Estimations of dietary vitamin D requirements in black and white children.

ABSTRACT:

Background

The Institute of Medicine (IOM) dietary guidelines for vitamin D are based on limited pediatric data. Our objective was to estimate the dietary vitamin D requirements for maintaining serum 25-hydroxyvitamin D [25(OH)D] concentrations at the various IOM-considered thresholds of vitamin D status (12, 16, and 20 ng/ml) during fall and winter in children.

Methods

Ninety-six healthy 8- to 14-y-old Pittsburgh-area black and white children enrolled in a randomized, placebo-controlled trial of vitamin D3 1,000 IU daily for 6 mo with baseline and 2-mo follow-up assessments completed during October through April were studied. Vitamin D intake from diet and study supplement adjusted for adherence and serum 25(OH)D were measured.

Results

The vitamin D intakes needed to
