Abstract: The data came from the case information of HIV/AIDS cases in Guang'an City reported by the National AIDS Comprehensive Prevention and Control Information System (NACIS) from 2013 to 2023. The influencing factors of deaths of HIV/AIDS cases were analysed by using logistic regression model. The results showed there were 8803 cases of HIV/AIDS in Guang'an City from 2013 to 2023, with 2489 deaths, the case-fatality rate was 28.27%. Of the deaths, AIDS accounted for 61.91%, males for 86.86%, diagnoses at age 55 and above for 68.62%, farmers for 72.32%, individuals with spouses for 55.56%, education levels below primary school for 74.25%, heterosexual transmission for 95.22%, medical institutions for 73.04%, first CD4+ T lymphocyte counts not examined or less than 200 cells/μL for 62.43%, and those not receiving antiretroviral therapy (ART) or with delayed ART for 66.05%. Results from the multivariate Logistic regression analysis showed that HIV infection, being female, spouse, being from non-medical institutions, age at diagnosis <35 years old and timely treatment were associated with lower probability of death. Cases with education level of primary school or below, age at diagnosis ≥55, without CD4+T lymphocyte examination at the first visit, and untreated had a higher probability of death. Both HIV-infected individuals and AIDS patients in the treatment group had significantly longer survival times than those in the untreated group (P<0.05).
