title: Dynapenic abdominal obesity and metabolic risk factors in adults 50 years of age and older.
abstract: OBJECTIVE
  To investigate the additive effect of dynapenia and abdominal obesity on metabolic risk factors in older adults.
  
  
  METHODS
  A total of 3,007 men and women from the National Health and Nutrition Examination Survey (NHANES) study were categorized as follows: (a) non-dynapenic/non-abdominally obese (N-DYN/N-AO), (b) dynapenic/non-abdominally obese (DYN/N-AO), (c) non-dynapenic/abdominally obese (N-DYN/AO), (d) dynapenic/ abdominally obese (DYN/AO) based on waist circumference (WC) and leg muscle strength tertiles. Dependent variables were lipids, glucose, blood pressure, and other chronic conditions.
  
  
  RESULTS
  The DYN/AO group had lower plasma HDL-chol and higher triglyceride and glucose levels than N-DYN/N-AO and DYN/N-AO groups (all p ≤ .01). Higher plasma triglyceride was observed in the DYN/AO group compared with N-DYN/AO group (p ≤ .01). The odds of having metabolic syndrome, cardiovascular diseases, and type II diabetes were higher in DYN/AO compared with DYN/N-AO and N-DYN/N-AO.
  
  
  CONCLUSIONS
  DYN/AO older adults might be at greater risk of metabolic alterations than those displaying dynapenia alone or those with neither abdominal obesity nor dynapenia.
