Summary

Telomere length is a reflection of cumulative oxidative and inflammatory stress throughout the life course, as well as oestrogen exposure. There is evidence that telomere length is associated with lifespan; however, it does not appear to be a better indicator of biological age than chronological age, even though it can be considered a biomarker of ageing. There are studies showing association between leukocyte telomere length and many of the common diseases of ageing, lifestyle factors and socioeconomic status. However, the associations are less marked among older people. Research in the area of manipulation of genetic control of telomerase activity controlling telomere length may have clinical applications in future.
