•A meta-analysis identified 22 studies on parental occupational ELF-MF exposure and risk of childhood nervous system tumors.
•Parental occupational ELF-MF exposure was associated with increased risk of childhood CNS tumors but not neuroblastoma.
•Maternal but not paternal occupational ELF-MF exposure significantly increased risk of childhood CNS tumors.
In conclusion, our results provide limited evidence for the association between maternal occupational exposure to ELF-MF and increased risk of childhood CNS tumors, which should be explained with cautions. Future studies are needed to further evaluate the association of paternal occupational ELF-MF exposure with risk of childhood CNS tumors.
