Insights
A study in China found a 0.7% HIV prevalence and significant rates of other STDs among male clinic patients. Provider-initiated HIV testing and counseling (PITC) was well-accepted, supporting its wider implementation.
Area of Science:
- Public Health
- Infectious Diseases
- Epidemiology
Background:
- Previous research indicated high STD/HIV prevalence in specific groups in China.
- Limited data existed on STD patterns among male patients in public STD clinics.
- This study aimed to fill that knowledge gap.
Purpose of the Study:
- To investigate STD and HIV prevalence in male STD clinic attendees across China.
- To identify risk factors associated with HIV infection in this population.
- To evaluate the feasibility of Provider-initiated HIV testing and counseling (PITC).
Main Methods:
- A cross-sectional study involving 3243 eligible male patients across 46 public STD clinics in China.
- Data collection included structured questionnaires on demographics and sexual behaviors.
- Laboratory testing for HIV, syphilis, Chlamydia trachomatis, and Neisseria gonorrhoeae infections.
Main Results:
- HIV prevalence was 0.7%; syphilis (10.7%), N. gonorrhoeae (4.3%), and C. trachomatis (6.9%) were more common.
- Higher rates of syphilis and N. gonorrhoeae were observed in Jiangsu Province.
- HIV infection was associated with patients from Guangxi, homosexual/bisexual practices, and intravenous drug use.
Conclusions:
- Modest HIV and substantial other STD prevalence were found in male STD clinic attendees in China.
- PITC was highly accepted (91% agreement), indicating its feasibility.
- Findings support integrating HIV and syphilis PITC into STD clinics.
Background:
Previous studies suggested a high prevalence of STDs including HIV among female sex workers and men who have sex with men in China, but little was known about the prevalence in male patients attending public STD clinics. The aim of this study was to investigate STD patterns and HIV prevalence among male STD clinic attendees in different areas in China and the associated risk factors. The feasibility of Provider-initiated HIV testing and counseling (PITC) was evaluated as well.
Methods:
A cross-sectional study was conducted at 46 public STD clinics in 4 provinces in China. Between July 2009 and September 2009, a total of 3243 eligible subjects were invited to participate in an interview with a structured-questionnaire for collecting socio-demographic characteristics and sexual behavioral information. They also were asked to provide venous blood samples for serological determinations of HIV and syphilis infection, and first void urine specimens for detecting Chlamydia trachomatis and Neisseria gonorrhoeae infections,
Results:
Out of the 3243 eligible patients, 2951(91%) men agreed to take part in the HIV and syphilis testing. The overall prevalence rate of HIV infection was 0.7% while the rates of syphilis, N. gonorrhoeae, C. trachomatis infections were 10.7%, 4.3% and 6.9%, respectively, with the highest syphilis and N. gonorrhoeae rates in Jiangsu Province. Patients from Guangxi province, homosexual/bisexual practices and intravenous drug use were significantly associated with HIV infection in multivariate logistic regression analyses. Provider-initiated HIV testing and counseling (PITC) was well accepted by attendees, with 91% of eligible attendees agreeing to undergo HIV testing and counseling. All HIV positive patients were properly managed accordingly.
Conclusions:
A modest prevalence of HIV infection and substantial prevalence of other STD infections were found among male patients attending public STD clinics in China. The findings further support the introduction of HIV and syphilis PITC strategy into this important setting.
