Abstract
Abstract Background: Over 90% of Human papillomavirus (HPV)-associated cancers could be prevented with the HPV vaccination; yet vaccine uptake remains suboptimal. Awareness that HPV causes several cancers has been shown to improve HPV vaccination uptake. While several efforts to increase HPV-associated diseases awareness as a way to improve vaccine uptake have been made, it is unclear if these efforts have resulted in increased HPV-associated cancers awareness over the years. We examined the awareness of the link between HPV and HPV-associated cancers between 2014 and 2020 in the US. Methods: We used the Health Information National Trends Survey (HINTS) data from 2014 (HINTS 4 cycle 4) to 2020 (HINTS 5 cycle 4). HINTS is a nationally representative survey of adults aged ≥18 in the civilian non-institutionalized US population. HPV-associated cancer awareness was assessed with the question “Do you think HPV can cause i) anal ii) cervical iii) oral and iv) penile cancers”. Responses were “yes”, “no” and “not sure”. Weighted prevalence estimates and corresponding 95% CIs were calculated for all four HPV-associated cancer awareness questions at each timepoint. Results: There were five timepoints included in the study: HINTS 4 cycle 4 (2014, n=2239), HINTS 5 cycle 1 (2017, n=2034), HINTS 5 cycle 2 (2018, n=2050), HINTS 5 cycle 3 (2019, n=2270), and HINTS 5 cycle 4 (2020, n=2340). Awareness of the link between HPV and cervical cancer was high (77.6% in 2014) but decreased by 7.4% between 2014 and 2020 (Table). However, awareness of the link between HPV and anal, oral, and penile cancers was low (around 30% for each cancer type) and remained stable between 2014 and 2020 (Table). Conclusions: Awareness of the link between HPV and HPV-associated cancers has remained steady for anal, oral and penile cancers or declined slightly for cervical cancer over time. There is a need for implementing novel and target interventions to increase awareness and counteract HPV vaccine disinformation.
