Isolating the effects of a single nutrient or food in relation to health outcomes including increased skeletal muscle mass is a challenging task because dietary constituents are highly correlated and synergistic. Hence, diet pattern analysis may be used to investigate the role of certain diets in health outcomes. The present study investigated the dietary patterns and their relationship to skeletal muscle mass in Korean adults. Data were extracted from the 2008-2011 Korea National Health and Nutrition Examination Surveys. To explore the dietary patterns of the study subjects, factor analysis was performed using data obtained from a 24-hour recall. The skeletal muscle index according to dietary pattern scores was then investigated to estimate the changes in skeletal muscle mass. Three patterns were initially identified from the factor analysis. Of these vegetables and fish (VF) pattern was the primary factor with high reliability and was a common factor in sex-separated analyses. The VF pattern scores were positively associated with increased skeletal muscle mass in both men and women. Further analysis according to quartile levels of VF pattern scores showed a positive association between skeletal muscle mass and VF pattern in men but not in women. These results suggest that dietary patterns focused on vegetables and seafoods may contribute to increased skeletal muscle mass in Korean men but that sex difference should be considered in nutrition care for skeletal muscle health.
分离单一营养素或食物对包括增加骨骼肌质量在内的健康结果的影响是一项具有挑战性的任务，因为膳食成分之间高度相关且具有协同作用。因此，饮食模式分析可用于研究某些饮食在健康结果中的作用。本研究调查了韩国成年人的饮食模式及其与骨骼肌质量的关系。数据取自2008 - 2011年韩国国家健康与营养检查调查。为了探究研究对象的饮食模式，使用从24小时饮食回顾中获得的数据进行了因子分析。然后根据饮食模式得分调查骨骼肌指数，以估计骨骼肌质量的变化。因子分析最初确定了三种模式。其中，蔬菜和鱼类（VF）模式是具有高可靠性的主要因素，并且是按性别分开分析中的共同因素。VF模式得分与男性和女性骨骼肌质量增加均呈正相关。根据VF模式得分的四分位数水平进行的进一步分析表明，男性的骨骼肌质量与VF模式呈正相关，而女性则不然。这些结果表明，以蔬菜和海鲜为重点的饮食模式可能有助于增加韩国男性的骨骼肌质量，但在骨骼肌健康的营养护理中应考虑性别差异。
