Awareness, treatment, and control of hypertension among women at risk or living with HIV in the US South.

Abstract

Timely control of hypertension is vital to prevent comorbidities. We evaluated the association of race/ethnicity and HIV infection with incident hypertension outcomes, including awareness, treatment, and control. We evaluated cisgender women living with HIV and sociodemographically matched women living without HIV recruited into four Southern sites of the Women's Interagency HIV Study (WIHS) (2013-2019). We calculated measurements of the time to four events or censoring: incident hypertension, hypertension awareness, hypertension treatment, and hypertension control. Hazard ratios for race/ethnicity and HIV status were calculated for each outcome using Cox proportional-hazards models adjusted for sociodemographic, behavioral, and clinical risk factors. Among 712 women, 56% were hypertensive at baseline. Forty-five percentage of the remaining women who were normotensive at baseline developed incident hypertension during follow-up. Non-Hispanic white and Hispanic women had faster time to hypertension control compared with non-Hispanic black women ( P = 0.01). In fully adjusted models, women living with HIV who were normotensive at baseline had faster time to treatment compared with normotensive women living without HIV ( P = 0.04). In our study of women in the US South, non-Hispanic black women became aware of their hypertension diagnosis more quickly than non-Hispanic white and Hispanic women but were slower to control their hypertension. Additionally, women living with HIV more quickly treated and controlled their hypertension compared with women living without HIV.
