Background: This study aimed to explore the association between chronic obsructive pulmonary disease (COPD) and dietary inflammatory index (DII) in Korean male adults.
Methods: The subjects consisted of 4,267 Korean male adults aged over 40 years in the National Health and Nutrition Examination Survey from 2016-2019. Subjects were categorized into four groups based on quartiles of dietary inflammatory index score.
Results: Individuals with high DII score had poor health habits such as drinking, smoking, activity limitations. The intake of anti-inflammatory items except monounsaturated fatty acid decreased as the DII item score increased. The higher the score of DII, the lower the forced expiratory volumn in 1 sec (FEV1), forced vital ca- pacity (FVC), FEV1/FVC which are lung function measures. The prevalence of COPD increased in the highest quartile of the DII score.
Conclusions: It was found that dietary inflammatory index was significantly associated with lung function and COPD. The promotion of a healthy diet with anti-inflammatory properties may help to prevent COPD in male adults.
