Abstract In a cross-sectional study the occurrence (prevalence) of the disease under study for the ‘exposed’ is compared with the same occurrence in the non-exposed. The exposure and disease status is examined for the same time period. We do not have data to establish exposure status before the onset of the disease.

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 ...
