||The experience of 1,190 reference mothers from a case-referent study based on the Finnish Register of Congenital Malformations was scrutinised. Exposure to noise was blindly assessed from a description of the mother's workday by two industrial hygienists. Women exposed to an estimated noise level of 80dB or higher were considered exposed. Threatened miscarriage was not associated with noise exposure alone, but, when it was combined with shift work, the adjusted risk was over twofold. The adjusted risk of pregnancy-induced hypertension was twice as high among the mothers exposed to noise in shift work, and the duration of their pregnancy was shorter. The analyses produced indications of a relation between noise and growth retardation which was not connected with shift work. There were significantly increasing trends in the incidence of these outcomes according to exposure intensity.
