| ObjectiveAnalyze the situation of unintentional injury of Taiyuan Grade 4-5 children,explore the influence of parental rearing pattern and neural behavior on unintentional injury of the Grade 4-5 children in Taiyuan,providing theoretical basis for the prevention of unintentional injury in children.MethodThis survey adopts the multistage sampling method to select one primary school in 6districts of Taiyuan city and 4 suburban districts,randomly select 3-4 classes in each primary school in the fourth and fifth grade,the total of 2875 students in the selected 10classes were investigated.By questionnaire survey to acquaint with the condition of unintentional injuries for children in the last year.Meanwhile,take the“WHO neural behavioral core test combination”and finish the investigation of parental rearing pattern.By EpiData3.1 set up the database,SPSS22.0 and SAS9.4 were used for statistical description and analysis.Results1.Overall situation of unintentional injury to childrenOf the 2644 subjects,no unintentional injury occurred was 2041 people(77.2%),and unintentional injuries occurred was 603(22.8%).Among 603 children who have unintentional injuries,370 people(61.4%)had once unintentional injury,132 people(21.9%)had two unintentional injuries and 101 persons(16.7%)have had three or more unintentional injuries.2.Comparison of injuries among general demographic characteristics of childrenAfter mann-whitney U test,the number of unintentional injuries of male students was greater than the female students,the number of nonintentional injuries in 4 grade children was greater than children in 5 grade(P<0.05).It can’t be considered that there are differences in unintentional injuries among children with different household registration,whether they are only children or whether their parents are divorced(P>0.05).According to Jonckheere-Terpstra trend test,it could be considered that the number of unintentional injuries have a downward trend with the increase of age(H=-3.118,P=0.002);It was not considered that there was a linear trend between children’s father culture or mother culture and unintentional injury occurrence(P>0.05).3.Parental rearing patternAmong the 2644 children,the parental rearing pattern was specialized was 1061(40.1%),inconsistencies was 192 people(7.3%),coddled was 49 people(1.9%),laissez faire 35(1.3%)and democratic 1307(49.4%).By the chi square test,the difference of parental rearing patterns was statistically significant between different ages(χ~2=32.151,P=0.010),it could be considered that the overall distribution of parental rearing patterns was different between children of different ages.Chi square segmentation test show the parental rearing pattern of 9 years old children is different from the parental rearing pattern of 11 years old children(χ~2=13.773,P=0.010).By Kruskal-Wallis rank test,the number of unintentional injuries of children in different parental rearing patterns was statistically significant(H=11.842,P=0.019).Through all paired comparisons,the number of unintentional injuries in children under the authoritarian parenting model was lower than the children that under democratic and inconsistent parental rearing patterns.The number of unintentional injuries of children in doting parental rearing pattern was lower than that in inconsistent parental rearing pattern(P<0.05).4.Neurobehavioral in childrenBy independent sample t test,the average reaction time of girls was longer than that of boys,the digital span order scores was higher,target tracking error counts are low.The average simple reaction time of children in the 4 grade was longer than that of 5 grade children,the digital span sequence score,reverse digit span score,and the total number of digital spans was low.Rural children are more accurate than urban children in the simple reaction test,and the average reaction time was shorter in simple reactions(P<0.05).Variance analysis results indicate that different age children simple reaction time scoring average response time,order of digit span score,digit span reverse score and total score of digit span population distribution is different(P<0.05).The results of variance analysis showed that the number of correct times and the number of errors in the simple reaction of children with different mother culture were different(P<0.05),mother culture was junior college and above the correct number of children was less than the other children,and the number of children’s mistakes was more than other children.Single factor ordered Logistic regression analysis showed,the number of correct reactions in a simple reaction test(Waldχ~2=7.516,P=0.006),in the digital span test,the order score(Waldχ~2=6.855,P=0.009),reverse score(Waldχ~2=6.812,P=0.009)、total score of digital span(Waldχ~2=10.730,P=0.001)were protective factors for unintentional injury;Single factor ordered Logistic regression analysis showed that the number of erroneous reactions in a simple reaction test(Waldχ~2=7.489,P=0.006)、mean reaction time(Waldχ~2=9.135,P=0.003),target tracking test error points(Waldχ~2=4.798,P=0.028)were risk factors for unintentional injury.5.The interaction between parental rearing patterns and children’s neural behavior on injuryAnalysis of the generalized linear mixing effect model showed that the interaction(F=3.319,P=0.010)between the correct number of children’s simple reactions and parental rearing patterns has an effect on the occurrence of unintentional injury,the interaction between correct number of children and the autocratic parental rearing pattern was the risk factor for unintentional injury(B=0.215,P=0.001),the interaction between average response time and parental rearing patterns in children’s simple response(F=3.656,P=0.006)has an impact on unintentional injury.The interaction between the longer average child response time and the autocratic parental rearing pattern was protective factor for unintentional injury(B=-0.137,P=0.027),the interaction between the reverse scores of children’s digital span and parental rearing patterns(F=2.386,P=0.048)had an effect on the occurrence of unintentional injury,the interaction between the reverse high score of children’s digital span and the parental rearing pattern of the specialized was the risk factor of unintentional injury(B=0.165,P=0.016);The interaction between the total score of children’s digital span and parental rearing patterns(F=2.584,P=0.043)had an effect on unintentional injury,the interaction between the overall score of children’s digital span and the parental rearing pattern of the specialized parents was the risk factor of unintentional injury(B=0.180,P=0.004).Conclusion(1)The incidence of unintentional injuries of Grades 4-5 children in Taiyuan was high,boys and young children are high-risk groups of unintentional injury.(2)In children’s neurobehavioral,the more number of correct responses in simple reaction,the high score of the digital span test sequence,the high reverse order and the total score of the digital span are the protective factors for the unintentional injury of children.The average reaction time is longer in simple reaction and more error points in target tracking are risk factors for children’s unintentional injuries.(3)The interaction of different parental rearing patterns and children’s neurobehavioral characteristics to the occurrence of injury,suggesting that parents should understand the behavioral characteristics of children and adopt appropriate rearing patterns in order to reduce the occurrence of injury. |
