Overview

Background Human papillomavirus (HPV) infection is prevalent among people who are sexually active. This study aimed to compare the levels of behavioral intention to receive free clinician-collected and self-collected samples for HPV DNA testing and its determinants between heterosexual males and females in Hong Kong, China. Methods This is a secondary analysis of a territory-wide survey conducted in Hong Kong between May 2021 and March 2022. Participants were sexually active adult Hong Kong residents who were able to communicate in English or Chinese. Invitation letters were mailed to residential addresses that were geographically randomly selected. All sexually active adult household members were invited to complete a self-administered online survey. Multivariate logistic regression analyses were fitted. Results Out of 45,394 invitations, 1265 surveys were collected, and 487 heterosexual males and 741 females were included in the analysis. More females than heterosexual males intended to take up free clinician-collected samples for HPV DNA testing (76.7% versus 62.2%, p  < 0.001). Similar proportion of heterosexual males and females intended to receive free self-collected samples for HPV DNA testing (67.8% versus 72.6%, p  = 0.20). Perceived existing treatment could control sexually transmitted infections (STI) (treatment control), more concerned about STI (concern), perceived more benefits, cue to action (suggested by significant others), and self-efficacy related to HPV testing were associated with higher intention to receive clinician-collected samples for HPV testing in both groups. Heterosexual males who perceived more severe symptoms if contracted STI (identity), longer duration of STI (timeline), more negative effects of STI on their lives (consequences), more understanding of STI (coherence), and stronger negative emotions if contracted STI (emotions) also had higher behavioral intention to take up clinician-collected samples for HPV testing. In addition, perceived more benefits, cue to action, and self-efficacy related to self-collected samples for HPV DNA testing were associated with behavioral intention to take up such testing in both groups. Conclusions HPV DNA testing was under-utilized in Hong Kong. Free self-collected samples for HPV testing were highly acceptable by both heterosexual males and females. Illness representation of STI and the Health Belief Model could explain intentions to take up HPV DNA testing.
