Visual Abstract

Aim: Complex associations between T2DM, CKD and HF challenge treatment strategies and results in significant life years loss. Risk of CKD and HF in young- and usual-onset T2DM among White Caucasian (WC) and African American (AA) were explored.

Methods: From nationally representative EMRs of USA, 1491672 WC and 31133 AA diagnosed with T2DM from 2000-2018 within age 18-39 /40-49/50-59/ 60-69 yrs were identified. The restricted mean time (RMT) to CKD and HF in AA and WC were compared, adjusting for anthropometric and time-varying disease confounders.

Results: At T2DM Dx, 10 /12% and 2 /4% of WC /AA had existing CKD and HF; 48 /57% and 39 /32% had hypertension and dyslipidaemia. With mean 5 yrs follow-up, 95% CIs of CKD+HF incidence rates/1000PY were: (23-24) /(37-38) /(53-54) /(82-83) in 18-39 /40-49 /50-59/ 60-69 yrs grps for WC and (30-31) /(47-49) /(66-68) /(93-95) for AA.

Compared to WC, AA had significantly higher risk of CKD and HF across all age groups (HR CI range: 1.1-2.4). In AA/WC aged 18-39 yrs, RMT (CI) in yrs to CKD [8.3 (7.8-8.7) /8.9 (8.5-9.2)] and HF [9.4 (8.6-10.3) /11.4 (9.8-12.9)] was on average only 3.2 /3.2 yrs and 2.7 /3.3 longer compared to those aged 60-69 yrs at Dx (Fig).

Conclusion: Developing cardio-renal complications within 10 yrs of young-onset T2DM and significant higher risk among AA compared to WC call for more intense prevention strategies in young-onset population, particularly in AA.
