To describe the circumstances around childhood injuries in the home, information on home injuries to children was collected in the emergency room of a pediatric trauma centre as part of an injury surveillance program. During a one-year period, data on 1,538 patients (age < or = 18 years) injured at home were recorded. An inverse s-shape association of home injuries with age was observed. Falls were the leading cause (51%); other children were struck by objects (18%) or sustained cutting/piercing injuries (9%). Age was positively associated with the likelihood of being struck by objects, cutting/piercing, and overexertion, but negatively associated with falls. Playing was the most common activity at time of injury. The peak time of injuries tended to be the early evening. Because most injuries occurred in an environment that seemed safe to parents, reduction in home injuries may require identification of potential hazards in the context of the stages of children's psychological and motor development.
