It has been known for decades that social networks are causally related to disease and mortality risk. However, this field of research and its potential for implementation into diabetes care is still in its infancy. This narrative review addresses the state-of-the-art of social network research in type 2 diabetes prevention and care.

Despite the heterogeneity of network assessments, valuable lessons can be drawn from available studies.

First, the structural network aspect ‘living alone’ and the functional network aspect ‘lack of social support’ increase type 2 diabetes risk. The latter association may be modified by lifestyle risk factors, as obesity, low level physical activity and unhealthy diet.

Second, smaller network size and less social support increase diabetes complication-risk, particularly chronic kidney disease and cardiovascular heart disease.

Third, social support better enables diabetes self-management, and social support preventive interventions lowered HbA1c values in the short-term.

However, harmonization and more detailed assessment of structural and functional social network aspects is urgently needed to utilize these aspects for more effective prevention and disease management in type 2 diabetes.
