To investigate injury-related mortality in South Africa using a nationally representative sample and compare the results with previous estimates.
We conducted a retrospective descriptive study of medico-legal postmortem investigation data from mortuaries using a multistage random sample, stratified by urban and non-urban areas and mortuary size. We calculated age-specific and age-standardized mortality rates for external causes of death.
Postmortem reports revealed 52,493 injury-related deaths in 2009 (95% confidence interval, CI: 46,930-58,057). Almost half (25,499) were intentionally inflicted. Age-standardized mortality rates per 100,000 population were as follows: all injuries: 109.0 (95% CI: 97.1-121.0); homicide 38.4 (95% CI: 33.8-43.0; suicide 13.4 (95% CI: 11.6-15.2) and road-traffic injury 36.1 (95% CI: 30.9-41.3). Using postmortem reports, we found more than three times as many deaths from homicide and road-traffic injury than had been recorded by vital registration for this period. The homicide rate was similar to the estimate for South Africa from a global analysis, but road-traffic and suicide rates were almost fourfold higher.
This is the first nationally representative sample of injury-related mortality in South Africa. It provides more accurate estimates and cause-specific profiles that are not available from other sources.
利用具有全国代表性的样本调查南非与伤害相关的死亡率，并将结果与先前的估计值进行比较。
我们使用多阶段随机抽样方法，对来自太平间的法医尸检调查数据进行了回顾性描述性研究，抽样按城市和非城市地区以及太平间规模进行分层。我们计算了各类外部死因的年龄别死亡率和年龄标准化死亡率。
尸检报告显示，2009年有52493例与伤害相关的死亡（95%置信区间，CI：46930 - 58057）。其中近一半（25499例）是故意造成的。每10万人口的年龄标准化死亡率如下：所有伤害：109.0（95%CI：97.1 - 121.0）；凶杀38.4（95%CI：33.8 - 43.0）；自杀13.4（95%CI：11.6 - 15.2）；道路交通伤害36.1（95%CI：30.9 - 41.3）。通过尸检报告，我们发现凶杀和道路交通伤害导致的死亡人数比该时期生命登记记录的多三倍以上。凶杀率与全球分析中对南非的估计相似，但道路交通伤害和自杀率几乎高出四倍。
这是南非首个具有全国代表性的与伤害相关死亡率样本。它提供了更准确的估计值和其他来源无法获得的特定病因概况。
