Trends in self-reported arterial hypertension in Brazilian adults: an analysis of data from the Brazilian National Household Sample Survey, 1998-2008.
This study investigated the time trend in self-reported arterial hypertension from 1998 to 2008 in individuals older than 20 years in Brazil. Data were analyzed on prevalence of hypertension from the National Household Sample Survey (PNAD) for the years 1998, 2003, and 2008. The analysis considered the sampling complexity and included 203,419, 238,591, and 257,816 individuals in the years 1998, 2003, and 2008, respectively. The time trend in hypertension was analyzed by sex, family income, geographic regions of Brazil, and area of residence (urban versus rural), and the prevalence rates were adjusted for age. Prevalence of self-reported hypertension was 12.5% in 1998, 13% in 2003, and 13.9% in 2008, with an annual increase of 1.07%. The highest increases occurred in the Southeast Region (1.41%), in men (1.82%), and in urban areas (1.15%). The study showed a rise in the prevalence of self-reported hypertension in all income brackets and with increasing age. Knowledge of the prevalence of hypertension is essential for backing activities to prevent and control the problem, especially among the more vulnerable subgroups.
