Factors associated with human papillomavirus vaccination among young adult women in the United States

Abstract

Background: Human papillomavirus (HPV) vaccination is recommended to protect against HPV-related diseases.

Objective: To estimate HPV vaccine coverage and assess factors associated with vaccine awareness, initiation and receipt of 3 doses among women age 18-30 years.

Methods: Data from the 2010 National Health Interview Survey were analyzed to assess associations of HPV vaccination among women age 18-26 (n=1866) and 27-30 years (n=1028) with previous HPV exposure, cervical cancer screening and selected demographic, health care and behavioral characteristics using bivariate analysis and multivariable logistic regression.

Results: Overall, 23.2% of women age 18-26 and 6.7% of women age 27-30 years reported receiving at least 1 dose of HPV vaccine. In multivariable analyses among women age 18-26 years, not being married, having a regular physician, seeing a physician or obstetrician/gynecologist in the past year, influenza vaccination in the past year, and receipt of other recommended vaccines were associated with HPV vaccination. One-third of unvaccinated women age 18-26 years (n=490) were interested in receiving HPV vaccine. Among women who were not interested in receiving HPV vaccine (n=920), the main reasons reported included: not needing the vaccine (41.3%); concerns about safety of the vaccine (12.5%); not knowing enough about the vaccine (11.9%); not being sexually active (8.2%); a doctor not recommending the vaccine (7.6%); and already having HPV (2.7%). Among women with health insurance, 10 or more physician contacts within the past year and no contraindications, 74.5% reported not receiving HPV vaccine.

Conclusions: HPV vaccination coverage among women age 18-26 years remains low. Opportunities to vaccinate are missed. Healthcare providers can play an important role in educating young women about HPV and encouraging vaccination. Successful public health and educational interventions will need to address physician attitudes and practice patterns and other factors that influence vaccination behaviors.
