IMPORTANCE An association between maternal exposure to magnetic field (MF) nonionizing radiation during pregnancy and the risk of attention-deficit/hyperactivity disorder (ADHD) has been reported in both animal and human studies.OBJECTIVES To determine whether maternal exposure to high levels of MF nonionizing radiation is associated with an increased risk of ADHD in offspring by using more accurate measurements of MF nonionizing radiation levels and physician-diagnosed ADHD, rather than self-reports, and to determine whether the association differs for the subtypes of ADHD with or without immune-related comorbidities. DESIGN, SETTING, AND PARTICIPANTS A longitudinal birth cohort study was conducted at KaiserPermanente Northern California among 1482 mother-child pairs whose mothers were participants of an existing birth cohort and whose level of exposure to MF nonionizing radiation was captured during pregnancy in 2 studies conducted from EXPOSURE All participating women wore a monitoring meter for 24 hours during pregnancy to capture the level of exposure to MF nonionizing radiation from any sources. MAIN OUTCOMES AND MEASURESPhysician-diagnosed ADHD and immune-related comorbidities of asthma or atopic dermatitis up to 20 years of age in offspring captured in the Kaiser Permanente Northern California electronic medical record from May 1, 1997, to December 31, 2017.Confounders were ascertained during in-person interviews during pregnancy. RESULTSAmong the 1454 mother-child pairs (548 white [37.7%], 110 African American [7.6%], 325 Hispanic [22.4%], 376 Asian or Pacific Islander [25.9%], and 95 other or unknown [6.5%]; mean [SD] maternal age, 31.4 [5.4] years]), 61 children (4.2%) had physician-diagnosed ADHD. Using Coxproportional hazards regression to account for follow-up time and confounders, compared with children whose mothers had a low level of exposure to MF nonionizing radiation during pregnancy, children whose mothers were exposed to higher levels of MF nonionizing radiation had more than twice the risk of ADHD (adjusted hazard ratio [aHR], 2.01; 95% CI, 1.06-3.81). The association was stronger for ADHD that persisted into adolescence (Ն12 years of age), with an aHR of 3.38 (95% CI, 1.43-8.02). When the subtypes of ADHD were examined, the association existed primarily for ADHD with immune-related comorbidities (asthma or atopic dermatitis), with an aHR of 4.57 (95% CI, 1.61-12.99) for all ADHD cases and an aHR of 8.27 (95% CI, 1.96-34.79) for persistent cases of ADHD. (continued) Key Points Question Could human exposure to magnetic field nonionizing radiation be associated with increased risk of attention-deficit/hyperactivity disorder in children? Findings This birth cohort study found a statistically significant association between a high level of maternal exposure to magnetic field nonionizing radiation, as captured with a monitoring meter, during pregnancy and an increased risk of attention-deficit/ hyperactivity disorder in offspring. The association was stronger for children who received a diagnosi...

“…One of the most important strengths of the study is the use of EMDEX Lite, which objectively showed the MF exposure level from various sources [ 55 ]. Another study demonstrated that pregnant women who were exposed to higher MF levels had 2.72× the risk of miscarriage than those with lower MF exposure [ 27 ], so that the peak MF exposure with risk ratios of 1.8 (with a threshold of approximately 16 mG) as measured by personal monitoring in early pregnancy may be associated with miscarriage risk [ 32 ]. These findings are consistent with previous studies examining the association between high MF exposure and miscarriage risk [ 29 , 30 , 46 ].…”

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 I 2 index. A meta-regression method was employed to investigate the factors affecting heterogeneity between the studies. 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 heterogeneity (p-value of bothwere >0.05). No publication bias was observed. Conclusion Exposure to EMFs above 50 Hz or 16 mG is associated with 1.27× increased risk of abortion. It may be prudent to advise women against this potentially important environmental hazard. Indeed, pregnant women should receive tailored counselling.

“…Reproductive characteristics also considered were previous pregnancy, day 3 FSH levels (IUI/L), initial infertility diagnosis (female factor, male factor, or unexplained), previous intrauterine insemination (IUI) (yes/no), previous IVF (yes/ no), IVF cycle (yes/no), treatment protocol (antagonist, flare, or luteal-phase agonist), E 2 trigger levels (pmol/L), endometrial thickness mm, ICSI (yes/no), and measurement-day nausea (yes/no). Final covariates were included if they were associated with exposure in our cohort, associated with exposure based on previous studies, and known to be a predictor of IVF outcomes (11,13,22). Final models were adjusted for age, BMI, race (white/other), endometrial thickness, IVF (yes/no), and number of changes in environment per day.…”
