Post-exposure prophylaxis(PEP)usage and related factors among college MSM based on structural equation modeling
Objective To analyze the use of post-exposure prophylaxis(PEP)medication among university men who have sex with men(MSM)and explore related factors,providing a basis for future PEP promotion efforts.Methods College MSM aged 18 years and above from four cities(Hangzhou,Ningbo,Jiaxing,and Jinhua)were recruited as participants.Non-probability sampling was employed,and local community organizations were recruited and administered the surveys.Data were collected through face-to-face or telephone interviews regarding sociodemographic characteristics,HIV/AIDS prevention knowledge,risky sexual behaviors,HIV testing,condom use efficacy,and PEP medication use.An exploratory factor analysis was conducted using SPSS 25.0,and structural equation modeling(SEM)was performed using AMOS 23.0 to analyze the relationships and influences between variables.Results A total of 671 college MSM were surveyed,with a PEP usage rate of 9.1％(61/671).The adjusted SEM model exhibited a good fit,with x2/df=1.43,RMSEA=0.03,and all incremental and parsimonious fit indices exceeding reference values(＞0.9 and＞0.5,respectively).Model results indicated that information sources exerted the greatest influence on PEP usage among MSM students,followed by online casual sexual encounters,HIV testing,condom use efficacy,and HIV/AIDS prevention knowledge,with total effect values of-0.25,0.15,0.15,-0.08,and 0.01,respectively.Conclusions HIV/AIDS prevention knowledge,casual online sexual encounters,HIV testing,information sources,and condom use efficacy all influence PEP usage among college MSM to varying degrees.Enhancing the dissemination of PEP knowledge is essential to ensure that MSM at risk of exposure can access PEP in a timely manner.
