Uptake and predictors of anal cancer screening in men who have sex with men.

OBJECTIVES We investigated attitudes about and acceptance of anal Papanicolaou (Pap) screening among men who have sex with men (MSM). METHODS Free anal Pap screening (cytology) was offered to 1742 MSM in the Multicenter AIDS Cohort Study, who reported history of, attitudes about, and experience with screening. We explored predictors of declining screening with multivariate logistic regression. RESULTS A history of anal Pap screening was uncommon among non-HIV-infected MSM, but more common among HIV-infected MSM (10% vs 39%; P < .001). Most participants expressed moderate or strong interest in screening (86%), no anxiety about screening (66%), and a strong belief in the utility of screening (65%). Acceptance of screening during this study was high (85%) across all 4 US sites. Among those screened, most reported it was "not a big deal" or "not as bad as expected," and 3% reported that it was "scary." Declining to have screening was associated with Black race, anxiety about screening, and low interest, but not age or HIV status. CONCLUSIONS This study demonstrated high acceptance of anal Pap screening among both HIV-infected and non-HIV-infected MSM across 4 US sites.
