Association Research between Relative Fat Mass and the Incidence Risk of Cardiometabolic Multimorbidity

Background Cardiometabolic multimorbidity (CMM) represents one of the most prevalent and stable multimorbidity patterns. Relative fat mass (RFM), as a novel anthropometric indicator for assessing adiposity, has shown promise as a predictor of individual cardiometabolic diseases. However, evidence regarding its association with the risk of CMM remains limited. Objective To investigate the association between RFM and the risk of CMM across different genders, and to evaluate the potential role of R
