Abstract

ObjectiveLosing a spouse is a distressing life event that can negatively affect both mental and physical health. Stress-induced health consequences often include increased risk of cardiovascular disease and altered immune system functioning marked by increased inflammation. Here, we sought to identify individual difference factors that covary with problematic inflammatory outcomes.MethodWe measured recently bereaved spouses’ (n = 99) propensity to use emotion regulation strategies and peripheral inflammation, as measured by levels of proinflammatory cytokines after ex vivo stimulation of peripheral leukocytes with T-cell agonists. Specifically, we measured participants’ use of cognitive reappraisal, an adaptive emotion regulation strategy in many contexts, and expressive suppression, a less adaptive emotion regulation strategy that involves actively inhibiting emotions after already experiencing them.ResultsBereaved spouses who self-reported frequently using expressive suppression as an emotion regulation strategy tended to have a more pronounced inflammatory response, as indexed by higher levels of a composite cytokine index consisting of interleukin (IL) 17A, IL-2, IL-6, tumor necrosis factor α, and interferon-γ (b = 0.042), as well as tumor necrosis factor α (b = 0.083) and interferon-γ (b = 0.098) when analyzed individually. Notably, these associations were observed in both unadjusted and adjusted models, with the latter including known covariates of inflammation and other potential confounding variables.ConclusionsThese findings suggest that bereaved spouses’ use of emotion regulation strategies is associated with altered immune functioning, and such a link may be an important biological pathway by which interventions targeting affect may improve immune system–related health outcomes.
