Body composition in COPD patients. chronic obstructive pulmonary disease fat free mass index body mass index quality of life correlation
Conditions
Interventions
The BMI was calculated as weight/height squared. Fat-
free mass (FFM) was measured by BIA using the body composition analyzer foot-
foot system (The Tanita SC-
330P,
Corporation of America Inc.,
Arlington Heights
United States). The Tanita BIA system provides a valid measure of percent body fat in older adults,
and could be a convenient and practical approach for assessment in public health settings.
Subjects were measured standing erect with bare feet on the analyzer footpads. FFM was standardized for heigh
offs used for low BMI (≤
18.5 kg/m2) and low FFMI (≤
16 kg/m2 in men and ≤
15 kg/m2 in women).15 Normal or altered body composition were defined in 4 categories
normal body composition: [BMI >18.5 and FFMI 16 (men) or >15 (women)],
semistarvation: [BMI ≤
18.5 and FFMI >16 (men) or >15 (women)],
muscle atrophy/sarcopenia [BMI >18.5 and FFMI ≤
16 (men) or ≤
15 (women)],
