  "abstract": "Background: Late HIV diagnosis is a critical challenge for controlling the transmission; if not addressed, it could inevitably slow or reverse current progress toward the UNAIDS 95-95-95 targets by 2030.\n\nMethods: We conduct a retrospective study of a full registry of 1404 HIV cases in Yinzhou District (2001–2025), China. Adjusted relative ratio (aRR), posterior relative ratio (RR), Global Moran's I index, and adjusted hazard ratios (aHR) of late HIV diagnosis were calculated using Poisson's regression analysis, subgroup analysis, spatial autocorrelation analysis, and Cox regression, respectively.\n\nResults: The proportion of late HIV diagnosis was 76.4% in Yinzhou. Older age (aRR = 1.003, 95%CI: 1.001–1.006) at HIV diagnosis was significantly associated with a higher risk of late diagnosis. Patients who tested voluntarily (aRR = 0.918, 95%CI: 0.849–0.993) and living in the northwest (aRR = 0.933, 95%CI: 0.876–0.994) were associated with a lower risk. The northwest was a cold spot, and the central and southeast areas were hotspots for late HIV diagnosis (global Moran's I = 0.65, p < 0.001). Patients aged 60 and over and tested non-voluntarily was identified as a priority subgroup (posterior RR = 1.097, 95%PI: 1.013–1.174). Late presenters had a higher hazard of death than non-late presenters (aHR = 3.03, 95%CI: 1.04–8.84).\n\nConclusion: We identified a priority subgroup at high absolute risk and a hotspot for late HIV diagnosis in Yinzhou. This finding provides evidence for developing targeted intervention strategies.",
