Occupational and Environmental risk factors for Motor Neurone Disease
The aims of this project are:
- To describe the epidemiology of motor neurone disease (MND) in New Zealand
- To estimate the proportion of cases of MND in New Zealand that are due to occupational exposures previously observed (including electrical injury/electrical occupations/EMFs, veterinarians, radio/dental/MD/x-ray/laboratory technician, cutting/cooling or lubricating oils, antifreeze or coolants, agricultural chemicals, welding and/or soldering, metals including lead, aluminium and iron, organic solvents, and methyl bromide)
- To estimate the proportion of cases of MND in New Zealand that are due to personal and lifestyle factors previously observed (including smoking, increasing age, family history of MND, education level attained, and participation in sports with a risk of head injuries)
- To estimate the proportion of cases of MND in New Zealand that are due to environmental exposures previously observed (including fumigants such as methyl bromide, other agricultural chemicals; rural or urban residence)
- To identify new occupational, personal and lifestyle factors, and environmental exposures that are risk factors for developing MND
Data collection has now been completed.
