Telomere length, which declines with age, has been hypothesized to act as an indicator of biological aging. If it fulfills this purpose, shorter telomere length should correlate with age-related loss of physical function, independent of age. In this cross-sectional Australian population study, the associations between peripheral blood leukocyte telomere length and age-sensitive indicators of physical function (lung function, blood pressure, and grip strength) were examined in two narrow age range cohorts aged 44-49 years (n = 351) and 64-70 years (n = 295). Telomere length was correlated with systolic blood pressure but only for women of the younger cohort and in the opposite direction to that expected (partial r = .181, p = .017). This evidence does not provide support for the hypothesis that telomere length is related to age-associated changes in physical function.
