Self-collected vaginal swabs for HPV screening: An exploratory study of rural Black Mississippi women

Objectives To determine the post-procedure acceptability of self-collecting a vaginal swab for HPV testing among a highly impoverished and geographically isolated population of medically underserved Black women residing in the Mississippi Delta. Further, to test correlates of reporting that self-collection is preferred over Pap testing. Finally, to determine the prevalence of any of 13 high-risk HPV types among this population and the correlates of testing positive. Methods Eighty-eight women were recruited from two churches located in different towns of the Mississippi Delta. After completing a survey, women were provided instructions for self-collecting a cervico-vaginal swab and completing a post-collection survey. Specimens were tested for 13 oncogenic HPV types. Due to the exploratory nature of the study, significance was defined by a 0.15 alpha-level. Results Comfort levels with self-collection were high: 78.4% indicated a preference for self-collecting a specimen compared to Pap testing. Overall, 24 women (28.7%) tested positive for one or more of the 13 HPV types. Significant associations with testing positive were found for women having sex with females (P = 0.09), those never having an abnormal Pap (P = 0.06), younger women (P = 0.10), those with greater fatalism scores (P = 0.006), and those having less trust in doctors (P = 0.001). Conclusions Black rural women from the deep-south are generally comfortable self-collecting cervico-vaginal swabs for HPV testing. Given that nearly 30% tested positive for oncogenic HPV, and that fatalism as well a lack of trust in doctors predicted prevalence, a reasonable screening alternative to Pap testing may be community-based testing for HPV using self-collected vaginal swabs.
