Association between dietary intake of iron and heart failure among American adults: data from NHANES 2009-2018.

ABSTRACT: Patients with heart failure (HF) often experience iron deficiency. Intravenous iron supplementation has been widely used in clinical practice to facilitate the treatment of HF. However, the association between dietary iron intake and HF still needs to be elucidated. This study aimed to evaluate the impact of dietary iron intake on HF in American adults. The data were extracted from the National Health and Nutrition Examination Survey (NHANES) 2009-2018. Iron dietary intake data were obtained from two 24-h dietary recall interviews. We examined baseline data and HF prevalence in different quartile groups of dietary iron intake (Q1-Q4). Two logistic regression models were established to evaluate the impact of Q4 (highest iron consumption) on the risk of HF. The study included 20,853 American
