David Snowdon, an Epidemiologist and the founding Nun Study investigator, started the Nun Study at the University of Minnesota, later transferring the study to the University of Kentucky in 1990.

The reason for this is that, unlike cross-sectional studies, in which different individuals with the same characteristics are compared, longitudinal studies track the same people, and so the differences observed in those people are less like ...
