The nationwide impact of injury-related deaths on average life expectancy in China.

To expand the evidence base to inform future public policy aimed at accident prevention, we investigated the impact of different categories of injury on average life expectancy in China. We used data from the National Death Cause Registration Information System and National Maternity and Children Health Surveillance databases, as well as 2010 population data from the National Bureau of Statistics. We then calculated the average life expectancy of the Chinese population, in addition to life expectancy after eliminating injury-related mortality. The average life expectancy of the Chinese population in 2010 was 74.93 years. After eliminating deaths due to injuries, the fourth leading cause of mortality in China, average life expectancy increased by 1.36 years. When this was broken down by population sub-groups, these gains were 1.76 and 0.79 years in men and women, 0.94 and 1.56 years in urban and rural residents, and 1.11, 1.30, and 1.67 years for residents in the Eastern, Central and Western regions respectively. After eliminating all categories of injury, the average life expectancy of the Chinese population was found to increase by 1.36 years. This figure was higher for males and residents of rural areas and Western China.

[Analysis of road traffic injuries from Chinese National Injury Surveillance System, 2006 - 2008].

OBJECTIVE: To describe the distribution of road traffic injuries through hospital based National Injury Surveillance System(NISS). METHODS: Data of road traffic injuries was descriptively analyzed from Chinese NISS from 2006 to 2008. RESULTS: In 2006 - 2008, road traffic injury was the second leading cause from NISS among attendants in ERs or clinics of the hospitals, with males (64.63%, 64.07%, 64.38%) more than females (35.37%, 35.93%, 35.62%). People aged 30 - 44 (36.04%, 34.82%, 34.28%), 15 - 29 (30.74%, 31.57%, 30.13%), 45 - 64 (20.28%, 20.70%, 22.80%) years were seen more than other age groups. The majority of road traffic injuries were unintentional (98.34%, 99.07%, 99.07%), and mostly injured in head (35.21%, 33.74%, 35.77%) and lower limbs (24.08%, 24.54%, 23.95%) which mainly as bruise (56.47%, 57.92%, 58.89%) and fractures (17.70%, 15.84%, 15.88%). The severities of injuries were mainly minor ones (63.69%, 67.24%, 65.68%), and mostly went home right after treatments (59.43%, 63.76%, 62.80%). CONCLUSION: The distribution of road traffic injuries from NISS kept stable from 2006 to 2008. Young and middle aged men were the focus population for road traffic injuries intervention. Further improvement of NISS, multi-sectional collaboration-based advocacies and education programs as well as the enforcement of road safety law seemed the good practices for road traffic injury prevention.

[Analysis of poisoning cases from Chinese National Injury Surveillance System, 2006 - 2008].

OBJECTIVE: To study the preventive strategies through analyzing the poisoning cases from the National Injury Surveillance System (NISS), from 2006 to 2008. METHODS: Data of poisoning cases was descriptively analyzed from Chinese NISS, from 2006 to 2008. RESULTS: The proportion of poisoning cases to all injuries cases from NISS were 2.57%, 2.48% and 2.52% from 2006 to 2008, which ranked sixth in all the injuries causes. Most people being poisoned had junior middle school education and most of them were agriculture/animal husbandry/fishery/water producers or commercial/service personnel. Most of the poisoning incidents were happened at home, always occurred in leisure time - around 8 PM, every day. The common types of poisoning were alcohol, clinical drugs, pesticide and carbon monoxide. Unintentional injuries were the main causes. Self-harm/suicidal cases in the rural areas were more than in the urban areas, with women more than men. The main type of self-harm/suicide related poisoning cases were through drugs or pesticide. ≥ 65, 15 - 29 and 30 - 44 year-olds were most commonly seen. CONCLUSION: Alcoholism was the primary type of poisoning injuries which is the highest in young adults (15 - 29 years and 30 - 44 years). It's important to promote civilized drinking habits and limit access to alcohol for youth. Self-harm/suicide had close relationship with clinical drugs and pesticide. The key points to prevent pesticide and clinical drugs poisoning were safe storage of pesticides, universal security of pesticide, and the supervision on drug producing and marketing. Children and the elderly were the high risk people for carbon monoxide poisoning. Monitoring and intervention must be strengthened.

[Analysis on the characteristics of injuries from the Chinese National Injury Surveillance System].

OBJECTIVE: To analyze the injury characteristics, using data from the National Injury Surveillance System (NISS), 2006 to 2008, to develop a injury prevention strategy. METHODS: 129 hospitals from 43 surveillance points in NISS were selected according to the DSP sample framework, also considering the capacity of local CDC. RESULTS: Relative information on 1 318 739 cases were analyzed. The number of male cases were more than the females. The top three causes of injuries were as follows: falls (28.02%, 29.36%, 30.12%), traffic-related (23.07%, 21.61%, 21.44%) and blunt injuries (21.46%, 21.17%, 20.59%). The major places where injuries occurred were: road/street (29.80%, 27.73%, 28.37%) and at home (21.51%, 22.80%, 24.02%). Recreation activities (35.63%, 41.93%, 42.13%) and at work (24.43%, 22.60%, 21.44%) were the two major activities when injuries took place. Most injury cases were unintentional (83.81%, 86.32%, 86.71%) and mild (70.42%, 74.79%, 73.90%). Rush hours that caused injuries to happen were between 7 to 10 AM. CONCLUSION: Male injury cases were more than females. Falls, road traffic-related and blunt injuries were the major causes, with most of them were unintentional and minor.

[Distribution of children cases in the Chinese National Injury Surveillance System, 2006 - 2008].

OBJECTIVE: To understand the pattern of children injuries treated in hospitals and to provide evidence for its further prevention and control. METHODS: Data of children cases was descriptively analyzed from the Chinese National Injury Surveillance System (NISS), from 2006 to 2008. RESULTS: The incidence rates of boys were twice (2.22, 2.15, 2.15) higher than girls. About one half (50.74%, 49.75%, 49.75%) of them were 5-14 year of age. The main causes were falls (44.14%, 45.68%, 47.15%), RTIs (15.71%, 14.46%, 13.79%), and blunt force injuries (13.20%, 12.92%, 12.40%). Main locations where the injuries happened were at home (34.96%, 36.86%, 38.84%), school and public places (24.72%, 19.80%, 21.19%), and road/street (21.21%, 19.63%, 19.33%). The major injured body parts were head (34.88%, 35.84%, 37.07%), upper limbs (28.00%, 28.21%, 27.81%) and lower limbs (21.86%, 21.49%, 21.31%). The majority cases were unintentional (93.01%, 92.66%, 90.58%), minor (78.50%, 81.20%, 81.52%) injuries, treated and discharged (82.37%, 85.19%, 84.84%). There were considerable differences in the distributions of causes, locations, injured body parts, and other contexts depending on age. CONCLUSION: The pattern of children's injury would include causes, places and other characteristics treated at hospitals from NISS and was related to the age of the injured child which was quite different from the spectrum of death caused by injury. NISS acts as an important source of information on children's injury in China, and can contribute to the prevention and control program on children's injury.

[Analysis on injuries among the elderly from Chinese Injury Surveillance System, 2006 - 2008].

OBJECTIVE: To describe the distribution of injuries among the elderly through hospital based National Injury Surveillance System (NISS), and to provide basic information for prevention of injury among the elderly. METHODS: Data on injuries among the elderly aged 60 years and above was descriptively analyzed from the Chinese NISS from 2006 to 2008. Using the data of NISS from 2006 to 2008, information was collected on those cases who were diagnosed as injuries for the first-time in the site hospitals. Information included demographic characteristics, features of the injury events, and clinical characteristics of injuries. SPSS 16.0 software was used for data analysis. RESULTS: The leading causes of injuries among the elderly were: falls, road traffic injuries, and blunt injuries, which were in total accounting for more than 70% of all the injuries among the elderly. Most of the injuries occurred at home (46.25%, 44.44%, 46.23%), on the roads (30.95%, 28.51%, 28.61%) and in the public residences (8.89%, 11.57%, 11.25%). Recreation activates (42.14%, 48.09%, 48.59%), housework/study (21.15%, 18.21%, 18.15%) and driving (13.67%, 13.80%, 13.56%) were the three major activities when injuries took place. Most injuries among the elderly were unintentional (91.34%, 92.84%, 93.09%). The leading causes of suicide of the elderly were poisoning and sharp injury. The most common natures of injuries were bruise (36.07%, 38.18%, 38.50%), fractures (25.65%, 22.47%, 23.77%), and sharp/bite/open injuries (17.19%, 18.21%, 17.46%) while the most injured part of bodies were head (26.32%, 25.59%, 25.90%), lower limbs (25.74%, 25.70%, 25.26%) and upper limbs (21.01%, 21.14%, 21.37%). Most of the injuries were minor ones (60.53%, 65.09%, 63.58%), and patients mostly went home after treatment (64.11%, 68.53%, 67.99%). CONCLUSION: According to NISS, the proportion of injuries among the elderly in all injuries kept increasing from 2006 to 2008, while distribution of injuries among the elderly being stable. Falls was the most common injury type for the elderly which also brought along bad outcome. Falls was the priority for injury prevention among the elderly.

[Evaluation on the disability weight of Alzheimer's disease and Parkinson's disease in Beijing].

OBJECTIVE: To formulate the classification criteria of disability weight for Alzheimer's disease (AD) and Parkinson's disease (PD) in China and to evaluate the disability weight of AD and PD in population over 60 years old in Beijing. METHODS: Based on the criteria of Global Burden of Disease (GBD), a seven-grade disability classification was used to develop a new disability classification criteria for AD and PD in terms of Delphi method in China. Using the data from epidemiological survey for AD and PD in Beijing in 1997 and new criteria, mean disability weights of AD and PD in population over 60 years old in Beijing were obtained. RESULTS: The mean disability weights of Alzheimer's disease was 0.40 in population over 60 years old who received treatment in Beijing and 0.52 in those without treatment while the mean disability weights of Parkinson's disease were 0.30 in the patient receiving treatment and 0.23 in those without treatment. CONCLUSION: Difference between the result of this study and the data of GBD study in the mean disability weight for AD and PD was noticed.
