Phylloquinone Intake Is Associated with Cardiac Structure and Function in Adolescents.

Background: Associations between childhood vitamin K consumption and cardiac structure and function have not been investigated.

Objective: We determined associations between phylloquinone (vitamin K-1) intake and left ventricular (LV) structure and function in adolescents.

Methods: We assessed diet with three to seven 24-h recalls and physical activity (PA) by accelerometry in 766 adolescents (aged 14-18 y, 50% female, 49% black).
