ObjectivesTo quantify the association of social capital, defined as social relationships and networks, with cognitive health, oral inflammation, and epigenetic aging. MethodsWe used data from the Canadian Longitudinal Study on Aging (CLSA) (n=1,479; ages 45-85 years), categorizing social capital as structural and cognitive capital. Oral inflammation was determined as the presence of gum bleeding. Epigenetic aging was computed as the difference between chronological age and DNA methylation age. Multivariable regression models adjusted for covariates were used. ResultsHigher structural social capital was associated with decelerated epigenetic aging and better cognitive health outcomes. Higher cognitive social capital was also associated with better cognitive outcomes and less oral inflammation. ConclusionEnhancing social capital may contribute to better clinical and biological outcomes around aging.

"Similar papers" are the closest papers from that journal in the model's embedding space. They show what the match is built on, but the ranking comes mostly from a classifier over the whole training set, not from these examples alone.
