Relation of Magnesium Intake With Cardiac Function and Heart Failure Hospitalizations in Black Adults: The Jackson Heart Study.

ABSTRACT:

Background

Little is known about magnesium intake and risk of heart failure (HF) hospitalizations, particularly in blacks. We hypothesize that magnesium intake relates to HF hospitalization in blacks.

Methods and results

From the Jackson Heart Study cohort (n=5301), we studied 4916 blacks recruited during 2000 to 2004 in Jackson (Mississippi), who completed an 158-item Food-Frequency Questionnaire that included dietary supplements. Daily magnesium intake derived from the questionnaire was divided by the body weight to account for body storage and stratified by quartiles (0.522-2.308, 2.309-3.147, 3.148-4.226, and ≥4.227 mg magnesium intake/kg). Cox proportional hazards modeling assessed the association between quartiles of magnesium intake/kg and hospitalizations for HF adju
