Prevalence and factors associated with late diagnosis among older adults living with HIV in liuzhou, China: 2010-2020.

This paper aimed to quantify and characterize the prevalence and associated factors for late diagnosis in older adults living with human immunodeficiency virus (HIV) in Liuzhou, China, from 2010 to 2020. The characteristics of older adults living with HIV were described separately in time, space and population. Multivariate logistic regression analysis evaluates the factors influencing late diagnosis in HIV-positive adults ≥ 50 years of age. The majority of older adults living with HIV were over 60 years old, male, and with CD4 counts < 200 cells/µl at diagnosis, with most late diagnoses being more likely to report heterosexual transmission. These two factors may potentially provide a positive influence on late diagnosis: older and CD4 counts < 500 cells/µl. In contrast, females and those with homosexual or other transmission provide a negative. These results suggest that late diagnosis of HIV-positive adults ≥ 50 years of age remains a severe and growing epidemiological issue.
