PURPOSE: The aim of this study was to systematically-review published experimental studies to determine the effectiveness of behavioral interventions on self-management in Iranian adults with type 2 diabetes.
METHOD: Pub Med, Web of Science, Science Direct, Ovid Medline, EBSCO, ProQuest, Google Scholar, and the Scientific Information Database (SID) were searched for English and Persian language studies published between 2009 and 2017. The primary outcome of this review was to assess the effects of behavioral interventions on glycosylated hemoglobin. Changes in the blood pressure, Lipid profiles, BMI, Self-efficacy, knowledge, attitude, practice, Self-care behaviors, social support, anxiety, and depression were the secondary outcomes.
RESULTS: Comprehensive search procedures resulted in twenty-three experimental studies with 2208 participants. Eleven studies were included in the Meta-analysis. Compared with the control group, behavioral interventions significantly lower glycosylated hemoglobin -0.61% (95% CI -0.80, -0.41). To explore the effects of the study intervention (regarding what aspects of the intervention are most effective), we then conducted a stratified analysis for HbA1c. Larger effects were found in interventions with a longer duration and higher intensity, delivered in the group format, interventions offered to individuals with higher baseline HbA1c, and interventions delivered by a multidisciplinary team. Moreover, behavioral interventions were effective in improving blood glucose, lipid profiles, knowledge, attitude, practice, self-efficacy, quality of life, and self-care.
CONCLUSION: In line with other behavioral studies, our study shows that behavioral interventions improve self-management in Iranian adults with type 2 diabetes.
