Background: Diabetes is a chronic and prevalent disease. In recent years, its prevalence has increased because of lifestyle changes, immobility and subsequent obesity. The increase in diabetes prevalence has provoked multiple and scattered interventions by specialists and health care providers in order to control and regulate blood sugar and its related factors. The purpose of this study was to collect and integrate the results of these interventions in two fields of psychological and sport interventions and to investigate the impact of them on control of Glycosylated haemoglonin (HbA1c) in patients with diabetes by meta-analysis method.
Methods: For this purpose 38 acceptable studies (19 sport interventions and 19 psychological interventions), in terms of methodology, were selected and meta-analysis performed on them. This study is based on 38 effect sizes and research instrument is checklist of meta-analysis.
Results: The study findings showed that the effect size of psychological interventions on control of Glycosylated haemoglonbin is 0.67 (p<0.00001) and the effect size of sport interventions is 0.79 (p<0.00001).
Conclusion: according to Cohen’s chart, the effect size of both psychological and sport intervention on control of Glycosylated haemoglonin in patients with diabetes is medium. However, the effectiveness of sport interventions have been obtained more than the psychological intervention
