  • Zusammenfassung: <jats:p>Impaired awareness of hypoglycemia (IAH) has been linked to an increased rate of severe hypoglycemia (SH) in T1DM. Yet, few investigations have focused on quantifying this relationship in the context of T2DM, particularly from a pragmatic epidemiological lens. This study leverages the value of self-reported SH data to explore the real-world, population-based effect of IAH severity on SH rates in T2DM.</jats:p> <jats:p>A validated questionnaire (InHypo-DMPQ) was administered online to a nationally representative panel comprising Canadians (≥18 years) with T2DM using insulin and/or secretagogues. Data were collected on respondents’ socio-demographic/clinical traits; self-reported incidence of SH (in the past year); and IAH severity, trisected by no, moderate, and severe impairment. Multivariable negative binomial regression (NBR) analysis was used to isolate the effect of IAH on SH. A directed acyclic graph was devised to identify the minimally sufficient adjustment set.</jats:p> <jats:p>Of the 452 complete respondents (mean age: 53.2 (SD: 14.7) years; male: 56%), 6% were classified with severe IAH, 67% with moderate IAH, and 27% with no IAH. Those with severe IAH had the highest crude annual SH rate (5.89 events/person-year, 95% CI: 5.01-6.88), which over doubled and tripled the SH rate in people with moderate IAH (p&amp;lt;0.001) and no IAH (p&amp;lt;0.001), respectively. The adjusted NBR analysis revealed a statistically significant association between IAH and SH (p=0.039). Individuals with severe IAH reported an adjusted annual SH rate that was 3.23 (95% CI: 1.13-9.27, p=0.029) times greater than those with no IAH. A similar trend was observed for moderate IAH versus no IAH (p=0.038).</jats:p> <jats:p>This real-world, population-based study provides timely insight into the high prevalence of moderate and severe IAH in people with T2DM using insulin and/or secretagogues. The marked impact of IAH on increased SH rates underscores a pressing need for the clinical prioritization of IAH assessment and management in T2DM.</jats:p> <jats:sec> <jats:title>Disclosure</jats:title> <jats:p>A.
