The association between Planetary Health Diet Index (PHDI) and chronic obstructive pulmonary disease (COPD): the mediating role of dietary inflammatory index (DII).

ABSTRACT:

Background

Given global changes in the environment and dietary habits, it is critical to understand the potential impact of dietary factors and dietary inflammation on respiratory diseases, including COPD. Studying these relationships can help develop more effective prevention strategies. PHDI is a dietary scoring system designed to balance human health and environmental sustainability by promoting increased consumption of plant-based foods and reduced intake of red meat, sugar, and highly processed foods. In contrast, DII quantifies the inflammatory potential of a diet. This study examines the association between PHDI and COPD and assesses whether DII mediates this relationship.

Methods

We used subgroup analysis, smooth curve fitting, and multivariable logistic regression t
