Abstract
Admissions to hospital experienced by 991 Dunedin children in the first five years of life are described. Changes in behaviour reported by the mothers as following these admissions were related to the age of the child, circumstances of admission, and extent of contact with parents. Twenty-seven percent of the children had been in hospital and 7% more than once. The majority of admissions were short, particularly for the older children, and parent contact was usual. The majority of admissions were not followed by reported changes in behaviour. Children between 13 and 36 months had the highest incidence of reported behaviour deterioration (25%). Children between 36 and 60 months had the highest incidence of improved behaviour (22%). These results are discussed in relationship to other research on the effects of admission to hospital on young children.
