RESUMEN
INTRODUCTION: College students are a priority population for substance use prevention, and other studies have reported associations between mental health and e-cigarette use. This study described the association of mental health to e-cigarette and other substance use (ECIG+ use) among US college students. METHODS: We used Fall 2018 and Spring 2019 National College Health Assessment data among undergraduate students aged 18-24 years (n=55654) at 138 institutions. We characterized substance use patterns and used multinomial regression to model adjusted odds of past 30-day ECIG use type [no substance use (reference); sole e-cigarette use; e-cigarette use and other substance use (ECIG+ use); no e-cigarette use but other substance use] by mental health characteristics, past 12-month diagnosis/treatment and psychological distress, individual characteristics, and college characteristics. RESULTS: Alcohol was the most prevalent substance (58%) used, followed by cannabis (23%) and e-cigarettes (15%). Nearly all (95%) students who used e-cigarettes reported using another substance. Adjusted odds of ECIG+ use (vs no substance use) were higher among students with past 12-month mental health diagnosis/treatment (AOR=1.5; 95% CI: 1.4-1.6) and higher psychological distress (AOR=1.1; 95% CI: 1.1-1.2). Other characteristics significantly associated with ECIG+ use included gender identity, sexual orientation, race and ethnicity, self-rated health, year in school, cumulative grade average, fraternity/sorority membership, and current residence. CONCLUSIONS: Most students who used e-cigarettes also reported other substance use, and this pattern of use was associated with poorer mental health outcomes than no substance use. Clarifying the relationship between mental health and ECIG+ use may enhance health interventions for college students.
RESUMEN
OBJECTIVE: We examined the effects of a two-part intervention including an online health risk assessment with personalized feedback and a brief in-person alcohol intervention for high-risk students. PARTICIPANTS: Participants were 1,987 sophomore students, with 259 completing the alcohol intervention and 91 completing all follow-up surveys. METHODS: Students were invited to take an initial online health assessment covering a range of health behaviors and subsequent 3-month follow-up survey. Students who reported high-risk alcohol behaviors on the assessment were invited to participate in two one-on-one sessions utilizing motivational interviewing. Follow-up surveys occurred 3, 6 and 12 months later. RESULTS: Students who completed the health risk assessment reported knowledge and behavior changes. Students who completed the in-person alcohol intervention showed significant reductions in alcohol risk behavior 3-, 6- and 12-months post-intervention. CONCLUSIONS: A two-part intervention for non-mandated students including a health risk assessment and one-on-one intervention shows promise in reducing alcohol risk.
