Association between chronic airway diseases and handgrip muscle strength (HGS) and appendicular skeletal muscle index (ASMI)
| Individual components of sarcopenia | Chronic airway diseases | Model 1 | Model 2 | ||
| β (se) | 95% CI | β (se) | 95% CI | ||
| HGS kg# | No (n=3836) | Ref. | Ref. | ||
| Yes (n=1246) | −0.356 (0.203) | −0.753−0.041 | −0.506 (0.199) | −0.898−−0.114 | |
| ASMI kg·m−2 | No (n=3836) | Ref. | Ref. | ||
| Yes (n=1246) | −0.209 (0.029) | −0.265−−0.153 | −0.190 (0.028) | −0.245−−0.136 | |
Ref.: no chronic airway diseases. Model 1 was adjusted for age and sex; model 2 was model 1 plus total body fat (%), height (cm) and smoking status. #: height is only included in the HGS model due to ASMI already being calculated based on height (m2).
