title: Relationships between sarcopenia and household status and locomotive syndrome in a community-dwelling elderly women in Japan.
abstract: OBJECTIVE
  The aim of the present study was to identify factors associated with sarcopenia in community-dwelling elderly women in Japan.
  
  
  METHODS
  A total of 186 women aged over 65 years attending preventive care classes were enrolled in the study. Muscle mass was assessed using bioelectrical impedance analysis. Sarcopenia was defined as low muscle mass and low muscle strength in accord with the consensus report of the Asian Working Group for Sarcopenia. Data regarding household status (living alone, with a spouse, or with children and/or grandchildren), calf circumference and the presence of locomotive syndrome were obtained, as well as dietary variety score, Tokyo Metropolitan Institute of Gerontology Index of Competence and Mini-Nutritional Assessment short form, and 10-item Eating Assessment Tool scores.
  
  
  RESULTS
  Sarcopenia was identified in 21.0% of participants. Participants with sarcopenia were older, had a lower body mass index and calf circumference, and were more likely to have locomotive syndrome, and living with children and/or grandchildren. In multivariate analysis, age, body mass index <18.5 and locomotive syndrome were significantly associated with sarcopenia, as were associated living alone (OR 1.69, 95% CI 0.45-6.41), and living with children and/or grandchildren (OR 2.46, 95% CI 0.71-8.54) and dietary variety score ≥9 (OR 4.98, 95% CI 0.97-25.56).
  
  
  CONCLUSIONS
  Age, body mass index, dietary variety score, locomotive syndrome and household status were associated with sarcopenia. Early interventions are required for older adults identified as having a higher risk of sarcopenia to prevent its adverse health consequences. Geriatr Gerontol Int 2017; 17: 54-60.
