Background: Adolescents and young adults (AYA) living with HIV have been shown to have lower rates of viral load testing and viral suppression as compared to older adults. We examined trends over time and predictors of HIV viral load monitoring and viral suppression among AYA in a large HIV treatment programme in Dar es Salaam, Tanzania. Methods: We analysed longitudinal data of AYA aged 10–24 years initiated on antiretroviral therapy between January 2017 and October 2022. Trend models were used to assess changes in HIV viral load testing and viral suppression by calendar year. Generalised estimating equations were used to examine the relationship of sociodemographic and clinical factors with HIV viral load testing and viral suppression. Results: Out of 15,759 AYA, the percentage of those who received a 6‐month HIV viral load testing increased from 40.6% in 2017 to 64.7% in 2022 and, a notable annual increase of 5.6% (p < 0.001). A higher HIV viral load testing uptake was observed among 20‐ to 24‐year‐olds (87.7%) compared to 10‐ to 19‐year‐olds (80.2%) (p < 0.001). The likelihood of not receiving an HIV viral load test within 12 months of antiretroviral therapy initiation was higher among 10‐ to 19‐year‐olds (adjusted odds ratio [aOR] = 1.7; 95% confidence interval [CI] = 1.4–2.0), advanced HIV disease (aOR = 1.3; 95% CI = 1.12–1.53), normal nutrition status at enrolment aOR 2.6 (95% CI = 1.59–4.26) and initiation of non‐nucleoside reverse transcriptase inhibitors regimen aOR 1.2 (95% CI = 1.08–1.34). The proportion of AYA with viral suppression increased from 83.0% in 2017 to 94.6% in 2022. Notably, the overall trend in viral suppression increased significantly at 2.4% annually. The risk of not achieving viral suppression was greater among 10‐ to 14‐year‐olds (aOR = 2; 95% CI = 1.75–2.43) and 15‐ to 19‐year‐olds (aOR = 1.4; 95% CI = 1.24–1.58) as compared to 20–24 years; being male (aOR = 1.16; 95% CI = 1.02–1.32); undernourished (aOR = 1.53; 95% CI = 1.17–1.99); in WHO Stage II (aOR = 1.16; 95% CI = 1.02–1.33) and III (aOR = 1.21; 95% CI = 1.03–1.42) and being on an non‐nucleoside reverse transcriptase inhibitors regimen (aOR = 1.32; 95% CI = 1.18–1.48). Conclusion: HIV viral load testing uptake at 6 months of antiretroviral therapy initiation and viral suppression increased from 2017 to 2022; however, overall HIV viral load testing was suboptimal. Demographic and clinical characteristics can be used to identify AYA at greater risk for not having HIV viral load test and not achieving viral suppression. [ABSTRACT FROM AUTHOR]
