Long‐term weight maintenance and risk of cardiometabolic multimorbidity and its subtypes in middle‐aged and older adults: A pooled landmark analysis in China and the UK

Higher TTR-BMI is an independent predictor of lower CMM risk in middle-aged and older adults, offering superior prognostic value for metabolic multimorbidity patterns. These findings highlight the clinical importance of prioritising long-term weight maintenance within a target range, rather than single time-point assessments, as a key strategy for delaying the onset of cardiometabolic disease.
