HPV: human papillomavirus; HBM: health belief model; OR: crude odds ratios; CI: confidence interval; and AOR: adjusted odds ratios, odds ratios adjusted for significant baseline background characteristics (i.e., history of HPV infection and/or genital warts, and utilization of other HIV/STI prevention services).
