In your textbook, Nickitas (2011) describes two theoretical constructs that attempt to explain the relationship between health and some of the social causes identified as part of our definition of health. The importance of this relationship, according to Nickitas, is that it helps to describe how we develop interventions to improve health outcomes. The two theoretical constructs discussed in your textbook are: Life Course Theory and the Theory of Vulnerability. In this discussion, select one of the theories and apply it to a health promotion concept related to your course project.
