Abstract:
Objective:To investigate the sex differences in severe traumatic death patients of different ages.Methods:A total of 408 patients with severe trauma who received treatment in The Second Affiliated Hospital of Zhejiang University School of Medicine and Taizhou First People's Hospital from June 2017 to June 2022 were retrospectively analyzed. These patients were divided into the children group (≤ 14 years old, n = 47), the adult group (14-50 years old, n = 171), and the older adult group (> 50 years old, n = 90). Multivariate logistic regression was used to evaluate the difference in sex-based mortality among the groups. Nonlinear regression was used to evaluate the mutual interaction of increasing age and sex on the predicted survival rate. Results:Traffic accidents were the most common cause of death among men in the adult group (58.93%, χ2 = 7.95, P = 0.027). Falls were the most common cause of death among men in the older adult group (57.36%, χ2 = 8.63, P = 0.001). The Injury Severity Score of women in the adult and older adult groups was significantly higher in women than that of men in the same group [adult group: men: (24.39 ± 4.17) points, women: (26.32 ± 4.31) points, t = 2.84, P = 0.005). The incidence of post-traumatic complications in the older adult group was very higher in men than in women (respiratory failure: 28.68% in men, 14.75% in women, χ2 = 4.37, P = 0.036; circulatory failure: men: 27.13%, women: 13.11%, χ2 = 4.64, P=0.031; neuropsychiatric disorders: men: 20.93%, women: 8.20%, χ2 = 4.79, P = 0.029; respiratory infection: men: 31.78%, women: 18.03%, χ2 = 5.55, P = 0.047; other infectious diseases: men: 28.68%, women: 13.11%, χ2 = 0.69, P = 0.018). After adjusting for covariates, the mortality rate of men in the older adult group was significantly higher than that of women in the same group ( OR: 1.261, 95% CI: 1.185-1.343, P < 0.001). With the increase of age, the predicted survival rate after the trauma in patients of different sexes also decreased, in particular in men aged > 50 years (interaction P = 0.051). Among patients with blunt and severe head trauma, age-related mortality decline in patients aged > 50 years had a strong interaction with sex (interaction P = 0.002). In patients with penetrating trauma, there was a weak interaction between the predicted survival rate of different sexes (interaction P = 0.192). Conclusion:There is no significant difference in age-related change in post-traumatic mortality between different sexes. In the population aged > 50 years, men have a relatively higher risk of death than women.
