The aim of this study was to describe suicide time trends in Brazil from 1980 to 2005. The data were obtained from the National Mortality Information System and the Brazilian Institute of Geography and Statistics (IBGE). Suicides rates were calculated for the entire period for the country as a whole and the 26 States and Federal District. Annual increases or decreases in mortality rates were also estimated using Prais-Winsten generalized linear regression. The mean suicide rate was 4.12 per 100,000 inhabitants (6.45/100,000 in men and 1.80/100,000 in women). The study showed an increasing suicide trend in men (+1.41% per year, 95%CI: 1.00;1.23) and a decreasing trend in women (-0.53% per year, 95%CI: -0.04;-1.02). Suicide rates increased with age. In general, for all age groups and for both genders, the highest rates were in São Paulo and in the States of the South and Central-West regions.
本研究旨在描述 1980 年至 2005 年巴西的自杀时间趋势。数据来自国家死亡信息系统和巴西地理与统计研究所（IBGE）。计算了全国和 26 个州和联邦区的自杀率。还使用普赖斯-温斯坦广义线性回归估计了死亡率的年增长率或下降率。平均自杀率为每 10 万人 4.12 人（男性为每 10 万人 6.45 人，女性为每 10 万人 1.80 人）。研究表明，男性的自杀趋势呈上升趋势（每年增加 1.41%，95%CI：1.00；1.23），而女性的自杀趋势呈下降趋势（每年减少 0.53%，95%CI：-0.04；-1.02）。自杀率随年龄增长而增加。一般来说，对于所有年龄组和性别，圣保罗州以及南部和中西部地区各州的自杀率最高。
