Estimated glucose disposal rate, high sensitivity C-reactive protein and cardiometabolic multimorbidity in middle-aged and older Chinese adults: A nationwide prospective cohort study.

Aim: To explore the separate and joint association of estimated glucose disposal rate (eGDR) and high-sensitivity C-reactive protein (hsCRP) with cardiometabolic multimorbidity (CMM).
Methods: A total of 6900 participants aged 45 years or older with available data on eGDR and hsCRP and without cardiometabolic diseases at baseline from the China Health and Retirement Longitudinal Study were included. CMM was defined as the coexistence of two or more cardiometabolic diseases, including heart diseases, stroke, and diabetes.
Results: During a median follow-up of 9.0 years, 464 (6.7 %) participants developed CMM. Low eGDR and high hsCRP separately and jointly increased the risk of CMM. The adjusted hazard ratio (HR) was 1.67 (95 % confidence interval [CI] 1.33-2.09) for low eGDR versus high eGDR, 1.43 (95 % CI 1.12-1.82) for high hsCRP versus low hsCRP) and 2.40 (95 % CI 1.77-3.27) for low eGDR plus high hsCRP versus high eGDR plus low hsCRP. The C-statistic, discriminatory power and risk reclassification significantly improved with the addition of combined eGDR and hsCRP for CMM (P < 0.001).
Conclusions: Low eGDR and high hsCRP were individually and jointly associated with increased risk of incident CMM. The findings highlighted the importance of joint evaluation of eGDR and hsCRP for primary prevention of CMM.
