Initial follow-up and CD4+ T cell count test of newly reported students HIV cases in China, 2013-2017 / 中华预防医学杂志

ABSTRACT

Objective@#To analyze first follow-up and CD4+ T (CD4) cell count test of newly reported students HIV cases in China from 2013 to 2017.@*Methods@#Data were collected from both Case Reporting Cards and Follow-up Cards from China Information System for HIV/AIDS Control and Prevention between 1st January 2013 and 31st December 2017. The inclusion criteria are 15-24 years old students who were newly diagnosed with HIV infection. Logistic regression model was used to analyze relevant factors of the first CD4 test results less than 200 CD4 cells/μl.@*Results@#There were 12 037 newly diagnosed students HIV cases from 2013 to 2017. Most cases were male (97.7%), 19-22 years old (65.1%) and Han ethnicity (90.5%). At the time of diagnosis, the route of HIV infection was most frequently homosexual contact (82.2%). The majority of cases (46.9%) were diagnosed at HIV voluntary counseling and testing (VCT) location. About 2 465 (20.6%) students had unprotected intercourse in the past 3 months, of which 1 387 (56.8%) had 1 sexual partner, 610 (25.0%) with 2 sexual partners, 273 (11.2%) with 3 partners and 170 (7.0%) with more than 4 partners. 11.0% and 28.9% of cases had initial CD4 counts less than 200 cells/μl and 200-349 cells/μl. Compared to the male, younger than 18 years old and diagnosed at VCT location, female (OR=2.09, 95%CI 1.51-2.89), aged 21 to 22 years (OR=1.25, 95%CI 1.06-1.47), diagnosed in hospital settings (OR=2.20, 95%CI 1.89-2.57) and preoperative testing (OR=1.36, 95%CI 1.07-1.73) had greater proportion of the first CD4 test result less than 200 CD4 cells/μl.@*Conclusion@#The number of newly diagnosed students HIV cases significantly increased in past 5 years, and the proportion of late diagnosis was high. Female, aged 21 to 22 years, diagnosed in hospital settings and preoperative testing were related to the first CD4 test result less than 200 CD4 cells/μl.
