Abstract

Background Sarcopenia is a progressive and systemic skeletal muscle disorder associated with an increased risk of hospitalization and adverse effects on survival. This study aims to investigate the prevalence and related risk factors of sarcopenia in people living with HIV using the revised European Working Group on Sarcopenia in Older People (EWGSOP2) definition. Methods This cross-sectional study comprising 379 patients with confirmed HIV infection evaluated the appendicular skeletal muscle mass by employing the bioelectrical impedance analysis method. Muscle strength and functional mobility were analyzed using the five-time sit-to-stand test and the timed “Up and Go” test. Results The prevalence rates of pre-sarcopenia and sarcopenia among people living with HIV were 3.4 % and 2.1 % according to the revised EWGSOP2 definition. Advanced age (Odds Ratio 1.07, p = .03), lower body mass index (Odds Ratio 0.79, p = .012) and CD4+ T-cell count below 500/μl (Odds Ratio 2.22, p = .007) were identified as significant factors associated with sarcopenia. Sarcopenia was also identified as a significant correlate of frailty ( p < .001). Conclusion This is the first study examining the prevalence of sarcopenia in people living with HIV according to the revised EWGSOP2 clinical algorithm. Advanced age, lower body mass index and a poor immune status are determined as promoting factors of sarcopenia. Sarcopenia significantly correlates with frailty. Standardized clinical algorithms are essential for reliable sarcopenia diagnosis in people living with HIV in order to promote intervention strategies and to prevent adverse health outcomes.
