Knowledge, perceptions and uptake of human papilloma virus vaccine among adolescent girls in Kampala, Uganda; a mixed-methods school-based study

Abstract

Abstract Background Cervical cancer is a major public health challenge, accounting for substantial morbidity and mortality. Human Papilloma Virus (HPV) vaccination is the recommended primary public health intervention for HPV infection prevention. However, there’s limited evidence on the level of knowledge, attitude, and practices of adolescent girls regarding HPV vaccination in Kampala city, Uganda. This study assessed the knowledge, perceptions, and practices of adolescent girls aged 10-14 years towards HPV vaccination program in Kampala, Uganda to generate evidence to guide programs targeted at improving uptake of the vaccine. Methods A convergent parallel mixed methods study was conducted in Kampala, Uganda. A structured questionnaire was used to elicit data from 524 adolescent girls. In addition, 6 Focus group discussions, and 24 key informant interviews (teacher and parents) were conducted. Multistage and purposive sampling techniques were used to select quantitative and qualitative participants respectively. Quantitative data were entered using epidata, cleaned and analyzed using Stata v14 while qualitative data were analyzed using thematic content analysis in atlas ti version 8. Results Overall, only 8.6% (45/524) of the girls had completed the HPV vaccine schedule of two dozes, 49.2% (258/524) of the girls had low knowledge about the HPV vaccine and teachers and parents affirmed this lack of knowledge among adolescent girls especially concerning the target age group, dosage, and vaccine interval. About 51.9% (272/524) of girls had negative perceptions towards HPV vaccination. Parents expressed negative perceptions, beliefs, superstitions, and safety concerns of the vaccine.Girls residing in rural areas (adjusted prevalence ratio, aPR = 0.35, C. I = 0.14–0.85) had lower knowledge levels compared to those in urban areas. Girls whose mothers were healthcare providers (aPR = 1.94, C. I = 1.10–3.41), girls with high knowledge levels (aPR = 1.79, C. I = 1.21–2.63) and positive perceptions (aPR = 2.87, C. I = 1.93–4.27) had a higher prevalence of being fully vaccinated. Conclusion Girls generally had low levels of knowledge, negative perceptions, and poor uptake of HPV vaccination. We recommend sensitization campaigns in schools and communities to improve awareness, perceptions, and practices of stakeholders towards HPV vaccination.
