Vigorous Intensity Physical Activity and C-Reactive Protein in U.S. Adults

Background: Several studies have revealed inverse associations between physical activity (PA) and C-reactive protein (CRP). However, few studies have examined associations between vigorous intensity PA (VIPA) and CRP using nationally representative samples. Methods: The sample (n=14,461) included adults (≥20 years of age) who participated in the 1999-2006 National Health and Nutrition Examination Survey. Reported VIPA was categorized into none, insufficient (\u3c500 \u3eMET·min·wk-1), and meeting the 2008 Department of Health and Human Services PA recommendation (≥500 MET·min·wk-1). The dependent variable was elevated CRP (
