The association between haemoglobin concentrations and muscle mass determined from urinary creatinine excretion rate: a population‐based cohort study

Anaemia is highly prevalent in the general population, particularly in the elderly.1-3 Diminished haemoglobin concentrations, a marker of anaemia, are known to strongly impact health-related quality of life, most prominently impairing physical functioning.4, 5 This negative impact on perceived physical functioning is particularly pronounced among older individuals, (i.e. ≥60 years)5. Indeed, previous studies have revealed that low haemoglobin...
