Unintentional injury in children is a worldwide public health problem, as it increases the health burden and is a leading cause of death among children. It is important to understand the differences between different age groups of children in regard to unintentional injury, in order to effectively implement child safety education. The present study aimed to determine the current trends of unintentional injury in children, and to identify the differences between different age groups of children with regard to unintentional injury. We identified 1,521 children who attended an 18-month health checkup (18-month group), and 1,368 children who attended a 36-month health checkup (36-month group), between January 1, 2014 and December 31, 2014. The rate of hospital visits associated with unintentional injury was 10.6% (161/1,521) in the 18-month group, and 13.1% (180/1,368) in the 36-month group. In both groups, present/past illness was associated with hospital visits, and in the 36-month group, hospital visits were more common in boys than in girls. The number of unintentional injuries that occurred outdoors was higher in the 36-month group than in the 18-month group. Unintentional injuries resulting from accidental ingestion and falls were more common in the 18-month group, while unintentional injuries resulting from turning over were more common in the 36-month group. In conclusion, the number of hospital visits for unintentional injury might be higher, and the number of preventive actions taken by mothers might be lower, among children attending the 36-month health checkup than among those attending the 18-month health checkup.
