The ingest of iron through feeding increases the chance of getting Parkinson's disease?
Study Design:
This overview article contained 5 studies with 126507 participants.
Results and conclusions:
The researchers found that a moderate iron intake through feeding the chance of getting Parkinson's disease not significant with 8% [RR = 1.08, 95% CI = 0.61-1.93, p = 0.787] increased.
The researchers found that a high iron intake through feeding the chance of getting Parkinson's disease not significant with 3% [RR = 1.03, 95% CI = 0.83-1.30, p = 0.309] increased.
The researchers found that a high iron intake through feeding the chance of getting Parkinson's disease among Europeans significantly with 47% [RR = 1.47, 95% CI = 1.17-1.85, p = 0.001] increased.
The researchers found that a high iron intake through feeding the chance of getting Parkinson's disease among men significantly with 43% [RR = 1.43, 95% CI = 1.01-2.01, p = 0.041] increased.
The researchers found that both a moderate as a high zinc-and copper intake through feeding the chance of getting Parkinson's disease not significantly increased.
The researchers found that daily 10 mg of iron through feeding the chance of getting Parkinson's disease among Europeans significantly with 18% [RR = 1.18, 95% CI = 1.02-1.37] increased.
Significant because RR of 1 was not in 95% CI from 1.02 to 1.37. RR of 1 is, there is no risk.
On the basis of the found results the researchers concluded that daily 10 mg of iron through feeding the chance of getting Parkinson's disease among Europeans increased.
