Social Support —few concepts in epidemiology have proven more elusive to define. While the term is used loosely to describe the care and companionship we receive from family and friends, in epidemiology it refers to an abstract construct that has been linked to numerous health outcomes. As a result, social support has received considerable attention in the literature as an important disease prognosticator despite issues with measurement and lack of clear implications for applying this knowledge.
