Willingness to HPV self-sampling for cervical cancer screening and its predictors among women attending outpatient clinics in Meru District, Arusha Region, Northern Tanzania

BACKGROUND: The ability for women to self-collect human papillomavirus (HPV) samples can potentially reduce the risk of cervical cancer and increase screening coverage. OBJECTIVES: To assess the willingness to HPV self-sampling for cervical cancer screening and its predictors among women attending outpatient clinics in Arusha region, northern Tanzania. METHODS: A hospital-based cross-sectional study was conducted among 706 women aged 18–55 years in Meru District Hospital and Usa River Health Centre from March to April 2019. Face-to-face intervies were conducted using a questionnaire. Data analysis was performed using Stata version 14.0. The log-binomial regression was used to determine factors associated with willingness to self-collection of HPV samples. RESULTS: Majority (70%) of the women were willing to self-collection of HPV samples for cervical cancer screening and was associated with attending Meru District hospital (PR=2.02, 95%CI 1.77–2.31); good knowledge about cervical cancer warning signs (PR=1.11, 95%CI 1.01–1.22), prevention (PR=1.13, 95%CI 1.04–1.20), and symptoms (PR=1.61, 95%CI 1.33–1.93); and having formal employment (PR=1.22, 95%CI 1.07–1.37). CONCLUSION: The majority of women were willing to self-collect HPV samples for cervical cancer screening. Self-collection is, therefore, an acceptable and viable means of screening for cervical cancer, which has great implications for Tanzania from a health policy perspective.
