Independent and synergistic associations of sleep quality and frailty with cardiometabolic multimorbidity: a cross-sectional analysis in Chinese elderly population.

Sleep quality and frailty are associated with cardiometabolic multimorbidity, suggesting that their combined assessment may enhance predictive accuracy for cardiometabolic multimorbidity risk.

These findings underscore the need to prioritize high-risk elderly individuals for integrated interventions addressing sleep disturbances and frailty, thereby facilitating the transition from reactive to proactive cardiometabolic care models.
