目的 为研究中小学生伤害的流行病学特征、发生原因及为干预措施的建立提供科学依据。方法 １９９８ 年７ 月对广东省江门市９ 所中小学３ ９８８ 名学生进行伤害调查和流行病学特征分析。结果 显示伤害的总发生率为５０ ．５５ ％ ，前五位伤害依次为：跌伤（３２ ．１５ ％ ） 、刀或锐器伤（２１ ．８９％ ）、碰伤（１７ ．０５％ ）、交通伤（１２．５１ ％ ） 、烧烫伤（１１ ．４３ ％ ） 。结论 伤害发生率与年龄、父母文化程度、是否独生子女密切相关，但与性别、父母职业、与亲属一起生活情况无明显关系。预防学生伤害关键在于建立完善的监督管理体系、强化安全卫生教育、提高学生自我保护意识
Objective To study the epidemiological characteristics of primary and secondary school students, their causes and provide a scientific basis for the establishment of intervention measures. Methods In July 1998, 3 988 students from 9 primary and secondary schools in Jiangmen City of Guangdong Province were investigated for their injuries and epidemiological characteristics. The result showed that the total incidence of injuries was 50. 55%. The top five injuries were ascending injury (32.15%), knife or sharp injury (21.89%), bruising (17.05%), traffic injury (12.51%), burning Burns (11.43%). Conclusion The incidence of injuries is not related to age, parental education and whether or not an only child, but not to gender, parental occupation and relatives living together. The key to preventing student injury lies in establishing a sound supervision and management system, strengthening safety and hygiene education and raising students’ self-protection awareness
