A cohort analysis involving 8334 participants from the Atherosclerosis Risk in Communities Study, who were free of hypertension and coronary heart disease at baseline, showed that higher levels of consumption of all types of alcoholic beverages were associated with higher risk of hypertension for all race-gender strata at six years of follow up.

A cohort study, in other words a prospective study, is a research design which study subjects – disease-free at enrollment and chosen based exposure rank. Unexposed and exposed groups are followed for the same amount of time to determine who develops the disease of interest.

A prospective cohort study is a longitudinal cohort study that follows over time a group of similar individuals who differ with respect to certain factors under study, to determine how these factors affect rates of a certain outcome.
