Three definitions of sarcopenia: Sarcopenia_BMI = ASM (kg) / BMI (kg/m2) was defined as < 0.789 in men or < 0.512 in women, according to the FNIH recommendation using ASM/BMI ratio; Sarcopenia_weight = ASM (kg) / weight (%) was defined as < 29.0 in men or < 22.9 in women, according to the 2008–2011 KNHANES data; Sarcopenia_height = ASM (kg) / height2 was defined as 7.0 kg/m2 in men or < 5.4 mg/m2 in women, according to the AWGS recommendation using height-adjusted skeletal muscle mass.
The RNI recommended grams per kilogram of body weight is 0.91 g/kg/d.
Multivariable logistic regression model adjusted for age (year), weight (kg), sex, education level, employment status, smoking status, and drinking status.
ASM, appendicular skeletal muscle mass; AWGS, Asian Working Group for Sarcopenia; BMI, body mass index; CI, confidence interval; EER, estimated energy requirements; FNIH, Foundation for the National Institutes of Health; OR, odds ratio; RNI, recommended nutrient intake; TB, tuberculosis.
