MICH-15 Reduce the proportion of women of childbearing potential who have lower (below the 25th percentile) red blood cell folate concentrations
About the Data
Description of the data source, numerator, denominator, survey questions, and other relevant details about the national estimate.
Number of non-pregnant women aged 15 to 44 years with red-blood-cell (RBC) folate concentration <337 ng/mL, below the 25th percentile of RBC concentrations among this group in 2007-2010
Number of non-pregnant women aged 15 to 44 years with RBC concentrations
Lower RBC folate concentration is a population weighted estimate from the blood specimens collected from women aged 15 to 44 years as part of the standard NHANES protocol. According to data from the National Health and Nutrition Examination Survey (NHANES), median RBC folate concentrations increased substantially between 1988-94 and 1999-2000, pre- and post-fortification with folic acid, and then declined slightly in the post-fortification period (Pfeiffer et al., 2007, CDC, 2007).
