ABSTRACT
OBJECTIVE: To study the associations of pedestrian injuries with age, income and educational level in Shanghai and to analyze the relative disease burden. METHODS: Information on pedestrian-related cases and deaths were collected from 494 hospitals and mortality registry systems from 1992 to 2010, and a multistage cluster sampling survey conducted in 2006. Logistic regression model was used in the analyses. RESULTS: The age group of 5-9 had the highest mortality and morbidity among children. Mortality increased obviously among those aged 60 or above. Individuals with an educational level under the primary school and with the lower family average income were more likely to suffer pedestrian-related injuries. Multivariate Logistic analysis demonstrated that lower income and lower educational level increased the risk of pedestrian injuries with the odds ratio of 1.40 (95% CI: 1.15-1.71) and 1.70 (95% CI: 1.20-2-40), respectively. About 13.54% of the share of GDP for the healthcare, social security and welfare industries in Shanghai was occupied by the burden of pedestrian-related injuries in 2006. CONCLUSION: Pedestrian-related injury has inverse association with victims' income and educational level. Children of 5-9 years old and adults over 60 with lower educational level and lower monthly income are the target persons to be intervened.

OBJECTIVE: To study age and educational level and their relationship with fall-related injuries in Shanghai and to analyze the relevant costs. METHODS: Multistage cluster sampling was used for the selection of participants and standardized questionnaires were used for the information collection in 2006. Information on cases and deaths caused by fall-related injuries were obtained from 494 hospitals as well as from the mortality registry systems from 2001 till 2010. RESULTS: Of 45 857 participates, 674 suffered from fall-related injuries with the largest proportion among all injuries. The fall-related mortality increased from 10.63 per 100 000 in 2001 to 14.11 per 100 000 in 2010. The under-five mortality rate was the highest among children aged 0-14 years. Mortality increased dramatically among those aged 55 or above for the female and aged 60 or older for the male. Individuals with an educational level under the primary school were more likely to suffer fall-related injuries, accounting for 72.66% of all deaths and 49.24% of nonfatal cases respectively. The annual burden of fall-related injuries equated to 25.90% of the share of GDP for the healthcare, social security and welfare industries in 2006. CONCLUSION: Fall-related injuries were inversely related to victims' educational level. Children under the age of 5, women over 55 years old and men over 60 years old with an educational level lower than the primary school are the most risky groups of populations for intervention measures.

China is known as the Bicycle Kingdom, but the nature, extent, and costs of bicycle-related injuries remain largely unknown. The authors' findings showed that the bicycle-related mortality rate increased 99% from 1992 to 2004, and it increased with age, from 0.64 per 100,000 population in the 0-14 age group to 5.93 per 100,000 population in the 65 and older age group. Labor force groups represented the majority of fatalities (70.8%) and nonfatal injuries (81.5%). The male mortality rate was 2.4 times higher than the female mortality rate. Head injuries accounted for 71.9% of fatalities and 33.1% of the hospitalizations. People with lower levels of education had higher injury rates. The poorer districts located in the countryside had the highest mortality rates compared to those located in the central, wealthier regions. The total annual cost of bicycle-related injuries was 1.1 billion CHY (Chinese Yuan) (over $137 million U.S.). To reduce bicycle-related injuries, mandatory helmet legislations, environmental modifications, and representative monitoring systems in China are required.
