Evidence to support including lifestyle light-intensity recommendations in physical activity guidelines for older adults.

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.
