PASSIVE SMOKING INCREASES THE RISK OF PARKINSON’S DISEASE

October 23, 2017

Tobacco smoking is consistently associated with a reduced likelihood of Parkinson's Disease in men and women. So passive smokers were assessed to see whether they were affected in the same way.

Exposure to passive smoke in social settings was positively associated with Parkinson’s Disease, increasing the likelihood of developing Parkinson’s Disease by 62%. Neither the increasing years of passive smoke exposure, nor the smokiness of the setting affected the likelihood of developing Parkinson’s Disease.

Household exposure during adulthood was associated with a reduced risk of Parkinson’s Disease down to 59% of what would be expected. However, household exposure during childhood was not associated with any alteration in the risk of Parkinson’s Disease. Workplace exposure was also not associated with the risk of Parkinson’s Disease. 

Among lifelong non-smokers, passive smoke exposure combined across all settings and accumulated over a lifetime was only marginally associated with an increased risk of Parkinson’s Disease.
