Reduced skeletal muscle mass in older populations is independently associated with functional impairment and disability, resulting in increased risk of mortality and various comorbidities. This study aimed to examine the association between major dietary pattern and low muscle mass among Korean middle-aged and elderly populations. A total of 8136 participants aged ≥50 years were included from a cross-sectional study based on the 2008-2011 Korea National Health and Nutrition Examination Survey. The following four distinct dietary patterns were derived using factor analysis: "Condiment, vegetables, and meats"; "wheat flour, bread, fruits, milk, and dairy products"; "white rice, fish, and seaweeds"; and "whole grain, bean products, and kimchi". A higher "white rice, fish, and seaweeds" pattern score was associated with a lower prevalence of low muscle mass in both men and women, whereas a higher "condiment, vegetables, and meats" pattern score was associated with a higher prevalence of low muscle mass in men. A dietary pattern based on white rice, fish, and seaweeds can be helpful in protecting against loss of skeletal muscle mass in Korean middle-aged and elderly populations. Future research is paramount to confirm the causal association between dietary pattern and the risk of low muscle mass.
老年人骨骼肌量减少与功能障碍和残疾独立相关，导致死亡率和各种合并症风险增加。本研究旨在探讨韩国中年和老年人主要饮食模式与低肌肉量之间的关系。本研究基于 2008-2011 年韩国国家健康和营养检查调查的横断面研究，共纳入了 8136 名年龄≥50 岁的参与者。采用因子分析得出以下四种不同的饮食模式：“调味料、蔬菜和肉类”、“小麦粉、面包、水果、牛奶和奶制品”、“白米、鱼和海藻”和“全谷物、豆类和泡菜”。较高的“白米、鱼和海藻”模式评分与男性和女性低肌肉量的患病率降低相关，而较高的“调味料、蔬菜和肉类”模式评分与男性低肌肉量的患病率升高相关。以白米、鱼和海藻为基础的饮食模式有助于预防韩国中年和老年人骨骼肌量的减少。未来的研究对于证实饮食模式与低肌肉量风险之间的因果关系至关重要。
