评估美国城市中不同种族的孕妇从食物和膳食补充剂中摄取微量营养素的社会人口学相关性。使用经过验证的半定量FFQ收集的数据进行横断面分析。采用logistic回归控制孕前BMI、母亲年龄和吸烟状况，研究种族、民族和社会人口因素与微量营养素摄入量之间的关系。产前诊所，波士顿，马萨诸塞州，美国在代际压力机制规划（PRISM）研究中，分析包括孕妇（274名），这是一项城市纵向队列研究，旨在研究在控制其他环境暴露（化学压力源、营养）的情况下，压力如何影响儿童的呼吸健康。维生素E（52%）、镁（38%）、铁（57%）和维生素D（77%）缺乏的频率很高，胆碱（95%）和钾（99%）的摄入量也不理想。与多种抗氧化剂缺乏相关的因素包括西班牙裔或非裔美国人、受教育程度较低以及自我报告的与经济相关的食品不安全。与非洲裔美国人相比，西班牙裔美国人的多种甲基营养素缺乏症患病率更高；与白种人相比，他们的甜菜碱摄入量都不理想，维生素B6和铁缺乏的几率更高。几乎所有女性（98%）报告钠摄入量超过可容忍上限；还观察到过量摄入镁（35%）、叶酸（37%）和烟酸（38%）。报告这些营养素摄入过量的女性更有可能是白人或西班牙裔，受过高等教育，出生在美国，并且没有报告食物不安全。在对美国城市少数民族妇女进行围孕期饮食干预时，应考虑种族/民族和其他社会人口因素。
To assess sociodemographic correlates of micronutrient intakes from food and dietary supplements in an urban, ethnically diverse sample of pregnant women in the USA. Cross-sectional analyses of data collected using a validated semi-quantitative FFQ. Associations between racial, ethnic and sociodemographic factors and micronutrient intakes were examined using logistic regression controlling for pre-pregnancy BMI, maternal age and smoking status. Prenatal clinics, Boston, MA, USA. Analyses included pregnant women (n 274) in the PRogramming of Intergenerational Stress Mechanisms (PRISM) study, an urban longitudinal cohort designed to examine how stress influences respiratory health in children when controlling for other environmental exposures (chemical stressors, nutrition). High frequencies of vitamin E (52%), Mg (38%), Fe (57%) and vitamin D (77%) inadequacies as well as suboptimal intakes of choline (95 %) and K (99%) were observed. Factors associated with multiple antioxidant inadequacies included being Hispanic or African American, lower education and self-reported economic-related food insecurity. Hispanics had a higher prevalence of multiple methyl-nutrient inadequacies compared with African Americans; both had suboptimal betaine intakes and higher odds for vitamin B6 and Fe inadequacies compared with Caucasians. Nearly all women (98%) reported Na intakes above the tolerable upper limit; excessive intakes of Mg (35 %), folate (37 %) and niacin (38 %) were also observed. Women reporting excessive intakes of these nutrients were more likely Caucasian or Hispanic, more highly educated, US-born and did not report food insecurity. Racial/ethnic and other sociodemographic factors should be considered when tailoring periconceptional dietary interventions for urban ethnic women in the USA.
