[Study on the relationship between childhood non-intentional injury and socio-economic status in Jiangxi province].

Objective: To understand the relationship between childhood non-intentional injury and socio-economic status (SES) in Jiangxi province.

Methods: Nearly 100 000 households were selected by PPS sampling method, in Jiangxi province. All children aged 0 - 17 years in selected households were surveyed using an 'injury questionnaire'. SES was calculated under the World Bank method.

Results: 98 335 children were surveyed and the identified number of non-intentional injury cases was 5429 and with 52 fatal cases. The morbidity was 5.52% and mortality was 52.88/100 000. The mortality of children with higher SES was lower than that of other groups but without statistical significance. The morbidity of moderate injury increased with the increasing SES, also without statistical significance. However, the morbidity of severe injury in male children decreased with the increasing SES. Rates of moderate injury morbidities of fall and road traffic injury also increased with the increasing SES. Moderate injury morbidity caused by animals decreased with the increasing SES. Severe injury morbidity of fall decreased with the increasing SES.

Conclusion: The morbidity of injury in children was affected by the SES and the relationship between injury and SES varied along with the results of different types of injuries.
