We estimated age-specific and sex-specific incidence rates of intentional injuries (assaults or suicide attempts) occurring between 1979 and 1982 in a population of 87,022 Massachusetts children and adolescents under 20 years of age in 14 communities with populations of 100,000 or less. The average annual incidence of intentional injuries treated at a hospital was estimated to be 76.2 per 10,000 person-years. Overall, 1 in 130 children was treated each year for an intentional injury. More than 85 percent of the injuries resulted from assaults, such as fights, rape, and child battering; 11.4 percent were self-inflicted. Intentional injuries were most common among adolescents. Each year, 1 in 42 teenage boys was treated for an assault-related injury, and 1 in 303 teenage girls was seen for a suicide attempt. Repeated episodes of intentional injury were identified in 4.3 percent of the children. In this population, intentional injuries accounted for 3.4 percent of all injuries but 9.8 percent of hospital admissions and 15.7 percent of deaths from injury. The rate of intentional injury was directly correlated with both the degree of urbanization and the poverty level of the community of residence. We conclude that intentional injuries are relatively common in this population and that attempts to prevent them must be directed to the children who are at greatest risk.
我们估算了1979年至1982年间，马萨诸塞州14个居民人数在10万及以下社区中，87,022名20岁以下儿童及青少年故意伤害（袭击或自杀未遂）的特定年龄和性别的发病率。据估计，医院收治的故意伤害的年平均发病率为每10,000人年76.2例。总体而言，每年每130名儿童中就有1名因故意伤害接受治疗。超过85%的伤害是由袭击导致的，如打架、强奸和虐待儿童；11.4%是自我伤害。故意伤害在青少年中最为常见。每年，每42名青少年男性中有1名因与袭击相关的伤害接受治疗，每303名青少年女性中有1名因自杀未遂接受治疗。4.3%的儿童存在反复故意伤害事件。在这一人群中，故意伤害占所有伤害的3.4%，但占住院治疗的9.8%以及伤害死亡的15.7%。故意伤害率与城市化程度和居住社区的贫困水平直接相关。我们得出结论，故意伤害在这一人群中相对常见，预防故意伤害的努力必须针对风险最大的儿童。
