Background and aims: The telomere length of peripheral blood leukocytes has been reported to be inversely correlated with many kinds of pathophysiological conditions. However, correlations between telomere length in peripheral blood leukocytes and patients' physical ability are not known.
Methods: To address this problem, the physical ability of patients with cerebrovascular disease admitted to the chronic disease ward of Kyushu University Hospital was assessed with the Barthel index (BI) and the telomere length of their peripheral blood leukocytes was determined.
Results and conclusions: Women exhibited a significant correlation between the Barthel score and the expression of long telomeres (>9.4 Kb), in contrast with men who revealed no such correlation. The physical ability of older women was positively correlated with the lengths of their somatic telomeres. Among the BI items, the scores of more difficult physical performances tended to correlate with the presence of terminal restriction fragments longer than 9.4 Kb.
