Objective To provide support of policy decision for building safe communities by analyzing occurrence, epidemiological characteristics, and disease burden of injuries among the residents of Hongkou district in Shanghai.
Methods A total of 25 153 residents from 10 400 families were chosen using two-stage simple random sampling and each resident was in terviewed to report retrospectively on injuries occurred from June 1, 2010 to May 31, 2011. The main contents included gender, date of birth, education level, occupation, cause of injury, time and place of injury occurrence, activity when injury occurred, in jured body part, and type of injury.
Results The crude incidence rate of injury was 3.10%, and 95% confidence interval was 2.79%-3.21%; the standardized incidence rate was 2.50%. The person-time incidence rate of injury was 3.30%; the standardized person-time incidence rate was 2.64%. Top three causes of injury were fall, traffic accident, and burn. Most of injuries occurred at home, streets, and public areas. The major types of injury were superficial injury, dislocation/sprain/strain, and fracture. The average treatment cost for each case was RMB 3 047 Yuan. The incidence rate of injury increased with age (1.45% for 1-14 years of age, 1.54% for 15-44 years of age, 3.18% for 45-65 years of age, and 6.48% for 65 and over years of age). There were gender differences in in cidence rate of injury, 2.33% for males and 3.82% for females. The incidence rate was decreased as the education level rising, 4.47% for illiteracy, 4.59% for primary school, 4.38% for junior middle school, 3.27% for high/technical secondary school, 1.89% for college, and 1.57% for university. The incidence rate of injury was also related with the marital status, 1.30% for unmarried group, 3.15% for married group, and 7.35% for divorced/widowed group.
Conclusion To build safe communities and to reduce the injury incidence due to fall and traffic accident, injury prevention interventions that focus on specific groups (women, the seniors, low level of education, divorced/living alone persons) and specific locations (home, streets, and public areas) should be carried out.
