Diet inflammatory potential modifies the association between tobacco smoke exposure and lung function.

ABSTRACT:

Background

The adverse effect of tobacco smoke exposure on lung function varies among individuals. We aim to investigate whether diet inflammatory potential modifies the association between tobacco smoke exposure and lung function.

Methods

This was a cross-sectional study of 11,382 adults from the 2007-2012 National Health and Nutrition Examination Survey. Tobacco smoke exposure was measured using serum cotinine level, and dichotomized as low or high level according to the race/ethnicity-specific cut-points. Forced expiratory volume in 1 s percent of predicted (FEV₁% predicted), forced vital capacity percent of predicted (FVC% predicted) and FEV₁/FVC were selected to quantify lung function. Diet inflammatory potential was assessed using dietary inflamma
