  • Effect of different nutrient interventions on physical function of elderly with frailty: a network meta-analysis

    Objective To systematically review the effect of different nutrient interventions on the physical function of elderly people with frailty through network meta-analysis. Methods The PubMed, Cochrane Library, EMbase and Web of Science were electronically searched to collect randomized controlled trials of different nutrient interventions on physical function of the elderly with frailty, from database inception to June 30, 2022. Two reviewers independently screened the literature, extracted data, and assessed the risk of bias of the included studies. Network meta-analysis was then performed using ADDIS 1.16.8, GeMTC 14.3, and Stata 15.0 software. Results A total of 13 studies involving 1 144 patients were included. There was no statistically significant difference in handgrip strength, time up to go test, gait speed, and short physical performance battery (SPPB) among different nutrient interventions. Significant differences were not found in vitamin D+ whey protein (VDWP) vs. placebo and Leu vs. placebo in handgrip strength, or VDWP vs. placebo in SPPB. The probability ranking diagram showed that the most effective of handgrip strength, time up to go test, gait speed, and SPPB were milk protein concentrate (MPC80), L-carnitime (L-Car), leucine (Leu), and MPC80, respectively. Conclusion The current evidence suggests that nutritional intervention did not significantly improve physical function in the frail elderly. MPC80, Leu, L-Car, and VDVEWP may play a role in improving the physical function of frail elderly people. Nutritional support programs that increase the above nutrients, combined with exercise training may become a better way to improve the physical function of frail elderly.
