A comprehensive investigation of the relationship between dietary fatty acid intake and preserved ratio impaired spirometry: multimethodology based on NHANES.

ABSTRACT:

Background

Preserved ratio impaired spirometry (PRISm) has been identified as a potential precursor to chronic obstructive pulmonary disease (COPD) and demonstrates a significant correlation with unfavorable clinical outcomes. Modification of PRISm-related risk factors is a higher priority in public health than treating PRISm itself. Dietary fatty acids (FAs) affect human health through a variety of physiological pathways. However, no prior research has investigated the associations of FAs and their subclasses with PRISm, particularly the combined effects of different types of FAs.

Methods

Data analysis was conducted on 8,836 individuals drawn from the NHANES dataset spanning the years 2007 to 2012. Logistic regression and smooth curve fitting were first used to assess relat
