Visual display units and pregnancy outcome: a prospective study.

This paper presents the results of a prospective study of the impact of work with visual display units (VDUs) and associated ergonomic and stress variables on pregnancy outcome and infertility. An apparent relationship between VDU use and pregnancy outcome in retrospective data probably reflected the operation of recall bias. Prospective data did not reveal any evidence for an adverse effect of VDUs on pregnancy in this sample, or any mechanism by which such an effect could occur. There was no evidence for any effect of VDU use on infertility. Implications for working women and future research are also presented.
