-A '''longitudinal study''' is a study that involves the repeated observation or examination of the same set of subjects over time with respect to one or more study [[variables]], particularly in [[medical]] research where the subjects are living beings. A longitudinal study is often desired because it follows changes in the same people. In contrast, a [[cross-sectional study]] compares results across different people, which can introduce undesired variables to distort the results.
