ResultsAmong participants, 66 (17%) did not participate in any physical activity. In multivariate model adjusted for age, compared to those who participated in moderate to vigorous physical activity, women who participated in no physical activity had significantly shorter TL (adjusted coefficient β = −0.22; 95% confidence interval (CI), −0.41 to −0.03; P = .03). Non-white race, lower education and depressive symptoms were associated with lack of self-reported physical activity (P < 0.05 for all) but not TL.ConclusionLack of physical activity is associated with shortened TL, warranting prospective investigation of the potential role of physical activity on cellular aging in breast cancer survivors.
