Chinese suicide rates have been reported in various studies in the past two decades, but few of them were based on national data. The most recent mortality data (2002-2011) provided by the China Ministry of Health and the detailed census data provided by the National Population Census were used in this study. We calculated the age-, gender-, and region-specific suicide rates and their trends in the past 10 years between 2002 and 2011. The overall suicide rates in China decreased during the study period. The rural/urban ratio of the suicide rates has been significantly reduced from the ratio in the 1990s, and male suicide rates have exceeded those of females. Age was positively associated with suicide rates without the two peaks found in the suicide rates over 20 years ago. The Chinese suicide rates have significantly declined in the past decade, with withering of the unique suicide rate patterns previously found in Chinese suicides about 20 years ago.
在过去二十年的各项研究中都报道过中国的自杀率，但其中基于全国数据的研究较少。本研究使用了中国卫生部提供的最新死亡率数据（2002 - 2011年）以及全国人口普查提供的详细普查数据。我们计算了2002年至2011年过去10年间按年龄、性别和地区划分的自杀率及其趋势。在研究期间，中国的总体自杀率有所下降。自杀率的农村/城市比率已从20世纪90年代的比率显著降低，男性自杀率超过了女性。年龄与自杀率呈正相关，且没有出现二十多年前自杀率中发现的两个高峰。在过去十年中，中国的自杀率显著下降，二十年前中国自杀中曾出现的独特自杀率模式正在消失。
