Sustained viral suppression in adolescents and young adults living with HIV (AYALWH) is necessary for epidemic control. We evaluated facility and individual correlates of viral suppression using programmatic data from AYALWH between ages 10 and 24 years at 24 HIV clinics in Kenya. Binomial regression was used to evaluate correlates of viral load (VL) suppression (,1,000 copies/ ml). Of 5,316 AYALWH on antiretroviral therapy $6 months, 2,081 (39%) had VLs available in the medical record, of which 76% were virally suppressed. In multivariable analyses, antiretroviral therapy initiation among AYALWH older than 10 years was associated with higher viral suppression than initiation younger than 10 years (adjusted risk ratio [aRR] 10-14 5 1.03, 95% confidence interval [CI] 0.97-1.10; aRR 15-19 5 1.30, 95% CI 1.19-1.41; aRR 20-24 5 1.43, 95% CI 1.24-1.63). Facilities with both youth-friendly services (YFS) and trained providers had significantly higher VL suppression compared with facilities without YFS or trained providers (adjusted odds ratio: 2.07, 95% CI: 1.71-2.52). Viral suppression remains suboptimal among AYALWH. YFS and trained providers plus greater use of VL data may help increase viral suppression among AYALWH.
