| 目的探讨不同回顾时限对儿奄青少年伤害流行病学调查结果的影响。方法对马鞍山市4523名学生进行1年的伤害主动监测，各学校由校医或健康信息员每天收集学牛伤害事件，监测时间为2007年11月1日至2008年10月31日。监测对象分成3组，每组分别采用不同的间隔时限进行伤害自我回顾性报告。结果4523名学生，全年共发生伤害事件6350人次，总伤害事件年发生率为74．2％，男生发生率(78．6％)高于女生(70．0％)，差异有统计学意义(P<0．01)。问隔3个月一次的网顾性报告伤害年发生率减低0．02％，伤害次数减少19人次；间隔6个月一次的回顾性报告伤害年发生率减低0．02％，伤害次数减少58人次；12个月回顾性调查过去一年内伤害事 件发生情况，伤害年发生率减低8．8％，伤害次数减少505人次，以3～6岁组和轻度及微小伤害减低更为显著。结论间隔3个月一次和间隔6个月一次回顾性报告的伤害年发牛率只有轻微减低，对伤害信息的获得较完整；12个月的回忆期限，低估了伤害的发生风险；儿童青少年伤害的回顾时限以6个月为宜。 |
