Estimates are considered unreliable. Data have a relative standard error (RSE) greater than 30% and less than or equal to 50% and should be used with caution. Data not shown have an RSE greater than 50%.

p value less than 0.01.

p value less than 0.05.

Respondents may have used more than one nonvitamin, nonmineral dietary supplement.

The denominator used in the calculation of percentages was all sample children.

In 2007, fish oil was described as fish oil or omega-3 or DHA fatty acid. In 2012, fish oil was described as fish oil or omega-3 or DHA or EPA fatty acid.

NOTES: Estimates are based on household interviews of a sample of the civilian noninstitutionalized population. Estimates were age-adjusted using the projected 2000 U.S. population as the standard population and using two age groups: 4–11 and 12–17.
