Abstract

Overview

In this comprehensive population-based case-control study conducted in New Zealand from 2013 to 2016, researchers investigated potential links between occupational hazards and motor neurone disease. Specifically, the focus was on the impact of electric shocks and extremely low-frequency magnetic fields (ELF-MF).

Findings

• Use of job-exposure matrices to assess exposure levels.
• Detailed analysis through logistic regression adjusted for various factors including demographic and lifestyle factors.
• A significant connection was observed between employment in environments with potential for electric shocks and the occurrence of motor neurone disease. The relationship showed a non-linear pattern with risk variations depending on the duration of exposure.
• No significant links were found between ELF-MF exposure and motor neurone disease, underscoring the specific risk posed by electric shocks.

Conclusion

The study bolsters the evidence of a relationship between occupational exposure to electric shocks and motor neurone disease. This highlights an urgent need for revising safety protocols and protective measures in workplaces prone to such exposures.
