This conceptual framework in public health distinguishes between how social and biological factors interact to cause individual health outcomes and how they work in tandem to generate patterns. As a result, the public health conceptual framework addresses the social and biological links. It accomplishes this by using concepts such as public health vectors, the life course, and the lifeworld. The vectors outlined in the conceptual framework make a causal approach possible. Empirically, the vectors are not distinct but rather part of a set of forces that overlap and interact. Analyzing them separately, however, is possible.
