Other race/ethnicity group was the reference group.

*

P < .05 compared to the reference group.

P < .001 compared to the reference group.

¶Distribution of EPA and DHA were very skewed; means and standard errors of the means should be used and interpreted with caution. No test of differences in the mean intakes of EPA, DPA, and DHA between groups was performed.
