Abstract

In a cross-sectional study, all in a given population or a random sample from this population define the source population. The disease and its possible determinants are all recorded at a given point in time. This introduces a temporal ambiguity in the possible cause–effect association and for this reason most cross-sectional studies have survey purposes that are only descriptive.
