It is generally understood that fluctuations in blood glucose are both distressing and intrusive for people with type 1 diabetes, yet diabetes research to date has primarily relied on global, retrospective measures that cannot capture the relationships between acute blood glucose fluctuations, emotional well-being, and function in everyday life. To overcome this limitation, the proposed Function and Emotion in Everyday Life with Type 1 Diabetes (FEEL-T1D) study is the first large-scale study to integrate continuous glucose monitoring (CGM), ecological momentary assessment (EMA), and accelerometry to disentangle the short-term dynamic relationships between blood glucose, function, and emotional well-being in adults with type 1 diabetes. These analyses will contribute essential basic knowledge about these relationships that will be foundational to the individualization of treatment recommendations and development of innovative interventions that optimize both clinical and patient-reported outcomes.
