Comparative efficacy of exercise, nutrition, and combined exercise and nutritional interventions in older adults with sarcopenic obesity: a protocol for systematic review and network meta-analysis
Abstract
Sarcopenic obesity (SO) in older adults is associated with certain adverse outcomes, including falls, fractures, and disability, all of which affect patient quality of life, represent an economic burden, and potentially enhance the risk of death. Although a number studies have examined the effects of exercise, nutrition, and combined exercise and nutritional interventions on older adults with SO, the optimal therapeutic approach has yet to be sufficiently established. In this systematic review and network meta-analysis (NMA) protocol for SO in older adults, we aim to compare the combined effects of exercise and nutrition with those of exercise or nutritional interventions alone on the body composition and physical performance of older adults with SO. The PubMed, Web of Science, Embase, OVID, CINAHL, CNKI, Wanfang Data, and VIP databases will be used to systematically search for randomized controlled trials published from the time of database inception to December 2024. Outcomes will include body composition and physical performance, and data will be extracted independently by two researchers. In cases of disagreement, a consensus will be reached by consulting a third researcher. The Cochrane risk-of-bias tool will be used to assess randomized controlled trials, and data analysis will be performed using Stata 15.0 and R software, based on homogeneity, sensitivity, transitivity, consistency, and publication bias tests. By comprehensively assessing the relative efficacies of…
