Objectives To provide epidemiological information on injury death in Guangxi province and to provide theoretic basis for control and corresponding health policies to injury. Methods A population-based descriptive epidemiological study utilizing surveillance data was conducted. Standardised mortality rates were compared between sex and among different age groups for different causes of injury. Results There were 3 954 deaths due to injuries to the population aged 1～89 within a period of 5 years in three major cities in the Guangxi province. The majority of deaths were males (n=2 828, 71.5%), nearly half (n=1 894, 47.9%) were aged 25～49. Motor vehicle and other transport-related injury were the most frequent cause. Drowning among children aged less than 15, particularly among boys, was the major cause of death. Falls among older people aged 70 or above was another important cause of death. Significant increasing trend of injury mortality was observed within the study period. Conclusions Injury is aserious health problem in three cities.
