Maybe. The correlation is weak. If you're looking for a stronger correlation, try obesity.

People who are very overweight or obese in middle age (35-55) are significantly more likely to develop Parkinson's after 60, even if they lose the weight prior to diagnosis. Now this could be a pure lifestyle-correlation, but my spidey sense suggests it's causative, knowing how causative obesity is for SO MANY other degenerative and chronic diseases.

The best advice you can give anyone, at any time, for the prevention of nearly every poor health outcome we have a name for is and always will be: don't get fat; if you're fat, stop being fat.
