Introduction: The significance of sarcopenia and low muscle mass are especially emphasized in these days. Sarcopenia is well known to highly correlate with fragility and increases the risk of falling in the elderly and an important risk factor for disability and mortality. Evidence of inter-relaionship of muscle with bone metabolism is increasing. Therefore we investigated the relationship between BMD and muscle mass among healthy Korean premenopausal women.
Materials and methods: A total of 2,711 premenopausal women who taken DXA from 2012 and 2013 in department of health promotion center of our hospital were analyzed retrospectively using demographic data including BMI, WC, HC, waist hip ratio (WHR), muscle mass, fat mass, and lipid profile (total cholesterol, HDL, LDL, TG). Inbody measurement was used to determine fat mass and muscle mass. The Pearson's correlation coefficient (CC) was used to identify coefficiency between Z-score (BMD-L(L1-L4) and BMD-H(femur -Total) and parameters.
Results: The mean age was 44.2 years and mean BMI was 22.43±2.99(kg/m2), mean fat mass and muscle mass were 18.12±5.54 and 37.17±3.80. WHR was 0.80±0.06. Mean Z-score of BMD-L and BMD-H were 0.17±0.94 and 0.33±1.14. Lipid profile, fat mass, abdominal obesity and WHR did not show significant CC. Muscle mass showed a strong correlation coefficency with BMD-H (CC=0.13, P-value=4.78×10–11).
Conclusions: Skeletal muscle mass is a strong correlation factor in total hip bone density among premenopausal Korean women in her forties. The importance of increasing skeletal muscle mass in young aged women should be emphasized to increase total hip BMD.
