Mayberry LS, Piette JD, Lee AA, Aikens JE. Out-of-home informal support important for medication adherence, diabetes distress, hemoglobin A1c among adults with type 2 diabetes. Journal of behavioral medicine. 2019 Jun 1; 42(3):493-501.
Adults with type 2 diabetes mellitus (T2DM) often receive self-management support from adult children, siblings or close friends residing outside of their home. However, the role of out-of-home support in patients' self-management and well-being is unclear. Patients (N? = 313) with HbA1c? > 7.5% were recruited from community primary care clinics for a mobile health intervention trial and identified an out-of-home informal support person, herein called a CarePartner; 38% also had an in-home supporter. We tested cross-sectional adjusted associations between CarePartner relationship characteristics and patients' self-management, diabetes distress, and HbA1c and whether having an in-home supporter modified these associations. Greater CarePartner closeness was associated with a greater odds of perfect medication adherence (AOR? = 1.19, p? = .029), more fruit/vegetable intake (ß? = 0.14, p? = .018), and lower diabetes distress (ß? = -?0.14, p? = .012). More frequent CarePartner contact was associated with better HbA1c among patients with an in-home supporter but with worse HbA1c among patients without an in-home supporter (interaction ß? = -?0.45, p? = .005). Emotional closeness with a CarePartner may be important for supporting T2DM self-management and reducing diabetes distress. CarePartners may appropriately engage more frequently when patients with no in-home supporter have poorly controlled diabetes.
