Incidence, and factors associated with moderate/severe pediatric traumatic brain injury in children aged 5-15 years in western, Mexico

Objective: The study objectives were to estimate the standardized incidence and evaluate factors associated with moderate/severe pediatric traumatic brain injury (p-TBI) in children aged 5-15 years in Western, Mexico. Methods: The study was cross-sectional in design. We estimated the standardized incidence of moderate/severe p- TBI using the direct methods of the World Health Organization (WHO) standard populations. We utilized the Glasgow Coma Scale (GCS) to identify moderate/severe p-TBI patients (GCS <= 13). Logistic regression analysis was applied to evaluate variables associated with moderate/severe p-TBI. Results: The standardized incidence of patients diagnosed with moderate/severep-TBI was 31.0/100,000 personyears (95 % CI 28.7-33.4). According to age, the moderate/severe TBI group was included. A total of 254 (38.5 %) patients were aged 5-9 years, 343 (52.0 %) were aged 10-14 years, and 62 (9.5 %) were aged 15 years. Factors associated with moderate/severe TBI in the crude analysis were male sex (OR 5.50, 95 % CI 4.16-7.39, p < 0.001), primary school (OR 2.15, 95 % CI 1.62-2.84, p < 0.001), and falls (OR 1.34, 95 % CI 1.02-1.77, p = 0.035). Factors associated with moderate/severe p-TBI in the adjusted analysis were male sex (OR 6.12, 95 % CI 4.53-8.29, p < 0.001), primary school (OR 3.25, 95 % CI 2.31-4.55, p < 0.001), and falls (OR 1.78, 95 % CI 1.28-2.47, p < 0.001). Conclusion: The incidence of moderate/severe p-TBI in children aged 5-15 years in western Mexico in this study was higher than that in other studies. One of the biggest factors associated with moderate/severe p-TBI was male sex, specifically those with lower education levels and those who were prone to falls.
