Abstract: ObjectiveTo understand the incidence of accidental injury and influencing factors in Tibet Autonomous Region and provide evidence for injury intervention.MethodsThe incidence data of accidental injury reported by the surveillance sentinels in Tibet during 2016–2017 were statistically described and analyzed.ResultsDuring 2016–2017, a total of 7 807 cases of accidental injury were reported in Tibet. More cases occurred in males than in females. The age of the cases ranged from 15 year to 44 years. The first five injury causes were fall (30.84%), motor vehicle accident (22.47%), animal bite (20.01%), non-motor vehicle accident (7.52%) and blunt strike (7.28%). The proportions of injuries caused by motor vehicle accident (χ2＝5.374, P＝0.020) and animal bite (χ2＝13.453, P＜0.001) were higher in women than in men, and the proportions of injuries caused by blunt strike (χ2＝19.499, P＜0.001) and knife/sharp instrument cut (χ2＝23.043, P＜0.001) were higher in men than in women, the differences were significant . The first five places where injuries occurred were road/street (36.44%), home (19.41%), public place of residence (14.05%), industrial and construction site (9.47%), school and public place (6.57%); The injury cases in males mainly occurred in industrial and construction sites, and the injury cases in women mainly occurred in trade and service places. The cases in age group 0 year and 60 years mainly occurred at home, and the case in other age groups mainly occurred on road /street. The main related activities were work (1 755 cases, 22.48%), recreational activity (1 446 cases, 18.52%), driving (1 256 cases, 16.09%), walking (1 105 cases, 14.15%).ConclusionDuring 2016–2017, the incidence of accidental injury was high in Tibet. The high-risk group was 15−44 year old men. The high risk causes were fall, motor vehicle accident and so on. The high-risk place was road/street. Targeted injury intervention should be carried out for different groups to effectively reduce the incidence of accidental injury.
