Syphilis Infection among Drug Users in Different Regions in China - Develop Targeted Intervention Strategy

Weidong Zhang, Gang Zeng and Fan Lv

Aim: To understand the sex behaviors and demographic characteristics associated with syphilis infection among drug users in China, to provide useful information for HIV/AIDS prevention and intervention strategy.

Methods: Convenience sampling method or snowball sampling method was used to recruit drug users. Logistic regression was used to analyse independent association between syphilis and risk behaviours.

Results: Syphilis prevalence in Guangxi Nanning, Xinjiang Kashi and Guangdong Dongguan were 17.5%, 10.4%, and 9.6%, respectively. Factors significantly associated with syphilis in Guangxi Nanning was: female vs. male (OR 8.50; p=0.001); factors significantly associated with syphilis in Xinjiang Kashi were: female vs. male (OR 7.44; p<0.05), married vs. single (OR 2.51; p<0.05), ≤ 9 years vs. more than 9 years (OR 3.06; p<0.05); factors significantly associated with syphilis in Guangdong Dongguan were: female vs. male (OR 4.52; p=0.001), married vs. single (OR 3.96; p=0.001), ≤ 9 years education versus > 9 years (OR 3.12; p<0.01), IDU versus Non-IDU (OR 2.81; p<0.05).

Conclusion: Now, the major mode of HIV transmission in China is sexual transmission, targeted prevention and intervention should focus on at-risk groups.
