Differences in the relation of binge drinking and prescription drug misuse to suicide ideation and attempts between college-aged adults and adults above the age of 25: Findings from the 2015–2019 National Survey on Drug Use and Health (NSDUH)

Objective To clarify the role of age in risk associated with drug misuse and binge drinking, this study examines the differential relations of binge drinking and prescription drug misuse to risk of suicidal ideation and attempts in young adults of college age (18–24) compared to those above the age of 25. Methods We used data from the National Survey on Drug Use and Health (NSDUH) for the years 2015 through 2019 (N = 269,078). Results The study found that, for adults above college age, the presence of any past-month binge drinking was associated with a higher likelihood of past-year suicide ideation (b = 0.427, OR = 1.532, 95%CI [1.388, 1.692]) and attempts (b = 0.637, OR = 1.891, 95%CI [1.271, 2.813]) compared to college-aged adults. Similarly, past-month prescription drug misuse showed stronger associations with past-year suicide ideation (b = 0.831, OR = 2.297, 95%CI [1.952, 2.701]) and attempts (b = 0.539, OR = 1.715, 95%CI [1.264, 2.327]) in adults above college age. Conclusion These findings highlight that binge drinking and prescription drug misuse appears to become more strongly associated with suicide ideation and attempts after adults age beyond young adulthood.
