潍坊市儿童伤害发生及其影响因素的非条件Logistic回归分析

The Logistic Regression Analysis of Risk Factors of Unintentional Injuries among 22 384 Children in Weifang

[目的]探讨潍坊市儿童伤害的现状及其相关因素,为伤害的预防提供科学依据。[方法]2005~2006学年,在潍坊市分层整群抽取部分初中生、小学生进行伤害发生情况调查,并用非条件Logistic回归分析方法筛选儿童伤害的主要危险因素。[结果]调查22 384名中小学生,1学年期间发生伤害1 538人,发生率为6.87%;发生伤害3 288人次,伤害人次发生率为14.69%。1学年中,男生伤害发生率为8.51%,伤害人次发生率为19.04%;女生伤害发生率为5.08%,伤害人次发生率为9.95%（P〈0.01）。非条件Logistic回归分析结果,儿童性别、年龄、居住环境、离校距离、业余活动、父母之间的关系、安全教育是影响儿童伤害发生的因素。[结论]男性、年龄较大、居住在闹市、离校距离较远、业余活动运动量大、父母间关系较差、很少接受安全教育的儿童容易发生伤害。

To explore the status and the correlative cause of injuries among children in Weifang, and to provide the basis for injuries preventive methods. [Methods]In 2005-2006 school-years,a cluster sampling study on the status of injuries was carried out among middle school students and primary school students in Weifang. Non-conditional Logistic Regression Analysis was used to detect the main risk factors of injuries. [Results]During one school-year,the incidence of injuries was 6.87%（ Among 22 384 children,1 538 students were suffered the injuries）,and the person-time incidence of injuries was 14.69% （there were 3 288 person-times injuries happened）. In detail,the incidences of injuries in boys and in girls were 8.51% and 5.08 % in differently,and the person-time incidences of injuries in boys and in girls were 19.04% and 9.95 %, with significant difference between those two. The main factors affecting injuries were age, sex, residing environment, distance between school and home, manner of sports in spare time, relationship between parents, and education of safety. [Conclusion]The older boys,lived in the downtown area which was far from the school, were easily to be suffered injuries, especially those children with less sport in spare time, poorer relationship between those parents, and poorer levels in education of safety.
