ABSTRACT
Few large studies evaluated the effects of time trends on virologic suppression in people living with HIV/AIDS (PLWHA) in China. To address this, An retrospective observational longitudinal study was conducted. We examined annual trends in the rate of virologic suppression, the viral load at the time of virologic suppression, and other determinants of virologic suppression in Zhejiang Province, China in PLWHA between January 2013 and July 2018. Patients who received a treatment regimen for at least 24 weeks were included. Virologic suppression was defined as VL ≤50 copies/mL. Generalized estimating equation logistic regression models were used to adjust for covariates. We included 16,265 patients with 45023 tests. The proportion of patients who experienced an unsuccessful virologic outcome decreased continuously throughout the observation period (18.14% to 6.64%). Time was significantly negatively associated with detectable VL (all ORs <1). Other factors were positively associated with detectable VL, including patients <30 years of age, single, non-adherent to treatment, and with a follow-up CD4 count <200 cells/µL. Patients infected through homosexual transmission and those with a longer ART duration were more likely to reach virologic suppression. We demonstrated outstanding time trend improvements in the virological outcomes of PLWHA in China.
