Vaginal self-sampling for HPV in the context of cervical cancer screening

Abstract Background Effective cervical cancer screening programme has the potential to improve disease outcomes, yet women’s participation rates in Latvia remain suboptimal. Utilizing vaginal self-sampling for HPV, a convenient method, has demonstrated efficacy in boosting participation in under-screened populations. We analysed sociodemographic factors, as well as health behaviours with the preference for vaginal self-sampling procedures for early detection of cervical cancer. Methods Cross-sectional survey (2021-2022) included 1313 women in Latvia. Sampling was done in the colposcopy clinic and among GP practices. In the univariate analysis cervical cancer examination preference (self-test or by a physician) was analysed in association sociodemographic factors, participation in the screening, HPV status, study group, and health-related behaviour. Financed by “Internal consolidation of RSU and external consolidation of RSU with LSPA” (No. 5.2.1.1.i.0/2/24/I/CFLA/005), The EU Recovery and Resilience plan and the state budget, Grant Nr. RSU-PAG-2024/1-0016. Results 48.6 % (n = 538) of the women would prefer to use a vaginal self-test. Higher odds of the vaginal self-test preference were observed among Latvian (OR = 1.4 (1.1-1.8) vs other nationality women, but no other sociodemographic factors showed statistically significant associations. Women in the colposcopy study group (vs GP practices) were more likely to utilize self-sampling (OR = 1.8 (1.4-2.5). Non-participation in cervical cancer screening was related to 2.4 (1.6-3.6) higher odds of self-test preference, but knowledge about screening was related to 1.5 (1.1-2.0) times higher odds. Women who were HPV-negative were more likely to prefer vaginal self-test for HPV (OR = 1.4 (1.1-1.8) in comparison to HPV-positive women. Health-related behaviour did not show any associations. Conclusions Vaginal self-test for HPV can be effectively used to reach under-screened populations and enhance cervical cancer screening coverage. Key messages • The implementation of vaginal self-sampling for HPV testing has the potential to improve participation rates in cervical cancer screening programs among under-screened populations. • Outreach and education activities tailored to specific target groups in population could enhance level of the cervical cancer screening uptake.
