A growing body of research has highlighted the possible effects of depression, PTSD, and hostility on aging and telomere length (TL), a cellular aging marker. Individuals who exhibit excessive responses to stressors show notable circulating inflammatory responses with high cortisol reactivity, which increases cell turnover and oxidative stress and may subsequently contribute to shortened TL. This review focuses on the most recent discoveries in the relationship between TL and depression, PTSD and/or hostility, particularly in a unique military population (US active service members during the Afghanistan and Iraq wars). Current findings indicate that there is a solid association between leucocyte TL (LTL) and psychological conditions, such as depression, PTSD, and hostility. Future work should include controlled studies to test these associations. SN - 2638-1311 UR - https://doi.org/10.21926/obm.geriatr.1901041 DO - 10.21926/obm.geriatr.1901041 ID - Hu2019 ER -
