Cardiometabolic factors and disease duration in patients with Parkinson's disease.

Previous studies have reported that patients with Parkinson's disease (PD) have a favorable cardiometabolic risk profile. The aim of this study was to investigate the relationship between cardiometabolic risk factors and the duration of disease.


One hundred and fifty patients with PD (56.7% men) were studied, measuring body mass index (BMI), waist circumference (WC), body fat percentage (BF%) by impedance, fasting glucose, serum lipids, and transaminases.


In sex- and age-adjusted correlation models, duration of PD was inversely related to BMI (r = -0.20; P < 0.05) and BF% (r = -0.29; P < 0.005). Using multivariable regression models (adjustments: age, gender, smoking status, levodopa dose and, alternatively, BMI, WC, or BF%), high-density lipoprotein (HDL) levels were positively correlated with disease duration (P < 0.01 for all). In models adjusted for WC and BF%, total HDL-cholesterol ratio was also inversely associated with duration of PD (P < 0.05 for both). No other association between biochemical variables and the duration of PD was found. Moreover, no dose-response effect of levodopa on metabolic risk factors was observed.


HDL levels and total HDL-cholesterol ratio were favorably associated with duration of PD. This factor may contribute to cardiometabolic protection in PD. The mechanisms underlying this association deserve further investigation.
