Abbreviations: n = unweighted sample size; CI = Confidence interval; ART = Antiretroviral medications; VL = Viral Load; STI = Sexually Transmitted Infection; OB/GYN = Obstetrician/Gynecologist.

Time period: In the past 12 months, unless otherwise noted. All measures are self-reported unless otherwise noted.

Bold = significant at p < 0.05 level.

Weighted row percentage.

Based on medical record abstraction data in the past 12 months prior to interview.

^ Chi-square p-value based on the Rao-Scott chi-square.

* Sustained viral suppression is defined as all viral loads in the last 12 months undetectable or <200 copies/ml.

**Hispanics can be of any race/ethnicity.
