Cross-sectional studyResearch

A study that measures exposure and outcome in a group at one single point in time.

A cross-sectional study samples a population and records exposure and outcome variables simultaneously, at a single time point, without following participants forward. It can estimate prevalence and detect associations, but because exposure and outcome are captured together it cannot establish temporal sequence or causation. Findings are also vulnerable to survivorship and selection bias depending on how the sample was drawn.
