Abstract:
Objective:To analyze characteristics of mortality density and the influencing factors of HIV/AIDS after diagnosis in Jiamusi of Heilongjiang province.Methods:The data were retrieved from HIV/AIDS Comprehensive Response Information System and selected cases diagnosed with HIV/AIDS in Jiamusi of Heilongjiang province during 2010-2020 and aged 15 years or older as the study objects. The method of retrospective cohort study was used to collect baseline and follow-up information, and characteristics of mortality density after HIV diagnosis were described. Death after HIV diagnosis was divided into 1-6 months, 7-12 months, and ≥13 months after HIV diagnosis. The Cox proportional hazards model was used to analyze the associated factors of mortality density within six months after HIV diagnosis. Excel 2019 and SPSS 22.0 software were used for data processing and statistical analysis.Results:A total of 953 HIV/AIDS with 173 deaths were included during the study period. Most HIV/AIDS were men (89.19%, 850/953), single or divorced or widowed (76.50%, 729/953), educated in middle school and lower level (51.84%, 494/953), and men who have sex with men (77.02%, 734/953). There was a cumulative follow-up of 3 944.59 person-years, with an overall mortality density of 4.39 (95% CI: 3.79-5.07)/100 person- years. The mortality density was highest in 21.60 (95% CI: 18.04-25.86) 100 person-years within the first six months after diagnosis, then decreased to 2.02 (95% CI: 1.59-2.58)/100 person-years over 13 months or more after HIV diagnosis. HIV/AIDS who died within the first six months after diagnosis had a higher proportion of first CD4 +T lymphocytes (CD4) counts untested (51.61%, 48/93) and AIDS-related deaths (32.26%, 30/93). In the multivariate analysis of the Cox proportional hazards regression model, mortality density within the first six months after HIV diagnosis was greater among HIV/AIDS who were older at diagnosis, detected by medical institutions, with lower first CD4 counts or no testing, and never receiving antiretroviral therapy (ART). Conclusions:Mortality density was generally low in Jiamusi of Heilongjiang province during 2010-2020 and declined over the follow-up time. However, early diagnosis and immediate ART initiation should be strengthened. Attention should also be paid to follow-up care management and referral services for HIV/AIDS within the first six months after HIV diagnosis to reduce the risk of death after HIV diagnosis.
