Summary

Serum levels of inflammatory mediators increase with age and are strongly associated with the most common and the most devastating health conditions found in older adults including frailty, chronic disease, disability and increased mortality. Even though the processes that contribute to increased inflammatory mediators are likely not completely reversible in older adults, the development of a safe and effective intervention that modulates inappropriate inflammatory responses could be a very important component of prevention against frailty and other adverse health outcomes. As part of an ongoing effort to identify molecular and physiologic triggers of inflammation in older adults, the investigators recently identified a highly significant inverse relationship between the anti-oxidant micronutrient selenium and the inflammatory mediator IL-6, as well as a significant relationship between selenium and all cause mortality in a population of community dwelling older women with selenium levels well below the mean for the overall American population. Based on our findings in older adults and on data from other studies that suggest that selenium interventions are effective in targeted populations with inflammatory conditions, the investigators hypothesize that selenium supplementation targeted to a population of older adults with increased inflammatory markers and low normal selenium levels will in the short term reduce inflammation as measured by serum IL-6, and in the long term will reduce the incidence and prevalence of inflammation associated poor health outcomes of frailty, disability, and mortality in vulnerable older adults.
