Association between dietary fiber intake and obesity in US adults: from NHANES 1999-2018.

ABSTRACT:

Background

Previous studies have demonstrated that dietary fiber reduces the incidence of diabetes or hyperlipidemia, but it remains unclear how dietary fiber intake relates to obesity incidence.

Methods

A total of 39,184 adults were obtained from the National Health and Nutrition Examination Survey (NHANES) from 1999 to 2018. Multifactorial logistic regression analysis and Cox regression analysis were used to investigate the correlation between dietary fiber intake and obesity. Restricted cubic spline (RCS) analyses were used to describe the dose-response correlation between dietary fiber intake and the incidence of obesity. The robustness of the results was enhanced by Kaplan-Meier survival analyses and subgroup analyses.

Results

After adjusting for confounders, die
