Demographic information and blood samples were collected from participants at diagnosis of human immunodeficiency virus (HIV) infection between April and June 2023. TDR and molecular transmission networks were analyzed based on partial pol sequences via the Stanford HIV drug resistance database and HIV-TRACE, respectively. Logistic regression was utilized to identify factors associated with TDR.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>HIV drug resistance genotyping was successfully performed on plasma samples from 6654 individuals. The overall TDR prevalence was 11.4% (95% confidence interval [CI], 10.6%\u201312.2%). Resistance to nonnucleoside reverse transcriptase inhibitors (NNRTIs), nucleoside reverse transcriptase inhibitors (NRTIs), protease inhibitors (PIs), and integrase strand transfer inhibitors (INSTIs) was 7.9%, 0.8%, 2.4%, and 1.0%, respectively. TDR to efavirenz\/nevirapine (EFV\/NVP) was 6.5%. According to the surveillance drug resistance mutation list, the prevalence of TDR to total, NNRTIs, NRTIs, PIs, and INSTIs was 8.2%, 6.4%, 1.0%, 0.7%, and 0.4%. Multivariable analysis linked TDR to non-Han ethnicity (adjusted odds ratio [AOR], 1.45 [95% CI, 1.17\u20131.79]), unknown transmission routes (AOR, 2.56 [95% CI, 1.33\u20134.90]), and CD4 \u2265500 cells\/\u03bcL (AOR, 1.29 [95% CI, 1.05\u20131.58]).
