The Study Of Injury Epidemiological Characteristics And Its Risk Factors On 1704 Students In A Health School Of Anhui Province

Objective To study the injury epidemiological characteristics and its risk factors in Suzhou City Health School students over the past year,cognition on injury under the influence of two injury events in this school,in order to provide basic evidences for the establishment of effective interventions.Methods Referring to Chinese adolescent health-related behavior questionnaire of high school,the questionnaire survey was conducted for the 1756 students of 25 classes admitted in the early September 2007.Effective response rate was 97.04%.The main contents of the survey include:general condition,cognition on injury,injury type, location,reasons,treatment cost of the injury occurred in the past year,and so on. Statistical analysis involved t test,chi-square test,and Logistic regression analysis.Results For the 1704 students surveyed,632 people have been injured,the incidence of injury was 37.1%.Totally 1093 injury events occured,the injury Density was 64.14%.The injury rate for boys is 54.95%,and for girls is 36.02%.The difference between the sexes was significant(P＜0.002).The average age for the students injury occurred is 16.84 years old,the standard deviation is 1.2 years old,the average age of the other 1072 students that never injured is 16.87 years old,the standard deviation is 1.25 years old(P = 0.6＞0.05),the difference was not significant. The results of the spatial distribution of injury:home,school and elsewhere injury rates were 30.93%,22.71%,10.50%(P＜0.001),the difference was significant,total injury cases occurred at home and at the school were 83.63%,injury cases occurred in other places accounted for only16.37%;injury rates living in the village,downtown ,county or city were 58.69%,74.90%and 68.81%,respectively.There was no significant difference(P= 0.039).The results of time distribution of injury showed that injury rates in spring, summer,autumn and winter were 16.14%,32.22%,10.45%and 5.34%,respectively,the difference was significant(P＜0.001).The results suggested that the injury occurs more in spring and summer.The incidence of common injuries and its spatial distribution of the results:injury rate followed by bumps(17.6%),knife wounds(11.2%),sprains(9.9%),burns(9.6%), hit by a hard object(5.0%).The proportion of various types of injuries at home were knife wounds(27.5%),bumps(21.6%),burns(14.1%);the proportion of the top three injuries at school were bumps(25.9%),sprains(22.4%) and burns(18.9%).Knife wounds occur at home,schools and other places followed by 73.7%,21.1%and 5.2%; sprain in schools accounted for 57.4%;burn in schools accounted for 50%;animal bites and bones in the throat mainly occur at home;vehicle injuries occurred outside of school and home more.The reasons of all types of injuries:bumps and sprains occur mainly in the exercise,such as playing basketball,running,going up and down the stairs and so on; stab wounds were mainly by household chores,such as choring vegetable,fruit;burns mainly took place in the cooking,dining,filling boiled water into thermos;vehicle injury occurred mainly in cycling,walking;fall injuries occur when ccrossing over the houses,the windows of the classrooms and the fence.Single variable logistic regression analysis revealed that the main influential factors included gender,type of family,career of father and mother,reminding times,the object reminded,education of parents,cycling regulations,carrying knives,climbing walls, slapsticks up and down the stairs,crossing the road carelessly,taking wrong medicine or food or the food given by strangers to,taking a taxi driven by the drunk.Multiple variable logistic regression showed that gender,father's occupation,the one who was reminded,the way parents treat their children,crossing over the wall, slapsticks occurred up and down the stairs,misuse of drugs or the toxic food,taking a taxi driven by the drunk were important influential factors.Conclusion After injury prevention health education was taken,the incidence rate of injury is still high.Injury can occur in schools,homes and other places.Home and school are common places for injuries happened.School,family and community must act together and take comprehensive measures to carry out intervention.
