Technology Use and Diabetes Management Across Elder Age Groups in Type 1 Diabetes and Latent Auto-Immune Diabetes of the Adult (LADA), a BETTER Registry Cross-Sectional Analysis.

Objectives: Real-world data on diabetes management among a heterogenous aging population remain limited. This study aims to provide an overview of technology use and factors associated to its use, diabetes management and psychosocial aspects experienced by adults aged 50 and over living with type 1 diabetes (T1D) or latent autoimmune diabetes in adults (LADA).

Methods: This cross-sectional study analyzed data from the Canadian BETTER registry, mostly based on self-reported outcomes from individuals living with T1D or LADA. Comparative analyses were conducted across three age groups: 50-59, 60-69, and ≥70.

Results: Participants (n=674) were predominantly Caucasian (97-98% across groups) and residing in Quebec, Canada (71-79%). Insulin pump use was similar across age groups (36-39%, p=0.822), while continuous glucose monitoring (CGM) was lower among those aged ≥70 years (85% for both 50-59 and 60-69 vs 73% for ≥70 years, p=0.020). Among other factors, having private insurance and living outside of Quebec were positively associated with both insulin pump and CGM use. A high proportion (80-86%) of participants achieved an HbA1c ≤8% across all groups. Level 2 hypoglycemia events in the last month were more frequent among participants aged 50-59 years compared to those aged ≥70 years (6.9 vs 3.4, p=0.001). Level 3 hypoglycemia, social and professional support were similar between groups. Interestingly, diabetes-related distress was lower in older age groups.

Conclusions: Most individuals in this cohort adopted technology use but in lower proportion among the group aged ≥70. Overall, diabetes management was good and similar between age groups.
