Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

In this study, investigators plan to evaluate the cardiometabolic effects of initiating gender-affirming hormone therapy among transgender women with and without HIV. As part of this study, participants will undergo cardiovascular and metabolic phenotyping within 3 months of starting and after 12 months of gender-affirming hormone therapy. Cardiovascular phenotyping will include cardiac MRI/MRS imaging to evaluate cardiac function and structure. Metabolic phenotyping will include oral glucose tolerance testing, abdominal MR imaging to evaluate visceral adiposity, and whole body, lumbar, and hip DEXA imaging to evaluate fat and lean body mass as well as bone mineral density, respectively. Traditional markers of CVD risk as well as immune, hormonal, and coagulation parameters will also be assessed longitudinally.
