目的了解重庆市居民伤害发生状况,为开展伤害预防提供依据。方法采用多阶段随机抽样方法,选取重庆市3个区1 087名居民为调查对象,由经过培训的调查员进行入户调查,了解调查对象的人口学信息、伤害状况。用SAS 8.0软件进行统计学分析,计数资料的比较用χ2检验。结果过去1年内伤害发生率为20.33%,男性人群伤害发生率为21.54%,女性人群伤害发生率为18.99%。不同年龄人群伤害发生率随着年龄的增长而降低,差异有统计学意义(χ2=44.49,P<0.05)。不同职业人群中伤害发生率差异有统计学意义(χ2=30.19,P<0.05),技术工作人员伤害发生率(31.11%)较高。不同性别伤害类型分布差异有统计学意义(χ2=20.63,P<0.05),男性人群因骑摩托车或电动车、体育运动引起的伤害发生率(分别为4.20%、8.93%)明显高于女性人群(分别为1.94%、4.46%),女性人群在家庭生活中烫伤、动物咬伤、触电、碰撞等伤害发生率(14.15%)明显高于男性人群(9.98%)。结论重庆市居民意外伤害发生率较高,应针对伤害危险因素全面系统地实施人群干预措施,提高居民对伤害的预防和自我保护意识,预防控制伤害的发生。
Objective To understand the occurrence of injury among residents in Chongqing and provide the basis for injury prevention. Methods The multi-stage random sampling method was used to select 1,087 residents in 3 districts of Chongqing as survey subjects. The trained investigators carried out household surveys to understand the demographic information and injury status of the surveyed subjects. SAS 8.0 software was used for statistical analysis, count data comparison using χ2 test. Results The incidence of injuries in the past year was 20.33%, the incidence of injuries in males was 21.54%, and the incidence of injuries in females was 18.99%. The incidence of injury at different age groups decreased with age, the difference was statistically significant (χ2 = 44.49, P <0.05). The incidence of injury among different occupational groups was statistically significant (χ2 = 30.19, P <0.05), and the incidence of injury to technical staff was higher (31.11%). There were significant differences in the distribution of injuries among different genders (χ2 = 20.63, P <0.05). The incidence of sports injuries caused by motorcycles was 4.20% and 8.93% respectively in males than in females The incidence of scalds, animal bites, electric shocks and collisions (14.15%) in the female population was significantly higher than that of the male population (9.98%) in the population (1.94% and 4.46% respectively). Conclusion There is a high incidence of accidental injuries among residents in Chongqing. A comprehensive and systematic intervention of population intervention should be carried out according to the risk factors of injury so as to enhance residents’ awareness of injury prevention and self-protection and prevent and control injury.
