3,075 adults, 70-79 years of age
Health ABC study, a community-based cohort of 3,075 healthy, well-functioning, men and women aged 70–79 years. Average Telomere Length, as measured by Q-PCR, was assessed to see if those with the shortest ATL have poorer survival, shorter life span, and fewer years of healthy life (YHL). Longer telomere length was associated with more years of healthy living. Longer ATL was positively associated with longer years of healthy life (p = .03). Findings suggest that ATL may be an informative biomarker of healthy aging.
