Flavored Ready-to-Drink Alcohol Restriction in Young Adults: Behavioral and Biomarker Outcomes
Sponsor: Medical University of South Carolina
Summary
This pilot randomized behavioral study evaluates the feasibility, adherence, and acceptability of an intervention to restrict flavored ready-to-drink (RTD) alcoholic beverages among young adults who regularly use both alcohol and e-cigarettes. Participants will complete a 2-week baseline period followed by a 2-week intervention period. Participants will be randomized to either avoid flavored RTD alcoholic beverages or continue their usual alcohol consumption. Primary outcomes include feasibility, adherence, acceptability. Secondary outcomes include preliminary efficacy of flavored RTD restriction on alcohol consumption and e-cigarette use measured through daily electronic diaries; biomarkers of alcohol and nicotine exposure, including urinary ethyl glucuronide (EtG), urinary cotinine, and blood phosphatidylethanol (PEth).
