Purpose Adolescent and young adults (AYAs) oncology populations have unique sexual health concerns that deserve more attention. The current study aimed to describe the prevalence and characteristics of sexual health and related concerns in AYAs in active treatment and survivorship to move toward integrating sexual health in routine care. Methods A total of 127 AYAs (ages 19-39) in active treatment and survivorship were recruited from three outpatient oncology clinics. In addition to providing demographic and clinical information, they completed an adapted version of the NCCN Distress Thermometer and Problem List (AYA-POST; AYA-SPOST) as part of an ongoing needs assessment study. Results Over one quarter (27.6%) of the total sample ( M age = 31.96, SD = 5.33) - 31.9% of active treatment, and 21.8% in survivorship - reported at least one sexual health concern (i.e., sexual concern, loss of libido, pain with sex, and unprotected sex). The most frequently endorsed concerns differed between active treatments and survivorship. Both genders often endorsed general sexual concerns and loss of libido. Conclusion The literature on sexual concerns in the AYA population is sparse and inconclusive, especially accounting for gender and other types of concerns. The current study highlights the need for further examination between treatment status, psychosexual concerns, emotional distress, and demographic and clinical factors. Given the prevalence of sexual concerns in AYAs in active treatment and survivorship, providers should consider integrating assessment and discussion of these needs at onset of diagnosis and as part of monitoring.
