The aim of the study was to evaluate the impact of hygiene routines and characteristics of the daycare centre (DCC) on sickness absence in preschool children.

In Sweden most children attend daycare outside home during daytime. Daycare outside home results in cognitive and social gains for the children, but it also increases the risk of infectious symptoms. About 17%–30% of the respiratory tract infections in preschool children are due to the daycare stay. Factors of importance for sickness absence in DCC have been studied earlier but no study has had a broader focus on routines and daycare characteristics at the same.

In 2003–2004 a national sample of 138 DCCs were visited by a study nurses who assisted in filling in a questionnaire on hygiene routines and daycare characteristics. Thereafter the DCC reported sickness absence on group level during two weeks in the autumn and two weeks in the spring.

Sickness absence was about 10% both in the autumn and in the spring. Only about 10% of the DCC had written rules about hand washing in children but almost all had unwritten rules. More than 50 children at the DCC and no regular contact with the child health centres were found to be of significant importance for sickness absence using a multiple logistic regression model.
