Discrimination may speed up the biological processes of aging, according to a new study led by researchers at the NYU School of Global Public Health .
To better understand the connection between discrimination and aging, Cuevas and his colleagues looked at three measures of DNA methylation, a marker that can be used to assess the biological impacts of stress and the aging process. Blood samples and surveys were collected from nearly 2,000 U.S. adults as part of the Midlife in the United States study, a longitudinal analysis of health and well-being funded by the National Institute on Aging.
A deeper analysis showed that two health factors -- smoking and body mass index -- explained roughly half of the association between discrimination and aging, suggesting that other stress responses to discrimination, such as increased cortisol and poor sleep, are contributing to accelerated aging. "These findings underscore the importance of addressing all forms of discrimination to support healthy aging and promote health equity," added Cuevas.

How biological aging clocks tick | ScienceDailyAging clocks can measure the biological age of humans with high precision. Biological age can be influenced by environmental factors such as smoking or diet, thus deviating from the chronological age that is calculated using the date of birth. The precision of these aging clocks suggests that the aging process follows a program.
