Abstract
BACKGROUND: US guidelines recommend human papillomavirus (HPV) vaccination for males and females up to 26, with more recent extended coverage for those 27-45 years based on discussion with patients' clinician. This study seeks to assess trends and disparities of vaccination in the United States based on demographic characteristics. METHODS: Data was obtained from the National Health and Nutrition Examination Survey between 2007 and 2016. Chi-squared analyses were utilized for statistical methods. RESULTS: Of 12,844 participants (median age: 22; range: 9-36 years), 2,711 (21.3%) initiated HPV vaccination; of which 1,358 (56.3%) completed the 3-dose vaccination series. Vaccination rates were higher in females compared to males (24.6% vs. 13.0%; p<0.001) and in Whites compared to Mexican Americans (22.6% vs. 19.4%; p=0.02). The uninsured had lower vaccination rates than private insurance and Medicaid (12.5% vs. 22.4% vs. 28.5%; p<0.001). We divided the 10 year study into five separate time periods (2007-2008, 2009-2010, 2011-2012, 2013-2014, and 2015-2016) to analyze trends. Vaccine initiation increased from 19.6% to 49.6% for 14-19-year olds (p<0.001), 10.4% to 35.5% for females (p<0.001), and 8.5% to 32.9% for Blacks (p<0.001). Although on trend analyses, the vaccination rates with the highest proportional increase were found in those: over 25-29 year olds (4.56 fold), Mexican Americans (4.56 fold), below high school education (2.32 fold), and low income group (2.90 fold) over time. CONCLUSIONS: HPV vaccination rates in Mexican Americans increased nearly 5-fold over the last 10 years. However, their vaccination rates continue to lag behind Whites and Blacks.
