Beliefs About Anal Cancer among HIV-Infected Women: Barriers and Motivators to Participation in Research.

BACKGROUND

Infection with the human immunodeficiency virus (HIV) remains associated with a greater risk of anal cancer, despite widespread use of combination antiretroviral therapy. Evidence concerning the acceptability of anal cancer screening gives little attention to women. Because HIV-infected women have a high prevalence of depression and history of sexual trauma, understanding acceptability among this group is critical.

PURPOSE: We sought to assess barriers and motivators to participation in anal cancer screening research among a racial/ethnically diverse HIV-infected female population.

METHODS

We conducted a survey based on the Health Belief Model to identify characteristics of women willing to participate in anal cancer screening research (n = 200). Bivariate analyses examined associations between willingness to participate and sociodemographics, clinical characteristics, and health beliefs. Logistic regression modeled willingness to participate in research.

MAIN FINDINGS: Of the women who participated, 37% screened positive for depression, 43% reported a high trauma history, and 36% screened positive for posttraumatic stress disorder. Overall, 65% reported willingness to participate in research. Those likely to participate were older, reported intravenous drug use as their HIV risk factor, and had a history of prior high-resolution anoscopy (HRA) compared with those unwilling to participate. The most commonly reported barrier to anal Pap testing was fear of pain. In adjusted analyses, a lack of fear of pain and prior experience with HRA significantly predicted willingness to participate.

CONCLUSIONS

Findings suggest that, to increase participation in anal Pap and HRA-related research for HIV-infected women, a single approach may not be adequate. Rather, we must harness patients' previous experiences and address psychosocial and financial concerns to overcome barriers to participation.
