Objectives To evaluate differences in cervical cancer incidence, screening, and HPV vaccination between Hispanics and Whites in the United States.

Methods Data were obtained from the United States Cancer Statistics (USCS) from 2001 to 2017 and the Behavioral Risk Factor Surveillance System (BRFSS). SEER*Stat and Joinpoint regression program were used for statistical analyses.

Results Based on USCS data, in 2017 the overall incidence of cervical cancer was 7.5/100,000 in Hispanic women compared to 6.2/100,000 in White women. Hispanics aged 35 to 39 years had the highest incidence at 15.9/100,000. We then used BRFSS data to identify potential deficiencies in screening and prevention, and found that 11.6% of all Hispanics were never screened compared to only 5.1% of Whites. When stratified by age, Hispanics 25 to 29 years old had the highest rate of absent screening at 11.2%, compared to 6.4% of Whites of the same age. In examining adherence to screening guidelines, we found that 11.4% of Hispanics and 26.6% of Whites were non-adherent (no screening in the last five or more years). Furthermore, of those eligible for HPV vaccination in 2006, only 37.3% of Hispanics had received the vaccine by 2017, compared to 50.0% of Whites.

Conclusions Cervical cancer incidence is 20% higher in Hispanics compared to Whites in the United States. Poor compliance with cervical cancer screening and lower vaccination rates may explain this disparity.
