Survey of Prevalence of HIV Infection, Syphilis & HCV Infection & Related Risk Behaviors among Club Drug Users in Zhejiang, 2011
OBJECTIVE:
To
understand the prevalence of HIV infection, syphilis and hepatitis C infection
and related risk behaviors among club drug users in Zhejiang province.
METHODS:
The drug
users were interviewed with questionnaires in 2011 to collect the information
about their demographic characteristics, sexual behaviors, drug use behaviors
and the utilization of intervention services. Blood samples were collected from
them to detect HIV, syphilis and HCV antibodies.
RESULTS:
A total
of 3 253 drug users were surveyed, in which 1 298 were club drug users,
accounted for 39.9%. The proportion of club drug users was high in northern and
central Zhejiang, in females, in age group≤25 years, in local residents and in
those having commercial sexual behaviors during previous 12 months. Of the 1
298 club drug users, 91.2% were methamphetamine users, 0.1% were infected with
HIV (95% CI: 0.0%-0.2%), 8.1% suffered from syphilis (95% CI: 6.6%-9.6%), 17.3%
were infected with HCV (95% CI: 15.2%-19.4%). Among the interviewed club drug
users, 12.7% were aware of AIDS, 9.2% had injecting drug use histories, 29.6%
reported having commercial sex during the previous 12 months, only 33.4%
received free condom and counsel, 14.0% received HIV test. Multivariate
logistic regression analysis indicated that living in central and southern
Zhejiang was associated with syphilis prevalence, HCV infection and injecting
drug use behavior, being female was associated with syphilis prevalence.
Injecting drug use and commercial sex during the previous 12 months were
associated with HCV infection, and injecting drug use and commercial sex during
the previous 12 months were associated with each other. Among the 1 285 club
drug users, males, local residents in Zhejiang and those who never received
free condom or counsel were more likely to have commercial sex.
CONCLUSION:
The
prevalence of syphilis and HCV infection are high and unprotected sexual
behaviors are common among the club drug users in Zhejiang, but less
intervention services were received by them, suggesting that more attention
should be paid to the prevention and control of HIV, HCV infections and
syphilis in club drug users by taking effective intervention measures and
increasing intervention coverage.
