Abstract

Objectives: To examine the association between physical activity and inflammatory markers, with consideration for body fatness and antioxidant use. Design: Cross‐sectional study, using baseline data from the Health, Aging and Body Composition Study. Setting: Metropolitan areas surrounding Pittsburgh, Pennsylvania, and Memphis, Tennessee. Participants: Black and white, well‐functioning men and women (N=3,075), aged 70 to 79. Measurements: Interviewer‐administered questionnaires of previous‐week household, walking, exercise, and occupational/volunteer physical activities. Analysis of covariance was used to examine the association between activity level and serum C‐reactive protein (CRP), interleukin‐6 (IL‐6), and plasma tumor necrosis factor alpha (TNFα) with covariate adjustment. Antioxidant supplement use (multivitamin, vitamins E or C, beta carotene) was evaluated as an effect modifier of the association. Results: Higher levels of exercise were associated with lower levels of CRP ( P<. 01), IL‐6 ( P<. 001), and TNFα ( P=. 02) (e.g., CRP=1.95 mg/L for no exercise and 1.72 for >180 min/wk). Adjustment for body fatness attenuated the associations somewhat. Use of antioxidant supplements modified the CRP ( P interaction =.01) and IL‐6 ( P interaction =.08) associations such that concentrations were low in those taking supplements (e.g., CRP=1.79–1.84 across exercise levels) and higher in nonsupplement users who did no exercise (2.03) than in those who did the most (1.72). Among nonexercisers, higher levels of other physical activity were related to lower levels of CRP ( P<. 01) and IL‐6 ( P=. 02) but not TNFα ( P=. 36), even after accounting for body fat. Conclusion: Inflammatory markers are lower in older adults with higher levels of exercise and nonexercise activity and in antioxidant supplement users regardless of exercise level.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
