ABSTRACT
Objective To investigate the epidemiological characteristics and the influencing factors of the unintentional injuries among Wenzhou elementary school children. Methods A total of 3 050 students were selected from the 1st to 6th grades in 6 primary schools in Wenzhou urban area by multi - stage sampling and were investigated during 2013 to 2015. Results 2 859 students completed the investigation. The morbidity of annual average unintentional injuries was 30. 81%(95% CI:29. 12% - 32. 50% )and the occurrence density was 2. 79. Unintentional injuries occurred mainly at home (37. 69% )and school(32. 39% ),and the most common site of injuries were leg(35. 02% )and hand(33. 79% ). For overall incidence,the slip falling injury(35. 64% )was highest,followed by cut or pierced(33. 40% )and crush injury (25. 08% ). Schoolgirl was a protective factor of the injury of crushed,electrical,traffic accident,bashed,burn , exploded,drown,poisoning and bit(OR ﹤ 1),but was a risk factor of multiple injuries(OR = 1. 323). Age was a risk factor of injury of fallen,crushed,bashed,burn,cut or pierced,exploded and bit(OR ﹥ 1. 1),but was a protective factor of poisoning(OR = 0. 671). compared with the students who walked to school alone,the children who were accompanied by their family member and rode alone to school were protective factors of the traffic accident. Conclusion The incidences of the unintentional injuries of elementary school children were increased with the age,and the boy was easier to be hurt. It was suggested for parents,schools and the government to strengthen healthy education for children at the early age.
