Changes in dietary habits may be associated with the increased prevalence of obesity in South Korea. Therefore, we aimed to identify major dietary patterns and to evaluate the association between these patterns and body mass index (calculated as kg/m(2)) in a Korean population. Typical dietary intake was assessed using a food frequency questionnaire in a cross-sectional study of 1,118 subjects aged 30 to 70 years who underwent health screening examinations. Dietary patterns were derived from 39 predefined food groups using factor analysis. A body mass index >27.5 was used as an indicator of obesity. Logistic regression was used to evaluate the association between obesity and dietary patterns. Three dietary patterns (vegetable-seafood, meat-fat, and snack) were identified and seem to be closely associated with lifestyle factors, including physical activity, smoking, and alcohol consumption. In the multivariate logistic regression model, the meat-fat dietary pattern was positively associated with obesity (odds ratio for high tertile vs low tertile intake=2.78 [95% confidence interval: 1.43 to 5.42]; P for trend=0.008), whereas the vegetable-seafood and snack dietary patterns showed no association with obesity. Results suggest that diets high in meat, oil, and sugar may be associated with obesity status in Korean adults.
饮食习惯的改变可能与韩国肥胖患病率的上升有关。因此，我们旨在确定主要的饮食模式，并评估这些模式与韩国人群体重指数（以kg/m²计算）之间的关联。在一项对1118名年龄在30至70岁接受健康筛查的受试者进行的横断面研究中，使用食物频率问卷评估典型饮食摄入量。饮食模式通过对39个预定义食物组进行因子分析得出。体重指数>27.5被用作肥胖的指标。采用逻辑回归评估肥胖与饮食模式之间的关联。确定了三种饮食模式（蔬菜 - 海鲜、肉类 - 脂肪和零食），它们似乎与生活方式因素密切相关，包括体育活动、吸烟和饮酒。在多变量逻辑回归模型中，肉类 - 脂肪饮食模式与肥胖呈正相关（高三分位数摄入量与低三分位数摄入量的比值比 = 2.78 [95%置信区间：1.43至5.42]；趋势P值 = 0.008），而蔬菜 - 海鲜和零食饮食模式与肥胖无关联。结果表明，富含肉类、油脂和糖的饮食可能与韩国成年人的肥胖状况有关。
