Neighborhood disadvantage is associated with biological aging: Intervention-induced enhancement of couple functioning confers resilience.

ABSTRACT: The accelerated pace of biological aging predicts mortality and morbidity later in life. The current study examines whether a change in supportive couple functioning buffers accelerated aging associated with stressful community environments among Black Americans who live in rural, Southern, disadvantaged neighborhoods.
