Abstract


The purpose of this study was to examine the association between physical activity and CD4+ T cells and various biological markers among those with HIV. Data from the 2003- 2006 National Health and Nutrition Examination Survey were used. Participants were asked to wear an accelerometer for 7 days. A blood sample was used to detect HIV and measure various biological parameters. Nineteen adults between 18 and 48 years of age had HIV and provided sufficient accelerometry data. Physical activity was not associated with CD4+ T cells. After adjustments, moderate-to-vigorous physical activity was inversely associated with systolic blood pressure (r = −0.44), fasting glucose (r = −0.78), and waist circumference (r = −0.45). These findings suggest that HIV-infected individuals are similar to those in the general population in that that their bodies are able to adapt to the many benefits associated with physical activity.
