In Portugal, the bottom-up participation has been rising in legislation, as a formal representation and giving population an advisory role or approval to decision makers, and the descendant participation is programmatic of 'health promotion' and is addressed to specific population groups. The horizontal participation is present but undeveloped. What is the impact of participation in terms of the presence of a plurality of rationalities about production methods of health?
The (sociology of) participation in health focus only in a secondary way on the field of the conceptualization of what is health and medical rationality that supports the therapeutic view - areas that sociology of health focuses. In this area, participation is of (self) – excluding type, present in the sketched 'movement' around the 'alternative medicine' and its holistic look on the individual.
Our empirical research on lay rationalities of health and disease emphasizes the importance of recognizing cultural subjectivity and its assertion within the system. This is the field of participation related to knowledge (scientific - lay) and represents an extension of knowledge.
