This cohort study evaluated Alzheimer's disease incidence in relation to residential extremely low frequency magnetic fields from indoor transformer stations, using apartment location as an exposure proxy. No significant association was observed between living next to transformer stations and Alzheimer's disease risk (HR 1.02, 95% CI 0.85–1.22). Duration of residence did not materially change risk, and a younger-start subgroup showed a non-significant elevation. The authors note the results did not replicate previously reported positive associations from other residential or occupational studies.
Radiofrequency Electromagnetic Field Emissions and Neurodevelopmental Outcomes in Infants: A Prospective Cohort Study
This prospective cohort study followed 105 neonates/infants for one year and measured household RF-EMF using a selective radiation meter, categorizing exposure into tertiles. Higher household RF-EMF exposure was associated with lower ASQ-3 neurodevelopmental scores, particularly in motor and problem-solving domains, and higher odds of monitor/refer classifications for fine motor and problem-solving. The abstract notes these associations persisted after adjustment for low birth weight, though exposure was measured at a single time point and key confounders (e.g., prenatal phone use, parental interaction) were not assessed.
The association of widely used electromagnetic waves exposure and pregnancy and birth outcomes in Yazd women: a cohort study
This cohort study of 1,666 women in Yazd City examined electromagnetic-wave exposure from commonly used devices during pregnancy and birth outcomes. Longer cell phone call duration during pregnancy was reported to be associated with higher risk of miscarriage, abnormal birth weight, and abnormal newborn height. Increased cordless phone use was also reported to be linked to abnormal birth weight, while other outcomes were assessed but not described as significantly associated in the abstract.
Chicken or egg? Attribution hypothesis and nocebo hypothesis to explain somatization associated to perceived RF-EMF exposure
This longitudinal cohort study examined the temporal relationship between somatization and perceived RF-EMF exposure, comparing the attribution hypothesis with the nocebo hypothesis. Using AMIGO questionnaire data from 2011 and 2015, regression analyses suggested the attribution hypothesis more often explained symptom reporting linked to perceived base station RF-EMF exposure and perceived electricity exposure than the nocebo hypothesis. The authors state this contrasts with prior literature and note that a nocebo effect is not fully excluded.
Prospective cohort study on non-specific symptoms, cognitive, behavioral, sleep and mental health in relation to electronic media use and transportation noise among adolescents (HERMES): study protocol
This protocol describes the third wave of the HERMES prospective adolescent cohort in Switzerland, with follow-up every four months and at one year. The study will assess electronic media use, modeled RF-EMF and transportation noise exposures, and a range of outcomes including cognition, behavior, sleep, mental health, and non-specific symptoms. A subsample will undergo personal RF-EMF measurements and accelerometer-based sleep/physical activity tracking.
