Epidemiological characteristics and risk factors of nonfatal injury among middle school students in Zhejiang Province / 预防医学

ABSTRACT

Objective@#To understand the epidemiological characteristics of nonfatal injury and its influencing factors among middle school students in Zhejiang Province,and to provide evidence for prevention and control of nonfatal injury of adolescents. @*Methods@#Using multi-stage stratified cluster sampling method,24 157 middle school students from 442 schools in 30 counties（cities,districts）of Zhejiang Province were selected to investigate socio-demographic characteristics,the occurrence of nonfatal injury and injury-related behaviors from April to May of 2017. Logistic regression model was used to analyze influencing factors for nonfatal injury among middle school students.@*Results@#The incidence of nonfatal injuries in 23 462 secondary school students in the past 12 months was 20.86%. The incidence of nonfatal injury was 24.15% in boys,which was higher than 17.33% in girls（P<0.05）. The incidence of nonfatal injury was 20.17% in urban students and 21.19% in rural students,and the difference between them was not statistically significant（P>0.05）. The incidence of nonfatal injury was 22.17% in junior high school students,19.42% in senior high school students and 19.51% in vocational high school students,and there was statistically significant difference between them（P<0.05）. The results of the multivariate logistic regression analysis showed that boys（girls：OR=0.805,95%CI：0.728-0.890）,poor academic performance（OR=1.149,95%CI：1.018-1.298）,smoking（OR=1.260,95%CI：1.083-1.466）,drinking（OR=1.410,95%CI：1.279-1.553）,more physical activity（OR：1.244- 1.527,95%CI：1.098-1.767）,loneliness（OR：1.336-1.500,95%CI：1.219-1.682）,sadness（OR=1.308,95%CI：1.186-1.441）,absenteeism（OR=1.390,95%CI：1.182-1.634）,running away from home（OR=1.242,95%CI：1.076- 1.435）,fighting（OR=1.771,95%CI：1.594-1.967）and being bullied（OR=2.071,95%CI：1.869-2.294）were risk factors for nonfatal injury in middle school students.@*Conclusion@#The incidence of nonfatal injuries among secondary school students was 20.86%. Male students were the high risk group. The incidence of nonfatal injury was related to gender,smoking,drinking,negative emotions and violence.
