西南地区1 340例故意伤害案件的特征及相关因素分析

Analysis of Characteristics and Relevant Factors of 1 340 Cases of Intentional Injury Cases in Southwest China

目的探究我国西南地区故意伤害案件的伤者信息、致伤工具、发生时间等因素的特点及规律。方法随机抽取西南地区多地2014-2016年轻伤二级及以上故意伤害案件1 340例,分类汇总伤者信息、作案动机、致伤工具、发生场所、发生时间、损伤部位和损伤程度,并对作案动机与致伤工具类型,以及损伤程度与致伤工具作关联分析。结果所涉案件中,伤者多为20~50岁青壮年(65.2%)、男性(82.3%)、农村户籍(62.8%);作案动机以纠纷为主(45.8%),致伤工具多为钝器(54.6%)和锐器(36.0%),尤以徒手(36.9%)和刀具(33.2%)多见;案件主要发生在公共场所(59.0%),1月(11.3%)、2月(13.1%)、3月(11.6%)及每天夜晚22:00~01:00(23.2%)是高发时期;损伤主要涉及颅面部,所致损伤程度以轻伤二级(61.6%)为主。不同作案动机中致伤工具的类型差异有统计学意义(P<0.05),不同损伤程度中致伤工具的分布差异有统计学意义(P<0.05)。结论我国西南地区故意伤害案件的发生有潜在的规律和相关影响因素,预防、分析此类案例需从伤者信息、致伤工具、发生时间等多方面综合考虑。

Objective To investigate the characteristics and patterns of factors such as victims’ information, injury tools and time of occurrence of intentional injury cases in southwest China. Methods One thousand three hundred and forty intentional injury cases from several places in southwest China from 2014 to 2016 assessed as minor injury level Ⅱ and above had been randomly selected. Data on victims’ information, motives, injury tools, sites of occurrence, time of occurrence, injured parts and degrees of injury were classified and gathered, and then association analyses of motives and types of injury tools as well as degrees of injury and injury tools were made. Results Most of the victims were young adults between 20-50 years(65.2%), male(82.3%), rural household registration(62.8%);the motives were mainly dispute(45.8%). Injury tools were mostly blunt(54.6%) or sharp(36.0%). Specifically, injuries were mostly made bare-handed(36.9%) and by cutting tools(33.2%);the cases mainly occurred in public areas(59.0%). Cases occurred more frequently in January(11.3%), February(13.1%), March(11.6%) and from 22:00 to 01:00 every night. Injuries mainly involved the craniofacial region. The wounds were mainly assessed as minor injury level Ⅱ(61.6%). There was statistical significance in the difference of types of injury tools among cases with different motives(P<0.05).There was statistical significance in the difference of the distribution of injury tools among cases with different degrees of injury(P<0.05). Conclusion The occurrence of intentional injury cases in southwest China has potential patterns and relevant influencing factors. Prevention and analysis of such cases need to be comprehensively considered from the aspects such as victims’ information, injury tools and time of occurrence.
