This study sought to determine and evaluate the intakes and plasma concentrations of vitamin E (alpha-tocopherol), gamma-tocopherol, vitamin C, selenium, and carotenoids (alpha-carotene, beta-carotene, beta-cryptoxanthin, lutein/zeaxanthin, and lycopene) of nonsupplemented boys and girls, 4 to 8 years old, of Latino immigrants living in rural Nebraska.
Dietary intakes of the Latino children were estimated. Their plasma samples (fasting) were analyzed for vitamin E, vitamin C, selenium, and carotenoid concentrations. Data were evaluated by sex.
The subjects were a convenience sample of 4- to 8-year-old (n=29), apparently healthy, nonsupplemented children of Latino immigrants living in rural Nebraska.
Sex differences in parameter values were determined using general linear models; Pearson r was used for determining correlations.
No significant differences in parameter values were observed by sex, with the exception of plasma lutein/zeaxanthin concentration. The majority (69%) had plasma vitamin E (alpha-tocopherol) concentrations<0.516 mg/dL (12 micromol/L), which is indicative of vitamin E inadequacy, and over half (59%) reported consuming less than the Estimated Average Requirement for vitamin E. All subjects had plasma vitamin C and selenium concentrations indicative of adequacy (>0.41 mg/dL or >23 micromol/L, and >6.32 microg/dL or >0.8 micromol/L, respectively), and consumed at least the Recommended Dietary Allowances for these nutrients. The plasma carotenoid concentrations of the children may be useful as norms.
These children of Latino immigrants who did not take supplements had low plasma vitamin E (alpha-tocopherol) concentrations but normal plasma vitamin C and selenium concentrations.
Dietetics professionals and others involved in health care need to work with Latino immigrant parents so that their children consume adequate amounts of vitamin E.
本研究旨在测定和评估内布拉斯加州农村地区4至8岁未补充营养的拉丁裔移民男孩和女孩的维生素E（α-生育酚）、γ-生育酚、维生素C、硒以及类胡萝卜素（α-胡萝卜素、β-胡萝卜素、β-隐黄质、叶黄素/玉米黄质和番茄红素）的摄入量和血浆浓度。
估算拉丁裔儿童的膳食摄入量。分析他们的空腹血浆样本中的维生素E、维生素C、硒和类胡萝卜素浓度。数据按性别进行评估。
对象为内布拉斯加州农村地区4至8岁（n = 29）、看似健康且未补充营养的拉丁裔移民儿童的便利样本。
使用一般线性模型确定参数值的性别差异；使用Pearson r来确定相关性。
除血浆叶黄素/玉米黄质浓度外，未观察到参数值的显著性别差异。大多数（69%）儿童的血浆维生素E（α-生育酚）浓度<0.516 mg/dL（12 μmol/L），这表明维生素E摄入不足，超过一半（59%）的儿童报告其维生素E摄入量低于估计平均需求量。所有受试者的血浆维生素C和硒浓度表明摄入充足（分别>0.41 mg/dL或>23 μmol/L，以及>6.32 μg/dL或>0.8 μmol/L），并且至少摄入了这些营养素的推荐膳食摄入量。儿童的血浆类胡萝卜素浓度可作为标准值。
这些未补充营养的拉丁裔移民儿童血浆维生素E（α-生育酚）浓度较低，但血浆维生素C和硒浓度正常。
饮食专业人员和其他参与医疗保健的人员需要与拉丁裔移民父母合作，以便他们的孩子摄入足够量的维生素E。
