When analyzed by race/ethnicity, median serum folate concentrations declined significantly from 1999--2000 through 2003--2004 among all three populations considered (non-Hispanic whites [p=0.008], non-Hispanic blacks [p=0.023], and Mexican Americans [p<0.001]). The largest decrease (16%) was noted among non-Hispanic whites (Table 2). However, the median serum folate concentration was lowest among non-Hispanic blacks during all three survey periods.
Although non-Hispanic white and Mexican-American women exceeded the 2010 national health objective (objective 16-16b) for median RBC folate concentration (220 ng/mL) during all three survey periods, non-Hispanic black women had not met this objective. Trend differences from 1999--2000 through 2003--2004 in RBC folate concentrations were not statistically significant among each of the three racial/ethnic populations (non-Hispanic whites [p=0.106], non-Hispanic blacks [p=0.076], and Mexican Americans [p=0.064]).
