A study with 4452 disability-free adults aged ≥65 years investigating disability in sarcopenia (mean follow-up 30 months) found that compared to non-sarcopenia, individuals with sarcopenia or low serum albumin alone had an increased risk of disability (Hazard ratio (HR): 2.74, 95% CI: 1.58–4.77, and HR: 1.71, 95% CI: 1.26–2.33, respectively), which was further increased in the groups that had both sarcopenia and low serum albumin (HR: 3.73, 95% CI: 1.87–7.44) [16]. This evidence concerns the gene ALB and sarcopenia.
