背景资料：1998年，IOM建议所有有能力怀孕的妇女每天摄入400微克叶酸，以预防神经管缺陷（NTDs）。目的：本文旨在描述不同来源的叶酸如何有助于达到推荐的日常摄入量。方法：2009年，对2003-2004年和2005-2006年国家健康和营养调查中2617名15-44岁非怀孕美国妇女的数据进行了分析。通常的每日叶酸摄入量从饮食和补充剂占测量误差的比例，妇女消费的建议通常摄入量的比例，并调整协会的建议摄入量与多种特征进行了estimated.Results：总体而言，24%的非怀孕的美国育龄妇女消费的建议通常摄入量（95%CI = 20%，27%）。非西班牙裔白色妇女的摄入量最高（30%），其次是墨西哥裔美国人（17%）和非西班牙裔黑人妇女（9%）。在使用叶酸补充剂的女性中，72%（95% CI= 65%，79%）的女性摄入了推荐的日常摄入量。补充剂的使用是推荐摄入量的最强决定因素（未校正的患病率[PR]：10.2，95% CI=7.1，14.7），介导了其他特征的关联。在68%的妇女谁没有使用补充剂，消费的谷物与叶酸和糖尿病是最强的决定因素，建议通常的摄入量（PRs=20.2和0.10，分别）。结论：鉴于叶酸的消费是一个重要的公共卫生目标，以防止NTDs，战略的评估，建议妇女消费补充剂之外，是必要的。(Am J Prey Med 2010;38（5）：534-542）由Elsevier Inc.美国预防医学杂志（American Journal of Preventive Medicine）
Background: In 1998, the IOM recommended all women capable of becoming pregnant consume 400 mu g of folic acid daily to prevent neural tube defects (NTDs).Purpose: This paper aims to describe how different sources of folic acid contribute to achieving the recommended usual daily intake.Methods: Data on 2617 nonpregnant U.S. women aged 15-44 years from the 2003-2004 and 2005-2006 National Health and Nutrition Examination Surveys were analyzed in 2009. The usual daily folic acid intake from diet and supplements accounting for measurement error; the proportion of women consuming the recommended usual intake; and the adjusted associations of recommended intake with multiple characteristics were estimated.Results: Overall, 24% of nonpregnant U.S. women of childbearing age consumed the recommended usual intake (95% CI=20%, 27%). Intake was highest among non-Hispanic white women (30%), followed by Mexican-American (17%) and non-Hispanic black women (9%). Among women who used supplements with folic acid, 72% (95% CI=65%, 79%) consumed the recommended usual intake. Use of supplements was the strongest determinant (unadjusted prevalence ratio [PR]: 10.2, 95% CI=7.1, 14.7) of recommended intake, mediating associations of other characteristics. Among the 68% of women who did not use supplements, consumption of cereals with folic acid and having diabetes were the strongest determinants of recommended usual intake (PRs=20.2 and 0.10, respectively).Conclusions: Given that consumption of folic acid is an important public health goal to prevent NTDs, an evaluation of strategies, beyond recommendations that women consume supplements, is needed.
