Is anxiety related to premature aging? A new study by researchers at Brigham and Women’s Hospital (BWH) shows that a common form of anxiety, known as phobic anxiety, was associated with shorter telomeres in middle-aged and older women. The study suggests that phobic anxiety is a possible risk factor for accelerated aging.
The study will be electronically published in PLoS ONE.
Telomeres are DNA-protein complexes at the ends of chromosomes. They protect chromosomes from deteriorating and guard the genetic information at the ends of chromosomes during cell division. Telomeres are considered markers of biological or cellular aging. Shortened telomeres have been linked to increased risk of cancers, heart disease, dementia and mortality.
In this large, cross-sectional study, researchers had obtained blood samples from 5,243 women, age 42 to 69 years, who were participants in the Nurses’ Health Study. Using the samples, the researchers analyzed telomere lengths, as well as…
