Purpose: Despite health implications, sexual activity and substance use among adolescents and young adults (AYAs) receiving cancer treatment are understudied. Methods: AYAs 12-25 years of age participated in a randomized controlled trial testing the efficacy of a resilience intervention. They were fluent in English and either diagnosed with new cancer (NC) or advanced cancer (AC). At baseline and 6 months, participants self-reported sexual activity and substance use. We describe the percentage of AYAs who endorsed each behavior and a count of total behaviors endorsed by each respondent. We describe frequencies by sex/gender (male/female), age (<18/≥18), and disease status (AC/NC). Results: Participants (N = 92) were majority white/Caucasian (57%), 12-17 years old (73%), and diagnosed with leukemia/lymphoma (62%); 32% had AC. Responses were not associated with the intervention; hence, we summarized data from the whole cohort. At both time points, median behavior endorsed was 2. At baseline and follow-up, 87% and 81% endorsed at least 1 behavior: 13% and 15% were sexually active, 75% and 73% of whom used birth control inconsistently; and 22% and 22% reported drinking alcohol, 31% and 27% using prescription opioids/sedatives, 19% and 22% using other drugs, and 9% and 7% using tobacco. Young adults engaged in most behaviors more frequently than adolescents (e.g., 48% vs. 12% alcohol at baseline); males engaged in sexual activity more frequently than females (e.g., 20% vs. 5% sexually active at baseline); and AYAs with NC engaged in most behaviors more frequently than those with AC (18% vs. 0% sexually active at baseline). Conclusion: AYAs engage in sexual activity and substance use during cancer treatment.
