ABSTRACT

OBJECTIVES: The aim of this study was to examine changes in physical performance and handgrip strength during hospitalization as well as to evaluate their interrelationship with inflammatory and nutritional status. DESIGN: Data were available on 302 elderly patients with a mean age of 80.83±7.14 years. Handgrip strength, gait speed and chair-stand test were assessed at admission and before discharge. In all subjects, serum CRP values and Mini Nutritional Assessment scores were also evaluated. RESULTS: The risk of worsening in chair-stand test performance was 4.2 (95% confidence interval (CI): 1.574-11.310) for subjects with simultaneous presence of malnutrition and CRP⩾50 and 3.3 mg/dl (95% CI: 1.127-9.423) for subjects with CRP⩾50 mg/l not malnourished in comparison with subjects with Mini Nutritional Assessment (MNA)⩾24 and CRP⩽10 mg/l. The risk of handgrip strength loss was 8.8 (95% CI: 3.545-21.662) in subjects with simultaneous presence of malnutrition and CRP⩾50 and 2.9 mg/dl (95% CI: 1.223-6.783) in subjects with CRP⩾50 mg/l not malnourished in comparison with subjects with MNA⩾24 and CRP⩽10 mg/l. CONCLUSIONS: Simultaneous presence of high CRP values and malnutrition determines an additive effect on muscle strength loss and physical performance.
