Association Between Dietary Fiber and Parkinson's Disease in the United States: NHANES 2005-2018.

ABSTRACT:

Objective

To explore the association between dietary fiber (DF) intake and the prevalence of Parkinson's disease (PD) in American adults on the basis of cross-sectional data.

Methods

This cross-sectional study utilized data from the National Health and Nutrition Examination Survey (NHANES) spanning from 2005 to 2018. Multivariable logistic regression models and trend analyses were employed to examine the relationship between average dietary fiber intake (ADFI, g/day) and PD prevalence. Additionally, restricted cubic spline (RCS) models were used to investigate the potential nonlinear dose-response relationship between ADFI and PD. Subgroup interaction analyses were conducted as exploratory analyses to evaluate the association between ADFI and PD across different subgroups.
