Incidence of high blood pressure in a group of tannery workers in Brazil

Abstract

The aim of this study was to measure the incidence of high blood pressure (HBP) in a medium-size tannery in Botucatu, São Paulo State, southeast Brazil. A previous study at this tannery showed a high prevalence of arterial hypertension. A positive correlation was found between cumulated work time and arterial pressure. We followed a cohort of workers for seven years. At the end of this period, HBP incidence rate was calculated as 0.0964.year(-1). This was considered high compared to other occupational groups.

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

“…1 In Brazil, about one-third of adult population has blood pressure equal to or greater than 140/90 mm Hg or is being treated for high blood pressure. 2,3 The incidence of hypertension, however, has been infrequently reported in developing countries. In Brazil, there is only one cohort study presenting the incidence of hypertension in tannery workers.…”

“…In Brazil, there is only one cohort study presenting the incidence of hypertension in tannery workers. 3 The baseline evaluation of the participants of this population-based cohort was carried out from 1989 to 1991. 4,5 In total, 1089 individuals were interviewed at home, after obtaining informed consent.…”
