteristics, we found upward trends in suicidal ideation among non-Hispanic whites and Hispanics, an upward trend in suicide plan among young adults overall, and an upward trend in suicide attempt among those without major depressive episodes (MDE). Among young adults with MDE, the prevalence of suicide attempt remained high and unchanged. During 2009 to 2015, trends in receipt of mental health care remained unchanged among most suicidal young adults and declined slightly among uninsured suicidal young adults. The annual average prevalence of receipt of mental health care was 36.2% among suicidal young adults. Conclusion During 2009 to 2015, suicidal ideation, suicide plan, and suicide attempt increased among young adults overall, but receipt of mental health care among suicidal young adults did not increase. Our results suggest that effective efforts are needed for suicide prevention and promotion of mental health care among young adults.
