Characteristics and Associated Factors of Partner Service Uptake Cascade Among Newly Reported HIV/AIDS Diagnosed in Southeastern China, 2022: Corss-Sectional Survey
ABSTRACT
Background:
HIV notification and testing uptake integrated into partner service (PS) practices among HIV-positive individuals has been proven to be an efficient approach for case finding that has been implemented for decades. The current status and associated factors of the PS uptake cascade in the real world are scarce, especially within the nonmarital partnerships.
Objective:
To describe the current status of HIV partner service, and mainly focused on exploring factors associated with testing and HIV positivity of nonmarital partner.
Methods:
We recruited newly diagnosed sexually transmitted HIV-positive individuals in 2022, Zhejiang Province as the index case, and offered them partner service (PS). We analyzed the percentage of the PS uptake cascade from both the perspective of the sexual partner and the index case. We evaluated the factors associated with HIV test uptake and HIV positivity of nonmarital sexual partners at the index case level.
Results:
In this study, 3666 index cases were recruited, and they enumerated 2934 sex partners (17.9% of all recalled sex partners). Almost half (49.1%, 1442/2934) of the enumerated sex partners had an HIV test, with an HIV-positive rate of 28.9% (417/1442). Heterosexual commercial partners had the lowest percentage of being enumerated (10.3%, 441/4292) and the highest HIV positive rate (37.4%, 40/107). At the index case level, 46.0% (1688/3666) of the index cases enumerated at least one nonmarital sex partner, 52.7% (890/1666) had sex partner tested HIV, and 31.0% (276/890) had at least one nonmarital sex partner test positive. The determinants of the PS uptake cascade in nonmarital partnerships have been identified to be gender, age, transmission type and regular partner.
Conclusions:
More efforts should be made to improve partner service practices among HIV-positive individuals, and address the gap in partner enumeration/notification, especially for nonmarital partnership. Additionally, enhancing PS operational skills among healthcare personnel to increase the overall efficiency of PS uptake in China.
