Introduction: No studies have provided information on the characteristics of accidents in daily life (ADL) among children under 1 year of age. Yet these ADLs result in an average of 50 deaths per year in France. Methods: A descriptive, retrospective study was conducted using data from the ongoing survey on everyday accidents (EPAC) among children under 1 year of age. Data were collected at the pediatric emergency department of Le Havre Hospital between 2004 and 2013. The analysis was conducted overall and by 3-month age groups. Results: A total of 3,708 children under 1 year of age were victims of a CVA, an average of 1 case per day, with a sex ratio of 1.12. In 85% of cases, the accidents occurred at home. The most common cause was a fall (73%, including 7% on stairs). Children often suffered a contusion or concussion (65%); the head was affected in 73% of cases. Accidents involving a foreign body were more common after the age of 5 months (RR = 2.9, p < 0.001). The hospitalization rate decreased with age: 21% before 3 months, 7% between 9 and 11 months (RR = 0.32, p < 0.001). Falls from changing tables accounted for 9% of the causes of hospitalization due to falls. Conclusion: This study provided the first description in France of the circumstances surrounding non-traumatic brain injuries in children under 1 year of age.
