This study was performed to investigate the relationship between dietary factors and asthma in a representative population-based sample of 19,659 men and women, aged 19?64 years, using data from the fourth and fifth Korean National Health and Nutrition Examination Survey (KNHANES), 2007?2011. The presence of asthma was based on self-reported physician diagnosis of asthma in the Health Interview Surveys. Food intake was estimated by trained interviewers using a 24-h recall method. The prevalence of asthma in Korean adults was 2.4%. Adults with asthma consumed fewer amounts of kimchi (P=.0444) and fish (P=.0175) but had a higher cereal intake than those without asthma (P=.0056). Multiple logistic regression analysis after controlling for confounding factors showed a significant inverse relationship between kimchi consumption and the prevalence of asthma [odds ratio (95% confidence interval) for subjects consuming 1 to <2 servings (40?79.9?g), 2 to <3 servings (80?119.9?g), and ≥3 servings (≥120?g), relative to those consuming <1 serving (<40?g): 0.726 (0.534?0.987), 0.506 (0.348?0.736), and 0.678 (0.502?0.916), respectively; P for trend=0.0131]. These results warrant future studies to explore the mechanisms responsible for the association between kimchi consumption and asthma.
