title: Effect of interaction between dynapenic component of the European working group on sarcopenia in older people sarcopenia criteria and obesity on activities of daily living in the elderly.
abstract: OBJECTIVE
  To examine the effects of interaction between dynapenic component of the European Working Group on Sarcopenia in Older People (EWGSOP) sarcopenia and obesity (dynapenia × obesity) on activities of daily living (ADL) in older participants.
  
  
  METHODS
  Cross-sectional analysis of the Validity and Reliability of Korean Frailty Index and the Validity and Reliability of the Kaigo-Yobo Checklist in Korean Elderly studies.
  
  
  METHODS
  Six welfare facilities operated by government in South Korea.
  
  
  METHODS
  Four hundred eighty-seven community-dwelling individuals (157 males, 330 females) >65 years of age.
  
  
  METHODS
  Dynapenic component of the EWGSOP sarcopenia was defined as usual gait speed <0.8 m/s or grip strength lower than cut-off value (male <25.3 kg, female <12.0 kg). Obesity was defined as body mass index ≥27.5 kg/m(2). ADL were assessed using the Barthel index.
  
  
  RESULTS
  There were 14 obese with dynapenic component cases (2 males, 12 females) of the 487 participants. Interaction of dynapenia and obesity was significant on multivariate generalized linear model analysis (P = .015).
  
  
  CONCLUSIONS
  Dynapenic component of the EWGSOP sarcopenia and obesity in the elderly is associated with multiplicative interactions rather than additive interactions in ADL.
