Effect of extremely low-frequency electromagnetic radiation on pregnancy outcome: A meta-analysis
Abstract
Overview
Extremely low-frequency electromagnetic radiation (ELF-EMF), which ranges from 1 to 300 Hz, is produced by various electrical devices and power systems. The impact of ELF-EMF exposure on pregnancy outcomes has been explored due to mixed results in prior studies.
Methodology
This meta-analysis engaged in a comprehensive search using databases like PubMed, Web Of Science, Cochrane Library, Embase, and EBSCO to compile relevant studies up to March 10, 2021. Manual retrieval supplemented the search. Two researchers independently screened and extracted data, utilizing Review Manager 5.3 for analysis.
Findings
- Comparison between pregnant women with close proximity to ELF-EMF and a control group showed no significant increase in risks concerning miscarriage, stillbirth, birth defects, and preterm delivery.
Conclusion
No direct correlation between ELF-EMF exposure and several major adverse pregnancy outcomes was identified. However, issues such as small gestational age and low birth weight remain uncertain. Further high-quality, large-sample research across varied regions is essential for more definitive conclusions.
