Aims:
Relative fat mass (RFM) is a promising tool for identifying individuals with obesity-related health risks. Given the unclear correlation, we aimed to investigate the association between RFM and coronary artery calcification (CAC) in individuals with T2DM.
Methods:
We included hospitalized individuals aged 20-80 years with T2DM (n = 278) in this single-center cross-sectional study. We explored the correlation between RFM and the CAC score (CACS), mechanisms underlying the association between RFM and CAC, and prediction models of coronary artery stenosis (CAS).
Results:
Compared to the non-CAC group, the CAC group had a higher RFM. The CACS and RFM were positively correlated. The RFM independently increased the risk of CAC in individuals with T2DM. Using RFM to predict CAC resulted in an area under the curve of 0.598 (95 % CI [0.531-0.664], p < 0.01); RFM was not inferior to visceral fat area for predicting CAC. Insulin resistance, systolic blood pressure, and estimated glomerular filtration rate mediated the association between RFM and CAS with proportions of 9.38 %, 18.82 %, and 11.36 %, respectively.
Conclusions:
RFM was associated with CAC in individuals with T2DM. Given its potential role in predicting cardiovascular complications, incorporating RFM into clinical practice may facilitate the prevention and management of cardiovascular complications in T2DM.

Carbohydrate Metabolism
Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in...
