The fully adjusted model was adjusted for age, hypertension, dyslipidemia, osteoarthritis, osteoporosis, diabetes mellitus, smoking history, alcohol history, location of residence, family group, number of medications, and the MMSE-KC score
Obesity defined as BMI ≥ 25 kg/m2
PBF percentage of body fat, OR odds ratio, CI confidence interval, HGS hand grip strength, ASMI appendicular skeletal muscle mass index, SPPB short physical performance battery
^aLow HGS, < 28 kg for males and < 18 kg for females; low ASMI, < 7.0 kg/m2 for males and < 5.4 kg/m2 for females; low SPPB, score ≤ 9 for both sexes
^bSarcopenia: low ASMI (< 7.0 kg/m2 for men and < 5.4 kg/m2 for women) and either low HGS (< 28 kg for men and < 18 kg for women) or low physical performance (SPPB score ≤ 9 for both sexes)
