Abstract
OBJECTIVES
Adolescents and young adults (AYAs) with chronic illnesses use substances at similar, if not greater, rates compared to healthy peers. The present study aimed to examine rates and patterns of tobacco use, marijuana use, and binge drinking in AYAs with inflammatory bowel diseases. We expected that substance use would be associated with poorer physical health, psychosocial functioning, and disease management.
METHODS
One hundred thirty-two AYAs completed a single set of surveys assessing demographics, disease activity, healthcare utilization, health-related quality of life (HRQoL), inflammatory bowel disease-specific self-efficacy, adherence barriers, disease management skills, and substance use in the last 30 days (eg, tobacco use, marijuana use, binge drinking). Exploratory cluster analyses, followed by chi-square tests and analyses of variance examined patterns of substance use and correlates of cluster membership.
RESULTS
Four patterns emerged from the sample: Global Users (n = 17), Marijuana Users Engaging in Binge Drinking (n = 18), Exclusive Binge Drinkers (n = 21), and Global Abstainers (n = 76). Groups differed by age, gender, disease activity, healthcare utilization, HRQoL, self-efficacy, and adherence barriers with medium and large effect sizes (P < .05).
CONCLUSIONS
Older age, male gender, active disease, at least 1 hospitalization in the past year, low self-efficacy, low HRQoL, and high adherence barriers were significantly more likely for those reporting multisubstance use. In addition, all those reporting both marijuana use and binge drinking also reported tobacco use. Future research ought to examine these associations longitudinally and throughout the transition to adult care.
