				        	Objective To describe the association between age and the sex-based outcome difference and analyze the potential mechanism responsible for sex-based outcome difference in severe trauma patients.Methods A retrospective analysis derived from the Emergency Intensive Care Unit of the acute trauma center of the Shanghai Municipal Sixth People's Hospital during the 2010-2013 period was performed to identify sex-based outcome differences after severe blunt trauma.The study cohort of patients was then stratified by age:(1) 18 years ≤ age <45 years,(2) 45 years ≤ age ≤ 55 years,and (3) age >55 years.Crude and adjusted odds ratios (ORs) were calculated to evaluate the association between gender and the hospitalized mortality,both overall and subgroups according to age categories.Results A total of 987 severe trauma patients met our inclusion criteria were enrolled in this study.Crude mortality was higher in male severe trauma patients (male 9.1% vs.female 5.0%,P < 0.05).Multiple logistic regression revealed that females had a 79% decrease in hospitalized mortality compared with males (OR =0.21,95% CI:0.07-0.64,P =0.006).This difference was most distinct in patients with age < 45 years,(OR =0.15,95% CI:0.04-0.67,P =0.012).There is no significant difference between genders in mortality of trauma patients with 45 years ≤ age ≤ 55 years and age > 55 years.Conclusions The present study revealed a statistical significant association between gender and mortality among severe blunt trauma patients,particularly in patients with age < 45 years.These results may highlight the importance of sex hormones in outcomes of severe trauma.
