Overview
- Researchers analyzed data from more than 2,100 adults in the U.S. MIDUS cohort and published the findings in Brain, Behavior & Immunity – Health.
- Greater cumulative social advantage across the life course was associated with slower biological aging on epigenetic clocks DunedinPACE and GrimAge.
- Participants with richer, sustained social ties also showed lower levels of IL-6, an inflammation marker tied to risks such as heart disease, neurodegeneration, and diabetes.
- The study evaluated social resources across four domains: parental warmth in childhood, neighborhood and community connection, religious involvement, and ongoing emotional support from family and friends.
- Authors emphasize the results show associations rather than cause, aligning with proposed epigenetic and inflammatory pathways linking social life to health.
