In HIV treatment, surveillance of mutations inducing resistance to NRTIs (Nucleoside Reverse Transcriptase Inhibitors) and NNRTIs (Non-Nucleoside Reverse Transcriptase Inhibitors) is important. This study analyzed 2,071 HIV-1 genomic sequences directed to detection of major NRTIs and NNRTIs resistance mutations and viral tropism. CRF08_BC and X4 strain more likely had major NRTIs (adjusted odds ratio (aOR) 3.0, 95% CI 1.182-7.820, p=0.021 and aOR 1.7, 95% CI 1.233-2.368, p=0.001; respectively) and NNRTIs (aOR 3.3, 95% CI 1.281-8.365, p=0.013 and aOR 1.4, 95% CI 1.037-1.977, p=0.029, respectively) resistance mutations. Subtype A1 (aOR 0.2, 95% CI 0.069-0.702, p=0.011) and C (aOR 0.4, 95% CI 0.241-0.648, p<0.001) were associated with major NRTIs resistance mutations. The occurrence of major NRTIs and NNRTIs resistance mutations in HIV subtype A1, C, CRF08_BC, and X4 viruses should be a particular concern. Â
