Abstract:
Objective :To investigate the prevalence of hepatitis C virus (HCV) and syphilis among drug users (DUs) in Inner Mongolia Autonomous Region.
Methods :DUs' epidemiological data were collected from 5 national AIDS surveillance sentinels in Inner Mongolia Autonomous Region in 2021 through the National HIV/AIDS Sentinel Surveillance Data Management System, and sexual behaviors, DU behaviors, HIV testing and behavioral interventions were descriptively analyzed. The factors affecting the HCV and syphilis infections were identified among DUs using a multivariable logistic regression model.
Results :A total of 2 019 DUs were enrolled, with a mean age of (43.32±9.88) years. Among the participants, there were 1 958 males (96.98%), 1 830 with local registered residence (90.64%), 1 038 with marriage/cohabitation (51.41%), 1 410 with an educational level of junior high school and above (69.84%), and 1 884 with Han Ethnicity (93.36%). There were 1 605 DUs with use of conventional drugs (79.49%), 283 with use of new drugs (14.02%) and 131 with use of mixed drugs (6.49%), and there were 340 DUs with injection drug use (16.84%), including 41 that shared the needles (12.06%). There were 460 DUs with commercial sexual behaviors in the past year (22.78%). The percentage of HCV and syphilis positive was 23.63% and 3.81%, respectively, while no HIV positive case was detected. In addition, multivariable logistic regression analysis showed that age (40 years- , OR=3.747, 95%CI: 2.161-6.497; 50 years and older, OR=5.302, 95%CI: 3.064-9.177), local registered residence (OR=3.409, 95%CI: 1.935-6.008), use of conventional drugs (OR=1.477, 95%CI: 1.035-2.108), and injection drugs (OR=2.700, 95%CI: 2.067-3.527) caused an increased risk of HCV infections among DUs, and divorced/widowed (OR=3.413, 95%CI: 1.463-7.962) and non-local registered DUs (OR=2.404, 95%CI: 1.304-4.433) had an increased risk of syphilis infections.
Conclusions :Middle-aged men are predominant DUs in national AIDS surveillance sentinels in Inner Mongolia Autonomous Region, and the prevalence of HCV and syphilis infections correlates with age, household registration, marital status, type of drugs used and route of drug use.
