[Characteristics and influencing factors of HIV detection among HIV/AIDS patients in Zhejiang province in 2012].

OBJECTIVE: To assess the characteristics and influencing factors of HIV detection among HIV/AIDS patients in Zhejiang province.

METHODS: HIV/AIDS cases information were selected from the case reporting database of HIV/AIDS Comprehensive Response Information Management System in Zhejiang province in 2012. HIV late diagnosed patients and early diagnosed patients were classified by first CD4(+) T cell counts (less than 200 cells/µl) and positive BED HIV-1 capture enzyme immunoassay (BED-CEIA) tests result. A total of 1 894 patients were enrolled and 1 383 patients were served by BED-CEIA tests. Information including social demographics, transmission routes, test history were collected for analysis. The univariate and multivariate logistic regression methods was used to analyze the characteristics of HIV detection and related influence factors.

RESULTS: Among 1 894 cases, 26.4% (500/1 894) were late diagnosed and 19.2% (361/1 883) were early diagnosed. The highest rate of late diagnose (36.5%, 27/74) and lowest rate of early diagnose(3.9%, 14/74) were both in Lishui city. Age, transmission routes, HIV testing style, permanent residence were independent reasons for late diagnosed. Compared with patients < 20 years old, participants over 50 years old had higher risk of late diagnosed (OR = 2.885, P < 0.05); patients with homosexual behaviors had lower risk of late diagnosed than patients with heterosexual behaviors and other high risk behaviors(OR = 1.471 or 2.416, P < 0.05). Age, marriage status, HIV testing style, transmission routes, the detection unit, permanent residence were independent reasons for early diagnosed. The risky of early diagnosed among patients ≥ 50 years old were 0.432 times than that among patients < 20 years old (OR = 0.432, P < 0.05). Compared with unmarried participants, married patients had lower risk of early diagnosed (OR = 0.603, P < 0.05). Compared with homosexual behaviors, high risk heterosexual behaviors and other risk behavior significantly reduced the chance of early diagnosis(OR = 0.719 or 0.763, P < 0.05).

CONCLUSION: Late diagnoses and early diagnosis coexist among reported HIV/AIDS in Zhejiang province in 2012. The main reasons for late diagnosis of HIV infection are older age, heterosexual behaviors and other risk behavior, testing in hospital, living in other province. The main reasons for early diagnosis of HIV infection are young age, unmarried, homosexual behaviors, testing in CDC, living in Zhejiang province.
