Short‐term associations between metabolic heterogeneity of obesity and cognitive frailty transitions: An ongoing Chinese elderly cohort study
Authors' conclusion
These preliminary findings emphasize the bidirectional nature of RCF transitions in Chinese older adults, highlighting its importance as an intervention window. Metabolic status demonstrates a strong association with obesity-related CF progression. MUOO correlates with irreversible decline, whereas MHOO is linked to accelerated early stage transitions. Tailored interventions targeting metabolic health in obese older adults may mitigate cognitive frailty risks and optimize outcomes.
