<h4>Introduction</h4>Although anemia is associated with low muscle strength, hemoglobin has been rarely studied considering ferritin.<h4>Aim</h4>To analyze the association between hemoglobin and grip strength in community-dwelling older adults.<h4>Methods</h4>We used data from a German cohort of adults ≥ 65 years, excluding those with CRP > 10 mg/L or taking iron supplements. The gene discussed is CRP; the disease is anemia (phenotype).
