Objective: To understand the cognition, willingness to test and influencing factors of hepatitis C (HCV) based on social software for men who have sex with men (MSM). Methods: An online questionnaire was used to investigate the target population of Blued platform users, including general demographic characteristics, sexual behavior, drug abuse behavior, cognition of hepatitis C prevention and treatment, past hepatitis C testing status and future testing willingness. There were 14 questions in the cognition part, and answering 10 or more questions were defined as "knowing" . Cognition rate, willingness to test and related influencing factors of hepatitis C were analyzed in different characteristics population. Data were analyzed by univariate and multivariate logistic regression. Results: A total of 1800 valid questionnaires were completed, of which 58.9% (1 061/1 800) had heard of hepatitis C, and the overall cognition rate of hepatitis C was 33.5% (603/1 800). The cognition rate of hepatitis C among those aged 30 years old, monthly income among RMB 5 000~10 000, high school education or above, and previous HIV testing [42.5% (371/873), 36.7% (191/520), 35.1% (584/1 663) and 37.4% (544/1453)] was considerably higher than those of the corresponding low-age, low-income, low-educated, not having HIV testing and not insisting on condom use, and the differences were statistically significant (P < 0.05). The proportion of respondents who were willing to undergo hepatitis C testing in the next 3 months was 82.5% (851/1 031). The proportion of respondents who were tested for HIV in the past, had anal sex in the past 6 months and had high-risk behaviors [85.2% (766/899), 86.1% (609/707) and 86.6% (610/704)] was considerably higher than those who had not been tested for HIV, had no anal sex and had no high-risk behaviors in the past 6 months, and the differences were statistically significant (P < 0.05). Conclusion: The survey respondents have a low cognition rate of hepatitis C, but have a higher willingness to test. Targeted publicity and education should be strengthened for this population, and convenient conditions should be provided to promote regular testing.
目的： 了解社交软件上男性同性性行为者（MSM）的丙型肝炎（简称"丙肝"）知识知晓、检测意愿情况及其影响因素。 方法： 采用网络问卷，对Blued平台用户的目标人群进行调查，内容包括一般人口学特征、性行为、吸毒行为、丙肝防治知识、丙肝既往检测情况和未来检测意愿等。知识部分共14题，以答对10题及以上定义为"知晓"。分析不同特征人群丙肝知识知晓率、检测意愿及相关影响因素。对数据采用单因素、多因素logistic回归分析。 结果： 共完成1 800份有效问卷，其中58.9%（1 061/1 800）听说过丙肝，总体丙肝知识知晓率为33.5% (603/1 800)。年龄30岁、月收入在5 000～10 000元、高中及以上学历、既往做过人类免疫缺陷病毒（HIV）检测者，其丙肝知识知晓率分别为42.5%（371/873）、36.7%（191/520）、35.1%（584/1 663）和37.4%（544/1 453），高于相应低年龄、低收入、低学历、未做过HIV检测及未坚持使用安全套者，差异均有统计学意义（P值均< 0.05）。调查对象未来3个月愿意进行丙肝检测的比例为82.5%（851/1 031）；既往做过HIV检测、近6个月有肛交行为以及有高风险行为者，其愿意检测的比例分别为85.2%（766/899）、86.1%（609/707）和86.6%（610/704），高于未做过HIV检测、近6个月无肛交及无高风险行为者，差异均有统计学意义（P值均< 0.05）。 结论： 调查对象丙肝知识知晓率较低，但有较高的检测意愿，应针对该人群加强针对性宣传教育，并提供便利条件促进其定期检测。.
