Median days from symptom onset to healthcare presentation were determined and risk factors for late presentation (&gt;60 days) were assessed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>RESULTS<\/jats:title>\n                    <jats:p>Among 158 patients (median age 20 years, IQR 17\u201323), 53.6% had pulmonary TB, 39.9% extrapulmonary disease, and 5.7% disseminated disease; 25.3% had cavities. Social risk factors were present in 32.3% of patients. Median delay to presentation was 45 days (IQR 14\u201396), with 38.7% presenting after two months. Delays were longer in patients with incarceration, drug misuse, or mental health issues, though not statistically significant. Patients with social risk factors were more likely to receive observed therapy (OR 2.65, IQR 1.27\u20135.64).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>CONCLUSIONS<\/jats:title>\n                    <jats:p>AYA with TB in this setting experienced delays in healthcare presentation and a quarter had cavitary disease.
