Incidence of hypertension in Porto Alegre, Brazil: a population-based study

Studies describing the incidence of hypertension in populations, particularly in individuals with pre-hypertension, are uncommon. In this population-based cohort study, we demonstrated that it was 39 cases per 1000 person-years among adults living in a large city in southern Brazil. Four out of five individuals in the age range of 40-49 years with pre-hypertension would have hypertension in 10 years.
