Association of the dietary index for gut microbiota and chronic obstructive pulmonary disease: a cross-sectional study.

ABSTRACT:

Background

Gut microbiota plays a vital role in maintaining human health. The dietary index for gut microbiota (DI-GM), which reflects the diversity of gut microbiota, has not yet been studied for chronic obstructive pulmonary disease (COPD).

Methods

This cross-sectional study analyzed data from adult participants in the 1999-2018 National Health and Nutrition Examination Survey. COPD was identified based on self-reported data. The DI-GM was calculated using dietary recall data. Multivariable logistic regression models were employed to assess the association between DI-GM and COPD. To evaluate the robustness of the association, subgroup and sensitivity analyses were applied.

Results

Increased DI-GM was associated with a decreased prevalence of COPD (OR = 0.96; 95% CI,
