A review of current evidence concerning possible reproductive hazard from VDUs

Abstract

Widespread concern exists as to the possible hazards to reproduction of work with visual display units or VDUs, the use of which has expanded dramatically in the last 20 years. This is part of a more general concern about the health effects of such technology which is being tackled by ergonomic research recommendations. Concern over a possible hazard to pregnancy appears to have its origins in ‘cluster’ reports, but these are not proof of an effect. Critical review of some eleven studies in this area reveals that there are a variety of methodological problems involved in the design and interpretation of the results of this research, but their authors have generally concluded that they found no evidence of an effect. Research continues, but there are clear indications of a need for prospective studies which will provide reassurance that this technology can be used safely by working women planning a family, and investigate the possible role of factors such as stress and the effect of VDU work on menstruation.
