Effect of electromagnetic field on abortion: A systematic review and meta-analysis

خلاصه انگلیسی

Background - The increasing use of new technologies by pregnant women inevitably exposes them to the risks of the electromagnetic fields (EMFs). According to the World Health Organization, EMFs are the major sources of pollutants which harm human health. This study was aimed to evaluate the effects of EMF exposure on abortion. Methods - Web of Science, Cochrane Library, MEDLINE, PubMed, EMBASE, Scopus, and Google Scholar were searched until 2021. Pooled odds ratio (OR) with 95% confidence interval (CI) was estimated using a random-effects model. Heterogeneity was explored using Cochran's Q test and I2 index. A meta-regression method was employed to inves-tigate the factors affecting heterogeneity between the stu-dies. The Newcastle-Ottawa scale was used to assess the credibility of the studies. Results - Eligible studies (N = 17) were analyzed with a total of 57,693 participants. The mean maternal age (95% CI) was 31.06 years (27.32-34.80). Based on meta-analysis results, the pooled estimate for OR of EMF with its effects was 1.27 (95% CI: 1.10-1.46). According to the results of meta-regression, sample size had a significant effect on heterogeneity between studies (p: 0.030), but mother's age and publication year had no significant effect on het-erogeneity (p-value of bothwere >0.05). No publication bias was observed. Conclusion - Exposure to EMFs above 50 Hz or 16 mG is associated with 1.27x increased risk of abortion. It may be prudent to advise women against this potentially impor-tant environmental hazard. Indeed, pregnant women should receive tailored counselling.
