Abstract
Human papillomavirus (HPV) vaccination could reduce HPV infection in men who have sex with men (MSM), but the published statistics on HPV vaccination uptake in MSM were scarce globally. This study estimated the uptake and profiled the service preferences of HPV vaccination of Chinese MSM in Hong Kong. Adult MSM were recruited through non-governmental organizations (NGOs) and online channels for completing an online baseline survey. Factors associated with self-reported history of HPV vaccination were identified using multivariable stepwise logistic regression model. Totally 701 Chinese MSM completed the online baseline survey, with the median age of 30 y (interquartile range [IQR] 26-35, range 18-67), and 23% of them had received HPV vaccination. More than half of vaccinated MSM (72%) rated convenient or very convenient for local HPV vaccination services. Among unvaccinated MSM, 50% considered high cost of HPV vaccine as the barrier of vaccination, 67% expressed willingness to pay below USD 128 per vaccine dose, and 65% preferred receiving vaccination in private clinics. MSM who had taken HIV pre-exposure prophylaxis (PrEP) (p < .001), had been tested for HPV (p = .018), and had (p = .005) multiple regular sex partners in the past 6 months were more likely to be vaccinated. The HPV vaccination uptake of Chinese MSM in Hong Kong remains low (23%), and high HPV vaccine cost is the main barrier. Preventive behaviors (HIV PrEP use and HPV testing) and high-risk sexual behavior (multiple regular sex partners) are potential targets for intervention to increase the uptake of HPV vaccination in MSM.
