Abstract | PURPOSE: The purpose of this study was to examine the association of objectively measured lifestyle light-intensity physical activity (LLPA) and moderate-to-vigorous physical activity (MVPA) with various biological markers and chronic diseases among a nationally representative sample of U.S. older adults (65+ years). DESIGN: A cross-sectional design was used for this study. SETTING: Data were obtained from the National Health and Nutrition Examination Survey (NHANES) 2003-2006. SUBJECTS: Subjects were 1,496 older U.S. adults. MEASURES: Participants wore an accelerometer for at least 4 days and completed questionnaires to assess sociodemographics and chronic disease information. Blood samples were taken to assess biological markers. ANALYSIS: Adjusted Wald tests and Poisson regression were used to examine the association of LLPA and MVPA with biological markers and chronic disease. RESULTS: Older adults engaging in ≥300 min/wk of LLPA had lower observed values for body mass index, waist circumference, C-reactive protein, and insulin resistance compared to those engaging in <300 min/wk of LLPA. Additionally, those engaging in <300 min/wk of LLPA had a rate 1.18 times greater for having chronic disease compared to those engaging in ≥300 min/wk of LLPA. CONCLUSION: In this national sample of older U.S. adults, participation in at least 300 min/wk of LLPA was associated with more favorable health outcomes. Future experimental studies are warranted to confirm these findings. |
