The role of gender and age in fracture distribution following the 2008 Wenchuan earthquake

This study explored demographic variations among victims injured in the 2008 Wenchuan earthquake. The study analyzed records of 2,148 patients who were hospitalized with earthquake-related injuries in 14 hospitals between May 12 and May 21 of 2008. We tested the effects of gender and age on the incidence of fractures and amputations. Although more women than men were hospitalized as earthquake victims, the results indicated that a higher incidence of pelvic fracture in women was the only statistically significant injury with regard to gender. Age had a more complex effect on the rate and pattern of fractures. Children younger than 15 years old were the most likely to sustain skull fractures and amputations. The elderly were the most likely to be associated with limb fractures. Adult men were the most likely to suffer spine fractures and adult women rib fractures. The paper concludes with an interpretation of the results in the context of China's rural conditions and discusses implications for post-disaster emergency operations and planning.
