The aim of the study was to determine the relationship between the components of clinical sarcopenia and osteoporosis in postmenopausal women.

A population-based cohort of 590 Finnish postmenopausal women (mean age 67.9; range 65–72) was selected from the Osteoporosis Fracture Prevention (OSTPRE-FPS) study in 2002. Bone mineral density (BMD) and lean tissue mass were assessed by dual X-ray absorptiometry (DXA). The study sample was divided into three categories according to the WHO BMD classification: normal, osteopenia and osteoporosis. The study sample was divided into non-sarcopenic, presarcopenic, sarcopenic and non-classified groups according to quartiles of RSMI i.e. relative skeletal muscle index (appendicular muscle mass (kg)/square of height (m)), hand grip strength (kPa) and walking speed.
