Theories consist of a group of statements, based on careful reasoning and/or evidence that present a systematic and logical view of the health problem. The statements are logically organized to identify, define, and describe the problem and its determinants, and to explain the direct and indirect relationships among the determinants and the problem. The explanations clarify conceptually why and how the relationships come about, that is, what goes on that connects each determinant to the problem.
