Cardboard floor: about the barriers for social progression and their impact on the representativeness of epidemiological studies.

Abstract

The most disadvantaged extreme of the social continuum is usually underrepresented in epidemiological studies. We discuss the consequences of excluding this segment of the population and suggest different approaches for addressing this issue. In particular, we describe/analyse a barrier that tends to perpetuates people in the most disadvantaged extreme of the social continuum, hereinafter referred to as the “cardboard floor”. Besides, we propose different approaches to accessing to the least favoured, segment in order to study the cardboard floor. The adoption of these strategies could help to visualize this barrier, allowing to better monitoring social mobility and their expected health improvements, as well as increasing the representativity of population health studies.
