Understanding the Role of Voluntary Counseling and Testing (VCT)‎ in HIV Prevention in Nantong, China

الملخص EN

Voluntary counseling and testing (VCT) service plays an essential part in the prevention of human immunodeficiency virus (HIV) infection.

The purpose of this study was to investigate the characteristics of participants and analyze the major factors of HIV infection in VCT in Nantong, China.

This study was conducted between January 2010 and December 2015, based on the responses to questionnaires and blood test results retrieved from the Chinese National HIV/AIDS Comprehensive Control Information System (CNHCCIS).

Multivariate logistic regression analyses were used to identify factors related to HIV infection.

Differences between first-time testers and repeat testers were assessed using the chi-squared or Fisher test.

Over six years, a total of 11,560 VCT participants were included, and 420 cases were confirmed to be HIV-positive.

Overall, the annual number of participants was relatively stable with a mean of 1927, while there was a rapid increase in the HIV detection rate (from 1.03% in 2010 to 7.52% in 2015).

In multivariate analysis, referral counseling and having a HIV-positive spouse/fixed sex partners were found to be significantly associated with HIV infection among all participants, while being unmarried or divorced, having commercial heterosexual behaviors, and male-male sexual behaviors are additional HIV-related factors for males.

Compared to first-time testers, repeat testers were more willing to engage in high-risk sexual behaviors and had higher HIV detection rates (P<0.001).

In conclusion, the HIV epidemic in Nantong is still not controlled.

Therefore, in the future, it is critical to expand VCT services to increase the detection rate of HIV, which can prevent the transmission of HIV effectively.
