Physical Function Impairment and Frailty in Middle-Aged People Living With Human Immunodeficiency Virus in the REPRIEVE Trial Ancillary Study PREPARE

ABSTRACT

BACKGROUND: People with human immunodeficiency virus (PWH) are at risk for accelerated development of physical function impairment and frailty;both associated with increased risk of falls, hospitalizations, and death. Identifying factors associated with physical function impairment and frailty can help target interventions. METHODS: The REPRIEVE trial enrolled participants 40-75 years of age, receiving stable antiretroviral therapy with CD4+ T-cell count >100 cells/mm3, and with low to moderate cardiovascular disease risk. We conducted a cross-sectional analysis of those concurrently enrolled in the ancillary study PREPARE at enrollment. RESULTS: Among the 266 participants, the median age was 51 years;81% were male, and 45% were black, and 28% had hypertension. Body mass index (BMI;calculated as weight in kilograms divided by height in meters squared) was 25 to <30 in 38% and ≥30 in 30%, 33% had a high waist circumference, 89% were physically inactive, 37% (95% confidence interval, 31%, 43%) had physical function impairment (Short Physical Performance Battery score ≤10), and 6% (4%, 9%) were frail and 42% prefrail. In the adjusted analyses, older age, black race, greater BMI, and physical inactivity were associated with physical function impairment;depression and hypertension were associated with frailty or prefrailty. CONCLUSIONS: Physical function impairment was common among middle-aged PWH;greater BMI and physical inactivity are important modifiable factors that may prevent further decline in physical function with aging.
