The Link Between Depressive Symptoms and Vaping Nicotine in U.S. Adolescents, 2017–2019.

While there is a well-established association between depression and cigarette use, the mental health sequelae of vaping nicotine remain unclear. This study examined whether adolescents with depressive symptoms had higher odds of vaping nicotine than others, and how this association differed when examining vaping with cigarette use, vaping without cigarette use, and cigarette use alone. Using 2017–2019 Monitoring the Future data, we examined U.S. adolescents in the eighth, 10th and 12th grades surveyed in schools across the contiguous states. Depressive symptoms were measured by using questions around negative affect and hopelessness. The outcome included vaping with cigarette use; vaping without cigarette use; cigarette use alone; and neither. Control covariates included sex, race, highest level of parental education, and average grades. The sample included 32,636 adolescents. Depressive symptoms were positively associated with comorbid vaping and cigarette use across all grades (eighth graders: adjusted odds ratio [aOR] = 3.52 [95% confidence interval (CI): 1.94–6.39]; 10th graders: aOR = 2.26 [95% CI: 1.51–3.38]; 12th graders: aOR = 1.81 [95% CI: 1.05–3.12]); vaping without cigarette use among eighth graders (eighth graders: aOR = 2.01 [95% CI: 1.46–2.77]; 10th graders: aOR = 1.20 [95% CI:.97–1.49]; 12th graders: aOR = 1.20 [95% CI:.84–1.70]); and cigarette use alone among eighth and 10th graders (eighth graders: aOR = 2.91 [95% CI: 1.50–5.62]; 10th graders: aOR = 2.29 [95% CI: 1.35–3.88]; 12th graders: aOR = 1.73 [95% CI:.83–3.61]). Eighth grade adolescents with depressive symptoms have increased odds of vaping nicotine with and without cigarette use. As vaping prevalence increases, clinician assessment of adolescent vaping should concomitantly acknowledge potential mental health correlates. Vaping may be a marker for a broader constellation of adolescent health concerns, including mental health. [ABSTRACT FROM AUTHOR]
