To determine the morbidity, mortality, and epidemiologic features of pediatric powder-firearm injuries in a defined urban population.
A population-based, descriptive epidemiologic study was conducted of firearm injuries to children in a mid-size urban community (total population: 435,178) in 1992. The population was 56% white and 39% black. Data from prehospital care providers, all city and adjacent community hospitals, and medical examiner and police records were searched for cases of firearm injury. The 1990 United States census provided denominator data.
Subjects were all 0- to 16-year-old residents of Kansas City, Missouri who sought medical treatment at a hospital for a powder-firearm injury or who presented to the medical examiner with a fatal firearm injury in calendar year 1992.
Seventy-two children met the case definition, for an incidence of 70 per 100,000 persons per year. There were 12 (16.7%) fatalities, for a mortality rate of 11.7 per 100,000 persons per year. Almost 10% of the patients sustained permanent disability. Mean and median ages of the patients were 14.9 years and 15.8 years, respectively; 79% were male and 82% were black. The majority of the children (63%) lived in census tracts with a high proportion of families in poverty. Black males had the highest rates of firearm injury, with a 1-year incidence of 233 per 100,000 persons per year. At younger than 12 years, the rates were equal among the races; however, for those 12 years and older, black adolescents had 13 times the risk of white adolescents (541 compared to 42 per 100,000 persons per year). The majority (71%) of injuries were due to assaults, with drive-by shootings the most frequent circumstance. The majority of unintentional injuries occurred to adolescents as the result of an unplanned discharge of a handgun as it was being placed in or removed from concealment. Among the patients, 39% were admitted to the hospital and 26% required surgery.
确定特定城市人群中儿童火药枪伤的发病率、死亡率及流行病学特征。
1992年在一个中等规模城市社区(总人口435,178)对儿童火器伤进行了一项基于人群的描述性流行病学研究。该人群中56%为白人,39%为黑人。检索了院前急救人员、所有城市及相邻社区医院以及法医和警方记录中的火器伤病例。1990年美国人口普查提供了分母数据。
研究对象为1992日历年在密苏里州堪萨斯城因火药枪伤在医院寻求治疗或因火器致命伤被送至法医处的所有0至16岁居民。
72名儿童符合病例定义,年发病率为每10万人70例。有12例(16.7%)死亡,死亡率为每10万人每年11.7例。近10%的患者有永久性残疾。患者的平均年龄和中位数年龄分别为14.9岁和15.8岁;79%为男性,82%为黑人。大多数儿童(63%)生活在贫困家庭比例高的普查区。黑人男性火器伤发生率最高,年发病率为每10万人233例。12岁以下时,各种族发病率相等;然而,12岁及以上者,黑人青少年的风险是白人青少年的13倍(每年每10万人中分别为541例和42例)。大多数伤害(71%)是由于袭击,驾车枪击是最常见的情况。大多数意外伤害发生在青少年身上,是因为手枪在隐藏或取出时意外走火。患者中,39%住院,26%需要手术。
1)黑人男性青少年火器伤或死亡风险最高。2)大多数受害者生活在以贫困为特征的普查区。3)伤害极其严重。4)人际暴力是致命伤和非致命伤的主要原因。5)意外伤害通常发生在武器隐藏过程中。6)伤害和死亡的主要原因是青少年与枪支,尤其是手枪的相互作用。该人群预防火器伤的主要意义在于限制青少年获得枪支的机会。此外,应探索旨在预防暴力行为的措施,如非暴力冲突解决方法的教育。
