Anthropometric And Body Composition Measurements Related To Osteoporosis In Geriatric Population

Body mass index is calculated as a ratio of height and weight, expressed as kg/m2

waist circumference is measured as cm

hip circumference is measured as cm

height is measured as cm

Fat percentage and skeletal muscle mass (SMM) was calculated by using bioimpedance analysis (BIA) (Tanita TBF 300; Tanita Corp., Tokyo, Japan).

Skeletal muscle index (SMI) was calculated from BIA-based skeletal muscle mass with a formula as SMM/height \[m2\].

ABSI is measured as waist circumference (m) / (BMI(kg)2/3x Height(m)5/6)

Osteoporosis is diagnosed with DXA scores. According to the T-scores calculated from femur neck (FN) and lumbar spine (LS), subjects divided into 3 groups as following: a) normal: T-score is greater than -1 SD (standard deviation), b) osteopenia: T-score is between -1 and -2.5 SD, c) osteoporosis: T-score is lower than -2.5 SD.

Physical activity levels of patients were evaluated with The Rapid Assessment of Physical Activity (RAPA) aerobic assessment. Patients divided into 5 groups as following: 1 = sedentary, 2 = underactive, 3 = regular underactive (light activities), 4 = regular underactive, and 5 = regular active).
