A randomized, controlled trial of a web-based tailored intervention to increase human papillomavirus vaccination among people living with HIV/AIDS.

Abstract

BackgroundHuman papillomavirus (HPV) causes several cancers that disproportionally affect people living with HIV/AIDS (PLWH) yet there is a paucity of research on interventions to foster HPV vaccine use in this population. We sought to evaluate the efficacy of a web-based, tailored intervention (e-HPV) to promote HPV vaccination among PLWH.MethodsThis is a randomized controlled trial with PLWH aged 18 to 45 years. Participants were recruited between January and June 2022 and randomized into two groups: experimental group (e-HPV), which received information about HPV and the HPV vaccine, based on the Protection Motivation Theory and control group, who received a clipping of information from the page maintained by the Ministry of Health dedicated to informing the population about HPV and the HPV vaccine. The primary and secondary outcomes were the percentage of PLWH willing to get HPV vaccine and HPV vaccine initiation (i.e., receipt of any doses by PLWH), respectively.ResultsA total of 654 individuals were randomly allocated: 327 in the e-HPV and 327 in the control group. The average age was 29.7 years, the majority were men (71.4%), black or mixed race (63.2%). The intention to get vaccinated against HPV was approximately twice as high among participants in the e-HPV vs. control group (OR = 2.0, 95% CI: 1.3-3.4; p ConclusionsThe intervention was acceptable and efficacious in increasing HPV vaccination among PLWH. Future studies are warranted to optimize and disseminate the e-HPV intervention to settings providing services to PLWH.Trial registrationBrazilian Clinical Trials Registry RBR-557mbvy.
