Version V1

The goal of this study was to explore the relationship between speech and hearing disorders in children, and to isolate risk factors predisposing children for speech or hearing problems. The survey, a component of a larger project designed to raise the consciousness of pediatricians regarding the relationship between speech and hearing disorders, includes information on the age, sex, number of siblings at home, and position of the child in the families. Also available is information on parents' ages, occupations, and education, as well as data on pregnancy and delivery history, health history, and results of the current physical examination of the child.
