Study type: Epidemiological study

A meta-analysis on residential exposure to magnetic fields and the risk of amyotrophic lateral sclerosis. epidem.

Published in: Rev Environ Health 2018 [in press]

Aim of study (acc. to author)

A meta-analysis was performed to evaluate the association between residential exposure to extremely low-frequency magnetic fields and the risk of amyotrophic lateral sclerosis.

Further details

Following 5 studies were included: Huss et al. (2009), Marcilio et al. (2011), Frei et al. (2013), Seelen et al. (2014) and Vinceti et al. (2017).

Group Description
Reference group 1 distance between residence and power line: ≥ 200 m
Group 2 distance between residence and power line: < 200 m
Reference group 3 magnetic flux density: ≤ 0.1 µT
Group 4 magnetic flux density: > 0.1 µT

Conclusion (acc. to author)

No increased risk of amyotrophic lateral sclerosis was observed (pooled RR: 0.71, CI 0.48-1.07) for the most exposed population group (27 cases either living < 200  m distance from high voltage power lines or magnetic flux density > 0.1 μT). Little heterogeneity and no indication for publication bias was seen.
The authors concluded that no evidence for an association between residential exposure to extremely low-frequency magnetic fields and the risk of amyotrophic lateral sclerosis was found, although the number of exposed cases was low.
