Abstract

Introduction: Oxidative stress is proposed to be one of the potential mechanisms leading to neurodegeneration in Parkinson's disease. However, previous epidemiologic studies investigating associations between antioxidant vitamins, such as vitamins E and C and carotenoids, and PD risk have produced inconsistent results. Objective: The objective of this work was to prospectively examine associations between intakes of antioxidant vitamins, including vitamins E and C and carotenoids, and PD risk. Methods: Cases were identified in two large cohorts: the Nurses' Health Study and the Health Professionals Follow‐up Study. Cohort members completed semiquantitative food frequency questionnaires every 4 years. Results: A total of 1036 PD cases were identified. Dietary intakes of vitamin E and carotenoids were not associated with PD risk; the multivariable‐adjusted relative risk comparing extreme intake quintiles were 0.93 (95% confidence interval: 0.75–1.14) and 0.97 (95% confidence interval: 0.69–1.37), respectively. Dietary vitamin C intake was significantly associated with reduced PD risk (relative risk: 0.81; 95% confidence interval: 0.65–1.01; p trend , 0.01); however, this result was not significant in a 4‐year lag analysis. For vitamins E and C, intake from foods and supplements combined were also unrelated to PD risk. Conclusions: Our results do not support the hypothesis that intake of antioxidant vitamins reduces the risk of PD. © 2016 International Parkinson and Movement Disorder Society

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
