Diabetes Distress Among Dyads of Patients and Their Health Supporters: Links With Functional Support, Metabolic Outcomes, and Cardiac Risk.

BACKGROUND: Patients with diabetes (PWD) often experience diabetes distress which is associated with worse self-management and glycemic control. In contrast, PWD who receive support from family and friends (supporters) have better diabetes outcomes.
PURPOSE: To examine the associations of PWD diabetes distress and supporters' distress about PWDs' diabetes with supporters' roles and PWD cardiometabolic outcomes.
METHODS: We used baseline data from 239 adults with Type 2 diabetes and their supporters participating in a longitudinal trial. PWD and supporter diabetes distress (high vs. low) were determined using the Problem Areas in Diabetes Scale-5. Outcomes included PWD-reported help from supporters with self-care activities, supporter-reported strain, PWD metabolic outcomes (glycemic control [HbA1c], systolic blood pressure [SBP], and non-HDL cholesterol) and 5 and 10 year risk of cardiac event (calculated using the United Kingdom Prospective Diabetes Study algorithm).
RESULTS: PWDs with high diabetes distress were more likely to report that their supporters helped with taking medications, coordinating medical care, and home glucose testing (p's < .05), but not more likely to report help with diet or exercise. High supporter distress was associated with greater supporter strain (p < .001). High supporter diabetes distress was associated with higher PWD HbA1c (p = .045), non-HDL cholesterol (p = .011), and 5 (p = .002) and 10 year (p = .001) cardiac risk.
CONCLUSIONS: Adults with high diabetes distress report more supporter help with medically focused self-management but not with diet and exercise. Supporter distress about PWD diabetes was consistently associated with worse outcomes. PWD diabetes distress had mixed associations with their diabetes outcomes. © Society of Behavioral Medicine 2020. All rights reserved. For permissions, please e-mail: journals.permissions@oup.com.
