Implication
Prospective cohort study finds higher serum cholesterol reduces Parkinson's disease risk in older adults, indicating potential protective roles of lipids or coenzyme Q10 against oxidative stress.
Key Points
- To assess the prospective association between serum total cholesterol levels and the subsequent risk of Parkinson's disease in an older population.
- Conducted a prospective, population-based cohort study (Rotterdam Study) involving 6,465 participants aged 55 years or older.
- Performed repeated in-person examinations with an average follow-up of 9.4 years between 1990 and 2004.
- Higher serum total cholesterol levels were associated with a significantly decreased risk of Parkinson's disease (age- and sex-adjusted HR = 0.77 per mmol/L increase, 95% CI: 0.64–0.94), displaying a dose-effect relation.
- The inverse association was restricted to women and remained unchanged following adjustment for multiple potential confounding factors.
