Objectives. The study's objective was to examine and compare injury ra
tes of children ages 6 months to 6 years in day care centers and homes
. More specifically, we tested the hypothesis that the injury rate is
lower in day care centers than at homes, as suggested by previous stud
ies. Methods. A comprehensive prospective injury registration was carr
ied out in Stavanger, Norway, during 1992. We obtained data from this
system to identify injuries occurring in day care centers, homes, and
other places during 1992. Exposure-adjusted incidence rates were calcu
lated to compare the risk of injury at day care centers, homes, and ot
her places. We also obtained data from medical records on use and cost
s of medical care. In addition, a parent questionnaire was developed a
nd used to gather data on the amount of injury-related restricted acti
vity. Results. Among 9454 children ages 6 months to 6 years in Stavang
er, 770 injuries occurred during 1992: 96 in day care centers, 472 at
home, and 202 at other places. For children ages 6 months to 2 years,
the rate of injuries was significantly lower in day care centers than
at home (1.2 and 2.5, respectively, per 100 000 children-hours), but f
or children ages 3 to 6, the rates of injuries were similar in day car
e centers and at home (1.3 and 1.5, respectively, per 100 000 children
-hours). The great majority of children attending day care centers wer
e from 3 to 6 years of age. No significant differences were found in t
he severity of the injuries. Conclusions. For children ages 3 to 6 yea
rs, which included most of the children attending day care centers in
Stavanger, Norway, day care centers were not found to be safer than ho
mes. We think continuing attention should be paid to injury control in
day care centers.
