Abstract

Objectives: To determine the independent effect of long‐term physical activity ( PA ) and the combined effects of long‐term PA and weight loss ( WL ) on inflammation in overweight and obese older adults. Design: Eighteen‐month randomized, controlled trial. Setting: The community infrastructure of cooperative extension centers. Participants: Overweight and obese (body mass index >28.0 kg/m 2 ) community‐dwelling men and women aged 60 to 79 at risk for cardiovascular disease ( CVD ). Intervention: Physical activity + weight loss (PA + WL) (n = 98), PA only (n = 97), or successful aging ( SA ) health education (n = 93) intervention. Measurements: Biomarkers of inflammation (adiponectin, leptin, high‐sensitivity interleukin (hs IL )‐6, IL ‐6s R , IL ‐8, and soluble tumor necrosis factor receptor 1) were measured at baseline and 6 and 18 months. Results: After adjustment for baseline biomarker, wave, sex, and visit, leptin and hsIL‐6 showed a significant intervention effect. Specifically, leptin was significantly lower in the PA + WL group (21.3 ng/mL, 95% confidence interval ( CI ) = 19.7–22.9 ng/mL) than in the PA (29.3 ng/mL, 95% CI = 26.9–31.8 ng/mL) or SA (30.3 ng/mL, 95% CI = 27.9–32.8 ng/mL) group (both P < .001), and hs IL ‐6 was significantly lower in the PA + WL group (2.1 pg/mL, 95% CI = 1.9–2.3 pg/mL) than in the PA (2.5 pg/mL, 95% CI = 2.3–2.7 pg/mL) or SA (2.4 pg/mL, 95% CI = 2.2–2.6 pg/mL) group ( P = .02). Conclusion: Addition of dietary‐induced WL to PA reduced leptin and hs IL ‐6 more than PA alone and more than a SA intervention in older adults at risk for CVD . Results suggest that WL , rather than increased PA , is the lifestyle factor primarily responsible for improvement in the inflammatory profile.

  • The addition of weight loss of 0.3 kg per week for 6 months to physical activity in older community-dwelling adults with obesity or overweight results in a greater reduction in serum levels of leptin and IL-6 than either physical activity alone or a successful ageing health education intervention.

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.
