Disease burden on falls among 0-19 years old population in China, in 1990 and 2017 / 中华流行病学杂志

Objective@#To analyze and compare the disease burden of falls in Chinese population aged 0-19, in 1990 and 2017.@*Methods@#Indicators including number of deaths, mortality rates, years of life lost due to premature mortality (YLL), years lived with disability (YLD) and disability-adjusted of life years (DALY), on falls, were gathered from the Global Burden of Disease (GBD) 2017 and used to describe the disease burden and corresponding parameters on falls, between 1990 and 2017, in China.@*Results@#In 2017, number of death, YLLs, YLDs, DALYs caused by falls were 5 321, 0.43 million person years, 0.14 million person years and 0.57 million person years respectively, among aged 0-19 group. Rates on standardized mortality, YLLs, YLDs and DALYs on falls were 1.76/100 000, 141.49/100 000, 46.99/100 000, and 188.48/100 000, respectively. The burden of falls decreased with the increase of age. Compared with 1990, disease burden of falls decreased in all age groups, both in male and female, with more seen in the lower age groups. Compared with 1990, the number of deaths, rates on YLLs, YLDs and DALYs caused by falls decreased by 65.08%, 46.63%, 47.38% and 36.33% respectively, in 2017. However, the YLDs rate increased by 73.31% between 1990 and 2017. The ratio of YLLs to DALYs decreased from 90.84% in 1990 to 75.07% in 2017, with a proportion as 17.36%.@*Conclusion@#Compared with 1990, although the disease burden of falls among aged 0-19 group showed a decreasing trend, falls still caused serious disease burden for the aged 0-19 group. Research that targeting prevention on falls, should be continued.

Road traffic injury happened on the way to school, among primary and secondary school students in Mengzi city, Honghe prefecture, Yunnan province in 2018 / 中华流行病学杂志

Objective@#To understand the current situation of road traffic injuries among primary and secondary school students in Mengzi city.@*Methods@#Using the cluster random sampling method, more than 9 000 primary and secondary school students from 20 primary and secondary schools in Mengzi city, were randomly sampled. A questionnaire survey was conducted on the occurrence of road traffic injuries in school students.@*Results@#A total of 9 197 students were surveyed, including 150 from road traffic injuries. The incidence rates of road traffic injuries was 1.63% among students in Mengzi city and 2.85% among junior high school students, with the high incidence in May. The leading places of injuries were village roads (38.00%), city roads (33.33%) and district roads (12.67%), respectively. 26.67% of the traffic injuries occurred on the way to or from schools, with riding on electric bicycle (52.00%) as the major cause and contusion/abrasion (75.33%) appeared as the major signs. Both lower and upper limbs plus multiple parts were accounting for 45.51%, 22.16% and 16.17%, respectively of all the injuries. 70.67% of all the cases with road traffic injuries in children, recovered after treatment. Children with road traffic injuries would stay in the hospital for up to 90 days but spent less than 30 000 Yuan.@*Conclusion@#The incidence of road traffic injuries among students in Mengzi city seemed relatively high, with junior high school students reached the highest. Riding electric bicycle appeared as the leading cause for traffic injuries in children in Mengzi city of Yunnan province.

Disease burden of animal injury in China, 1990-2016 / 中华流行病学杂志

Objective: To analyze the disease burden of animal injury in China between 1990 and 2016. Methods: Data obtained from the Global Burden of Disease 2016 were used to analyze the age and gender specific disease burden of animal injury in China, using the incidence and disability adjusted of life years (DALYs) rate. Relative and annual changes were evaluated. Results: In 2016, the age-standardized incidence and DALYs rate of animal injury in China showed as 245.05 per 100 000 people and 12.73 per 100 000. The age-standardized incidence of non-venomous animal injury was significantly higher than that of venomous animal injury, but the differences in age-standardized incidence and DALYs rate between venomous animal injury and non-venomous animal injury were not significant. Between 1990 and 2016, there was a significantly decreasing trend in the age-standardized incidence and DALYs rate of animal injury, and obvious decline could be seen in the incidence of non-venomous animal injury, compared with venomous animal injury. The incidence and DALYs rate of animal injury declined in both males and females and in different age groups. The obvious decline of incidence and DALYs rate could be found in children aged 5-14 years and aged <5 years. Conclusions: Between 1990 and 2016, there was a significant alleviation of the disease burden of animal injury in China. Young children were most prone to animal injury, resulting in serious disability and death, indicating more attention should be paid to this population at high risk and in animal injury prevention and control programs.

The laws and policies about violence injury prevention, related data collection capacity and violence injury prevention programs in China were described.</p><p><b>RESULTS</b>The violence injury mortality declined by 46.3% during 2006-2013 from 1.21/100000 to 0.65/100000. The incidence of violence injury death in males peaked in age group 30-34 years (1.42/100000), and it was low in age group<15 years. Three peaks of violence injury death were found in females, i.e. 0.84/100000 in infants, 0.72/100000 in age group 30-34 years and 1.18/100000 in age group≥85 years.

Analysis on data from Chinese National Injury Surveillance System, 2008-2013 on the characteristics of falls / 中华流行病学杂志

<p><b>OBJECTIVE</b>To analyze the trend and distribution of Falls, using the data from National Injury Surveillance System (NISS), 2008-2013, to provide basic information for Fall prevention.</p><p><b>METHODS</b>Data of Falls was descriptively analyzed from the Chinese NISS from 2008 to 2013.</p><p><b>RESULTS</b>In total, 1 223 905 cases of Falls were analyzed, that accounted for 32.94% of all the injury cases, with the gender ratio as 1.57. Both the number and the proportion of the cases showed an increasing trend. Labor population (15-64 years-old) accounted for 66.63% of the total 271 502 cases of Falls in 2013. Cases aged 0-4, 5-14 and over 65 accounted for 55.53%, 52.93% and 56.59% among all the types of injuries in each of their age group. Gender ratio appeared to be 1.54 but more females cases were seen with the increase of age. The peak hours that injuries took place were 10:00-10:59 AM (10.04% of total) and 14:00-20:59 PM (43.56% of total).
