Abstract

Abstract Aims/hypothesis: To examine the impact of hypoglycaemia on daily functioning among adults with type 1 diabetes or insulin-treated type 2 diabetes, using the novel Hypo-METRICS application. RESEARCH DESIGN AND METHODS For 70 consecutive days, 594 adults (type 1 diabetes: n=274; type 2 diabetes: n=320) completed brief morning and evening Hypo-METRICS ‘check-ins’ about their experienced hypoglycaemia and daily functioning. Participants wore a blinded glucose sensor for the study duration. Days and nights with or without person-reported hypoglycaemia (PRH) and/or sensor-detected hypoglycaemia (SDH) were compared using multilevel regression models.
RESULTS Participants submitted a mean of 86.3±12.5% morning and 90.8±10.7% evening check-ins. For both types of diabetes, SDH alone had no significant associations to the changes in daily functioning scores. However, daytime and night-time PRH (with or without SDH) were significantly associated with worsening of energy levels, mood, cognitive functioning, negative affect and fear of hypoglycaemia later that day/while asleep. In addition, night-time PRH (with or without SDH) was significantly associated with worsening of sleep quality (type 1 and 2 diabetes), and memory (type 2 diabetes). Further, daytime PRH (with or without SDH), was associated with worsening of fear of hyperglycemia while asleep (type 1 diabetes), memory (type 1 and 2 diabetes) and social functioning (type 2 diabetes). CONCLUSIONS This prospective, real-world study reveals impact on several domains of daily functioning following PRH, but not following SDH alone. These data suggest that the observed negative impact is mainly driven by subjective awareness of hypoglycaemia (i.e., PRH), through either symptoms or sensor alerts/readings and/or the need to take action to prevent or treat them.
