RESUMEN
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.
