Behaviors on Drug-Abuse & Prevalence of Sexually Transmitted Diseases among Drug Users in Tianjin, China, from 2011 to 2015
OBJECTIVE:
To
understand the change of behavioral characteristics among drug users (DUS) in
Tianjin and the prevalence rates of major sexually transmitted disease
infections. A series of cross-sectional surveys were used.
METHODS:
Between
April and June, 2011 to 2015, a cross-sectional survey with face to face
interview, was undertaken. Interview was conducted among DUS who entered the
drug rehabilitation center and blood samples were drawn to test for
HIV/syphilis/HCV infections. Multivariate logistic regression analysis was used
to analyze the relationship between the infection of major sexually transmitted
diseases and drug abuse or sexual behavior.
RESULTS:
2 000 DUS
were included during the 5-year study, with the average age of the DUS as 34.5
± 8.7. Female accounted for 17.9% and club drug (new drugs) users accounted
45.4% of the participants, with its proportion increasing over the years.
Comparing to traditional drug users, club drug users showed more sexual
activities with partners, but lower proportion of condom use. Prevalence rates
of HIV/Syphilis and HCV were 1.3%, 11.0%, 52.0%, respectively. The prevalence
of syphilis among club drug users was significantly higher than those on
traditional-drug use (χ(2)=67.778,P<0.001). Data from Binary logistic
regression analysis showed that club drug use (adjusted OR=1.607, 95%
CI:1.191-2.170) and females (adjusted OR=5.287, 95%CI: 3.824-7.311) were
associated with syphilis infection among DUS.
CONCLUSION:
Drug
abuse behavior changed among the drug abuse in Tianjin. Proportion of club drug
use continued to increase so as the risk of infected sexually transmitted
diseases.
