Sick building symptoms in office workers in northeastern France: a pilot study.

A cross sectional study with control was performed to identify sick building syndrome symptoms in office workers in northern France, based on an air conditioned and a naturally ventilated building. Found that exposure to air conditioning was linked to an increased prevalence of symptoms, and increased sickness absence. Two determinants not previously described resulting from logistic regression were family history of respiratory diseases and 'do-it-yourself' activities.
