[Analysis of knowledge and related factors regarding hepatitis C prevention and treatment among female sex workers and men who have sex with men in the Xizang Autonomous Region].

To investigate the knowledge of hepatitis C prevention and treatment and related factors among two groups of female sex workers (FSW) and men who have sex with men (MSM) in the Xizang Autonomous Region (Xizang) to provide a basis for the subsequent development of Hepatitis C publicity and education strategies. From August to September 2021, a special survey was conducted among 1 244 FSW and 234 MSM in 5 districts (counties) of 4 regions in Xizang. A one-on-one face-to-face questionnaire survey was adopted, and the ² test and logistic regression were used to analyze the related factors of awareness of hepatitis C prevention and treatment among FSW and MSM. The awareness rates of hepatitis C prevention and treatment knowledge among FSW and MSM were 35.0% (436/1 244) and 11.1% (26/234), respectively. Multivariate logistic regression analysis revealed that the positive related factors of FSW' awareness of hepatitis C prevention and treatment knowledge among those who had high school or technical secondary school education (a=4.72, 95%: 3.30-6.74) and college education or above (a=2.24, 95%: 1.58-3.18), those who experienced self-perceived risk of HCV infection (a=1.87, 95%: 1.43-2.45), negative related factors included married or cohabiting (a=0.58, 95%: 0.35-0.95), divorce or windowless (a=0.44, 95%: 0.27-0.72), no condom was used in the most recent commercial sexual activity (a=0.54, 95%: 0.43-0.69). The positive related factors of MSM's awareness of hepatitis C prevention and treatment knowledge were over 40 years old (a=8.65, 95%: 3.19-23.42) and having a self-perceived risk of HCV infection (a=6.25, 95%: 2.50-15.61). The awareness rate of hepatitis C prevention and treatment among FSW and MSM was relatively low in Xizang in 2021 and urgently needs to be improved. It is necessary to formulate targeted publicity strategies based on the characteristics of these two groups of people, increase publicity efforts, and expand the coverage of knowledge publicity to popularize key points about the clinical manifestations, treatment options, and transmission routes of hepatitis C, and carry out necessary warnings and education.
