Cardiovascular Risk Factors and Adherence to Cardiovascular Protection Practice Guidelines in Adults With Type 1 Diabetes: A BETTER Registry Cross-sectional Analysis

Cardiovascular disease (CVD) is a major cause of morbidity and mortality in people with type 1 diabetes (PWT1D). We assessed cardiovascular risk factors and pharmacologic treatment in a large Canadian cohort of PWT1D. This cross-sectional study used data from adult PWT1D in the BETTER registry (n=974). CVD risk factor status, diabetes complications and treatments (used as proxy for blood pressure and dyslipidemia) were self-reported through online questionnaires. Objective data were available for a subgroup of PWT1D (23%, n=224). Participants were adults (43.9±14.8 years) with a diabetes duration of 23.3±15.2 years; 34.8% reported glycated hemoglobin (A1C) levels of ≤7%, 67.2% reported a very high cardiovascular risk and 27.2% reported at least 3 CVD risk factors. Most participants received care for CVD in accordance with the Diabetes Canada Clinical Practice Guidelines (DC-CPG), with a median recommended pharmacologic treatment score of 75.0%. However, 3 subgroups of participants with lower adherence (
