Childhood accidents: the relationship of family size to incidence, supervision, and rapidity of seeking medical care.

Background: Large family size may be a risk factor for childhood accidents. A possible association with quality of child supervision and rapidity of seeking medical care has not been fully evaluated.

Objectives: To determine whether children with multiple siblings are at increased risk for accidents, to assess whether quality of child supervision varies with family size, and to evaluate the relationship of family size with the rapidity of seeking medical care after an accident.
