Objective: To understand the epidemiology characteristics of child injury aged 6-17. Data was from the National Injury Surveillance System (NISS) and the results of the study would provide corresponding intervention strategies and decision-making for child injury prevention. Methods: Descriptive analysis was applied to depict the general information, injury event and clinical characteristics of child injury aged 6-17 from 2015 to 2018. Results: A total of 331 663 child injury cases aged 6-17 were reported, with the male and female ratio appeared as 2.19∶1. 15:00-18:59 was the peak time of injury cases from 2015 to 2018. The majority of the injuries occurred unintentional(94.85%). The top three causes of injury cases were falling(51.38%), blunt injury (12.50%)and road traffic injury(11.27%). The injuries occurred mainly at home(28.23%), in schools/public places (27.70%) and on the road/street(20.35%). The main activities were leisure activities (46.67%) and sports activities(14.36%). 49.06% cases were bruise. 31.18% of the injury involved with head, but 83.32% of injuries were minor, while 90.05% left hospital after the treatment. Conclusion Falls, blunt injury and road traffic injury are the key causes of children aged 6-17 to go to the outpatient /emergency department for treatment. Prevention and control should be carried out according to the epidemic characteristics of injuries among children of different genders and ages.

Objective:To investigate the incidence of injuries among children aged 0-17 years from 28 counties in six provinces.Methods:According to the earlier study on data in different local areas and the current work plan, we selected the survey objects for a general survey on child injury prevalence in the last 12 months. The subjects included guardians of children who did not attend kindergartens, children from kindergartens, and primary school grades 1-3. Children from grades 4-6 primary school, junior high school, and senior high school were also included.Results:The overall rate of injured children was 4.83%, with the incidence of injuries as 5.75% in the last 12 months before the survey. Both the rate of injured children and incidence of injuries were higher in boys than that in girls. Children whose primary caregivers were relatives, grandparents, minors, or with an education level below the primary school had a relatively higher rate of both injured children and incidence of injuries. The first cause of child injury was fall. The time of child injury was mainly from June to October, mainly at home, with the main activity as playing. The significant injuries in children were contusion and abrasion, and the main parts injured were lower limbs, upper limbs, and head. Most of the injuries were cured, and the primary treatment was outpatient and emergency treatment.Conclusions:Boys and children whose parents can not take care of are the priority population for child injury prevention and control. Targeted prevention and control measures should be implemented according to the characteristics of injuries among children of different ages.

Objective:To understand the epidemiological characteristic and influencing factors of animal injuries among children from 28 counties/districts in 6 provinces of China to provide evidence for formulating related prevention measures and strategies.Methods:Data was obtained from 'Children injury prevention project, 2016-2020'. Variables on the characteristics, including incidence, locations, related activities, time, and outcomes among children, were described. The negative binomial regression model analyzed animal injury frequency influencing factors.Results:There were 107 029 boys and 97 599 girls, with a gender ratio of 1.10, among the 204 628 children aged 0-17 in 28 counties/districts in 6 provinces of China. Per-person and per-time incidence rates of animal injuries were 0.70% and 0.72%, both higher in boys than in girls. Animal injuries among children mainly occurred in home (73.20%), road/street (7.51%), and open space of community/village (6.77%), during playing (63.15%), with the peak time between 12:01-18:00 (45.03%). Upper limbs (47.89%), lower limbs (35.31%), and head (8.44%) were the most injured body parts. Outpatient or emergency treatment (85.19%) had been carried out. The negative binomial regression showed that sex, grade, guardian educational level, urban or rural, and daily communication between guardians and children as influencing factors in the frequency of animal injuries among children.Conclusions:Special attention should be given to boys, at home, in projects on animal injury prevention and control. There were many influencing factors of animal injury frequency. Knowledge of injury prevention should be popularized to children and guardians. Related comprehensive intervention should be developed in families, schools, and social settings.

Objective:To investigate the incidence of traffic injuries among children aged 0-17 years in 28 counties of 6 provinces and to provide prevention suggestions.Methods:Using the general survey method, a questionnaire survey was conducted on the road traffic injuries of children in 28 counties of 6 provinces in 2017.Results:A total of 204 628 students were surveyed, 908 of whom had experiences of road traffic injuries. Road traffic injuries were 0.44% among children in 28 counties of 6 provinces in China and 0.94% among children who did not attend kindergartens. July is a high incidence period of road traffic injuries among children (12.92%). When children suffer from road traffic injuries, the first three activities were playing (21.61%), riding an electric bicycle (20.40%), walking (20.07%). Most injuries appeared as contusion/abrasion, accounting for 42.26% of the total cases. The injured parts were mainly lower limbs, upper limbs, and heads, accounting for 38.85%, 23.29%, and 20.20%. Most children with road traffic injuries recovered after related treatments, accounting for 85.43% of all cases. The median length of hospital stay of children with road traffic injuries was seven days, and the median expense in hospitals was 3 000 Yuan (RMB).Conclusions:The incidence of road traffic injuries among males appeared higher than females, and the children who did not attend the kindergartens were the highest. During playing, riding an electric bicycle and walking were the top three activities prone to road traffic injuries.
