Abstract
PURPOSE: Self-sampling is increasingly being used in screening programs, yet no studies to date have examined the impact of bodily characteristics on self-sampling experiences. Our objective was to assess whether body mass index (BMI) and physical disability were associated with anal self-sampling difficulty.
METHODS: We recruited sexual minority men (SMM) and trans persons in Milwaukee, Wisconsin to participate in an anal cancer screening study. Between January 2020 and August 2022, 240 participants were randomized to a home (n = 120) or clinic (n = 120) screening arm. Home participants received a mailed at-home anal self-sampling kit and were asked to attend a baseline clinic visit where biometric measurements were collected. Participants were asked to complete a survey about their experience with the kit. This research utilized data from participants who used the at-home kit and completed a baseline clinic visit and post-swab survey (n = 82). We assessed the impact of BMI and physical disability on reported body or swab positioning difficulty.
RESULTS: Most participants reported no or little difficulty with body positioning (90.3%) or swab positioning (82.9%). Higher BMI was significantly associated with greater reported difficulty with body positioning (aOR = 1.10, 95% CI 1.003-1.20, p = 0.04) and swab positioning (aOR = 1.11, 95% CI 1.02-1.20, p = 0.01). Although not significant, participants who said body positioning was difficult had 2.79 higher odds of having a physical disability. Specimen adequacy did not differ by BMI category (p = 0.76) or physical disability (p = 0.88).
CONCLUSION: Anal self-sampling may be a viable option to reach obese persons who may be more likely to avoid screening due to weight-related barriers.
