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

Objectives: To examine the effects of interaction between dynapenic component of the European Working Group on Sarcopenia in Older People (EWGSOP) sarcopenia and obesity (dynapenia x obesity) on activities of daily living (ADL) in older participants. Design: 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. Setting: Six welfare facilities operated by government in South Korea. Participants: Four hundred eighty-seven community-dwelling individuals (157 males, 330 females) >65 years of age. Measurement: 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.
