目的了解育龄妇女血清叶酸及红细胞叶酸水平,为昆明地区育龄妇女增补叶酸预防神经管畸形(NTDs)等出生缺陷提供参考。方法选取2010年1月至2011年10月于本研究所门诊就诊的261例育龄妇女为研究对象。采集其年龄、孕次等相关临床资料(本研究遵循的程序符合云南省人口和计划生育科学技术研究所人体试验委员会所制定的伦理学标准,得到该委员会批准,征得受试者知情同意,并与之签署临床研究知情同意书)。采集受试者空腹静脉血4mL,采用电化学发光法分别测定血清叶酸及红细胞叶酸水平。以预防NTDs的叶酸推荐值为标准,进行叶酸水平分析。结果 261例育龄妇女的血清叶酸、红细胞叶酸的平均水平分别为(9.74±3.23)ng/L和(529.79±205.44)ng/L,以试剂盒正常参考值为标准判断标准。本组受试者血清叶酸和红细胞叶酸缺乏率分别为8.43%(22/261)和5.36%(14/261)。若以预防NTDs推荐值为标准进行判断,则本组妇女血清叶酸、红细胞叶酸水平偏低率分别为67.82%(177/261)和73.95%(193/261)。结论昆明地区育龄妇女叶酸缺乏率不高,但仍有超过1/2以上育龄妇女的血液叶酸水平低于预防NTDs的推荐值,故对育龄妇女须加强叶酸增补方面的知识普及。 相似文献

叶酸缺乏可导致胚胎神经管畸形(NTDs)等出生缺陷。育龄妇女在怀孕时由于需要量增加以及生理机能出现很大变化等原因,容易发生叶酸缺乏。对育龄妇女孕前或孕早期补充叶酸,可有效降低NTDs的发生率,提高出生人口健康水平。许多专业组织和政府机构采取各种措施来增加育龄妇女的叶酸摄入,主要方式有富含叶酸食物的摄入、使用叶酸补充剂和叶酸强化食品等。 相似文献

<正>研究表明,育龄妇女在妊娠前3个月至孕早期3个月内每天服用0.4mg叶酸可以有效预防50%~80%神经管畸形(NTDs)的发生[1,2]。围孕期服用叶酸预防NTDs的效果不仅取决于是否服用,更重要的是取决于服用的依从性状况。向育龄妇女开展的健康教育,对于提高其对NTDs及叶酸的认知水平,降低NTDs的发生率具有重要意义[3]。海南省于2010年1月起正式实施农村妇女免费增补叶酸预防NTDs。为了解海南省农村育龄妇女对叶酸干预的知晓情况、叶酸增补依从现状及其影响因素,于2011年5月对陵水、定安两地部分农村育龄妇女进 相似文献

OBJECTIVE: To characterize risk factors for nightblindness among nonpregnant women of childbearing age, a group recently recognized to be at high risk of vitamin A deficiency in some developing countries. DESIGN: Case-control study. SETTING: The study included >15 000 households in National Micronutrient Survey of Cambodia conducted in 2000. SUBJECTS: The prevalence of nightblindness among 13 358 nonpregnant women was 2.0%. A total of 328 nonpregnant women with nightblindness were matched by province with 1009 nonpregnant women without nightblindness. METHODS: Univariate and multivariate logistic regression models were used to estimate odds ratios (ORs) as estimates of the relative risk of factors associated with nightblindness. RESULTS: In a final model, materials in the wall of the house (OR 1.4, 95% confidence interval (CI) 0.9-2.0), land ownership < or =0.5 hectares (OR 1.4, 95% CI 1.0-1.9), nightblindness in last pregnancy (OR 44.5, 95% CI 29.2-67.8), parity >3 (OR 1.5, 95% CI 1.0-2.1), diarrhea within the last 2 weeks (OR 1.9, 95% CI 1.3-2.8), maternal body mass index <18.5 (OR 1.8, 95% CI 1.2-2.7), and lack of consumption of vitamin A-rich animal foods in the last 24 h (1-60 retinol equivalents (RE) OR 1.1, 95% CI 0.7-1.6; > or =60 RE, OR 0.7, 95% CI 0.4-1.0) were associated with nightblindness among nonpregnant women. CONCLUSIONS: Women of childbearing age in Cambodia with low socioeconomic status, low consumption of vitamin A-rich animal foods, a history of nightblindness during the previous pregnancy, parity >3, malnutrition, and diarrhea have a higher risk of nightblindness.

Objective : The primary aim of this study was to estimate the impact of mandatory folic acid (FA) fortification of bread‐making flour on the FA intake of Australian women of childbearing age (16–44 years). The secondary objective was to investigate the relationship between estimated FA intake and socio‐economic status (SES) and age. Method : Dietary modelling was used to estimate FA intake under four mandatory fortification scenarios – no supplement use, supplement use unrelated to FA intake, supplement use only among the highest consumers of bread, and increased supplement use. Data were obtained from the 1995 National Nutrition Survey for food intake patterns, the 2007 Victorian Population Health Survey for FA supplement use, and a marketplace survey. Results : It is estimated that the National Health and Medical Research Council (NHMRC) recommendation for an additional 400 mg/day FA will be achieved by a minimum of 3.9, 25.4, 21.7 and 30% of the target population under scenarios 1–4, respectively. The FA upper level of intake is exceeded by a maximum of 0.1, 1.7, 6.1 and 4.1% of the target population for scenarios 1–4, respectively. Conclusions : Mandatory FA fortification is not sufficient for the NHMRC recommendations for minimum and maximum intakes to be met by all of the target population under a number of plausible behaviour scenarios. Implications : Targeted nutrition education campaigns are needed for SES and age sub‐groups and research of this nature should be extended to other population groups. Monitoring and evaluation of this policy will be important to ensure appropriate FA intake. 相似文献

OBJECTIVE: Neural tube defects (NTDs) affect about seven of every 10,000 deliveries in Texas. To reduce the risk for NTDs, women are encouraged to supplement with 400 mcg folic acid daily during their reproductive years. This study examines folic acid awareness, knowledge, and supplementation practices among women of childbearing age (WCBA), including residents of Texas-Mexico border as well as women of Hispanic origin/ethnicity, populations that have NTD rates up to three times higher than the national average. METHODS: We conducted a statewide multistage sample telephone survey among Texas women of childbearing age in 2001. In total 1,196 women age 18 to 44 were interviewed. RESULTS: About 78% of WCBA knew about folic acid, 28% knew that folic acid prevents birth defects, and 25% knew to take folic acid before pregnancy. The prevalence of daily folic acid supplementation among all women of childbearing age was 33%. Education was the strongest predictor of folic acid awareness followed by race/ethnicity and age. Significant predictors of daily folic acid supplementation were education and ethnicity. CONCLUSIONS: Our findings suggest the need for more emphases on strategies to improve the level of folic acid supplementation among low educated women, and race ethnic minority populations. 相似文献

Neural tube defects (NTDs) are serious birth defects of the spine (spina bifida) and brain (anencephaly), affecting approximately 3,000 pregnancies each year in the United States. Periconceptional consumption of the B vitamin folic acid reduces the occurrence of NTDs by 50%-70%. To prevent these defects, the U.S. Public Health Service (1992) and Institute of Medicine (1998) issued separate recommendations that all women capable of becoming pregnant consume 400 micro g of folic acid daily, and the Food and Drug Administration mandated fortification of cereal grain products with folic acid to increase women's daily intake. Fortification of the U.S. food supply with folic acid has resulted in a 26% reduction in NTDs. However, even with fortification, not all women receive adequate levels of folic acid from their diets. Therefore, increasing the use of vitamins containing folic acid remains an important component of NTD prevention. To monitor the use of vitamins containing folic acid among women of childbearing age, the Gallup Organization has conducted a series of surveys for the March of Dimes Birth Defects Foundation since 1995. This report presents results from the 2004 survey, which indicated that although no substantial increase in the proportion of women who use vitamins containing folic acid daily occurred during 1995-2003, a substantial increase was observed in 2004, with 40% of women aged 18-45 years reporting daily consumption of a vitamin containing folic acid. This report also presents information about women's dieting behaviors. Regardless of dieting status, public health programs should stress the importance of women in their childbearing years consuming 400 micro g of folic acid daily through supplements, fortified foods, and a diet containing folate-rich foods. 相似文献

Neural tube defects (NTDs) are serious birth defects of the brain (anencephaly) and spine (spina bifida) that affect approximately 3,000 pregnancies each year in the United States. In 1992, the U.S. Public Health Service recommended that all women of childbearing age in the United States capable of becoming pregnant consume 400 microg of folic acid daily to reduce their risk for having a pregnancy affected by NTDs. To assess awareness, knowledge, and behavior related to folic acid among women of childbearing age (aged 18-45 years), CDC analyzed the results of a national survey conducted annually by the Gallup Organization during the period 2003-2007. This report summarizes the results of that analysis, which indicated that, among all women of childbearing age, those aged 18-24 years had the least awareness regarding folic acid consumption (61%), the least knowledge regarding when folic acid should be taken (6%), and the lowest reported daily use of supplements containing folic acid (30%). Because women in this age group account for nearly one third of all births in the United States, promotion of folic acid consumption should be targeted to this population. 相似文献
