ABSTRACT
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.
ABSTRACT
Objective@#To understand the injuries among 16 459 left-behind children from 27 poor rural areas in 12 provinces of China, 2016.@*Methods@#Data were collected from the survey of 'Health Service Needs Assessment’ (HSNA) program on left-behind children, from poor rural areas in the middle and western parts of China. Factors including causes, types, locations, related activities, ways of treatment and outcomes among left-behind children with injuries in 2016, were described and analyzed by gender and age groups.@*Results@#In 2016, per-person and person-time incidence rates of injuries were 8.88% and 11.21%, among the 16 459 left-behind children from 27 poor rural areas in 12 provinces of China, both higher in boys, than in girls. Most injuries were unintentional with its proportion higher in older children. The main types of injuries were seen as falls, blunt and sharp injuries, with burns and animal injuries more common in younger children. Injuries among left-behind children mainly took place at home, kindergarten/school, and on the highways/streets/roads, during playing. Most common ways of treatment would include at the emergency settings, self-treated, with older children more likely to treat by themselves. Most injuries were cured.@*Conclusions@#In programs on prevention and control of injuries targeting the left-behind children in poor rural areas, special attention should be given to older boys, on falls and blunt/sharp injuries, at home or kindergarten/school. Education programs should pinpoint on self-rescue skills and guidance on kids by the parents, with behavioral norms and social support included. Related comprehensive prevention and control mechanism should be developed in families, schools and communities, with medical resources and insurance mechanism explored to serve these population and districts, including those left-behind children.
ABSTRACT
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.
ABSTRACT
Injury is an important public health problem that threatening children’s health. Researches have been carried out to prevent child injuries in China. Disease burden on injury for children have been moderated, but remained as the first cause of death in Chinese children, so injury prevention among children should still be treated as priority to promote children’s health. It is necessary to establish and improve strategies in injury prevention which should be led by the government and correlated institutes, as to carry out a systematic, comprehensive and scientific system for children injury prevention and control. In order to reduce children’s injuries and promote children’s health, relevant policies and regulations should base on "Healthy China 2030" to formulate and implement action plans, to carry out practice and scientific research on children injury prevention, and to strengthen the team construction and talent training on this issue.
ABSTRACT
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.

ABSTRACT
Objective@#To understand the status and trend of the mortality rate of falls in different gender, age groups and provinces in China from 1990 to 2015, to explore the number of subgroups of different trends in all provinces, and to determine the different trajectory of subgroups.@*Methods@#Using the mortality rate of falls in China from 1990 to 2015 from the Global Disease Burden 2015 (data covers 31 provinces, autonomous regions, municipalities, as well as Hong Kong and Macau Special Administrative Regions, excluding Taiwan Province) to describe the status of the mortality rate of falls in different gender, age group and provinces in China 2015 and to calculate the corresponding relative change. Using log linear model to calculate the annual percent changes from 1990 to 2015. The number of subgroups and corresponding characteristics of different trajectories were analyzed by trajectory model to analyze with four indicators, P value of the coefficient of independent variables with different orders in all subgroups, Bayesian information criterion, log Bayes factor and average posterior probability.@*Results@#In 2015, the age standardized mortality rate of falls in China was 8.38/100 000 (95%UI: 5.54/100 000-9.30/100 000), which was higher in men (10.81/100 000, 95%UI: 6.58/100 000-12.14/100 000) than that in women (5.84/100 000,95%UI: 3.41/100 000-6.62/100 000), and in the elderly aged 70-year-old and above (60.50/100 000, 95%UI: 38.36/100 000-67.75/100 000) than that in other age groups. From 1990 to 2015, there was no obvious change in the age standardized mortality rate of falls in total population, men and women with average percent change about 0.37 (95%UI: -0.08-0.83), 0.45 (95%UI: 0.05-0.84) and 0.31 (95%UI: -0.26-0.87) respectively, but a significant decrease and increase could be seen in children under 15-year-old, especially under 5-year-old with average percent change about -4.07 (95%UI: -5.62--2.51), and the elderly aged 70-year-old and above with average percent change about 1.89 (95%UI: 1.42-2.37) respectively. Four types of trajectories could be categorized for different trends of age standardized mortality rate of falls in all provinces. The first group had the lowest fall mortality with a downward trend. The fall mortality was close in the second and third group but with different change tendency, a decreasing propensity in the former and an increasing one in the latter. The fourth group had the highest fall morality with obvious fluctuation.@*Conclusion@#There was no significant change in the age standardized mortality rate of falls in China from 1990 to 2015. However, the trend of age standardized mortality rate of falls varied in different age and provinces during the same period of time.
ABSTRACT
Objective To analyze the disease burden of injuries in Chinese children aged between 0-14-year-old,in 1990 and 2013.Methods Data derived from the Global Burden of Disease 2013 was used to analyze the disease burden of injuries among children aged between 0-14-year-old in each province of China,using relevant indicators including mortality and the rate on disability-adjusted life years (DALY).Results In 2013,the number of deaths,rates on mortality and DALY caused by injuries in children aged between 0-14-year-old were 73 766,29.46 per 100 000 and 2 449.36 per 100 000,respectively.Each indicator of injury burden appeared higher in boys than that in girls.With the increase of age,burden caused by injuries in each age group showed a decreasing trend.Provinces and autonomous regions as Xinjiang,Tibet,Gansu,Qinghai and Ningxia ranked the top 5 regions on both mortality rate and DALY rate among children aged between 0-14-year-old.The top 3 injury-related mortality rates and rate on DALY were drowning,road traffic injury and exposure to mechanic forces,among children.Compared to the disease burden of injuries in the 1990s,all indicators showed decreasing trends in children aged between 0-14-year-old,with girls more than boys,and variations in different age groups.In all areas of China,improvements were seen on intervention programs related to the injury-caused burden among children aged between 0-14-year-old,except for Ningxia,Yunnan and Chongqing.Conclusions During the last two decades,there had been significant improvements in reducing the injury-caused burden among the Chinese children aged between 0-14-year-old.However,injury is still the most important risk on health of children under 4-year-old,with boys in particular.Drowning and road traffic injury were the two leading causes of death in children aged between 1 and 14-year-old.

ABSTRACT
Objective To explore the disease burden of road injuries in China.Methods The results of Global Burden of Disease 2013 including death rate,disability-adjusted of life years (DALY),years of life lost due to premature mortality (YLL),years lived with disability (YLD),were used to describe the burden caused by road injuries in 2013 and the trends from 1990 to 2013,in China.Results In 2013,there were 313 676 deaths caused by traffic accidents in China.Death rate,rates on DALY,YLL and YLD were 22.52 per 100 000,1 076.54 per 100 000,971.21 per 100 000 and 105.34 per 100 000,respectively.Rates on deaths,YLL and YLD appeared higher in males,pedestrians than in females and other types of road travelers.Burden of injuries caused by traffic accidents was seen higher in those aged 15 to 49-year-old.From 1990 to 2013,the overall death rate on road injuries increased by 0.54 per 100 000 in China,with an increase of 2.34 per 100 000 and 0.81 per 100 000,respectively in males and pedestrians.The rates on DALY,YLL and YLD decreased by 164.21 per 100 000,115.06 per 100 000 and 49.06 per 100 000,respectively.Conclusions During the past 20 years,achievements had been made on road injury prevention and control,with the decrease of disease burden caused by road accidents.Males,young adults and pedestrians should be called for more attention to prevent road injuries.
ABSTRACT
Objective To analyze the disease burden of violence in the Chinese population,in 1990 and 2013.Methods Indicators including mortality rate,years of life lost due to premature mortality (YLL),years lived with disability (YLD),and disability-adjusted of life years (DALY)related to violence,were extracted from the Global Burden of Disease 2013 and used to describe the burden of disease caused by violence in the Chinese population.Data related to corresponding parameters on disease burden of violence in 1990 and 2013 were described.Results In 2013,a total of 20 500 people died of violent events,with the death rate as 1.44 per 100 000,in China.DALY caused by violence was 1.08 million person years in 2013.DALY caused by sharp violence was 0.47 million person years,with 0.09 million person years lost due to firearm violence.Disease burden caused by violence appeared higher in males than in females.When comparing with data from the 1990s,reductions were seen by 67.35％ on the standardized death rate of violence,by 68.07％ on the DALY attributable to violence,and by 70.47％ on the standardized DALY rate attributable to violence,respectively,in 2013.Disease burden of violence among young adults and elderly was among the highest.When comparing with data from the 1990,DALY in 2013 decreased among all the age groups except for the 70-year-old showed an increase of 9.36％.The standardized DALY rate in 2013 showed a declining trend in all the age groups,mostly in the 0-4-year-old group.The standardized DALY rates caused by sharp violence or firearm decreased by 75.11％ and 83.20％ in the 0-4-year-old group.Conclusion In recent years,the disease burden caused by violence showed a decreasing trend but appeared higher in males however with the increase of DALY in the eldcr population.
ABSTRACT
Objective To understand the current status and change trend of violence against children in China and provide evidence for the risk factor and intervention priority identifications and intervention strategy development.Methods The data of National Injury Surveillance System (NISS) from 2006 to 2015 were used to analyze the change in outpatient visit due to violence against children,injury cases' demographic characteristics,incidence of injury and clinical outcomes of injury cases.Results A total of 44 319 injury cases caused by violence against children were reported through NISS during this period.The proportion of violence related child injury cases in total child injury cases decreased year by year.In child violence cases reported in 2015,boys accounted for 81.31％,the boy to girl ratio was 2.22 ∶ 1.Violence related injuries caused by blunt strike accounted for 65.69％.The incidences of child violence were low in February and during July-August and 48.87％ of violence related injuries occurred in schools and public places,bruise accounted for 63.52％.The main injured body part caused by child violence was head (51.18％),and most violence caused injuries (82.66％)were mild,while 83.21％ of the injury cases went home after treatment.Conclusions Violence against children should not be ignored.Male students of middle/high schools are at high risk.Schools are the places where violence against children is prone to occur.Health and safety education should be strengthened to prevent the occurrence of campus violence and improve the child' s awareness of self-protection and reduce the incidence of serious violence.
ABSTRACT
Objective To analyze the burden and changes caused by burns among Chinese population,from 1990 to 2013.Methods Using the G20 data and the China national and subnational data from GBD2013,this study deemed to comprehensively show the burden caused by burns and the change from 1990 to 2013,using the indicators of death and DALY.Results In 2013,the standardized mortality of burns in Chinese was 0.88/100 000,with the standardized DALY rate of burn as 30.58/100 000.The ratio of DALY between males and females was 1.85 ∶ 1.Among the G20 countries,China ranked 16 for the standardized DALY rate,according to the top down order.The highest death rate was seen in the age group of 70 and over,followed by age group of 5,which had the highest DALY rate and followed by the 70 or older age group.In different provinces,Guizhou presented the highest DALY rate (50.24/100 000),with Aomen area the lowest (6.16/100 000).From 1990 to 2013,the burden of burn reduced generally.Both the standardized rates on death and DALY reduced by 68.10％ and 76.95％ respectively,more in females than in males.Standardized rates on death and DALY reduced among all the age groups,with the rates of reduction increasing by age.From 1990 to 2013,the DALY rate decreased in all the provinces.Conclusions The burden of burn decreased in Chinese population during 1990-2013.However,the burden of burn among children,elderly and males were still relatively high that called for closer attention.

Objective To analyze the disease burden of violence in the Chinese population,in 1990 and 2013.Methods Indicators including mortality rate,years of life lost due to premature mortality (YLL),years lived with disability (YLD),and disability-adjusted of life years (DALY)related to violence,were extracted from the Global Burden of Disease 2013 and used to describe the burden of disease caused by violence in the Chinese population.Data related to corresponding parameters on disease burden of violence in 1990 and 2013 were described.Results In 2013,a total of 20 500 people died of violent events,with the death rate as 1.44 per 100 000,in China.DALY caused by violence was 1.08 million person years in 2013.DALY caused by sharp violence was 0.47 million person years,with 0.09 million person years lost due to firearm violence.Disease burden caused by violence appeared higher in males than in females.When comparing with data from the 1990s,reductions were seen by 67.35％ on the standardized death rate of violence,by 68.07％ on the DALY attributable to violence,and by 70.47％ on the standardized DALY rate attributable to violence,respectively,in 2013.Disease burden of violence among young adults and elderly was among the highest.When comparing with data from the 1990,DALY in 2013 decreased among all the age groups except for the 70-year-old showed an increase of 9.36％.The standardized DALY rate in 2013 showed a declining trend in all the age groups,mostly in the 0-4-year-old group.The standardized DALY rates caused by sharp violence or firearm decreased by 75.11％ and 83.20％ in the 0-4-year-old group.Conclusion In recent years,the disease burden caused by violence showed a decreasing trend but appeared higher in males however with the increase of DALY in the eldcr population.
ABSTRACT
Objective To understand the current status and change trend of violence against children in China and provide evidence for the risk factor and intervention priority identifications and intervention strategy development.Methods The data of National Injury Surveillance System (NISS) from 2006 to 2015 were used to analyze the change in outpatient visit due to violence against children,injury cases' demographic characteristics,incidence of injury and clinical outcomes of injury cases.Results A total of 44 319 injury cases caused by violence against children were reported through NISS during this period.The proportion of violence related child injury cases in total child injury cases decreased year by year.In child violence cases reported in 2015,boys accounted for 81.31％,the boy to girl ratio was 2.22 ∶ 1.Violence related injuries caused by blunt strike accounted for 65.69％.The incidences of child violence were low in February and during July-August and 48.87％ of violence related injuries occurred in schools and public places,bruise accounted for 63.52％.The main injured body part caused by child violence was head (51.18％),and most violence caused injuries (82.66％)were mild,while 83.21％ of the injury cases went home after treatment.Conclusions Violence against children should not be ignored.Male students of middle/high schools are at high risk.Schools are the places where violence against children is prone to occur.Health and safety education should be strengthened to prevent the occurrence of campus violence and improve the child' s awareness of self-protection and reduce the incidence of serious violence.
