Data Source: 
National Health and Nutrition Examination Survey
Changed Since the Healthy People 2020 Launch: 
Baseline (Year): 
23.8 (2003–06)
Target-Setting Method: 
10 percent improvement

Number of non-pregnant women aged 15 to 44 years with usual daily total intake of folic acid of  greater than or equal to 400 micrograms


Number of non-pregnant women aged 15 to 44 years

Methodology Notes: 

    The proportion of non-pregnant women aged 15 to 44 years with usual daily folic acid intake of 400 mg or more is estimated from questionnaire and dietary recall data as part of the standard NHANES protocol. The method of calculation of dietary folic acid for this objective involves estimating the daily usual intake of synthetic folic acid from foods reported in two 24-hour dietary recalls using a specialized statistical program, PC-SIDE (Nusser et al., 1996).
