This article describes the characteristics of violence-related injury (VRI) cases presenting at emergency departments (EDs) in Brazil and compares circumstances for assault-related and self-inflicted cases.
The study is cross-sectional. The data describe cases seen in September 2006 in 62 EDs, representing all 26 states and the Federal District. A total of 4 835 case records were analyzed. Basic statistical tabulations were complemented by logistic regression analysis to assess potential associations between type of violence (assault or self-harm) and multiple factors.
Males comprised 72.8% of cases while those aged 20 to 29 comprised 35.4%. Alcohol use was reported or suspected in 42.7% of cases, more commonly among males. Assault victims comprised 91.4% of cases versus self-inflicted injuries, which accounted for 8.6%. Three-fourths of the assault victims were male, while over half of the self-inflicted injury victims were female. The leading mechanism for assaults was physical force/blunt objects (46.2%), whereas poisoning was the predominant mechanism for self-inflicted injuries (71.4%). Younger females were significantly more likely to have been victims of self-inflicted injuries than younger males, while younger males were more likely to have been victims of assault; this finding is more pronounced in cases where alcohol use was reported. Self-inflicted injuries were significantly more likely to occur in residences, while assaults were more likely to occur away from home.
These results can improve understanding of the scope and characteristics of VRIs in Brazil (and thus contribute to national injury prevention efforts), and help identify areas for future research.
本文描述了巴西急诊科出现的暴力相关伤害（VRI）病例的特征，并比较了袭击相关病例和自我伤害病例的情况。
本研究为横断面研究。数据描述了2006年9月在62个急诊科所见的病例，这些急诊科代表了巴西所有26个州和联邦区。共分析了4835份病例记录。基本统计表格通过逻辑回归分析进行补充，以评估暴力类型（袭击或自我伤害）与多种因素之间的潜在关联。
病例中男性占72.8%，年龄在20至29岁之间的占35.4%。42.7%的病例报告或怀疑有酒精使用情况，在男性中更为常见。袭击受害者占病例的91.4%，而自我伤害占8.6%。四分之三的袭击受害者为男性，而超过一半的自我伤害受害者为女性。袭击的主要致伤方式是体力/钝器（46.2%），而中毒是自我伤害的主要致伤方式（71.4%）。年轻女性比年轻男性更有可能成为自我伤害的受害者，而年轻男性更有可能成为袭击的受害者；在报告有酒精使用情况的病例中，这一发现更为明显。自我伤害在住所发生的可能性显著更高，而袭击在离家较远的地方发生的可能性更高。
这些结果可以增进对巴西暴力相关伤害的范围和特征的了解（从而有助于国家的伤害预防工作），并有助于确定未来研究的领域。
