At present injury researches mostly use the secondhand data in our country, such as statistics,medical record,newspapers and periodicals,literatures. A cross-sectional research on injuries among residents can clarify injury occurring frequency,distribuing and cause of specific crowd, collect particular course of injury and the rest without going to hospital make a diagnosis and give treatment. A cross-sectional research with community as unit, pertinency is better and explain danger circumstance and harm of injury more exactly, offering more ample scientific basis for decision-making. Along with the developing of community health serving, community health serving units demand to make corresponding programs and measures based on practical instance, carry through prevention and control, construct the mode of safety community to prevent injury at community level step by step. So, these request us to develop community injury study. This research chooses Nan'ao as investigation area, because its geography location is especial. The country is an island, circumstance correspondingly isolated and steady and population is immobile. There has an only integrative hospital. These are propitious to investigate,note and analyze the data of injury occurring exactly and roundly. We will analyze the injury instance of inpatient in Nan'ao hospital during the past twelve years and combine the result of cross-sectional research and hospital-based injury surveillance. Expatiating epidemiology characteristic of injury and residents hospitalize action in order to provide the scientific basis to know injury instances and use the data for govemment departments and provide the foundation data to research on injury for methodology.

There were 754 person-time of 16 community residents who were injuried during the last year, incidence rate(person-time) is 43.28％. The first three of incidence rate were blunt/sharp object injury, tumble/fall and bum/scald. There were 421 person-time male(55.84％) and 333 person-time female(44.16％). Comparing the male incidence rate with the female, there had statistical significance. The incidence rate of blunt/sharp object injury was the most in the male/female, and the male's was higher than the female's. 64.52％were happened in the crowd of 31～55 years old, 45.50％were happened in the crowd, such as farmer,fisher. Subjects in the age range of 1～15 years,41～55 years and 60 years upwards were most likely to tumble/fall, 47.19％were happened in the preschool children and students.

Comparing the result of research on injuries among residents with the result of injury surveillance in hospital. Different injury types accounted for different proportion and injury degree were different too. Conclusions 1.
