Introduction: Prediabetes, characterized by elevated blood glucose, increases the risk of type II diabetes. Accessible interventions like yoga offer a holistic approach to improve metabolic health and delay disease onset.
Objective: This systematic review and meta-analysis evaluated yoga’s effects on primary outcomes; fasting blood glucose, postprandial blood glucose, glycated hemoglobin, and secondary outcome: body mass index in individuals with prediabetes.
Methods: Following PRISMA guidelines and PROSPERO registration (CRD420251017200), a search (2013–2023) identified five randomized control trail. Fasting blood glucose, postprandial blood glucose, glycated hemoglobin, and body mass index were analyzed using mean differences. Subgroup and sensitivity analyses assessed robustness. Certainty of evidence was evaluated via GRADE.
Results: Five randomized controlled trials involving 501 participants were included. The meta-analysis showed no significant effect of yoga on fasting blood glucose, with considerable heterogeneity and very low certainty evidence. No significant effects were observed for postprandial blood glucose or glycated hemoglobin, with negligible heterogeneity and low-certainty evidence. Effects on body mass index in individuals with prediabetes were non-significant with low-certainty evidence.
Discussion: Yoga did not have any clinical significance regarding Fasting blood glucose, postprandial blood glucose, glycated hemoglobin, and body mass index in individuals with prediabetes. Limited trial, small sample size, and low to very low certainty of evidence reduced confidence. Sensitivity analyses and subgroup analyses further strengthen the robustness of the findings.
Conclusion: Yoga interventions did not significantly improve primary outcomes: fasting blood glucose, postprandial blood glucose, and glycated hemoglobin, and secondary outcome body mass index.
