We evaluated the Veterans Aging Cohort Study (VACS) Index score, an index composed of age, CD4 count, viral load, hemoglobin, Hepatitis C coinfection, Fibrosis Index-4, and estimated glomerular filtration rate, and psychosocial and clinical risk factors for all-cause hospitalization among HIV-infected women on highly active antiretroviral therapy and HIV-uninfected women.


Data were collected from 2008 to 2014 from 1585 highly active antiretroviral therapy-experienced HIV infected and 692 uninfected women. Cox proportional hazards regression evaluated predictors of first hospitalization over 2 years.


Among HIV-infected women, VACS Index score (per 5 points) [adjusted hazard ratio (aHR) 1.08; 95% confidence interval (CI): 1.06 to 1.11], Centers for Epidemiologic Studies-Depression (CESD) scores ≥16 (aHR 1.61; 95% CI: 1.30 to 1.99), smoking (aHR 1.26; 95% CI: 1.02 to 1.55), abuse history (aHR 1.52; 95% CI: 1.20 to 1.93), diabetes (aHR 1.63; 95% CI: 1.31 to 2.04), and black race (aHR 1.28; 95% CI: 1.03 to 1.59) increased risk of hospitalization. Among HIV-uninfected women, VACS Index score (aHR 1.08; 95% CI: 1.03 to 1.13), CESD scores ≥16 (aHR 1.38; 95% CI: 1.02 to 1.86), diabetes (aHR 2.15; 95% CI: 1.57 to 2.95), and black race (aHR 1.61; 95% CI: 1.15 to 2.24) predicted subsequent hospitalization.


Psychosocial and clinical factors were associated with risk of hospitalization independently of the VACS Index score. Additional research on contextual and psychosocial influences on health outcomes among women is needed.
