Unlike cross-sectional studies, which are often used to determine prevalence, cohort studies are used to study incidence, causes, and prognosis. A cohort study is a particular form of longitudinal study that samples a cohort (a group of people who share a defining characteristic, typically those who experienced a common event in a selected period, such as birth or graduation), performing a cross-section at intervals through time. This cross-sectional study utilized baseline data from the Transitions Clinic Network (TCN, www.transitionsclinic.org), a multi-site prospective longitudinal cohort study of post-incarceration medical care.
