BACKGROUND & AIM: Sarcopenia is associated with increased risk for several adverse health outcomes including frailty, disability, loss of independence, and mortality. We examined cross-sectional associations between sarcopenia and detailed dietary macronutrient composition in community-living oldest-old men (mean age 87).
Participants were invited to a clinic visit in 2017/2018 including assessments of sarcopenia status using European Working Group on Sarcopenia in Older People's 2 (EWGSOP2) criteria and detailed macronutrient, vitamin D and food intakes retrieved from 3-day food diaries.
Of the 126 participants, 48 had probable sarcopenia and 27 sarcopenia. Sarcopenia was associated with lower energy (p = 0.020), total protein (p = 0.019), plant (p = 0.008) and fish proteins (p = 0.041), total fat (p = 0.015), monounsaturated fatty acids (MUFA) (p = 0.011), polyunsaturated fatty acids (p = 0.002), vitamin D intakes (p = 0.005) and, of fat quality indicators, MUFA: saturated fatty acid-ratio (p = 0.042).
These findings suggest that sufficient energy and protein intakes, but also fat quality may be important along with healthy dietary patterns for prevention of sarcopenia in the oldest-old.
肌少症与多种不良健康结果相关，包括虚弱、残疾、丧失独立性和死亡。我们研究了社区居住的高龄男性（平均年龄 87 岁）肌少症与详细饮食宏量营养素组成之间的横断面关联。
邀请参与者在 2017/2018 年参加诊所就诊，包括使用欧洲老年人肌少症工作组 2（EWGSOP2）标准评估肌少症状态，以及从 3 天饮食日记中获取详细的宏量营养素、维生素 D 和食物摄入量。
在 126 名参与者中，48 名可能患有肌少症，27 名患有肌少症。肌少症与能量摄入较低（p=0.020）、总蛋白（p=0.019）、植物蛋白（p=0.008）和鱼类蛋白（p=0.041）、总脂肪（p=0.015）、单不饱和脂肪酸（MUFA）（p=0.011）、多不饱和脂肪酸（p=0.002）、维生素 D 摄入量（p=0.005）以及脂肪质量指标中的 MUFA：饱和脂肪酸比（p=0.042）有关。
这些发现表明，充足的能量和蛋白质摄入，以及良好的脂肪质量，可能与健康的饮食模式一起，对预防高龄人群的肌少症很重要。
