Strength in Partnership: The Impressive Positive Impact of Couple-Based Interventions on Glycemic Control in Type 2 Diabetes Management

Background: Social and familial support significantly improves type 2 diabetes (T2D) management, yet couple-based interventions remain underexplored. This study evaluates the effects of perceived social support, measured via the Multidimensional Scale of Perceived Social Support (MSPSS), on glycemic control, FBS, weight, and BMI among married couples with T2D. Methodology: A 90-day retrospective study involving six married couples (12 participants) enrolled in the SugarFit Diabetes Reversal and Management Program (SDRMP) was conducted over 90 days. Couples were categorized into high-support, moderate-support, and low-support groups based on MSPSS scores. Interventions included joint dietary plans, fitness routines, behavioral coaching, and emotional wellness sessions. Pre- and post-intervention measures of HbA1c, FBS, weight, and BMI were recorded. Results: Participants showed significant improvements in glycemic control and weight management. Couples receiving high/high support (both husband and wife) experienced notable HbA1c reductions (up to 3.5% in husbands, 1.8% in wives) and weight loss (up to 14.4 kg in husbands, 6.6 kg in wives), with MSPSS scores of up to 56 for husbands and 54 for wives. Moderate/moderate support led to more modest improvements (up to 0.7% HbA1c reduction and 1.4 kg weight loss in husbands, with stable weight in wives), with MSPSS scores up to 40 for husbands and 31 for wives. High/moderate support yielded intermediate results (up to 1.8% HbA1c reduction and 2 kg weight loss in husbands, 1 kg in wives), with MSPSS scores up to 47 for husbands and 39 for wives. Higher MSPSS scores were strongly correlated with greater reductions in HbA1c and weight, emphasizing the importance of spousal and family support, with couples receiving high/high support achieving the best outcomes. Conclusion: Couple-based interventions significantly improve glycemic levels and weight loss in T2D couples with high MSPSS scores. These findings emphasize the value of social support in diabetes care. Personalized interventions leveraging mutual support can enhance clinical and relational outcomes. Future research should explore long-term effects and broader demographic applicability.
