BackgroundIn this study, we aimed to evaluate the knowledge and awareness about cervical cancer, human papillomavirus (HPV) and its vaccine among women living in the western region of Saudi Arabia.MethodologyUsing a cross-sectional online survey, this study assesses the knowledge and awareness level of HPV and the risk factors of cervical cancer among women living in the western region of Saudi Arabia. The design of the questionnaire is based on several earlier studies in different populations.ResultsThe total completed responses include a sample of 624 that was subjected to statistical analysis; the analysis showed that only 34.6% were aware of HPV. Participants who belonged to the 21-30 and 31-40-year-old groups had comparatively more awareness than other age groups (p<0.001). Most (83.8%) believed that it would cause cervical cancer. Less than half (45.8%) knew that there is a vaccine against HPV infection. When we assessed the willingness to receive the vaccine, it was found that 75.8% were willing to take it.ConclusionsThe study found that women in the western region of Saudi Arabia have limited knowledge of cervical cancer and HPV and its vaccine. There is a need to educate and promote awareness of HPV and its complications for women in the western region of Saudi Arabia.
