Abstract
The possibility of an association of early pregnancy loss (EPL) with r esidential exposure to ELF magnetic fields was investigated in a case- control study. Eighty-nine cases and 102 controls were obtained from t he data of an earlier study aimed at investigating the occurrence of E PL in a group of women attempting to get pregnant. Magnetic-field expo sure was characterized by measurements in residences. Strong magnetic fields were measured more often in case than in control residences. In an analysis based on fields measured at the front door, a cutoff scor e of 0.5 A/m (0.63 muT) resulted in an odds ratio of 5.1 (95% confiden ce interval 1.0-25). The results should be interpreted cautiously due to the small number of highly exposed subjects and other limitations o f the data.
