[Video display terminals and pregnancy. Evaluation of risks by consensus. Report of an INSERM working group]

INSERM established a working group to evaluate the effects of VDT work on pregnancy outcome. The group examined all available scientific papers concerning radiation emitted by VDTs, animal experimentation, and epidemiological studies. An estimation of risk was made for each outcome (congenital malformations, spontaneous abortion, stillbirth, premature birth, and low birthweight) according to a decisional algorithm, a method that gives preponderance to epidemiological arguments. On this basis, the group was able to show that the use of VDTs poses no increased risk of congenital anomalies, stillbirth, or premature birth. Consensus evaluation of divergent epidemiological results concluded that VDT work is not a risk factor significantly affecting spontaneous abortions. The risk of low birthweight could not be validly assessed.
