Residential exposure to electromagnetic fields and risk of amyotrophic lateral sclerosis: a dose-response meta-analysis epidem.

Published in: Sci Rep 2021; 11: 11939

Aim of study (acc. to author)

A meta-analysis was performed to assess the dose-response relationship between amyotrophic lateral sclerosis and residential exposure to extremely low frequency magnetic fields.

Further details

Following six studies were included in the meta-analysis: Frei et al. (2013), Huss et al. (2009), Marcilio et al. (2011), Seelen et al. (2014) and reanalyzed data of Vinceti et al. (2017) and Filippini et al. (2020).

Results (acc. to author)

No increased risk was observed for amyotrophic lateral sclerosis with residential exposure to extremely low frequency magnetic fields (distance-based analysis: RR 0.87, CI 0.63–1.20; modelling-based analysis: RR 0.27, CI 0.05–1.36). Analysis of the dose-response relationship also showed little association between distance from power lines and amyotrophic lateral sclerosis, with no evidence of any threshold.
The authors concluded that they found scant evidence of an association between residential magnetic fields exposure and amyotrophic lateral sclerosis.
