Years of Age and Older

Objectives: To investigate the additive effect of dynapenia and abdominal obe-sity on metabolic risk factors in older adults. Method: 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 triglycer-ide 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. Conclusion: DYN/AO older adults might be at greater at PENNSYLVANIA STATE UNIV on May 10, 2016jah.sagepub.comDownloaded from 2 Journal of Aging and Health XX(X) risk of metabolic alterations than those displaying dynapenia alone or those with neither abdominal obesity nor dynapenia
