The Cardiometabolic Index (CMI) is associated with an increased risk of obstructive sleep apnea: a population-based study

This study found a non-linear positive association between CMI and OSA risk. Specifically, the OSA risk in the Q4 group was significantly higher than that in the Q1 group (OR = 1.272, P < 0.001). Additionally, the association was more prominent in young people, females, and populations without hypertension or stroke. These findings suggest that CMI may serve as a convenient indicator for early screening, particularly applicable to high-risk OSA populations with metabolic disorders. The results of this study provide a new perspective for public health interventions and clinical risk assessment of OSA.
