To examine the association between sitting time and non-alcoholic fatty liver disease among South Koreans aged ≥20 years. Data from the 2016–2018 Korea National Health and Nutrition Examination Survey were used for the analysis. Non-alcoholic fatty liver disease was diagnosed according to a hepatic steatosis index of > 36. Sitting time was categorized into as Q1, Q2, Q3, and Q4 using the age-adjusted quartile with Q4 being the longest sitting hour. Multiple logistic regression analysis was used to examine the association between sitting time and non-alcoholic fatty liver disease in South Korean population. A total of 13,518 participants were enrolled. The odds for having NAFLD in Q1, Q2, Q3, and Q4 (sitting hours) were 1.07 (CI: 0.88–1.31), 1.16 (CI: 1.96–1.41), and 1.34 (CI: 1.11–1.61), respectively. The odds ratio increased in magnitude with longer hours of sitting time (test for trend: P-value = 0.0002). Advising physical exercises and discouraging sedentary activities may help to alleviate NAFLD among the South Korean population.

居住时间与韩国人群非酒精性脂肪活病之间的关联：一项横断面研究。

调查就座时间与年龄≥20岁的韩国人的非酒精性脂肪肝之间的关系。分析使用了2016-2018年韩国国民健康与营养调查的数据。根据≥36的肝脂肪变性指数诊断为非酒精性脂肪肝。就诊时间按年龄调整后的四分位数分为Q1，Q2，Q3和Q4，Q4为最长的就坐时间。多元逻辑回归分析用于检验就座时间与韩国人群非酒精性脂肪肝之间的关系。总共有13,518名参与者。在第1季度，第2季度，第3季度和第4季度（就座时间）获得NAFLD的几率分别为1.07（CI：0.88-1.31），1.16（CI：1.96-1.41）和1.34（CI：1.11-1.61）。随坐时间延长，优势比的幅度增加（趋势测试：P值= 0.0002）。建议体育锻炼和减少久坐不动的活动可能有助于减轻韩国人口中的NAFLD。
