Factors Determining the Success of Therapeutic Lifestyle Interventions in Diabetes - Role of Partner and Family Support.

Background and aims: Knowledge of therapeutic lifestyle interventions is one of the most important pillars of diabetes care; however, its incorporation in real-world settings is poor. This review evaluates the role of partner and family support in diabetes management. Methods: Literature searches were performed in PubMed, Medline and Embase for articles published before July 2018, using the terms "therapeutic lifestyle intervention" [MeSH Terms], OR "diet changes" [All Fields], OR "spousal participation" [All Fields], OR "lifestyle interventions" [All Fields], "lifestyle changes" [All Fields] AND "diabetes" [All Fields]. The search was not restricted to English-language literature; literature in Spanish, French and German were also evaluated. Results: A total of 66 of articles were reviewed, which included 33 original work, 21 review articles, and 12 systematic reviews and meta-analyses. Studies and meta-analyses have showed that if one partner has type-2 diabetes this increases the risk in other by 5-26%. Partner and family have similar diet, lifestyle, and micro- and macro-environments which could explain the similar increased risk of diabetes and non-communicable diseases. Studies have consistently shown that spousal and family support plays a key role in overcoming negative behaviours and optimising behaviours in diabetes control. Partner support has major role in prevention and control of diabetes distress, associated depression, and medication non-compliance which have an adverse impact in glycaemic outcomes. These data are predominantly available from observational studies. There is paucity of data from interventional trials evaluating effects of family and spousal participation on health, glycaemic control and quality of life. Conclusion: The support of family and spouse/partner is beneficial to improve adherence to the lifestyle interventions and pharmacotherapy required to achieve optimum glycaemic control and avoid associated complications.
