Abstract
Objective
To systematically review evidence on the effects of nutrition therapy in older stroke patients undergoing rehabilitation and identify its effectiveness using meta-analysis.
Methods
PubMed (MEDLINE), EMBASE (via Dialog), Cochrane Central Register of Controlled Trial, World Health Organization International Clinical Trials Registry Platform and Ichu-shi Web were searched for relevant articles. Randomized controlled trials investigating the effects of nutrition therapy compared to control interventions in older stroke patients undergoing rehabilitation were considered eligible. The primary outcome was activities of daily living (ADL), and secondary outcomes were all-cause mortality, infections, pneumonia incidence, disability level, walking ability, fall, stroke recurrence, and quality of life. The risk of bias of each trial was assessed using the Cochrane Collaboration Tool, and the quality of the body of evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation approach.
Results
Eight randomized controlled trials with a total of 5484 participants were included in the meta-analysis. The meta-analysis for ADL showed no significant effects (mean difference, 4.16; 95% confidence interval [CI], -0.88 to 9.20; I2=53%, low-quality evidence). The meta-analyses for secondary outcomes revealed a significant effect of reduced infections (risk ratio, 0.65; 95% CI, 0.51 to 0.84; I2=0%; low-quality evidence), with no significant effects on the other outcomes.
Conclusion
Nutrition therapy had no statistically significant effect on ADL. However, it reduced the incidence of infections. More high-quality trials are warranted to clarify the effects of nutrition therapy in older stroke patients undergoing rehabilitation.
