Objective To understand the epidemiologic characteristics of fall in people of 18 years old and below in Wenzhou, and to provide evidence for the development of prevention and control measures of fall in young population. Methods Data of fall in people of 18 years old and below from six sentinel hospitals in Wenzhou during 2018-2019 were collected through Zhejiang chronic disease surveillance and management system for the descriptive epidemiologic analysis. Results Totally 1 073 cases of fall were reported in people aged 18 years old and below during 2018-2019, accounting for 31.71% of total injury cases. The male/female ratio of fall cases was 1.87. Distribution of injuries varied in different sex and age groups, exhibited a statistically significant difference(χ2=9.790, P<0.05). The age at which children fall frequently was 6-12, 0-5 and 13-15 years old. Falls mainly occurred in March to May and September to November. Most fall injuries took place in schools and at home, accounting for 85.65%. The top two activities when falls could occur were recreation activities (41.57%) and sports activities (36.44%). The common injury sites were lower limbs (36.07%), head (35.69%) and upper limbs (24.79%). Children aged 5 years old and below were more likely to experience head injuries. The fall injuries were mainly mild (59.55%). Accordingly, the cases of fall mainly returned home after treatment (96.64% ). Conclusion Falling has become the second cause of children injury in Wenzhou. We should carry out appropriate interventions based on the distribution of children of different gender and age.
