Abstract
The clinically standardised mindfulness-based stress reduction (MBSR) has been utilised as an intervention for improving mental health among diabetes patients The present study aimed to assess the effectiveness of mindfulness-based stress reduction (MBSR) on the mental health, haemoglobin A1c (HbA1C), and mindfulness of diabetes patients. A systematic review and meta-analysis approach was employed to review randomised controlled trials published in the English language between the inception of eight databases to July 2022. Eleven articles from 10 studies, with a combined sample size of 718 participants, were included in the systematic review, and nine studies were included in the meta-analysis. In the meta-analysis, outcomes at post-intervention and follow-up were compared between the MBSR intervention and control groups with an adjustment of the baseline values. The results showed that MBSR demonstrated effects at post-intervention and follow-up (in a period between one to 12 months with a mean length of 4.3 months) in reducing anxiety and depressive symptoms, and enhancing mindfulness, with large effect sizes. However, the effect of MBSR on reducing stress was observed at follow-up, but not at post-intervention. Effects of MBSR on HbA1C were not detected at post-intervention and follow-up. The findings suggest that MBSR appears to be an effective treatment for improving mental health conditions and mindfulness in people with diabetes. The measurement of cortisol is recommended to be used as a biological measure to evaluate the effectiveness of MBSR in diabetes patients in future research.
