Population
Community-based US participants aged 20-80 years with self-reported heart failure
Design
Nationally representative survey-based study across five cycles (2007-16)

Anemia burden persists in community HF; extends prior data beyond healthcare settings but leaves open whether screening alters outcomes.
Anemia affects at least 9% of community-based heart failure patients in the US, with a disproportionately higher burden in non-Hispanic Blacks and those with BMI < 25 kg/m2, and its prevalence has remained stable over a decade.
