Abstract：Objective To analyze the epidemiological characteristics and determinants of late-diagnosed cases among newly reported sexually transmitted HIV infectors/AIDS patients. Methods Based on databases from the National Information System for Comprehensive HIV/AIDS Prevention and Control, newly reported sexually transmitted HIV/AIDS cases in Hubei Province from January 1, 2012 to December 31, 2016 were chosen to analyze the epidemiological characteristics of late-diagnosed cases and compare the changing trend of the case proportions. Multivariate logistic regression analysis was performed to determine the factors influencing the cases with late diagnosis. Results A total of 11,832 newly reported sexually transmitted HIV/AIDS cases were reported in Hubei Province during 2012-2016. The proportion of late-diagnosed cases was 39.92% (4,723/11,832), and a statistical significance was found in the proportion of late diagnosis between homosexual and heterosexual transmitted cases (27.09% vs. 49.13%, χ2=581.609,P<0.001). Among 4,508 late-diagnosed cases (excluding 215 late-diagnosed cases by calculation), 79.41% cases were males, 63.38% were mainly diagnosed at the ages of 35-64 years, 96.69% were the Hans, 68.88% had education background of junior middle school and below, 71.78% were transmitted heterosexually, and 71.32% were diagnosed by medical institutions. Multivariate logistic regression analysis revealed that female, advanced age, heterosexual transmission and cases diagnosed by medical institutions were the main factors for late diagnosis. Geographic difference was identified in the proportion of the late-diagnosed cases. Conclusions Late diagnosis remains relatively high in newly reported sexually transmitted HIV infectors/AIDS patients in Hubei Province. It is necessary to adopt targeted case-finding strategies based on epidemiological characteristics of high risk populations with specific routes of transmission, strengthen the roles of provider-initiated HIV testing and counseling (PITC) and voluntary testing and counseling in medical institutions, and take advantage of social groups in scaling up HIV testing among gay population.
