The effects of sarcopenia and obesity on femur neck bone mineral density in elderly Korean men and women.

ABSTRACT:

Objectives

We aimed to clarify the relationship between fat, muscle, and bone in elderly men and women.

Methods

We analyzed 1373 men and 1803 women who were older than 65 years from the 2008-2010 Korea National Health and Nutritional Examination Surveys. Body composition and femur neck bone mineral density (BMD) were measured by dual-energy X-ray absorptiometry. Sarcopenia was defined as an appendicular skeletal muscle index (SMI) below one standard deviation (SD). Obesity was classified by fat mass index (FMI). Osteoporosis was defined as a BMD of 2.5 SD below that of femur neck BMD.

Results

SMI and FMI were positively correlated with femur neck BMD. In multiple regression analysis, SMI (β = 0.302 in men, β = 0.154 in women; p < 0.001 each) and FMI (β = 0.079 in men,
