Determine what type of observational study is described. Explain.

Researchers wanted to determine whether there was an association between city driving and stomach ulcers. They selected a sample of 900 young adults and followed them for a twenty-year period. At the start of the study none of the participants was suffering from a stomach ulcer. Each person kept track of the number of hours per week they spent driving in city traffic. At the end of the study each participant underwent tests to determine whether they were suffering from a stomach ulcer.  The researchers analyzed the results to determine whether there was an association between city driving and stomach ulcers.
◦ cohort; Individuals are observed over a long period of time.
