According to the 2005 March of Dimes Gallup survey, there was a decrease
in the proportion of childbearing-aged women who reported taking folic
acid in dietary supplements daily, from 40% in 2004 to 33% in 2005,
returning to a level consistent with that reported during 1995-2003.
•
These results emphasize the need for innovative programs to increase
folic acid consumption to further reduce neural tube defects (NTD).
•
Daily periconceptional consumption of 400 µg of folic acid, as
recommended by the Public Health Service since 1992, reduces the
occurrence of NTDs by 50%-70%.

• According to the
third National Health and Nutrition Examination Survey (NHANES III)
1988–94, approximately 40 percent of the U.S. population 2 months of
age and older reported taking some type of dietary supplement, and the
leading supplements taken were multivitamin/multiminerals (22 percent),
multivitamins plus vitamin C (15 percent), vitamin C as a single
vitamin (13 percent), other dietary supplements such as herbal and
botanical supplements (7 percent), and vitamin E as a single vitamin (6
percent).
• The three leading supplements used by adolescent and adult males and
adolescent and young adult females were the same as the total
population—multivitamin/multiminerals, multivitamins plus vitamin C,
and vitamin C as a single vitamin—although the order varied by sex and
age group.

• Findings from the
1999-2002 CDC's National Health and Nutrition Examination Survey (NHANES)
confirmed that blood Hg levels in young children and women of
childbearing age usually are below levels of concern.
• However, approximately 6% of childbearing-aged women had levels at or
above a reference dose, an estimated level assumed to be without
appreciable harm (>5.8 µg/L).

| • For men, average energy intake increased from 2,450 kcals to 2,618 kcals (p<0.01), and
for women, from 1,542 kcals to 1,877 kcals (p<0.01). • For men, the percentage of
kcals from carbohydrate increased between 1971-1974 and 1999-2000, from 42.4% to 49.0% (p<0.01), and for women, from 45.4% to 51.6% (p<0.01).
• The percentage of kcals from total fat decreased from 36.9% to 32.8% (p<0.01) for men
and from 36.1% to 32.8% (p<0.01) for women.
• In addition, the percentage of kcals from saturated fat decreased from 13.5% to 10.9%
(p<0.01) for men and from 13.0% to 11.0% (p<0.01) for women.
• A slight decrease was observed in the percentage of kcals from protein, from 16.5% to
15.5% (p<0.01) for men and from 16.9% to 15.1% (p<0.01) for women.
• Data from NHANES for 1971-2000 indicate similar trends. The increase in energy intake is
attributable primarily to an increase in carbohydrate intake, with a 62.4-gram increase among women (p<0.01) and a 67.7-gram increase among
men (p<0.01).
• Total fat intake in grams increased among women by 6.5 g (p<0.01) and decreased among
men by 5.3 g (p<0.01).
