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.
本研究调查了 1998 年至 2008 年巴西 20 岁以上人群自我报告的动脉高血压的时间趋势。对 1998 年、2003 年和 2008 年全国家庭抽样调查（PNAD）的高血压患病率数据进行了分析。该分析考虑了抽样复杂性，分别纳入了 1998 年、2003 年和 2008 年的 203419、238591 和 257816 人。按性别、家庭收入、巴西地理区域和居住地（城市与农村）分析高血压的时间趋势，并根据年龄调整了患病率。1998 年、2003 年和 2008 年自我报告的高血压患病率分别为 12.5%、13%和 13.9%，年增长率为 1.07%。增幅最大的是东南部地区（1.41%）、男性（1.82%）和城市地区（1.15%）。研究表明，所有收入阶层和年龄段的自我报告高血压患病率均有所上升。了解高血压的流行情况对于支持预防和控制该问题的活动至关重要，特别是针对更脆弱的亚组人群。
