    Abstract : Background: Data on reproductive and developmental effects of extremely low frequency magnetic fields (ELF MFs) are inconclusive. This study tested the hypothesis that maternal exposureexposureSubject Category: Miscellaneous

    . Associations between ELF MF exposure and TTP, low birth weight and SGA were analysed by logistic regression (or linear regression for continuous variables), adjusting for factors known to be associated with the selected pregnancy outcomes, such as maternal smoking, alcohol consumptionconsumptionSubject Category: Properties

    and socioeconomic status. Results: The MF exposure of the mothers was slightly higher than in Finnish residences in general, but very high exposures (>0.4 µT) were rare. No consistent association of ELF MF with TTP, birth weight or SGA was found. Conclusions: ELF MF exposure is not likely to be associated with TTP or prenatal growth at residential exposure levels that were observable in this study.
