Many studies have reported that fermented foods have favorable effects in preventing and managing atopic dermatitis (AD). Although kimchi, a major fermented food, is an important part of the traditional diet in Korea, only a few studies have investigated the relationship between AD and kimchi. This study aimed to examine the association between the risk of AD and kimchi intake among Korean adults aged 19 to 49 years.
We conducted a population-based, cross-sectional study among a total of 7,222 adults who participated in the 2010-2012 Korea National Health and Nutrition Examination Surveys. We defined AD based on responses to a health interview and assessed kimchi intake using a 24-hour recall method administered by well-trained interviewers.
In the multivariable logistic regression analysis, we observed a significantly decreased odds ratio (OR) of having AD according to kimchi consumption after adjustment for confounding factors. In particular, subjects in the third quartile of kimchi consumption (85.0-158 g) had a 32% lower presence of AD than those in the first quartile of kimchi consumption (0-36.0 g) (Odds ratio: 0.68, 95% confidence interval: 0.50-0.92).
We found that consuming 85.0-158 g/day of kimchi was significantly associated with a lower presence of AD. Considering that one serving size of kimchi is 40 g, this corresponds to about 2-4 servings per day. This finding suggests that adequate amount of kimchi intake might have a protective effect against AD.
许多研究报告称发酵食品对预防和管理特应性皮炎（AD）具有有益作用。尽管泡菜作为一种主要的发酵食品，是韩国传统饮食的重要组成部分，但仅有少数研究调查了AD与泡菜之间的关系。本研究旨在探讨19至49岁韩国成年人中AD风险与泡菜摄入量之间的关联。
我们在总共7222名参与2010 - 2012年韩国国家健康与营养检查调查的成年人中开展了一项基于人群的横断面研究。我们根据健康访谈的回答来定义AD，并使用经过良好培训的访谈员采用的24小时回忆法评估泡菜摄入量。
在多变量逻辑回归分析中，在对混杂因素进行调整后，我们观察到根据泡菜消费量，患AD的优势比（OR）显著降低。特别是，泡菜消费量处于第三个四分位数（85.0 - 158克）的受试者患AD的比例比泡菜消费量处于第一个四分位数（0 - 36.0克）的受试者低32%（优势比：0.68，95%置信区间：0.50 - 0.92）。
我们发现每天食用85.0 - 158克泡菜与较低的AD患病率显著相关。考虑到一份泡菜的量为40克，这相当于每天约2 - 4份。这一发现表明适量摄入泡菜可能对AD具有保护作用。
