: Early intervention combining nutrition optimisation with exercise can potentially prevent frailty progression and reverse pre-frailty in older adults. : This 4-month study examined the effectiveness of nutrition education (without oral nutrition supplement use) as part of a multi-domain intervention on the nutritional status and intake of pre-frail community-dwelling older adults and its relationship with sarcopenia markers. : Amongst 172 participants (≥55 years), 5.8% were malnourished, with no significant change in nutritional status throughout the study. Post-intervention, participants consumed significantly higher daily calories, protein, protein per body weight (BW), and calcium ( < 0.001); protein intake at lunch ( = 0.001) and dinner ( = 0.004) also increased. However, 6-month post-intervention daily protein ( = 0.025), protein per BW ( = 0.039), and calcium ( = 0.015) decreased significantly. Sarcopenia markers (handgrip strength (HGS), five-time chair stand test (5STS), and short physical performance battery score (SPPB)) showed no significant difference post-intervention. Well-nourished participants had better HGS ( = 0.005), 5STS ( = 0.026), and SPPB ( = 0.039). Practical nutrition education effectively improved nutritional intake, but the effect was not sustained 6-months post-intervention. : Optimising nutritional status with a focus on improving protein intake, especially at breakfast, to meet minimal intake to stimulate muscle protein synthesis can help prevent sarcopenia and frailty. Future studies should examine factors driving sustainable improvement to prevent frailty progression in this population.
早期将营养优化与运动相结合的干预措施有可能预防老年人身体虚弱的进展并逆转其虚弱前期状态。本为期4个月的研究考察了营养教育(不使用口服营养补充剂)作为多领域干预措施的一部分,对社区居住的虚弱前期老年人营养状况和摄入量的影响及其与肌肉减少症标志物的关系。在172名参与者(≥55岁)中,5.8%的人营养不良,在整个研究过程中营养状况无显著变化。干预后,参与者每日摄入的卡路里、蛋白质、每体重(BW)蛋白质和钙显著增加(<0.001);午餐(=0.001)和晚餐(=0.004)时的蛋白质摄入量也有所增加。然而,干预后6个月,每日蛋白质(=0.025)、每BW蛋白质(=0.039)和钙(=0.015)显著下降。肌肉减少症标志物(握力(HGS)、五次起坐试验(5STS)和简短体能测试电池评分(SPPB))在干预后无显著差异。营养良好的参与者HGS更好(=0.005)、5STS更好(=0.026)、SPPB更好(=0.039)。实用的营养教育有效改善了营养摄入量,但干预后6个月效果未持续。以提高蛋白质摄入量为重点优化营养状况,尤其是早餐时的摄入量,以达到刺激肌肉蛋白质合成的最低摄入量,有助于预防肌肉减少症和身体虚弱。未来的研究应考察推动可持续改善以预防该人群身体虚弱进展的因素。
