Abstrakt: Introduction: Anemia may contribute significantly to the onset of Parkinson's disease (PD). Current research on the association between anemia and PD risk is inconclusive, and the relationships between anemia-related blood cell indices and PD incidence require further clarification. This study aims to investigate the relationships between anemia, blood cell indicators, and PD risk using a thorough prospective cohort study.
Methods: We used data from the UK Biobank, a prospective cohort study of 502,649 participants, and ultimately, 365,982 participants were included in the analysis. Cox proportional hazards models were utilized to adjust for confounding factors, aiming to thoroughly explore the associations between anemia and blood cell indices with the risk of incident PD. The interaction between anemia and Polygenic Risk Score (PRS) for PD was also examined. Linear regression and mediation analyses assessed potential mechanisms driven by brain structures, including grey matter volume.
Results: During a median follow-up of 14.24 years, 2513 participants were diagnosed with PD. Anemia considerably increased PD risk (hazard ratio [HR] 1.98, 95 % confidence interval [CI]: 1.81-2.18, P < 0.001) after adjustments. Those with high PRS for anemia had an 83 % higher PD incidence compared to low PRS participants. Sensitivity analyses confirmed result robustness. Linear regression showed that anemia correlated with grey matter volumes and most white matter tracts. Furthermore, mediation analyses identified that the volume of grey matter in Thalamus mediates the relationship between anemia and PD risk.
Conclusion: In summary, we consider there to be a substantial correlation between anemia and increased PD risk.
