研究问题
BackgroundFrailty is common in older adults and associated with inadequate nutrition, reduced physical function, and increased vulnerability.
方法
Searches were conducted in PubMed, CINAHL, and Scopus.；Due to heterogeneity, a narrative synthesis without meta-analysis was performed.SummaryOf 2447 records identified, 10 publications met the inclusion criteria.；Certainty of evidence ranged from low to high, limited by small samples and heterogeneity.Although some studies reported favourable effects of combined nutrition and exercise interventions, the available evidence is insufficient to determine whether nutrition adds benefits beyond exercise alone.
核心结论
Searches were conducted in PubMed, CINAHL, and Scopus.；Randomised controlled trials explicitly defining frailty were eligible.；Two reviewers independently screened and assessed methodology using RoB 2.0.；Certainty of evidence was evaluated using Grading of Recommendations Assessment, Development, and Evaluation. ‖ 结论：Further standardised trials are needed to clarify the role of nutritional components within combined nutrition-exercise interventions in frailty management.
