Appendectomy and risk of Parkinson's disease in two large prospective cohorts of men and women.

ABSTRACT:

Background

Prior work on appendectomy and PD has produced mixed results. In this study we examined whether history of self-reported appendectomy was related to risk of incident Parkinson's disease in the Nurses' Health Study and the Health Professionals Follow-up Study.

Methods

We used the Cox proportional hazards model to estimate the hazard ratio of Parkinson's disease associated with self-report of appendectomy in men and women. Among women, we estimated the hazard ratio of Parkinson's disease associated with appendectomy for appendicitis and incidental appendectomy.

Results

In pooled analyses, self-report of any appendectomy was not related to Parkinson's disease risk: the hazard ratio of Parkinson's disease comparing participants who reported any appendectomy wit
