Abstract 2254: A population-based study exploring health care self-efficacy and fertility preservation, family planning, and reproductive concerns among diverse adolescent and young adult cancer survivors

Abstract Purpose: To examine the relationship between health care self-efficacy (HCSE) and fertility experiences among diverse adolescent and young adult (AYA) cancer survivors. Methods: Project Milestones is an ongoing cancer-registry derived cohort survey study recruiting AYAs through the SEER-affiliated Los Angeles Cancer Surveillance Program. Respondents were diagnosed with cancers prototypical for AYAs between 21-39 years and had a 5-year survival probability of ≥50% at diagnosis. Results: Overall, 1442 AYAs responded of which 57. 9% reported the highest possible HCSE (totally confident; score of 3; lower scores reflect greater HCSE), while 42. 1% were somewhat or not at all confident in some areas (score of 4-9; Table 1). Compared to AYAs with lower HCSE, AYAs with the highest HCSE were more likely to report preserving fertility (13. 8% vs. 10. 3%, p. 05) and were less likely to report highly negative change (11. 9% vs. 15. 5%, p. 01) and more likely to report highly positive change (16. 3% vs. 9. 4%, p. 01) to family planning due to cancer. On average, AYAs with the highest HCSE had lower reproductive concerns (range 5-25, lower scores reflect lower concern; 13. 3 vs. 14. 2, p. 01) and were less likely to report worry about: passing on a genetic cancer risk to their child (49. 6% vs. 56. 6%; p. 01), telling their partner they may be unable to have children (13. 8% vs. 21. 5%, p. 01), their ability to become a biological parent (22. 7% vs. 28. 0%, p. 01), and caution having children because they may not be around to raise them (18. 5% vs. 24. 1%, p. 01) than AYAs with lower HCSE. Discussion: Greater HCSE was associated with higher rates of preservation, lower impacts to family planning, and lower reproductive concerns in this population-based study. As one quarter of AYAs have suboptimal HCSE, accessible avenues for obtaining fertility care are needed to temper possible impacts of low HCSE on preserving fertility.
