Background: HPV vaccination is recommended for female and male adolescents in the U.S. to prevent HPV-related cancer, yet the uptake remains suboptimal nationwide. Asian American female adolescents have the lowest HPV vaccine rates. Successful HPV vaccine depends heavily on parents' attitudes, perceptions, and willingness to have their adolescents vaccinated.

Objective: This study was designed to test the feasibility and outcomes of a provider-based culturally tailored intervention among Asian American parents and their eligible adolescents.

Methods: Asian American parents (n=120) who had adolescent girls and boys aged 11 to 18 (n=170) were recruited from a primary-care community health center. The primary outcome was first and second shots of HPV vaccination uptake 6 months following the intervention. Secondary outcomes included third shot of HPV vaccine at 6 months after the intervention for adolescents over the age of 12, increase in knowledge and belief in HPV vaccine, and engagement of adolescents in decision-making at post intervention.

Results: Among 170 adolescents, 68% of them received first and second shots of HPV vaccine (73% for girls vs 63% for boys). Among 81 adolescents over the age of 12, 63% of them received third shot (63% for girls vs 76% for boys). Parents' (n=120) knowledge and belief in HPV vaccine and engagement of adolescents in decision-making have significantly increased from baseline to post intervention (p<0.001).

Conclusion: A culturally tailored pilot intervention in a clinical setting demonstrated promising effects, which can potentially yield significant increase in HPV vaccine uptake among Asian American and other underserved ethnic minority female and male adolescents to prevent cancer.
