Background: Today, global attention has been directed towards differences in the health of different Socioeconomy of society (SES) groups. Trauma is one of the categories where SES determinants are not well understood, especially in developing countries. This study aims to determine the annual incidence of traumabased on SES in people over 15 years old in Kashan.
Methods: This was a population-based cross-sectional studyusing a household survey .Data were collected through stratified-cluster sampling during 2018- 2019 for over 15-year in Kashan. The researchers conducted univariate and multivariate analyses to evaluate trauma during and the past year rgarding SES of individuals using Principal Components Analysis (PCA).
Results: The incidence of trauma was 70.6 (62. 6-78. 7) in 1000 annually, the risk of trauma in low SES was 1.06 (0.82-1.38), in moderate SES , 0.87
(0.69-1.10), and in high SES, it was 1.13 (0.84-1.52). Among different SES groups, mechanisms of injury were different (P-value = 0.09); also, the annual incidence of trauma in different SES groups was different based on the place of trauma (P-value = 0.02), the number of injuries (P-value = 0.00), treatment (P-value = 0.02), and the time to return to work (P-value = 0.00).
Conclusions: Annual incidence of trauma in different SES groups was different based on the place of trauma, the number of injuries, treatment, and time to return to work. The relationship between SES status and incidence of trauma is important to provide preventive services.
