Adults Aged ≥50 Years Reached by the Centers for Disease Control and Prevention's HIV Testing Programs in the United States and US Dependent Areas, 2019

Objectives: Older adults represent nearly half of people living with HIV in the United States. The objective of this analysis was to describe HIV testing, demographic characteristics, and risks of adults aged >= 50 years (older adults) reached in 2019 by HIV testing programs funded by the Centers for Disease Control and Prevention (CDC). Methods: We collected data from 101 CDC-funded community-based organizations and 61 health departments. All funding recipients submitted deidentified program service data for 2019 through a secure online CDC-supported system. We used multivariable robust Poisson regression to assess the association between demographic and risk characteristics and the proportion of tests that resulted in a new diagnosis. We also assessed the proportion of people who received a positive test result, were linked to HIV medical care, and were interviewed for partner services. Results: During 2019, among 2 452 507 CDC-funded HIV tests provided in the United States, 412 164 (16.8%) were provided to older adults. Among the 1059 (0.26% positivity) older adults with newly diagnosed HIV infection for whom we had data, 582 (68.4%) were linked to HIV medical care within 30 days of diagnosis and 494 (72.1%) were interviewed for partner services. Among the 2858 older adults with previously diagnosed HIV infection, 1321 (46.2%) reported not being in HIV medical care at the time of the test; of those with linkage data, 425 (49.9%) were linked to HIV medical care within 30 days of testing HIV positive. Conclusions: More rapid disease progression and higher morbidity and mortality rates among older adults suggest that services are needed to ensure early diagnosis, rapid linkage, and interview for partner services.

Automated summary

The objective of this analysis was to describe the HIV testing, demographic characteristics, and risks of adults aged >= 50 years reached in 2019 by HIV testing programs funded by the CDC. The results show the need for early diagnosis, rapid linkage, and partner services for older adults.
