Die soziale Unterstützung von Kindheitstexponien bis hin zur Einbeziehung der Gemeinschaft in Erwachsenen kann die biologische Alterung verlangsamen, die „epigenetischen Uhren“ zurückführen und Sie laut DNA -Studien jünger als Ihre Jahre machen.

> The cumulative effect of social advantages across a lifetime – from parental warmth in childhood to friendship, community engagement and religious support in adulthood – may slow the biological processes of aging itself. These social advantages appear to set back “epigenetic clocks” such that a person’s biological age, as measured by analyzing DNA methylation patterns, is younger than their chronological age.

> The research, which appeared in the October issue of the journal Brain, Behavior and Immunity – Health, drew on data from more than 2,100 adults in the long-running Midlife in the United States (MIDUS) study.

>“Cumulative social advantage is really about the depth and breadth of your social connections over a lifetime,” Ong said. “We looked at four key areas: the warmth and support you received from your parents growing up, how connected you feel to your community and neighborhood, your involvement in religious or faith-based communities, and the ongoing emotional support from friends and family.“

>The researchers hypothesized that sustained social advantage becomes reflected in core regulatory systems linked to aging, including epigenetic, inflammatory and neuroendocrine pathways. And indeed, they found that higher social advantage was linked to lower levels of interleukin-6, a pro-inflammatory molecule implicated in heart disease, diabetes and neurodegeneration. But interestingly, there were no significant associations with short-term stress markers like cortisol or catecholamines.

>his perspective draws on cumulative advantage theory, which holds that resources, whether economic or social, tend to accrue, widening disparities across the life course. This underscores a sobering reality: Access to these social resources is not evenly distributed. Race, class and educational attainment shape the likelihood of growing up with supportive parents, finding belonging in community institutions or having friends and partners who provide steady support.

>That means those already disadvantaged in material ways may also be biologically disadvantaged by a relative lack of sustained social support, potentially accelerating the processes of aging and illness.
