Evaluating human papillomavirus (HPV) self-sampling among Latinas in the United States: A systematic review.

Background: Latinas experience the greatest cervical cancer incidence compared with other ethnic/racial groups in the United States (US) due in part to significant disparities in screening uptake. Social and structural conditions that impede access to and participation in screening include language barriers, concerns about documentation status, logistical issues (e.g., transportation, limited clinic hours), and cultural beliefs regarding modesty and promiscuity. To overcome these challenges, self-sampling for human papillomavirus (HPV) DNA testing has emerged as a potentially promising method for promoting cervical cancer screening among this population. Thus, this systematic review aimed to assess the acceptability of HPV self-sampling among US Latinas.

Methods: Using EBSCOhost and PubMed databases, we searched for studies published in the past two decades (2003-2023) that described participation in HPV self-sampling among Latinas. Eleven articles met inclusion criteria.

Results: The majority of studies were conducted in Florida, California, and Puerto Rico, were single-arm designs, and involved the use of community health workers and Spanish-language materials (e.g., brochures). Across studies, the majority of participants reported that self-sampling was acceptable with respect to ease of use, comfort (lack of pain), privacy, and convenience; however, some women were concerned about the accuracy of self-sampling or whether they had performed sample collection correctly.

Conclusion: Given the high acceptability, self-collection of cervicovaginal samples for HPV testing may offer a feasible option for enhancing participation in cervical cancer screening in this population that encounters significant barriers to screening.
