Associations Between Controlling Nutritional Status and Allostatic Load With Heart Failure Across Different Depressive States: A Cross-Sectional Study Using NHANES 2005–2018 Data

The CONUT and AL indices demonstrated positive associations with HF in the general population. Depressive status is a moderating factor that attenuates the association between CONUT and HF. Meanwhile, CONUT and AL are not effective predictors of HF risk under conditions of depressive status. Therefore, screening for depressive status in individuals with high CONUT and AL indices is important for predicting HF.
